1、Designation: F 1081 97 (Reapproved 2003)e1An American National StandardStandard Specification forCompetition Wrestling Mats1This standard is issued under the fixed designation F 1081; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,

2、 the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.e1NOTEPrecision and Bias section was added and warning notes in Sections 8.3 and 11.2 were updated in September 2003

3、.1. Scope1.1 This specification covers competition wrestling matsused at the high school and college levels. All mat construc-tions are included, except felt-core mats enclosed in sewncovers. The intended use of this standard is for the qualificationof construction designs.NOTE 1The known constructi

4、ons, as of the issuance of this specifi-cation are: (1) closed-cell foam cores with polyvinyl chloride (PVC) orPVC copolymer coatings, or both, 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, loos

5、e 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 equivalent ISO 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

6、 values as stated in SI units are to be regarded as thestandard. The values in parentheses are given for informationonly.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-p

7、riate safety and health practices and determine the applica-bility of regulatory limitations prior to use. See Note 5 andNote 7 for specific hazards statements.2.

Significance and Use5.1 The mats shall be constructed to yield the values listedin Table 1 throughout the mat area under the conditions of themanufacturers warranty.5.2 Special requirements for the mats shall be subject topu

12、rchase agreements. Special requirements shall never reduceany of the basic requirements listed in this standard.5.3 Good manufacturing practices shall be used in theconstruction and inspection of the mats.1This specification is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Faci

Physical Properties6.1 Tensile StrengthThe minimum tensile strength of thecover and f

16、oam system shall be 8.8 N/mm (50 lbf/in.).7. Performance Requirements7.1 The requirements listed in this section and in Table 1 areminimal for new and reconditioned mats.7.2 Shock Absorption:7.2.1 Determine the shock absorption properties of the matsin accordance with Procedure A of Test Method F 35

17、5.7.2.2 The maximum gmaxvalues for the mats shall be aslisted in Table 1.NOTE 3Under the specified test conditions (that is, missile size,impact velocity, etc.), lower gmaxvalues indicate better shock-absorbingproperties.7.2.3 Replace or recondition the mats when the gmaxin thevisibly deteriorated a

18、reas exceed the values listed in Table 1.7.3 Thickness:7.3.1 The thickness 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 1.7.3.2 Replace or recondition the mats when the thickness inthe

19、visibly deteriorated areas falls below the values listed inTable 1, or fails 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 testin

20、g the mat.7.4 The surfaces shall be smooth and free of step-offs ordepression greater than 1.6 mm (116 in.).8. General Requirements8.1 Competition wrestling mats normally are produced insections which are assembled prior to use. These sections shallbe fastened securely together, using an adhesive co

21、ated tape orother means, to prevent their becoming separated during use.8.2 A mat shall have a maximum of 20 sections, unlessotherwise specified.NOTE 5Twenty sections are needed for a 12.8 by 12.8-m (42 by 42-ft)molded open-cell PVC mat. Typically, other types of mats would have upto three sections.

22、8.3 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 6Mats should be cleaned and sanitized daily, or after each use,as recommended by the manufac

23、turer.9. Dimensions9.1 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 High SchoolAssociations.9.2 The length and width dimensions of the mats

24、 shall be asgiven in the appropriate rule book.10. Workmanship, Finish, and Appearance10.1 The mats shall be made using manufacturing proce-dures which ensure that the bonds between the strips orsections, or coating, or all three, are complete and secure.NOTE 7The finish shall be uniform in color fo

25、r each color usednormally with a semi-glossy finish for the coatings.10.2 On mats with sewn covers, the cover may be loose(that is, not adhered to the foam), but should have no wrinklesor seams exposed that will injure the wrestlers or cause them totrip.10.3 Sectional mats shall have sections that f

26、it togethersecurely, so they do not separate in use, with maximumstep-offs between sections of 1.6 mm (116 in.) for new mats.11. Specimen Preparation11.1 The test specimens may be a finished mat, a section cutfrom a finished mat, or a smaller sample made at the same timeand with the same constructio

27、n and materials as the mat.11.2 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 solvents.)NOTE 8Curing is affected by environmental factors.11.2.1

28、The length of the “curing time will vary and shouldbe determined by consultation with the mat manufacturer.11.2.2 This “curing time is in addition to the environmen-tal conditioning prior to testing.12. Test Methods12.1 Conduct the tests at a temperature of 23 6 2C (73.4 63.6F) and 50 6 5 % relative

29、 humidity, unless otherwisespecified.12.2 The shock absorption properties of the mats shall bedetermined using Test Method F 355 with the followingconditions:12.2.1 Procedure A, cylindrical missile.12.2.2 Impact velocities of 432 6 22 cm/s (170 6 9 in./s).NOTE 9Impact velocity, rather than a drop he

30、ight, 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 normallyeliminate greater amounts of friction.12.3 Measure the thi
