(Practice)Standard Practice for Evaluating Adhesive and the Effects of Plasticizer Found Within Polyvinyl Chloride-Backed Floor Coverings
Standard Practice for Evaluating Adhesive and the Effects of Plasticizer Found Within Polyvinyl Chloride-Backed Floor Coverings
SIGNIFICANCE AND USE
4.1 Plasticizer migration is detrimental to many adhesives, including hot melts, which could be possibly used in conjunction with PVC backed flooring materials, whether resilient or textile, broadloom, tile or plank. This practice can be used as an indicator to determine if plasticizers in the flooring material are compatible with proposed installation adhesive(s).
SCOPE
1.1 This standard will provide a qualitative means to determine the potential effects of plasticizers contained within polyvinyl chloride (PVC) floor covering materials on a specific adhesive.
1.2 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.
1.3 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.
1.4 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.
