1、Designation: F1081 09An American National StandardStandard Specification forCompetition Wrestling Mats1This standard is issued under the fixed designation F1081; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi

2、sion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers competition wrestling matsused at the high school and college levels. All mat construc-tions are incl

3、uded, except felt-core mats enclosed in sewncovers. The intended use of this standard is for the qualificationof construction designs.NOTE 1The known constructions, as of the issuance of this specifi-cation are: (1) closed-cell foam cores with polyvinyl chloride (PVC) orPVC copolymer coatings, or bo

4、th, which are integral parts of the mat; (2)closed-cell foam cores with attached fabric cover; (3) foam cores, eitheropen- or closed-cell enclosed in sewn, loose covers, and (4) moldedopen-cell PVC foam with a dense skin on one surface which is an integralpart of the mat.NOTE 2There is no known ISO

5、equivalent to this standard.1.2 This specification covers mats used in the two majorstyles 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 regardedas standard. The values given in parentheses are mathematicalconversions

6、to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and d

7、etermine the applica-bility of regulatory limitations prior to use. See Note 6 forspecific hazards statements.2.

Performance Requirements6.1

16、 The requirements listed in this section and in Table 1 areminimal for new and reconditioned mats.6.2 Shock Absorption:6.2.1 Determine the shock absorption properties of the matsin accordance with Procedure A of Test Method F355.6.2.2 The maximum gmaxvalues for the mats shall be aslisted in Table 1.

17、NOTE 3Under the specified test conditions (that is, missile size,impact velocity, etc.), lower gmaxvalues indicate better shock-absorbingproperties.6.2.3 Replace or recondition the mats when the gmaxin thevisibly deteriorated areas exceed the values listed in Table 1.6.3 Thickness:6.3.1 The thicknes

18、s of the new or reconditioned mat shall besufficient to provide the shock-absorption properties listed inTable 1, but never less than the minimum values in Table 1.6.3.2 Replace or recondition the mats when the thickness inthe visibly deteriorated areas falls below the values listed inTable 1, or fa

19、ils to provide the necessary shock absorption. It isstrongly recommended that the mat owner test the mat peri-odically to determine when to replace or recondition a mat.NOTE 4Contact the manufacturer if help is needed in testing the mat.6.4 The surfaces shall be smooth and free of step-offs ordepres

20、sion greater than116 in. (1.6 mm).7. General Requirements7.1 Competition wrestling mats normally are produced insections which are assembled prior to use. These sections shallbe fastened securely together, using an adhesive coated tape orother means, to prevent their becoming separated during use.7.

21、2 A mat shall have a maximum of 20 sections, unlessotherwise specified.7.3 Mats of the coating/foam construction shall not be usedif any areas of the coating are missing. (WarningAreas ofmats of coating/foam construction having missing coating areconsidered health hazards.)NOTE 5Mats should be clean

22、ed and sanitized daily, or after each use,as recommended by the manufacturer.8. Dimensions8.1 The mats shall meet the requirements for minimaldimensions and markings given in the rules of the NationalCollegiate Athletic Association, the U.S. Wrestling Federation,and the National Federation of State

23、High SchoolAssociations.8.2 The length and width dimensions of the mats shall be asgiven in the appropriate rule book.9. Workmanship, Finish, and Appearance9.1 The mats shall be made using manufacturing procedureswhich ensure that the bonds between the strips or sections, orcoating, or all three, ar

24、e complete and secure.NOTE 6The finish shall be uniform in color for each color usednormally with a semi-glossy finish for the coatings.9.2 On mats with sewn covers, the cover may be loose (thatis, not adhered to the foam), but should have no wrinkles orseams exposed that will injure the wrestlers o

25、r cause them totrip.9.3 Sectional mats shall have sections that fit togethersecurely, so they do not separate in use, with maximumstep-offs between sections of116 in. (1.6 mm) for new mats.10. Specimen Preparation10.1 The test specimens may be a finished mat, a section cutfrom a finished mat, or a s

26、maller sample made at the same timeand with the same construction and materials as the mat.10.2 Coated mats must be aged to “cure the mats beforetesting. This is necessary to ensure the evaporation of solventsfrom the coating and foam core. (WarningUnreliable datawill result from mats containing sol

27、vents.)NOTE 7Curing is affected by environmental factors.10.2.1 The length of the “curing time will vary and shouldbe determined by consultation with the mat manufacturer.10.2.2 This “curing time is in addition to the environmen-tal conditioning prior to testing.11. Test Methods11.1 Conduct the test

28、s at a temperature of 73.4 6 3.6F (236 2C) and 50 6 5 % relative humidity, unless otherwisespecified.11.2 The shock absorption properties of the mats shall bedetermined using Test Method F355 with the following condi-tions:11.2.1 Procedure A, cylindrical missile.11.2.2 Impact velocities of 167 6 8.6

29、 in./s (423 6 22 cm/s).NOTE 8Impact velocity, rather than a drop height, is specified toeliminate the problem of friction on the guide rails of the missile. Minoramounts of friction can be overcome by simply increasing the drop height.Cleaning or lubricating, or both, the guide rods and bearing will

30、 normallyeliminate greater amounts of friction.11.3 Measure the thickness as outlined in SpecificationD1056, or as specified by agreement between the purchaserand the supplier.12. Product Marking12.1 Each mat shall have appropriate warning labels perma-nently attached to the performing surfaces.13.
