1.1本规范涵盖高中和大学水平使用的竞赛摔跤垫。所有垫子结构均包括在内，但包在缝合盖中的毡芯垫子除外。本标准的预期用途是鉴定建筑设计。 笔记 1-截至本规范发布之日，已知结构为:( 1. )带有聚氯乙烯（PVC）或聚氯乙烯共聚物涂层或两者的闭孔泡沫芯，它们是垫子的组成部分；( 2. )闭孔泡沫芯，附带织物盖；( 3. )泡沫芯，开放式- 或封闭在缝好的松盖中的封闭单元，以及( 4. )模制开孔PVC泡沫塑料，一个表面有致密的表皮，是垫子的一个组成部分。 笔记 2-没有已知的ISO等同于本标准。 1.2本规范涵盖两种主要摔跤风格中使用的垫子:美国大学或高中摔跤和国际自由式摔跤。 1.3以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 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和健康实践，并确定监管限制的适用性。 具体危害说明见注释6。 ====意义和用途====== 垫子的构造应确保在制造商保修的条件下，在整个垫子区域内产生表1中列出的值。 垫子的特殊要求应以采购协议为准。 特殊要求不得减少本标准中列出的任何基本要求。 垫子的施工和检查应采用良好的制造规范。

1.1 This specification covers competition wrestling mats used at the high school and college levels. All mat constructions are included, except felt-core mats enclosed in sewn covers. The intended use of this standard is for the qualification of construction designs. Note 1—The known constructions, as of the issuance of this specification are: ( 1 ) closed-cell foam cores with polyvinyl chloride (PVC) or PVC copolymer coatings, or both, which are integral parts of the mat; ( 2 ) closed-cell foam cores with attached fabric cover; ( 3 ) foam cores, either open- or closed-cell enclosed in sewn, loose covers, and ( 4 ) molded open-cell PVC foam with a dense skin on one surface which is an integral part of the mat. Note 2—There is no known ISO equivalent to this standard. 1.2 This specification covers mats used in the two major styles of wrestling: U.S. collegiate or high school, and international free style. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. See Note 6 for specific hazards statements. ====== Significance And Use ====== The mats shall be constructed to yield the values listed in Table 1 throughout the mat area under the conditions of the manufacturer's warranty. Special requirements for the mats shall be subject to purchase agreements. Special requirements shall never reduce any of the basic requirements listed in this standard. Good manufacturing practices shall be used in the construction and inspection of the mats.
