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 …
ASTM D2354 – Standard Test Method for Minimum Film Formation Temperature (MFFT) of Emulsion Vehicles Description: Significance and Use 3.1 The satisfactory film integrity of emulsion coatings requires that as the aqueous phase evaporates the resinous portion of the vehicle coalesces into a continuous film. Low temperature impairs the fluidity of the resin particle and thereby …
ASTM D2197 – Standard Test Method for Adhesion of Organic Coatings by Scrape Adhesion Description: Significance and Use 4.1 Coatings to perform satisfactorily must adhere to the substrates on which they are applied. This test method has been found useful in differentiating the degree of adhesion of coatings to substrates. It is most useful in providing …
ASTM D2062 – Standard Test Methods for Operability of Zippers Description: Significance and Use 4.1 The significance of specific tests is discussed in the appropriate sections. 4.2 These test methods are considered satisfactory for acceptance testing of commercial shipments of zippers because the methods have been used extensively in the trade for this purpose, even though current …
ASTM D2061 – Standard Test Methods for Strength Tests for Zippers Description: Significance and Use 4.1 The usefulness of a zipper in service can be evaluated by these tests. No one test determines the suitability of a zipper for a specific end use. Since the tests are inter-related more than one may be needed for a …
ASTM D1929 – Standard Test Method for Determining Ignition Temperature of Plastics Description: Significance and Use 4.1 Tests made under conditions herein prescribed can be of considerable value in comparing the relative ignition characteristics of different materials. Values obtained represent the lowest ambient air temperature that will cause ignition of the material under the conditions of …
ASTM D1960 – Standard Test Method for Loss on Heating of Drying Oils (Withdrawn 2003) Description: 1.1 This test method covers the determination of moisture and any other material that is volatile under the conditions of the test. It is applicable to all natural drying oils.Note 1-For solutions of drying oils in volatile organic solvents …
ASTM D1957 – Standard Test Method for Hydroxyl Value of Fatty Oils and Acids (Withdrawn 2007) Description: Scope 1.1 This test method covers the determination of the hydroxyl content of castor oil, dehydrated castor oil, and their derivatives. This test method may also be used for other fatty products such as fatty alcohols, mono- and …
ASTM D1903 – Standard Practice for Determining the Coefficient of Thermal Expansion of Electrical Insulating Liquids of Petroleum Origin, and Askarels Description: Significance and Use 4.1 Knowledge of the coefficient of thermal expansion of a liquid is essential to compute the required size of a container to accommodate a volume of liquid over the full temperature …
ASTM D1894 – Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting (Withdrawn 2023) Description: Significance and Use 4.1 Measurements of frictional properties may be made on a film or sheeting specimen when sliding over itself or over another substance. The coefficients of friction are related to the slip properties …
