Standard Test Method for Length and Length Distribution of Cotton Fibers (Array Method)
Abstract: 5.1 The array method provides objective measurements for determining the fiber length and length distribution in a sample of cotton. The results can be plotted to show the length-weight distribution of all the fibers in ... -
Standard Test Method for Polyurethane Raw Materials: Determination of APHA (Platinum-Cobalt) Color of Isocyanates
Abstract: 5.1 This test method can be used for research or for quality control to characterize isocyanates used in polyurethane products. 5.2 For toluene diisocyanate, results from this test method can relate to reactivity or ... -
Standard Test Method for Bond Strength of Electrical Insulating Varnishes by the Twisted-Coil Test
Abstract: 5.1 Values obtained by flexural test provides information about the bond strength of the particular varnish in combination with a particular type of magnet wire, when measured under conditions described in this test method. ... -
Standard Test Methods for Polyurethane Raw Materials: Determination of Gardner and APHA (Platinum-Cobalt) Color of Polyols
Abstract: 5.1 These test methods are suitable for quality control, as specification tests, and for research. Color is an important property of urethane products. -
Standard Test Method for Thermal Endurance of Varnished Fibrous, Film-Wrapped, or Film Insulated Magnet Wire
Abstract: 4.1 Individual varnishes behave differently when applied to the same fibrous, film-wrapped, or film insulated magnet wire when exposed to elevated temperatures. Likewise, a varnish does not always behave the same when ... -
Standard Test Methods of Polyurethane Raw Materials: Determination of the Polymerized Ethylene Oxide Content of Polyether Polyols
Abstract: 5.1 Measurements of EO content correlate to polyol reactivity (as related to primary hydroxyl content), linearity of foam rise, and hydrophilicity of the polyol and final product. -
