1.1 本规范涵盖了玻璃纤维增强热固性聚酯、乙烯基酯或其他合格热固性树脂层压板的成分、厚度、制造程序和物理性能要求，包括RTP耐腐蚀罐、管道和设备的结构材料。本规范仅限于通过接触成型制造。 注1: 本规范涵盖的层压板是在接触成型RTP罐、管道和其他设备的制造过程中制造的。 注2: 目前还没有与该标准等效的ISO。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的国际单位制数值是从英寸磅单位转换而来的，仅供参考。 1.3 以下安全隐患警告仅适用于本规范第8节测试方法部分: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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 composition, thickness, fabricating procedures, and physical property requirements for glass fiber reinforced thermoset polyester, vinyl ester, or other qualified thermosetting resin laminates comprising the materials of construction for RTP corrosion-resistant tanks, piping, and equipment. This specification is limited to fabrication by contact molding. Note 1: The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment. Note 2: There is no known ISO equivalent to this standard. 1.2 The values stated in inch-pound units are to be regarded as standard. The SI values given in parentheses are conversions from inch-pound units and are for information only. 1.3 The following safety hazards caveat pertains only to the test method 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 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.
