1. Scope
1.1 This specification covers competition wrestling mats used at the high school and college levels. All mat construc- tions are included, except felt-core mats enclosed in sewn covers. The intended use ofthis standard is for the qualification of construction designs. N OTE 1—The known constructions, as of the issuance of this specifi- cation 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. N OTE 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 inter- national 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 appro- priate safety, health, and environmental practices and deter- mine the applicability of regulatory limitations prior to use. See Note 6 for specific hazards statements. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
5. 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.
6. Performance Requirements
6.1 The requirements listed in this section and in Table 1 are minimal for new and reconditioned mats. 6.2 Shock Absorption: 6.2.1 Determine the shock absorption properties of the mats in accordance with Procedure A of Test Method F355. 6.2.2 The maximum g max values for the mats shall be as listed in Table 1. N OTE 3—Under the specified test conditions (that is, missile size, impact velocity, etc.), lower g max values indicate better shock-absorbing properties. 6.2.3 Replace or recondition the mats when the g max in the visibly deteriorated areas exceed the values listed in Table 1. 6.3 Thickness: 6.3.1 The thickness ofthe new or reconditioned mat shall be sufficient to provide the shock-absorption properties listed in Table 1, but never less than the minimum values in Table 1. 6.3.2 Replace or recondition the mats when the thickness in the visibly deteriorated areas falls below the values listed in Table 1, or fails to provide the necessary shock absorption. It is strongly recommended that the mat owner test the mat peri- odically to determine when to replace or recondition a mat. N OTE 4—Contact the manufacturer if help is needed in testing the mat. 6.4 The surfaces shall be smooth and free of step-offs or depression greater than 1 ⁄ 16 in. (1.6 mm).
7. General Requirements
7.1 Competition wrestling mats normally are produced in sections which are assembled prior to use. These sections shall be fastened securely together, using an adhesive coated tape or other means, to prevent their becoming separated during use. 7.3 Mats of the coating/foam construction shall not be used if any areas of the coating are missing. (Warning—Areas of mats of coating/foam construction having missing coating are considered health hazards.) N OTE 5—Mats should be cleaned and sanitized daily, or after each use, as recommended by the manufacturer.
