ASTM D1946 – Standard Practice for Analysis of Reformed Gas by Gas Chromatography Description: Significance and Use 4.1 The information about the chemical composition can be used to calculate physical properties of the gas, such as heating (calorific) value and relative density. Combustion characteristics, products of combustion, toxicity, and interchangeability with other fuel gases may also …
ASTM D1945 – Standard Test Method for Analysis of Natural Gas by Gas Chromatography Description: Significance and Use 4.1 This test method is of significance for providing data for calculating physical properties of the sample, such as heating value and relative density, or for monitoring the concentrations of one or more of the components in a …
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ASTM D1925 – Test Method for Yellowness Index of Plastics (Withdrawn 1995)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 …
