Standard Guide for Determining or Confirming Care Instructions for Apparel and Other Textile Consumer Products
SCOPE
1.1 This guide may be used to determine and confirm the appropriate care label instructions for apparel, piece goods, and other consumer textile products excluding textile floor coverings and upholstered fabrics.
1.2 This guide encompasses the following care procedures: home laundering, commercial laundering, professional drycleaning, and coin-operated drycleaning.
1.3 This guide includes provision for evaluating the complete consumer textile product and the product components.
1.4 This guide covers the performance characteristics as a result of refurbishing that are important in determining the acceptability of a textile product to the consumer.
1.5 This guide is appropriate for the evaluation of all garments and household textiles that are sold with permanently attached care labels.
1.5.1 This guide may also be used in connection with the evaluation of similar materials that do not have a care label.
