1.1 This specification covers the establishment of requirements for homopolymers of vinyl chloride in original powder form intended for subsequent mixing and processing in thermoplastic compositions. These resins have a nominal specific gravity of 1.4 and a theoretical chlorine content of 56.8 %. 1.2 Two types of resin have been recognized: general purpose and dispersion. When mixed with the customary amount of plasticizer, general-purpose resins yield a dry or moist powder while dispersion resins yield a liquid slurry. Since many resins are polymerized to meet special requirements, a system of classification has been provided that permits a wide choice of grades. 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. 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 1264 – 1980 address the same subject matter, but differ in technical content (and results cannot be directly compared between the two test methods.)

Presence of even low concentrations of PVC in recycled PET flakes may result in equipment corrosion problems during processing. The level of PVC contamination may also dictate the market for use of the recycled polymer in secondary products. Procedures presented in this practice are used to identify and, if desired, estimate the concentration of PVC contamination in recycled PET flakes.1.1 This practice covers four procedures for separation and qualitative identification of poly(vinyl chloride) (PVC) contamination in poly(ethylene terephthalate) (PET) flakes. Note 18212;Although not presented as a quantitative method, procedures presented in this practice may be used to provide quantitative results at the discretion of the user. The user assumes the responsibility to verify the reproducibility of quantitative results. Data from an independent source suggest a PVC detection level of 200 ppm (w/w) based on an original sample weight of 454 g. 1.2 Procedure A is based on different fluorescence of PVC and PET when these polymers are exposed to ultraviolet (UV) light. 1.3 Procedure B is an oven test based upon the charring of PVC when it is heated in air at 235°C. 1.4 Procedures C and D are dye tests based on differential staining of PVC and PET. Note 28212;Other polymers (for example, PETG) also absorb the stain or brightener. Such interferences will result in false positive identification of PVC as the contaminant. 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. For specific hazards see Section 8. Note 38212;There is no known ISO equivalent to this practice.

The methanol extract test is most commonly employed with paste- or dispersion-type vinyl resins intended for organosol or plastisol applications. The test result is a quantitative measure of the methanol-soluble, nonvolatile, essentially nonpolymeric content of the virgin, unmodified resin. The major ingredient removed is the soap system employed in the polymerization reaction; methanol extract provides a measure of lot-to-lot uniformity of the resin in this respect.1.1 This test method covers the determination of the methanol extract, or nonvolatile methanol-soluble portion, of vinyl chloride resins. 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.

This test method provides a guide for evaluating the moldability of thermosetting molding powders. This test method does not necessarily denote that the molding behavior of different materials will be alike and trials may be necessary to establish the appropriate molding index for each material in question. The sensitivity of this test diminishes when the molding pressure is decreased below 764 psi (5.3 MPa), so pressures lower than this are not ordinarily recommended. This is due to the friction of moving parts and the insensitivity of the pressure switch actuating the timer at these low pressures.1.1 This test method covers the measurement of the molding index (plasticity) of thermosetting plastics ranging in flow from soft to stiff by selection of appropriate molding pressures within the range from 530 to 5300 psi (3.7 to 36.5 MPa). 1.2 The values stated in inch-pound units are to be regarded as standard.

Knowledge of the peroxide content of uncured PE and EVA samples is required to regulate the degree of crosslinking in the cured product. As end use applications of the cured product can be affected by residual amounts of the peroxide or its decomposition products—dimethylbenzyl alcohol and acetophenone—knowledge of these levels is also important. This test method provides a procedure for determining the concentration of these compounds. A method for the HPLC assay of dicumyl peroxide is described in Test Method E 755.1.1 This test method covers and is applicable to the determination of dicumyl peroxide and the decomposition products dimethylbenzyl alcohol and acetophenone in cured and uncured polyethylene (PE) and ethylene vinyl acetate (EVA) resins. These uncured polymers normally contain from 1 to 2 % dicumyl peroxide, whereas the residual peroxide level in the cured polymers is usually less than 0.1 %. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.3 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This test method provides a simple means of characterizing the cure behavior of thermosetting resins using very small amounts of material (fewer than 3 to 5 g). 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 cure characteristics by measuring the elastic and loss moduli as a function of temperature or time, or both. Plots of cure behavior and tan delta of a material versus time provide graphical representation indicative of cure behavior under a specified time-temperature profile. This test method can be used to assess the following: Cure behavior, including rate of cure, gel, and cure time. Processing behavior, as well as changes as a function of time/temperature. Note 38212;The presence of the substrate prevents an absolute measure, but allows relative measures of flow behavior during cure. The effects of processing treatment. Relative resin behavioral properties, including cure behavior and damping. The effects of substrate types on cure. Note 48212;Due to the rigidity of a supporting braid, the gel time obtained from dynamic mechanical traces will be longer than actual gel time of the unsupported resin measured at the same frequency. This difference will be greater for composites having greater support-to-polymer rigidity ratios. Effects of formulation additives that might affect processability or performance. For many materials, there may be a specification that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that material specification before using this test method. Table 1 of Classification System D 4000 lists the ASTM materials standards that currently exist.1.1 This test method covers the use of dynamic-mechanical-oscillation instrumentation for gathering and reporting the thermal advancement of cure behavior of thermosetting resin. It may be used for determining the cure properties of both unsupported resins and resins supported on substrates subjected to various oscillatory deformations. 1.2 This test method is intended to provide a means for determining the cure behavior of supported and unsupported thermosetting resins over a range of temperatures by free vibration as well as resonant and nonresonant forced-vibration techniques, in accordance with Practice D 4065. Plots of modulus, tan delta, and damping index as a function of time/temperature are indicative of the thermal advancement or cure characteristics of a resin. 1.3 This test method is valid for a wide range of frequencies, typically from 0.01 to 100 Hz. However, it is strongly recommended that low-frequency test conditions, generally below 1.5 Hz, be utilized as they generally will result in more definitive cure-behavior information. 1.4 This test method is intended for resin/substrate composites that have an uncured effective elastic modulus in shear greater than 0.5 MPa. 1.5 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. 1.6 Due to possible instrumentation compliance, especially in the compressive mode, the data generated may indicate relative and not necessarily absolute property values. 1.7 Test data obtained by this test method are relevant and appropriate for use in engi......

Differential scanning calorimetry provides a rapid test method for determining changes in specific heat capacity in a homogeneous material or domain. The glass transition is manifested as a step change in specific heat capacity. For amorphous and semi-crystalline materials the determination of the glass transition temperature may lead to important information about their thermal history, processing conditions, stability of phases, and progress of chemical reactions. This test method is useful for research, quality control, and specification acceptance.1.1 This test method covers the assignment of the glass transition temperatures (Tg) of materials using differential scanning calorimetry. 1.2 This test method is applicable to amorphous materials, including thermosets or semicrystaline materials containing amorphous regions, that are stable and do not undergo decomposition or sublimation in the glass transition region. 1.3 The normal operating temperature range is from –120 to 500°C. The temperature range may be extended, depending upon the instrumentation used. 1.4 Computer or electronic-based instruments, techniques, or data treatment equivalent to this test method may also be used.

General Utility: It is useful to verify catalyst levels in a resin blend or a polyurethane system. This practice is suitable for research, quality control, specification testing, and process control. Limitations: Several of the measured parameters are subjective. Therefore, operator-to-operator variability and lab-to-lab variability can be much higher than that of a single operator. The variability of this practice is dependent on the consistency of mixing of the reactants. The estimation of precision in this practice is based on typical formulations for rigid and flexible foams. Formulations with faster reaction times will likely have greater variability, particularly cream time (initiation time). Formulations with slower reaction times will likely have greater variability in the measurement of free rise time. It is possible that low-level (ppm, ppb) ingredient contamination will not be detectable using this practice. Confirmation of such contamination will potentially require large-scale (~ 20 litres) tests and is out of the scope of this practice.1.1 This practice covers the determination of cream time (initiation time), top of cup time, free rise time, free rise height, string gel time (pull time), tack free time, settle back, and free rise density of polyurethane foam formulations using a cup foam test. 1.2 Typical definitions, terms, and techniques are described; including procedures for mixing and transferring samples to the foaming container; and data gathering and evaluation. However, agreement between the customer and the testing laboratory for all these items must be obtained prior to use. 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.

Compression Molding8212;In compression molding, the difference between the dimensions of a mold and of the molded article produced therein from a given material vary according to the design and operation of the mold. It is probable that shrinkage will approach a minimum where design and operation are such that a maximum of material is forced solidly into the mold cavity or some part of it, or where the molded article is hardened to a maximum while still under pressure, particularly by cooling. In contrast, shrinkages are higher where the charge must flow in the mold cavity but does not receive and transmit enough pressure to be forced firmly into all its recesses, or where the molded article is not fully hardened when discharged. The plasticity of the material used affects shrinkage insofar as it affects the retention and compression of the charge. Injection Molding8212;In injection molding, as in compression molding, the differences between the dimensions of the mold and of the molded article produced therein from a given material vary according to the design and operation of the mold. The differences vary with the type and size of molding machine, the thickness of molded sections, the degree and direction of flow or movement of material in the mold, the size of the nozzle, sprue, runner, and gate, the cycle on which the machine is operated, the temperature of the mold, and the length of time that follow-up pressure is maintained. As in the case of compression molding, shrinkages will approach a minimum where design and operation are such that a maximum of material is forced solidly into the mold cavity and where the molded article is hardened to a maximum while still under pressure as a result of the use of a runner, sprue, and nozzle of proper size, along with proper dwell. As in compression molding, shrinkages are higher where the charge must flow in the mold cavity but does not receive and transmit enough pressure to be forced firmly into all of the recesses of the mold. The plasticity of the material used affects shrinkage indirectly, in that the more readily plasticized material will require a lower molding temperature. Transfer Molding8212;In transfer molding, as in compression or injection molding, the difference between the dimensions of the mold and of the molded article produced therein from a given material vary according to the design and operation of the mold. It is affected by the size and temperature of the pot or cylinder and the pressure on it, as well as on mold temperature and molding cycle. Direction of flow is not as important a factor. Materials Standards8212;Always refer to material standards for special treatment prior to molding, molding conditions and special handling of the test specimens after molding. In the event the material standard is unavailable, contact the manufacturer for these recommendations. Utility8212;Measurement of batch-to-batch consistency in initial shrinkage from mold to molded dimensions is useful for evaluating the quality of thermosetting plastics. 1.1 This test method is intended to measure shrinkage from mold cavity to molded dimensions of thermosetting plastics when molded by compression, injection, or transfer under specified conditions. 1.2 This test method provides for the measurement of shrinkage of thermosetting plastics from their molds both initially (within 16 to 72 h of molding) and as they age (post–shrinkage at elevated temperatures). 1.3 This method will give comparable data based on standard specimens and can not predict absolute values in actual mol......

This test method can be used to obtain the ignition loss of a cured reinforced resin sample. This test method can also be used to examine the fiber architecture of pultruded structural shapes. If only glass fabric or filament is used as the reinforcement of an organic resin that is completely decomposed to volatile materials under the conditions of this test and the small amount of volatiles (water, residual solvent) that may be present is ignored, the ignition loss can be considered to be the resin content of the sample. This test method does not provide a measure of resin content for samples containing reinforcing materials that lose weight under the conditions of the test or containing resins or fillers that do not decompose to volatile materials released by ignition.1.1 This test method covers the determination of the ignition loss of cured reinforced resins. This ignition loss can be considered to be the resin content within the limitations of 4.2. 1.2 The values stated in SI units are to be regarded as the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This test method is useful for selecting coating powders of similar characteristics of melt flow under minimal shear. It is not recommended as an absolute measurement, but rather as a comparative measurement of samples on the same panel measured at the same time. 1.1 This test method specifies a method for determining the flow characteristics of a fused thermosetting coating powder down a plane inclined at a set angle to the horizontal. The test gives an indication of the degree of melt flow that may occur during the curing of the coating powder. This characteristic contributes to the coherence of the coating, to its surface appearance and to the degree of coverage over sharp edges (see Test Method D2967), however, it should not be used as the sole factor for judgment. The test acts as a useful method for checking for batch to batch variation in the behavior of a given coating powder. Correlation between the results from coating powders of differing composition is not to be expected. This method is unlikely to yield meaningful results with coating powders which have gel times of less than one minute at the test temperature (see Test Method D4217). Oven drafts, angle of inclination and pellet variations significantly affect results making inter-lab reproducibility somewhat difficult to correlate. 1.2 The values stated in SI units are to be regarded as the standard.
