2、evision, the 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 establishes minimum requirementsfor adhesives used for the installation of tuf
3、ted or wovenbroadloom carpet, within a climate controlled structure, whenadhered directly, and permanently, to a structurally sound andrecommended substrate.1.2 This specification will provide the means to determineadhesive bonding variation as a result of different carpetbacking systems and their u
4、sage classifications based on thetraffic conditions they are subjected to.1.3 This specification is not applicable to specialty adhe-sives such as those necessary for PVC and Non-PVC backedcarpet tile and broadloom where the backing would be consid-ered homogenous in nature.1.4 The values stated in
5、inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It i
6、s theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Place 1qt (1L) of the adhesivein a wide-mouth glass or stainless steel container and sealtightly. Use for all the tests with the exception of freeze-thawstability, Practice D7149, and storage l
31、ife, Practice D1337. Forthe initial test only, to provide samples for testing these twoproperties, divide the second 1qt (1L) equally and use halffor the freeze-thaw stability and half for storage life.
