36、ted in Table 1.7. Carpet Inventory7.1 To control the variability of the carpeting used withinthe ASTM test methods, a central source3for carpeting hasbeen established by ASTM Committee F11 on Vacuum Clean-ers. It is the responsibility of the central source for carpeting tomaintain an adequate supply
37、 for each carpet type for testing.7.2 In order to maintain an adequate supply of carpet types,the central source for carpeting is to notify the F11.21.01 carpetstandardization task group chairman when the central source3supply is reduced to fifty (50) panels of a given carpet type.The F11.21.01 task
38、 group chairman will then contact the F11membership to determine the overall inventory outside thecentral source and instruct the central source to re-order thecarpeting, if necessary. This reorder is subject to task group,subcommittee, and main committee approval.8. Keywords8.1 carpets; padding; va
