ASTM D1439 – Standard Test Methods for Sodium Carboxymethylcellulose Description: Significance and Use 5.1 Moisture analysis (along with purity) is used to calculate the amount of active polymer in the material and must be considered when determining the amount of sodium carboxymethylcellulose to use in various formulations. Scope 1.1 These test methods cover the testing of sodium …
ASTM D1435 – Standard Practice for Outdoor Weathering of Plastics Description: Significance and Use 4.1 Tests conducted in accordance with this practice are used to evaluate the stability of plastic materials when they are exposed outdoors. The relative durability of plastics in outdoor use can be very different depending on the location of the exposure because …
ASTM D1434 – Standard Test Method for Determining Gas Permeability Characteristics of Plastic Film and Sheeting Description: Significance and Use 5.1 These measurements give semiquantitative estimates for the gas transmission of single pure gases through film and sheeting. Correlation of measured values with any given use, such as packaged contents protection, must be determined by experience. …
ASTM D143 – Standard Test Methods for Small Clear Specimens of Timber Description: Significance and Use 4.1 These test methods cover tests on small clear specimens of wood that are made to provide the following: 4.1.1 Data for comparing the mechanical properties of various species, 4.1.2 Data for the establishment of correct strength functions, which in conjunction with …
ASTM D1429 – Standard Test Methods for Specific Gravity of Water and Brine (Withdrawn 2022) Description: Significance and Use 4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid’s characteristics compared to a standard, usually water, at a specified temperature. This …
ASTM D1425 – Standard Test Method for Evenness of Textile Strands Using Capacitance Testing Equipment Description: Significance and Use 6.1 This test method for the determination of evenness of textile strands is used extensively for acceptance testing of commercial shipments of filament or spun staple yarn, comber laps, roving, sliver, or tops. 6.2 Values of strand evenness …
ASTM D1424 – Standard Test Method for Tearing Strength of Fabrics by Falling-Pendulum (Elmendorf-Type) Apparatus Description: Significance and Use 5.1 This test method for the determination of tearing strength by the falling pendulum type apparatus is used in the trade for the acceptance testing of commercial shipments of fabrics, but caution is advised since technicians may …
ASTM D1423 – Standard Test Method for Twist in Yarns by Direct-Counting Description: Significance and Use 5.1 Test Method D1423 for testing twist in yarns by direct-counting is considered satisfactory for acceptance testing of commercial shipments because current estimates of between-laboratory precision are acceptable and the method has been used extensively in the trade for acceptance testing. 5.1.1 If …
ASTM D1417 – Standard Test Methods for Rubber Latices—Synthetic Description: Abstract This standard covers the test methods for synthetic rubber lattices ABR, BR, CR, IIR, NBR, NCR, NIR, PBR, PSBR, SBR, SCR, SIR, synthetic rubber lattices with substituted carboxylic acid groups on the polymer chain, and reinforced synthetic rubber lattices. Covered tests include the procedure …
ASTM D1415 – Standard Test Method for Rubber Property—International Hardness Description: Significance and Use 4.1 The International Hardness test is based on measurement of the penetration of a rigid ball into the rubber specimen under specified conditions. The measured penetration is converted into IRHD, the scale of degrees being so chosen that 0 represents a material …
