ASTM D2260 – Standard Tables of Conversion Factors and Equivalent Yarn Numbers Measured in Various Numbering Systems Description: Scope 1.1 These tables include (1) a series of conversion factors required to convert the number of a yarn measured in a specific system to the equivalent number measured in various other systems (see Table 1), and (2) specific …
ASTM D226 – Standard Specification for Asphalt-Saturated Organic Felt Used in Roofing and Waterproofing Description: Abstract This specification covers asphalt-saturated organic felt used in roofing and waterproofing. Two types of asphalt-saturated felts are presented: type I – commonly called No. 15 asphalt felt, and type II – commonly called No. 30 asphalt felt. In the …
ASTM D2259 – Standard Test Method for Shrinkage of Yarns Description: Significance and Use 5.1 Test Method D2259 for testing yarn for shrinkage in boiling water, saturated steam, dry heat, or solvents is considered satisfactory for acceptance testing of commercial shipments of yarn because the test method has been used extensively in the trade for that purpose. 5.1.1 If …
ASTM D2257 – Standard Test Method for Extractable Matter in Textiles Description: Significance and Use 5.1 This test method may 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 should …
ASTM D2256 – Standard Test Method for Tensile Properties of Yarns by the Single-Strand Method Description: Significance and Use 5.1 Acceptance Testing—Option A1 of Test Method D2256 is considered satisfactory for acceptance testing of commercial shipments because the test method has been used extensively in the trade for acceptance testing. However, this statement is not applicable to knot …
ASTM D2248 – Standard Practice for Detergent Resistance of Organic Finishes Description: Significance and Use 3.1 Any effects such as color change, blistering. loss of adhesion, softening, or embrittlement are observed and noted. Scope 1.1 This practice covers the determination of the resistance to failure, in an accelerated manner, of organic finishes when immersed in a detergent …
ASTM D2247 – Standard Practice for Testing Water Resistance of Coatings in 100 % Relative Humidity Description: Significance and Use 4.1 Water can cause the degradation of coatings, so knowledge of how a coating resists water is helpful for assessing how it will perform in actual service. Failure in tests at 100 % relative humidity may be caused …
ASTM D2244 – Standard Practice for Calculation of Color Tolerances and Color Differences from Instrumentally Measured Color Coordinates Description: Significance and Use 5.1 The original CIE color scales based on tristimulus values X, Y, Z and chromaticity coordinates x, y are not uniform visually. Each subsequent color scale based on CIE values has had weighting factors applied to provide some …
ASTM D2243 – Standard Test Method for Freeze-Thaw Resistance of Water-Borne Coatings Description: Significance and Use 4.1 When water-borne coatings are shipped during cold weather, they may experience cycles of freezing and thawing. Cycles of freezing and thawing cause more damage to water-borne coatings than when the coatings are subjected to steady freezing. Scope 1.1 This test …
ASTM D2240 – Standard Test Method for Rubber Property—Durometer Hardness Description: Significance and Use 4.1 This test method is based on the penetration of a specific type of indentor when forced into the material under specified conditions. The indentation hardness is inversely related to the penetration and is dependent on the elastic modulus and viscoelastic behavior …
