ASTM F2440-2004(2010) Standard Specification for Indoor Wall Feature Padding《室内墙壁 部件填充物标准规范》.pdf

1、Designation: F2440 04 (Reapproved 2010)An American National StandardStandard Specification forIndoor Wall/Feature Padding1This standard is issued under the fixed designation F2440; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th

2、e year of last revision. 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 wall padding and padding forother indoor structures.All padding constructions are

3、included.The intended use of this specification is for the qualification ofconstruction designs and comparison of products.NOTE 1This specification was developed due to the numerous designsin existence and the need to provide a method to determine if a wall padmeets a minimum level of protection.NOT

4、E 2There is no equivalent ISO standard.1.2 The values as stated in SI units are to be regarded as thestandard. The values in parentheses are given for informationonly.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of

5、the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use. See 7.1 for specifichazards statement.2.

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 coatingpolyvinyl chloride (PVC) or PVC copoly-mer, or both, or other suitable polymeric materials.4. Classification4.1 Classify padding in accordance with the specific appli-cation.Type 1

7、: Permanently attached Type 2: RemovableGrade A: Coated Grade B: Covered or encased5. Significance and Use5.1 The padding shall be constructed to yield the valueslisted in Table 1 throughout the impact area under the condi-tions of the manufacturers warranty.5.2 Special requirements for the padding

8、shall be subject topurchase 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 padding.6. Performance Requirements6.1 The requirements listed in this section

9、and in Table 1 areminimal for new and reconditioned padding.6.2 Shock Absorption:6.2.1 Determine the shock absorption properties of thepadding in accordance with instrumentation of SpecificationF1292.6.2.2 The maximum gmaxvalues for the padding shall notexceed 200 and the HIC shall not exceed 1000 a

10、s listed inTable 1. Lower values for gmaxand HIC indicate bettershock-absorbing values.NOTE 3Under the specified test conditions (that is, missile size,impact velocity, and so forth), lower gmaxvalues indicate better shock-absorbing properties.6.3 ThicknessThe thickness of the new or reconditionedpa

11、dding shall be sufficient to provide the shock-absorptionproperties listed in Table 1.7. General Requirements7.1 Wall padding is normally produced in sections that areassembled prior to use. The padding shall be installed such thatthese sections are fastened securely together to prevent themfrom bec

12、oming separated during use. (WarningAreas ofpadding missing coating or covering are considered healthhazards.)8. Dimensions, Mass, and Permissible Variations8.1 Padding should be used on walls and other facilityfeatures in or around the playing area that an athlete mightcontact during play.1This spe

16、ation9.1 The test specimens shall be representative of the fin-ished padding, a section cut from a finished pad, or a smallersample made at the same time and with the same constructionand materials as the pad.10. Test Methods10.1 Conduct the tests at a temperature of 23 6 2C (73.4 63.6F) and 50 6 5

17、% relative humidity, unless otherwisespecified.10.2 The shock absorption properties of the mats shall bedetermined using Specification F1292 with the followingconditions:10.2.1 Laboratory and field test.10.2.2 Impact velocities of 498 6 22 cm/s (215 6 9 in./s).4 ft drop height.NOTE 4Impact velocity,

18、 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 normallyeliminate greater amounts of frictio
