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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See Note 6 for specific hazards statements. 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. ====== Significance And Use ====== 5.1 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. 5.2 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. 5.3 Good manufacturing practices shall be used in the construction and inspection of the mats.
