1.1 This test method covers the determination of the amount of moisture present in ordinary commercial and industrial samples of wool in all forms except grease wool, using the oven-drying technique.
1.2 Formulas for calculating the moisture content (asreceived basis) and moisture regain (oven-dried basis) are given. It is always important to use the correct term which corresponds to the basis used in the calculation (see 12.2.1). NOTE 1—The determination of moisture content for textile materials in general is covered in Test Methods D2654, and an optimal method for determining the moisture in wool by distillation with toluene is covered in Test Method D2462. A method for sampling wool for the determination of moisture in wool is covered in Practice D2525. The oven-drying method has been adapted for cotton in Test Method D2495.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
