purpose and scope this test method provides a quantitative procedure for the evaluation of the degree of antibacterial activity. assessment of antibacterial finishes on textile materials is determined by the degree of antibacterial activity intended in the use of such materials. if only bacteriostatic activity (inhibition of multiplication) is intended, a qualitative procedure which clearly demonstrates antibacterial activity as contrasted with lack of such activity by an untreated specimen may be acceptable. however, if bactericidal activity is intended or implied, quantitative evaluation is necessary. quantitative evaluation also provides a clearer picture for possible uses of such treated textile materials.
purpose and scope this test method is intended for evaluating the resistance of the color of textiles of all kinds except polyimide, in all forms, to the action of bleach baths containing hydrogen peroxide at concentrations commonly employed in textile processing.
purpose and scope this test method determines the concentration of hydrogen peroxide (h2o2) in aqueous solutions, particularly those used in textile bleaching.
purpose and scope this test method is intended for the assay of the bacterial amylases employed commercially for textile desizing. it is not applicable to products which contain betaamylase in addition to alpha-amylase
purpose and scope this test method is designed to evaluate the resistance to water spotting of dyed, printed or otherwise colored textile fabrics. whites can also exhibit color change, such as yellowing. the test method does not determine whether the discoloration is removable.
purpose and scope this test method is designed to measure the resistance to sea water of dyed, printed, or otherwise colored textile yarns and fabrics of all kinds. artificial sea water is used in this test because natural sea water is variable in composition, and is often difficult to obtain.
purpose and scope this test method is designed to measure the resistance to water of dyed, printed, or otherwise colored textile yarns and fabrics. distilled water or deionized water is used in this test method because natural (tap) water is variable in composition.
purpose and scope this test method is intended for determining the resistance of the color of textiles to the action of ozone in the atmosphere at room temperatures with relative humidities not exceeding 67%.
purpose and scope this test method provides procedures for measuring the whiteness and tint of textiles using formulas recommended by the cie (see 12.1). the method describes the procedures to be used and also the limitations and restrictions that apply.
purpose and scope this test method provides a means for determining the weather resistance of textile materials. the test options described below are applicable to fibers, yarns and fabrics and products made therefrom, including coated fabrics, whether natural, colored, finished or unfinished. test options included are: option a—direct exposure to natural light and weather option b—behind glass exposure to natural light and weather without direct wetting outdoor testing as described under this method must be performed to verify accelerated laboratory testing. it is up to interested parties to determine frequency and scope of outdoor testing. refer to aatcc test method (tm) 169, weather resistance of textiles: xenon lamp exposures, and tm186, weather resistance: uv light and moisture exposure), for information on the limitations of accelerated laboratory testing. this test method contains the following sections that assist in the use and implementation of the various options for determining the weather resistance of textiles.
