1、Designation: F 2440 04An American National StandardStandard Specification forIndoor Wall/Feature Padding1This standard is issued under the fixed designation F 2440; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last r
2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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 included.The i
3、ntended 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.NOTE 2There is no

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 the user of th

Classification4.1 Classify padding in accordance with the specific appli-cation.Type 1: Permanently
7、 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 shall be subj
8、ect 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 and in Table
9、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 SpecificationF 1292.6.2.2 The maximum gmaxvalues for the padding shall notexceed 200 and the HIC shall not exceed 1000 as listed inT
10、able 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 reconditionedpadding shall
11、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 becoming separa
12、ted 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 specification i
