Full Description
This method contains four accelerated tests for determining the colourfastness to washing of textile fabrics, threads and yarns. Each test is designed to produce in a single treatment the colour loss to be expected after five average home or commercial washings under one of four commonly used sets of conditions.
The four tests contained in this method are:
Test No. 1 -- For textile materials that are expected to withstand repeated hand washing, or equivalent gentle machine washing, at low temperatures (approximately 400C).
Test No. 2 -- For textile materials that are expected to withstand repeated machine washing at moderate temperatures (approximately 500C) in the home or in a commerical laundry.
Test No. 3 -- For textile materials that are expected to withstand repeated machine washing at high temperatures (approximately 700C) without bleach, in the home or in a commerical laundry.
Test No. 4 -- For textile materials that are expected to withstand repeated machine washing at high temperatures (approximately 700C) in the presence of hypochlorite bleach, in the home or in a commerical laundry.
This method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate health and safety practices in conjunction with any existing applicable regulatory requirements prior to its use.
