1.1 本说明书涵盖通过各种方法生产的整体式甲基丙烯酸酯片材。对于本说明书，甲基丙烯酸酯片材应由聚合的丙烯酸单体组成，其中至少80%应为甲基丙烯酸甲酯。 附注1: 本规范旨在巩固已停产Fed的铸造甲基丙烯酸酯塑料片材部分的要求。规格。L-P-391D，已终止质量标准 D702 铸造甲基丙烯酸酯塑料片、棒、管和形状，以及已停产的规格 D1547 、挤出丙烯酸塑料片材。 1.2 本说明书旨在涵盖用于通用应用的丙烯酸板。对于特殊应用，请参考适当的使用标准。 1.3 以下安全危害警告仅适用于试验方法部分，章节 8 本说明书: 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.4 丙烯酸板经常用于极其清晰、无光学失真和无任何外来颗粒物质的应用中。只要仔细控制以消除对这些性能的不利影响，再研磨材料就适合使用。当这些性能受到不利影响时，不适合在B-1和B-2型板材中使用回收材料。A型不可能使用回收或再研磨材料-1和A-2材料，因为片材直接由单体生产 附注2: 本标准和ISO 7823-1涉及相同的主题，但技术内容不同。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers monolithic methacrylate sheets produced by various processes. For this specification, methacrylate sheet shall be composed of polymerized acrylic monomers of which at least 80 % shall be methyl methacrylate. Note 1: This specification is intended to consolidate the requirements of the Cast Methacrylate Plastic Sheets portion of discontinued Fed. Spec. L-P-391D, discontinued Specification D702 . Cast Methacrylate Plastic Sheets, Rods, Tubes and Shapes, and discontinued Specification D1547 , Extruded Acrylic Plastic Sheet. 1.2 This specification is intended to cover acrylic sheet for general-purpose applications. For specialty applications consult the appropriate use standards. 1.3 The following safety hazards caveat pertains only to the test methods portion, Section 8 , 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 Acrylic sheet is used frequently in applications in which extreme clarity, lack of optical distortion and absence of any foreign particulate matter are of primary significance. Reground material is suitable for use as long as careful control is used to eliminate adverse effects on these properties. The use of recycled material in type B-1 and B-2 sheet, is not suitable for use when these properties are adversely affected. The use of recycled or reground material is not possible for type A-1 and A-2 materials since the sheet is produced directly from monomer Note 2: This standard and ISO 7823-1 address the same subject matter, but differ in technical content. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
