1.1 The purpose of this classification system is to provide a method of adequately identifying PMMA materials using a system consistent with that of Classification System D 4000. It further provides a means for specifying these materials by the use of a simple line callout designation.1.2 This classification system covers poly(methyl methacrylate) molding and extrusion compounds. These compounds are polymers based on methyl methacrylate, and at least 70 % of the polymer shall be polymerized from methyl methacrylate.1.3 The properties in this classification system are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specific applications. These shall be described by using the suffixes as given in Section 5.1.4 Acrylic molding and extrusion compounds are used frequently in applications where extreme clarity and the ability to retain that clarity and color under severe weathering and other environmental exposures are of primary significance. While the test specimen properties of this document may be used to evaluate nonvirgin materials, the user should take precautions to ensure that parts made from these materials meet the desired end-use requirements. Accordingly, this specification allows for the use of those acrylic plastic materials that can be recycled, reconstituted, and regrounded provided the following:1.4.1 The requirements as stated in this specification are met,1.4.2 The material has not been modified in any way to alter its conformance to food contact regulations or similar requirements, and1.4.3 The requirements of the particular end-use application are met.1.5 This classification system and subsequent line callout (specification) are not intended for the selection of materials, but only as a means to call out plastic materials to be used for the manufacture of parts. The selection of these materials is to be made by personnel with expertise in the plastics field in which the environment, inherent properties of the materials, performance of the parts, part design, manufacturing process, and economics are considered. Note 18212;This classification system is similar to ISO 8257-1:1987 in title only. The technical content is significantly different.1.6 The values stated in SI units are to be regarded as the standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM D1975-95(2006) 塑料注模开口桶抗环境应力断裂的标准试验方法

These procedures provide an indication of the environmental stress-crack resistance of injection molded open head pails, covers, and components from a selected group or lot. Provided the thermal history of each container is constant, this test method may be used for determining the applicability of various plastic resins and mold designs for injection molding of open head pails and covers. The environmental stress-crack that occurs is indicative of what results when a container is exposed to agents such as soaps, organics, or any surface active solutions while under environmental conditions of stress. Environmental stress-cracking is the mechanism of chemical attack that is highly dependent upon the test reagent, resin, container molding history, exposure temperature, applied stress, and other factors. The combination of these factors may result in eventual stress-crack failure. Procedure A minimizes the potential for test variability by providing the user with rigidly defined test conditions. This test method may be used for production quality control of injection molded open head containers. Procedure B allows the user to select and evaluate extreme individual elements or the interaction of several test levels on container performance. These conditions are established based on laboratory experience and available knowledge of the distribution environment. This test method may be used for identifying critical stresses which could aid in container design or help in minimizing the occurrence of these stresses during distribution. This test method is intended only as a pass/fail procedure in accordance with the userrsquo;specification, or as agreed upon between the user and the supplier. It is not intended as a predictor or indicator of field performance regarding time to failure.1.1 This test method provides procedures for an indication of the environmental stress crack resistance of plastic injection molded open head pails, covers, and components as a summation of the effects of container design, resin, manufacturing conditions, field performance, and other factors.1.2 This test method may be used to evaluate a container''s resistance to mechanical failure by cracking when in the presence of chemical and physical stresses.1.3 Two procedures are provided as follows:1.3.1 Procedure A, Specified Stress-Crack Resistance Test Method This procedure is particularly useful for quality control since the conditions of the test are specified.1.3.2 Procedure B, User Selected Stress-Crack Resistance Test Method This procedure allows individual selection of test levels and is particularly useful as a design and development tool.1.4 These procedures are not designed to test the ability of the cover gasketing material or closure to retain the test reagent. Loss or leakage of the reagent through these openings does not constitute container failure. However, this may indicate an internal pressure loss that might affect test results.1.5 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.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. Specific warning statements are given in 6.2, 10.2.3, 10.2.4, 10.2.6, and 10.2.8.
