Standard Test Method for Linear Dimensional Changes of Plastics Under Accelerated Service Conditions

ASTM D4065-01 塑料动态机械特性的标准实施规程.程序报告及测定法

1.1 This practice is for general use in gathering and reporting dynamic mechanical data. It incorporates laboratory practice for determining dynamic mechanical properties of specimens subjected to various oscillatory deformations on a variety of instruments of the type commonly called dynamic mechanical analyzers or dynamic thermomechanical analyzers.1.2 This practice is intended to provide means of determining the transition temperatures, elastic, and loss moduli of plastics over a range of temperatures, frequencies, or time, by free vibration and resonant or nonresonant forced vibration techniques. Plots of elastic and loss moduli are indicative of the viscoelastic characteristics of a plastic. These moduli are functions of temperature or frequency in plastics, and change rapidly at particular temperatures or frequencies. The regions of rapid moduli change are normally referred to as transition regions.1.3 The practice is primarily useful when conducted over a range of temperatures from -160176;C to polymer degradation and is valid for frequencies from 0.01 to 1000 Hz.1.4 This practice is intended for materials that have an elastic modulus in the range from 0.5 MPa to 100 GPa (73 psi to 1.5 x 10 7 psi).1.5 Apparent discrepancies may arise in results obtained under differing experimental conditions. Without changing the observed data, reporting in full (as described in this practice) the conditions under which the data were obtained will enable apparent differences observed in another study to be reconciled.1.6 Test data obtained by this practice are relevant and appropriate for use in engineering design.1.7 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 practice to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 8.Note 18212;This practice is technically equivalent to ISO 6721, Part 1.

Note 18212;Sheet stock less than 3 mm (0.125 in.) but more than 1 mm (0.040 in.) in thickness may be tested by use of a composite sample having a minimum thickness of 3 mm. The laminae must be of uniform stress distribution. One type of composite specimen has been prepared by cementing the ends of the laminae together and then smoothing the edges with sandpaper. The direction of loading shall be perpendicular to the edges of the individual laminae. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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.

Standard Test Methods for Physical Dimensions of Solid Plastics Specimens

ASTM D638-01 塑料拉伸特性的标准试验方法

1.1 This test method covers the determination of the tensile properties of unreinforced and reinforced plastics in the form of standard dumbbell-shaped test specimens when tested under defined conditions of pretreatment, temperature, humidity, and testing machine speed.1.2 This test method can be used for testing materials of any thickness up to 14 mm (0.55 in.). However, for testing specimens in the form of thin sheeting, including film less than 1.0 mm (0.04 in.) in thickness, Test Methods D882 is the preferred test method. Materials with a thickness greater than 14 mm (0.55 in.) must be reduced by machining.1.3 This test method includes the option of determining Poisson's ratio at room temperature. Note 18212;This test method and ISO 527-1 are technically equivalent. Note 28212;This test method is not intended to cover precise physical procedures. It is recognized that the constant rate of crosshead movement type of test leaves much to be desired from a theoretical standpoint, that wide differences may exist between rate of crosshead movement and rate of strain between gage marks on the specimen, and that the testing speeds specified disguise important effects characteristic of materials in the plastic state. Further, it is realized that variations in the thicknesses of test specimens, which are permitted by these procedures, produce variations in the surface-volume ratios of such specimens, and that these variations may influence the test results. Hence, where directly comparable results are desired, all samples should be of equal thickness. Special additional tests should be used where more precise physical data are needed.Note 38212;This test method may be used for testing phenolic molded resin or laminated materials. However, where these materials are used as electrical insulation, such materials should be tested in accordance with Test Methods D229 and Test Method 651.Note 48212;For tensile properties of resin-matrix composites reinforced with oriented continuous or discontinuous high modulus >20-GPa (>3.0 106-psi) fibers, tests shall be made in accordance with Test Method D3039/D3039M.1.4 Test data obtained by this test method are relevant and appropriate for use in engineering design.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.

ASTM D5279-01 塑料扭力的动力机械性能测量的标准试验方法

This test method provides a simple means of characterizing the thermomechanical behavior of plastics materials using very small amounts of material. The data obtained may be used for quality control, research and development, and establishment of optimum processing conditions. Dynamic mechanical testing provides a sensitive method for determining thermomechanical characteristics by measuring the elastic and loss moduli as a function of frequency, temperature, or time. Plots of moduli and tan delta of a material versus temperature provide graphical representations indicative of functional properties, effectiveness of cure (thermosetting resin system), and damping behavior under specified conditions. This test method can be used to assess 5.3.1 The modulus as a function of temperature, 5.3.2 The modulus as a function of frequency, 5.3.3 The effects of processing treatment, including orientation, 5.3.4 Relative resin behavioral properties, including cure and damping, 5.3.5 The effects of substrate types and orientation (fabrication) on elastic modulus, and 5.3.6 The effects of formulation additives that might affect processability or performance.1.1 This test method covers the use of dynamic mechanical instrumentation for gathering and reporting the viscoelastic properties of thermoplastic and thermosetting resins and composite systems in the form of rectangular specimens molded directly or cut from sheets, plates, or molded shapes. The torsional data generated may be used to identify the thermomechanical properties of a plastics material or composition.1.2 This test method is intended to provide means for determining the modulus as a function of temperature of plastics using nonresonant forced-vibration techniques, as outlined in Practice D 4065. Plots of the elastic (storage), loss (viscous), and complex moduli and tan delta, as a function of frequency, time, or temperature are indicative of significant transitions in the thermomechanical performance of the polymeric material system.1.3 This test method is valid for a wide range of frequencies, typically from 0.01 to 100 Hz.1.4 Apparent discrepancies may arise in results obtained under differing experimental conditions. These apparent differences from results observed in another study can usually be reconciled without changing the observed data by reporting in full (as described in this test method) the conditions under which the data were obtained.1.5 Test data obtained by this test method are relevant and appropriate for use in engineering design.1.6 The values stated in SI units are to be regarded as standard.1.7 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;There is no similar or equivalent ISO standard.

ASTM D2990-01 塑料的拉伸、压缩、弯曲蠕变及蠕变断裂的标准试验方法

Data from creep and creep-rupture tests are necessary to predict the creep modulus and strength of materials under long-term loads and to predict dimensional changes that may occur as a result of such loads. Data from these test methods can be used: (1) to compare materials, (2) in the design of fabricated parts, (3) to characterize plastics for long-term performance under constant load, and ( 4) under certain conditions, for specification purposes. Before proceeding with this test method, reference should be made to the specification of the material being tested. Any specimen preparation, conditioning, dimensions, and/or testing parameters covered in the material specification shall take precedence over those mentioned in this test method, except in cases where to do so would conflict with the purpose for conducting testing. If there are no material specifications, then the default conditions apply.1.1 These test methods cover the determination of tensile and compressive creep and creep-rupture of plastics under specified environmental conditions (see 3.1.3). 1.2 While these test methods outline the use of three-point loading for measurement of creep in flexure, four-point loading (which is used less frequently) can also be used with the equipment and principles as outlined in Test Methods D790. 1.3 For measurements of creep-rupture, tension is the preferred stress mode because for some ductile plastics rupture does not occur in flexure or compression. 1.4 Test data obtained by these test methods are relevant and appropriate for use in engineering design. 1.5 The values stated in SI units are to be regarded as the standard. The values 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.

ASTM F2003-00 超高分子量聚乙烯加速老化的标准指南

1.1 It is the intent of this guide to permit an investigator to investigate the oxidative stability of ultra-high molecular weight polyethylene (UHMWPE) materials as a function of processing and sterilization method. This guide describes a laboratory test method for accelerated aging of UHMWPE specimens and components for total joint prostheses. The UHMWPE is aged at elevated temperatures and, alternatively, at elevated partial pressures of oxygen, to accelerate oxidation of the material and thereby allow for the evaluation of its long-term chemical and mechanical stability.1.2 Although the accelerated-aging test methods described by this guide will permit an investigator to compare the oxidative stability of UHMWPE, it is recognized that these test methods may not precisely simulate the degradative mechanisms for an implant during real-time shelf aging and implantation. However, these accelerated oxidation methods have been successfully used to rank UHMWPE materials for their long-term oxidative stability.1.3 The accelerated aging test methods specified herein have been validated based on oxidation levels exhibited by certain shelf-aged UHMWPE components packaged in air and sterilized with gamma radiation. The methods have not been shown to be representative of shelf aging when the UHMWPE is packaged in an environment other than air. For example, these test methods have not been directly correlated with the shelf life of components that have been sealed in a low-oxygen package, such as nitrogen.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.

The continuous recording of torque and temperature while going through these various stages can be used to predict the behavior of the material during processing. The torque rheometer test has two important functions. First, it is a means to predict flow/viscosity and cure characteristics of pourable thermosetting compounds. For example, the test provides useful data to predict the processibility of a material in a particular molding method. This information is also useful to optimize process conditions for a particular material such as the minimum pressure to fill a mold and the time to cure a part. A second capability of the test is to provide a graphic record of the batch-to-batch uniformity of the molding compound.1.1 This test method covers the apparatus, and a specific test method, including the evaluation of results required for the determination of the thermal flow and cure behavior properties of pourable thermosetting materials. 1.2 This test method can be used: 1.2.1 As a control for the development and production of pourable thermosetting materials and to measure the different properties (for example, melting behavior, cure behavior, etc.) as well as the influence of various additives and fillers in any given formulations, and1.2.2 Verify the uniformity of different production batches of the same formulation.1.3 The values are stated in SI units.This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM D792-00 用位移法测定塑料密度和比重(相关密度)的标准试验方法

The specific gravity or density of a solid is a property that can be measured conveniently to identify a material, to follow physical changes in a sample, to indicate degree of uniformity among different sampling units or specimens, or to indicate the average density of a large item. Changes in density of a single specimen may be due to changes in crystallinity, loss of plasticizer, absorption of solvent, or to other causes. Portions of a sample may differ in density because of difference in crystallinity, thermal history, porosity, and composition (types or proportions of resin, plasticizer, pigment, or filler). Note 68212;Reference is made to Test Method D 1622. Density is useful for calculating strength-weight and cost-weight ratios. 1.1 These test methods describe the determination of the specific gravity (relative density) and density of solid plastics in forms such as sheets, rods, tubes, or molded items. 1.2 Two test methods are described: 1.2.1 Test Method A --For testing solid plastics in water, and 1.2.2 Test Method B--For testing solid plastics in liquids other than water.Note 1--Alternatively, Test Method D1505 may be applied to many such forms, as well as to films and sheeting. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 This standard does not purport to address all of the safety problems, if any, associated with its use.
