Standard Test Method for Extractable Matter in Textiles

Importancia y uso:

5.1 This test method can be used for acceptance testing of commercial shipments.

5.1.1 In case of a dispute arising from differences in reported test results using this test method for acceptance testing of commercial shipments, the purchaser and the supplier shall conduct comparative tests to determine if there is a statistical bias between the laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties shall take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question. Then the test specimens shall be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories shall be compared using appropriate statistical analysis and a probability level chosen by the two parties before the testing begins. If a bias is found, either its cause must be found and corrected, or the purchaser and supplier must agree to interpret future test results with consideration to the known bias.

5.2 This test method is used for the determination of the amounts of naturally present oily or waxy impurities that have not been completely removed from textiles made from animal fibers and for the determination of the amounts of oily or waxy finishing materials applied to raw materials or textiles during manufacture.

5.3 The test method can be used as a step in the determination of the commercial weight of fiber, yarn, and textile shipments.

5.4 The International Wool Textile Organization specifies the use of a halogenated hydrocarbon, dichloromethane, also called methylene chloride (CH₂Cl₂) instead of the solvent specified in this test method (IWTO-10-62(E)).

5.5 Extractables by mass loss is frequently used for fibers, yarns, and textiles which have a relatively large amount of extractable material to effect a significant mass change. This test can also be used in testing textile materials for forensic purposes.

5.6 Additional solvents which may be more appropriate for new materials and more sustainable procedures or equipment that use less solvent per specimen are detailed in AATCC TM 97.
