(Specification)Standard Specification for Tufted and Woven Broadloom Carpet Adhesives Without Homogenous PVC or Non-PVC Backings
Standard Specification for Tufted and Woven Broadloom Carpet Adhesives Without Homogenous PVC or Non-PVC Backings
ABSTRACT
This specification establishes minimum requirements for adhesives used for the installation of tufted or woven broadloom carpet, within a climate controlled structure, when adhered directly, and permanently, to a structurally sound and recommended substrate. It provides the means to determine adhesive bonding variation as a result of different carpet backing systems and their usage classifications based on the traffic conditions they are subjected to. This specification also describes classification, standard conditioning, chemical composition, physical properties, performance requirements, sampling, certification, and packaging and package marking.
SCOPE
1.1 This specification establishes minimum requirements for adhesives used for the installation of tufted or woven broadloom carpet, within a climate controlled structure, when adhered directly, and permanently, to a structurally sound and recommended substrate.
1.2 This specification will provide the means to determine adhesive bonding variation as a result of different carpet backing systems and their usage classifications based on the traffic conditions they are subjected to.
1.3 This specification is not applicable to specialty adhesives such as those necessary for PVC and Non-PVC backed carpet tile and broadloom where the backing would be considered homogenous in nature.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
