In the case of field evaluation, five tests shall beperformed, and may be required, in the area of interest or ov

Sample Conditioning10.1 Field samples shall be under the intended use condi-tion, although loose debris shall be removed prio

Other laboratory samplesshall be preconditioned at 65 6 2 % relative humidity and

Samples evaluated atconditions other than that of the laboratory must be testedimmediately after a minimum of 4 h conditioning.10.3 Condition test blocks in the laboratory for at least 4 hbefore use at 65 % relative humidity and 21 6 1C (70 6 2F).11.

The blockscan be secured using double-stick carpet tape. Position the testframe such that it can be pulle

23、d with, against, or across thefabric machine direction. Center the 9.072-kg (20-lb) testweight on the test frame and attach the pull cable hook.11.3 Pull the loaded frame 45.7 cm (18.0 in.) in eachprimary surface direction (with, across, against, across, for3Available from UpJohn Corp., CPR Div., 55

The test rate is not critical,but the time to travel each 45.7 cm (18-in.) side must bebetween 8 and 12 s.11.4 Note any deviations in rate, how smo

25、othly the testframe could be pulled, and any deviation from a square pattern.11.5 Carefully remove and store the test blocks for weigh-ing.11.6 Repeat the test procedure as required in 9.1 and 9.2.11.7 Record the general condition of the surface; whethermatted, clean, worn, etc. Temperature, humidit

Discussion14.1 With regard to precision, the reproducibility is esti-mated to be 610 %.14.2 Potential sources of error or deviations are as follows;14.2.1 Variations in density, mat

30、erial, compressive strength,or cell properties of the friable test foam.14.2.2 Variations in path of friable test foam.14.2.3 Path deviationSince the weighted foam is notconstrained to move in a straight path as it is pulled in aprincipal direction, it will tend to drift somewhat in thedirection of

31、pile angle. The deviation of the abrasion patternleft on the surface from a square reflects the directionality ofthe surface.15.
