(Specification)Standard Performance Specification for Soft Window Covering Fabrics for Household Use
Standard Performance Specification for Soft Window Covering Fabrics for Household Use
ABSTRACT
This performance specification establishes the evaluation of specific performance characteristics of any washable or dry-cleanable soft window covering fabrics, whether lined or unlined, for household use. The characteristics to be evaluated prior to repeated refurbishing include, but are not limited to, seam strength and appearance, uniformity of shade (part to part), and size consistency (side to side and part to part). Consequently, the characteristics to be evaluated after repeated refurbishing include, but are not limited to, colorfastness, dimensional change, seam strength, appearance, and compatibility of components. Compatibility of dimensional change between drapery fabric and lining should be noted.
SIGNIFICANCE AND USE
4.1 This specification may be used to evaluate pertinent performance characteristics of washable and drycleanable soft window coverings, whether lined or unlined.
4.1.1 Soft window covering characteristics to be evaluated prior to repeated refurbishing include, but are not limited to, seam strength and appearance, uniformity of shade (part to part), and size consistency (side to side and part to part).
4.1.2 Soft window covering characteristics to be evaluated after repeated refurbishing include, but are not limited to, colorfastness, dimensional change, seam strength, appearance, and compatibility of components. Compatibility of dimensional change between drapery fabric and lining should be noted.
4.2 The specified home laundry machine settings do not reflect advances in cycle design or special features of washer and dryers which enhance the performance of these products. The standard washing and drying procedure reflects the minimum capabilities of current home laundering equipment used by consumers in accordance with care label instructions.
4.2.1 The reproducibility of the results of the test method specified in 9.2 depends on the use of procedures for automatic home laundering as specified on care labels.
4.3 The areas to be evaluated and the criteria assigned to these areas shall be set by mutual agreement between purchaser and supplier.
SCOPE
1.1 This specification covers the evaluation of specific performance characteristics of any washable or drycleanable soft window covering.
1.2 This specification is not a specification for washable or drycleanable soft window coverings but may be used by mutual agreement between the purchaser and the supplier to establish material specifications.
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 and health practices and determine the applicability of regulatory limitations prior to use.
