United States16.2.1 Determine the shock absorption properties of the padding in accordance with instrumentation of Specification F1292.6.2.2 The
15、maximum gmax values for the padding shall not exceed 200 and the HIC shall not exceed 1000 as listed in Table 1.Lower values for gmax and HIC indicate better shock-absorbing values.NOTE 3Under the specified test conditions (that is, missile size, impact velocity, and so forth), lower gmax values ind
16、icate better shock-absorbingproperties.6.3 ThicknessThe thickness of the new or reconditioned padding shall be sufficient to provide the shock-absorption propertieslisted in Table 1.7. General Requirements7.1 Wall padding is normally produced in sections that are assembled prior to use. The padding
17、shall be installed such that thesesections are fastened securely together to prevent them from becoming separated during use. (WarningAreas of padding missingcoating or covering are considered health hazards.)8. Dimensions, Mass, and Permissible Variations8.1 Padding should be used on walls and othe
18、r facility features in or around the playing area that an athlete might contact duringplay.8.1 The Where wall padding is used in an indoor facility, the length and width dimensions of the mats mats, as well as theirproximity to the floor, shall be appropriate to provide protection for that area. the
19、 intended use of the facility. Padding shall beinstalled no more than 4 in. from the floor.9. Specimen Preparation9.1 The test specimens shall be representative of the finished padding, a section cut from a finished pad, or a smaller samplemade at the same time and with the same construction and mat
20、erials as the pad.10. Test Methods10.1 Conduct the tests at a temperature of 23 6 2C (73.4 6 3.6F) and 50 6 5 % relative humidity, unless otherwise specified.10.2 The shock absorption properties of the mats shall be determined using Specification F1292 with the following conditions:10.2.1 Laboratory
21、 and field test.10.2.2 Impact velocities of 489 6 22 cm/s (192.5 6 9 in./s). 4 ft drop height.NOTE 4Impact velocity, rather than a drop height, is specified to eliminate the problem of friction on the guide rails of the missile. Minor amountsof friction can be overcome by simply increasing the drop
22、height. Cleaning or lubricating, or both, the guide rods and bearing will normally eliminategreater amounts of friction.TABLE 1 Performance and Physical Property Values for WallPaddingAProperty Section Test Method Newgmax 10.2 SpecificationF1292at 489 22 cm/s(192.5 9 in./s), max200Thickness, mm (in.
