ASTM D1938 – Standard Test Method for Tear-Propagation Resistance (Trouser Tear) of Plastic Film and Thin Sheeting by a Single-Tear Method Description: Significance and Use 5.1 This test method is of value in rating the tear-propagation resistance of various plastic films and thin sheeting of comparable thickness. For highly extensible film or sheeting the deformation energy …
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ASTM D1925 – Test Method for Yellowness Index of Plastics (Withdrawn 1995)
ASTM D1922 – Standard Test Method for Propagation Tear Resistance of Plastic Film and Thin Sheeting by Pendulum Method Description: Significance and Use 4.1 This test method is of value in ranking relative tearing resistance of various plastic films and thin sheeting of comparable thickness. Experience has shown the test to have its best reliability on …
ASTM D1921 – Standard Test Methods for Particle Size (Sieve Analysis) of Plastic Materials Description: Significance and Use 4.1 These test methods are used to determine particle size distribution and therefore are useful for determining lot-to-lot uniformity. 4.2 The particle sizes of plastic materials affect the handling characteristics and sometimes will affect the processing characteristics of some …
ASTM D1907 – Standard Test Method for Linear Density of Yarn (Yarn Number) by the Skein Method Description: Significance and Use 5.1 Test Method D1907/D1907M is considered satisfactory for acceptance testing of commercial shipments, since it has been used extensively in the trade for that purpose. 5.1.1 In case of dispute arising from differences in reported test results when …
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 D1895 – Standard Test Methods for Apparent Density, Bulk Factor, and Pourability of Plastic Materials Description: Significance and Use 4.1 These test methods provide useful indexes of performance of plastic materials such as powders and granules with respect to their handling in packaging and fabrication. 4.2 Apparent density is a measure of the fluffiness of a …
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 …
ASTM D189 – Standard Test Method for Conradson Carbon Residue of Petroleum Products Description: Significance and Use 5.1 The carbon residue value of burner fuel serves as a rough approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. Similarly, provided alkyl nitrates are absent (or if present, provided the …
