SIGNIFICANCE AND USE
This practice may be used to evaluate pertinent performance characteristics of machine washable or drycleanable bedcoverings.
The characteristics to be evaluated and the acceptance criteria assigned to these areas shall be set by mutual agreement between purchaser and supplier.
The significance and use of specific properties are discussed in the appropriate test methods and performance standards.
SCOPE
1.1 This practice may be used to evaluate specific characteristics of importance in the performance of bedcoverings and accessories (machine washable or drycleanable, woven and knit) including bedspreads, comforters, quilts, pillow-shams, dust ruffles, and blankets, hereinafter referred to collectively as bed-coverings.
1.2 This practice is not to be used to evaluate bedcoverings that are refurbished by handwashing.
1.3 This practice shall not be construed to be a standard of performance for bedcoverings.
1.4 This practice shall not be used to evaluate sheets.
1.5 This practice may be used by mutual agreement between purchaser and supplier to set purchasing specifications.
1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
