【国外标准】 Standard Practice for Accelerated Heat Aging for Floor Covering Adhesives

4.1 The final appearance of an installed floor depends upon several factors. These include but are not limited to the manufacture of the flooring material, the preparation of the subfloor and the skill of the installer. This practice is used to measure the ability of the adhesive to retain its original physical properties and adhesion following exposure to heat simulating a long service life at reasonable and expected temperatures.4.2 In selecting or developing a carpet or resilient flooring or other adhesive, it is critical to have knowledge regarding how well the adhesive will bond to the substrate and to the flooring material.4.3 Heat accelerated aging is necessary to establish the stability of the adhesive as it concerns storage/shelf life including viscosity (Test Method D1084) while remaining in an unopen container for prolonged periods.4.4 In determining the applicable physical properties for shear strength (Test Method D6004) and peel strength (Test Method D6862) for the determination of dimensional stability of the assembled flooring material.1.1 This practice describes a procedure to determine the physical properties and longevity of the floor covering adhesive and the effect on it following accelerated heat aging.1.2 This practice assists in determining compatibility of adhesive and respective floor covering for long term use.1.3 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.1.4 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.1.5 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.
