ASTM D6324-11 合成材料制男用避孕套标准试验方法

New polymer materials for male condoms are being developed. This standard is intended to describe the test methods whose results shall adequately describe the design and the quality of condoms made of polyurethane material. These test methods are not intended to be design restrictive. The condom design shall be validated prior to use.1.1 These test methods cover and shall be used to evaluate male condoms made only of polyurethane. These test methods also describe the minimum inspection and quality levels that shall be utilized in referee tests. It is not intended to be a routine quality control specification for polyurethane condom manufacturing operations. 1.2 These test methods are intended to assist buyers in obtaining polyurethane condoms of consistent quality. The safe and proper use of polyurethane condoms is excluded from the scope of these test methods. 1.3 The annexes in these test methods include important information, such as that on apparatus or materials, that is a mandatory part of these test methods but too detailed for inclusion in the main text. 1.4 The appendixes in these test methods contain information intended to provide guidance. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A1.1.1 This annex covers the method for determining the length of polyurethane male condoms. A2.1.1 This appendix covers the test method for determining the tensile properties of polyurethane condoms. Specimen elongation may be measured by extension indicators or displacement of gauge marks. A4.1.1 Experience has shown that the water leakage test is most sensitive when the condom is filled while hanging vertically, its top is closed off, and the condom is placed in a horizontal position while it is examined for leaks. With this technique, the internal pressure over the entire condom surface is approximately uniform. X1.1.1 This appendix covers the methods for determining the thickness of polyurethane male condoms. X2.1.1 This appendix outlines a test method for determining the bursting volume and bursting pressure of polyurethane condoms. This test method is patterned after standard methods typically used in determining the air inflation properties of latex condoms. The testing apparatus and the procedure may not be appropriate for all types of polyurethane materials and product designs, and, therefore, it is inappropriate to establish a minimum requirement for volume. X2.1.2 Following a more extensive review of existing and proposed polyurethane condom products, it may be more appropriate to categorize the marketed products by material type and design, and to develop separate test methods for each, after which, appropriate minimum requirements for volume can be established, consistent with the physical properties of the individual material types. X3.1.1 This appendix covers the test method for determining the strength of welded seams of polyurethane condoms.

ASTM D4020-11 超高分子量聚乙烯模制和挤压材料的标准规格

1.1 This specification provides for the identification of virgin, natural color, unmodified homopolymer ultra-high-molecular-weight polyethylene (UHMW-PE) plastics molding and extrusion materials. This identification is made in such a manner that the seller and purchaser can agree on the acceptability of different commercial lots or shipments. 1.2 This specification also provides guidance for the characterization of UHMWPE materials based on various mechanical, thermal, electrical, and other analyses. 1.3 It is not intended to differentiate between various molecular weight grades of ultra-high-molecular-weight polyethylene commercially available. 1.4 It is not the function of this specification to provide specific engineering data for design purposes. 1.5 Ultra-high-molecular-weight polyethylenes, as defined in this specification, are those linear polymers of ethylene which have a relative viscosity of 1.44 or greater, in accordance with the test procedures described herein. 1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.7 The following precautionary caveat pertains only to the test method portions in Section 7 and the Annex and Appendixes, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 18212;This standard and ISO 11542-1 address the same subject matter, but differ in technical content. ISO 11542-1 provides a classification system based on various characteristics and a range of viscosity numbers determined in accordance with ISO 1628-3. X2.1.1 This test method covers determination of the impact strength of UHMW-PE, which is extremely impact resistant. When tested in accordance with Test Method D256, Method A, UHMW-PE generally gives the NBF type of failure, rendering the test result invalid. This test method specifies the same type of pendulum impact test machine as that given in Test Method D256 but introduces a much higher degree of stress concentration into the specimen by double notching with a razor blade. Application of this test method shall be limited to the characterization of virgin, unmodified UHMW-PE resins, not commercially processed products. It is advised that the user be familiar with Test Method D256 before attempting to use this test method. X2.1.2 The values stated in SI units are to be regarded as the standard. Note X2.18212;This test method and Annex B of ISO 11542-2 address the same subject matter, but differ in technical content and results shall not be compared between the two test methods. X4.1.1 This test method covers the determination of elongational stress as a characterization of the melt viscosity of UHMW-PE. The melt flow rate in accordance with test method D1238 cannot be determined for this material because ultra high molecular weight polyethylene does not have a melt flow. The elongational stress is also be referred to as ZST and flow value, or both. X4.1.2 Application of this test method shall be limited to virgin, unmodified resin. The elongational s......

Standard Specification for Polybutylene (PB) Plastics Molding and Extrusion Materials

ASTM D1896-09 热固性混合料传递成型试样的标准实施规程

Transfer molding is particularly suited to thermosetting materials of intermediate plasticity. Fixed molding parameters cannot be specified for each type of material. Molding compounds of the same type come in many different plasticities measured in accordance with Test Methods D731, D3123, and D3795. Consequently, for a given material type, the molding parameters required to produce satisfactory test specimens will often vary dependent on the plasticity of the specific material grade. The mold shown in this practice provides for a set of five specimens. However, if only certain specimens are desired, the other cavities can be blocked by inserting gate blanks. Typically, breathing of the mold is not required to release trapped volatile matter as the gas is free to flow from the vent end of the mold. This is a particular advantage for heat-resistant compounds and reduces the tendency for molded specimens to blister at high exposure temperatures. Flow and knit lines in a molded piece are often sites of mechanical or electrical weakness and can be found in some degree of severity throughout the molded piece. The semisolid molding compound passing through the gate is subject to non-Newtonian flow and, consequently, wrinkles and folds as it travels down the mold cavity. Fibers and other reinforcements in the molding compound align with the flow pattern and, consequently, can orient perpendicular to the axis of the bar at the center and parallel at the surface of the bar. Mold temperature, thermal conductivity and plasticity of the molding compound, degree of preheat, and plunger pressure are parameters that influence the time to fill the mold cavities and the formation of knit lines. Note 38212;If the temperature of the mold is held constant and the plunger pressure varied for a designated thermosetting molding compound, two extreme characteristic conditions can be obtained. If the pressure is low, then the vent end of the cavity will not fully fill, and weld lines will form by incomplete knitting of the material. If the pressure is too high, the mold cavity will fill fast, the outside of the specimen will case harden while the pressure is still forcing material out the vent, and a ball-and-socket grain structure will be obtained. A ball-and-socket structure is an indication of the molding condition, and lower test data will result. Thermosetting compounds containing long-fiber fillers such as glass roving, chopped cloth, or shavings can be used but are not recommended for transfer molding. These filler materials tend to break, tear, or ball in passing through the gates of the mold, thereby not optimizing their potential strength. The Izod impact strength of transfer molded specimens of molding compounds containing short fibers will generally be lower than the values obtained using compression-molding methods. Quite often the impact strength will vary along the axis of the bar due to molding parameters, flow pattern, and fiber orientation. The flexural and tensile strength of transfer molded specimens of molding compounds containing short fibers will generally be higher than the values obtained using compression-molding methods. Flexural tests are particularly sensitive to transfer molding due to the thin resin skin formed at the surface of the bar during the final filling of the cavity and pressure buildup.1.1 This practice covers a general procedure for the transfer molding of mechanical and electrical test specimens of thermosetting molding materials. Note 18212;The utility ......

Standard Practice for Transfer Molding Test Specimens of Thermosetting Compounds

ASTM F2787-09 热塑波纹壁雨水收集室结构设计的标准实施规程

This practice provides a rational method for structural design of thermoplastic stormwater chambers. The loads, capacities, and limit states are based on accepted load and resistance factor design for thermoplastic pipes; however, existing design specifications for thermoplastic pipes do not adequately address the design of chambers due to (1) open-bottom geometry, (2) support on integral foot, (3) varying circumferential corrugation geometry, and (4) manufacture with alternative thermoplastic resin. This practice standardizes recommendations for designers to adequately address these aspects of chamber design. This practice is written to allow chamber manufacturers to evaluate chambers meeting existing classifications and to design chambers for new classifications as they are developed.1.1 This practice standardizes structural design of thermoplastic corrugated wall arch-shaped chambers used for collection, detention, and retention of stormwater runoff. The practice is for chambers installed in a trench or bed and subjected to earth and live loads. Structural design includes the composite system made up of the chamber arch, the chamber foot, and the soil envelope. Relevant recognized practices include design of thermoplastic culvert pipes and design of foundations. 1.2 This practice standardizes methods for manufacturers of buried thermoplastic structures to design for the time dependent behavior of plastics using soil support as an integral part of the structural system. This practice is not applicable to thermoplastic structures that do not include soil support as a component of the structural system. 1.3 This practice is limited to structural design and does not provide guidance on hydraulic, hydrologic, or environmental design considerations that may need to be addressed for functional use of stormwater collection chambers. 1.4 Stormwater chambers are most commonly embedded in open graded, angular aggregate which provide both structural support and open porosity for water storage. Should soils other than open graded, angular aggregate be specified for embedment, other installation and functional concerns may need to be addressed that are outside the scope of this practice. 1.5 Chambers are produced in arch shapes to meet classifications that specify chamber rise, chamber span, minimum foot width, minimum wall thickness, and minimum arch stiffness constant. Chambers are manufactured with integral footings. 1.6 Polypropylene chamber classifications are found in Specification F 2418. Specification F 2418 also specifies chamber manufacture and qualification. 1.7 This practice is applicable to design in inch-pound units. The SI units in parenthesis are given for information only. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D3123-09 低压热固性模制化合物的螺线流的试验方法

The spiral flow of a thermosetting molding compound is a measure of the combined characteristics of fusion under pressure, melt viscosity, and gelation rate under specific conditions. This test method is useful as a quality control test and as an acceptance criterion. This test method, by itself, is not a valid means for comparing the moldability of similar or different molding compounds because it cannot duplicate actual conditions prevalent in different types of production molds. This test method is presently intended for use at a transfer pressure of 6.9 MPa (1000 psi) and a mold temperature of 423 ± 3 K (150 ± 3°C (302 ± 5°F)).1.1 This test method covers a procedure for measuring the spiral flow of thermosetting molding compounds (soft or very soft) designed for molding pressures under 6.9 MPa (1000 psi). It is especially suited for those compounds used for encapsulation or other low pressure molding techniques. It involves the use of a standard spiral flow mold in a transfer molding press under specified conditions of applied temperature and pressure with a controlled charge mass. 1.2 The values stated in SI units are to be regarded as standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D7258-09 聚合物桩木的标准规范

1.1 This specification addresses the use of round and rectangular cross-section polymeric piles in axial and lateral load-bearing applications, including but not limited to marine, waterfront, and corrosive environments. 1.2 This specification is only applicable to individual polymeric pile products. Sheet pile and other mechanically connected polymeric pile products using inter-locking systems, are not part of this specification. 1.3 The piling products considered herein are characterized by the use of polymers, whereby (1) the pile strength or stiffness requires the inclusion of the polymer, or (2) a minimum of fifty percent (50 %) of the weight or volume is derived from the polymer. The type classifications of polymeric piles described in Section 4 show how they can be reinforced by composite design for increased stiffness or strength. 1.4 This specification covers polymeric piles fabricated from materials that are virgin, recycled, or both, as long as the finished product meets all of the criteria specified herein. Diverse types and combinations of inorganic filler systems are permitted in the manufacturing of polymeric piling products. Inorganic fillers include such materials as talc, mica, silica, wollastonite, calcium carbonate, etc. Pilings are often placed in service where they will be subjected to continuous damp or wet exposure conditions. Due to concerns of water sensitivity and possible affects on mechanical properties in such service conditions, organic fillers, including lignocellulosic materials such as those made or derived from wood, wood flour, flax shive, rice hulls, wheat straw, and combinations thereof, are not permitted in the manufacturing of polymeric piling products. 1.5 The values are stated in inch-pound units as these are currently the most common units used by the construction industry. 1.6 Polymeric piles under this specification are designed using design stresses determined in accordance with Test Methods D 6108, D 6109, and D 6112 and procedures contained within this specification unless otherwise specified. 1.7 Although in some instances it will be an important component of the pile design, frictional properties are currently beyond the scope of this document. 1.8 Criteria for design are included as part of this specification for polymeric piles. Certain Types and sizes of polymeric piles will be better suited for some applications than others. Polymeric piles designed and manufactured under the different Type classifications as defined within this specification will, as a whole, exhibit a wide-range of mechanical properties. For example, a 10-in. diameter Type II, chopped glass fiber reinforced high-density polyethylene (HDPE) pile will likely have an apparent stiffness much different than a 10-in. diameter Type V, glass fiber reinforced composite tube filled with concrete. Similarly, the ultimate moment capacity of these two example piles will also likely be significantly different from each other. Use of a licensed Professional Engineer is, therefore, highly recommended for designing and selecting polymeric piles in accordance with this specification. 1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

A2.1.1 This appendix covers the test method for determining the tensile properties of polyurethane condoms. Specimen elongation may be measured by extension indicators or displacement of gauge marks. A4.1.1 Experience has shown that the water leakage test is most sensitive when the condom is filled while hanging vertically, its top is closed off, and the condom is placed in a horizontal position while it is examined for leaks. With this technique, the internal pressure over the entire condom surface is approximately uniform. X1.1.1 This appendix covers the methods for determining the thickness of polyurethane male condoms. X2.1.1 This appendix outlines a test method for determining the bursting volume and bursting pressure of polyurethane condoms. This test method is patterned after standard methods typically used in determining the air inflation properties of latex condoms. The testing apparatus and the procedure may not be appropriate for all types of polyurethane materials and product designs, and, therefore, it is inappropriate to establish a minimum requirement for volume. X2.1.2 Following a more extensive review of existing and proposed polyurethane condom products, it may be more appropriate to categorize the marketed products by material type and design, and to develop separate test methods for each, after which, appropriate minimum requirements for volume can be established, consistent with the physical properties of the individual material types. X3.1.1 This appendix covers the test method for determining the strength of welded seams of polyurethane condoms.

ASTM D7486-08(2013)e1 采用湿法分析法测量塑料粒上的细粒和粉尘颗粒的标准试验方法

5.1 Molding and extruding plastic pellets require dust free, dry pellets to prevent processing problems. Plastic producers try to remove the dust and streamers with dust removal systems prior to packaging and loading. How to accurately measure dust and streamer content in plastic pellets is an important quality control issue. 5.2 Particle size analysis is used to determine a percentage of particle size distribution from a representative sample of the whole. In terms of size analysis concerning plastic pellets, sieving is used to determine the dust content in the range of 500 to 2000 micron. Test Method D1921, Test Method B, is used to determine this type of particle sizing. 5.3 After dry sieve analysis, particles smaller than 500 microns need to be analyzed by wet method. A fresh sample shall be used for wet analysis. This test method allows washing down the fines attached to the pellets by electrostatic forces. 5.4 The wet analysis provides accurate quantification of small to large amounts of fines, negating static effects, and eliminating detrimental effects of mechanical agitation. A wet analysis must be employed to accurately quantify lower PPM dust levels in plastic pellets. 1.1 This test method measures the amount of fine particles adhered on plastic pellets or granules in which they are commonly produced and supplied. The lower limit of this test method is restricted only by the porosity of the filter disc used to capture the particle size being quantified. 1.2 The wet analysis technique allows for separation and collection of statically charged particles by liquid wash and filtration methods. This must be performed under standard laboratory conditions. 1.3 The values stated in SI units are to be regarded as standard. 1.4 This test method describes an essential practice to check the quality of plastics once the production cycle is terminated and to evaluate the performance of pellet cleaning systems or of the special pneumatic conveying systems for the distinct size fractions below 500 micron only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.Note 1—There is no known ISO equivalent to this standard.

ASTM D5364-08 燃煤单位玻璃纤维增强塑料烟囱衬里的设计,制造及安装标准导则

This guide provides information, requirements and recommendations for design professionals, fabricators, installers and end-users of FRP chimney liners. FRP is a cost-effective and appropriate material of construction for liners operating at moderate temperatures in a corrosive chemical environment. This guide provides uniformity and consistency to the design, fabrication, and erection of fiberglass-reinforced plastic (FRP) liners for concrete chimneys with coal-fired units. Other fossil fuels will require a thorough review of the operating and service conditions and the impact on material selection. This guide is limited specifically to FRP liners within a supporting concrete shell and is not applicable to other FRP cylindrical structures. 1.1 This guide offers direction and guidance to the user concerning available techniques and methods for design, material selection, fabrication, erection, inspection, confirmatory testing, quality control and assurance. 1.2 These minimum guidelines, when properly used and implemented, can help ensure a safe and reliable structure for the industry. 1.3 This guide offers minimum requirements for the proper design of a FRP liner once the service conditions relative to thermal, chemical, and erosive environments are defined. Due to the variability in liner height, diameter, and the environment, each liner must be designed and detailed individually. 1.4 Selection of the necessary resins and reinforcements, composition of the laminate, and proper testing methods are offered. 1.5 Once the material is selected and the liner designed, procedures for proper fabrication of the liner are developed. 1.6 Field erection, sequence of construction, proper field-joint preparation, and alignment are reviewed. 1.7 Quality control and assurance procedures are developed for the design, fabrication, and erection phases. The quality-assurance program defines the proper authority and responsibility, control of design, material, fabrication and erection, inspection procedures, tolerances, and conformity to standards. The quality-control procedures provide the steps required to implement the quality-assurance program. 1.8 Appendix X1 includes research and development subjects to further support recommendations of this guide. 1.9 Disclaimer8212;The reader is cautioned that independent professional judgment must be exercised when data or recommendations set forth in this guide are applied.
