1.1 本规范涵盖了挤出、压模和注塑聚甲醛（POM）板材、板材、棒材和管状棒材（不包括管道和配件）的材料、尺寸、工艺和性能的要求和测试方法。 1.2 本规范中包含的特性是所涵盖组合物所需的特性。部分 4. 提出了一种分类系统，用于定义对专业应用程序重要的特定特性的要求。 1.3 本规范允许使用回收塑料。 1.4 以英寸-磅为单位的数值应视为所有性能和尺寸表中的标准值。出于参考目的，国际单位制仅包含在表S-POM和表1中。 1.5 以下预防性警告仅适用于试验方法部分，第 11 ，本规范: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 注1: 没有已知的ISO等效于本标准。 1.6 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》中确立的国际公认标准化原则制定的。

1.1 This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded, compression molded and injection molded polyoxymethylene (POM) sheet, plate, rod, and tubular bar shapes, excluding pipe and fittings. 1.2 The properties included in this specification are those required for the compositions covered. Section 4 presents a classification system for defining requirements for particular characteristics important to specialized applications. 1.3 This specification allows for the use of recycled plastics. 1.4 The values stated in inch-pound units are to be regarded as the standard in all property and dimensional tables. For reference purposes, SI units are included in Table S-POM and Table 1 only. 1.5 The following precautionary caveat pertains only to the test method portions, Section 11 , 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. Note 1: There is no known ISO equivalent to this standard. 1.6 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.
