ASTM D2238 – Standard Test Methods for Absorbance of Polyethylene Due to Methyl Groups at 1378 cm−1 Description: Significance and Use 4.1 When interpreted with the aid of appropriate calibration data, either test method is acceptable for use to compare the total methyl contents of polyethylenes made by similar processes. Data on infrared absorption at certain …
ASTM D2236 – Standard Method of Test for Dynamic Mechanical Properties of Plastics by Means of a Torsional Pendulum
ASTM D2229 – Standard Test Method for Adhesion Between Steel Tire Cords and Rubber (Withdrawn 2023) Description: Significance and Use 5.1 This test method is considered satisfactory for the acceptance testing of commercial shipments of steel tire cord because current estimates of between-laboratory precision for single materials are considered acceptable and the method has been used …
ASTM D2228 – Standard Test Method for Rubber Property—Relative Abrasion Resistance by Pico Abrader Method Description: Significance and Use 4.1 This test method may be used to estimate the relative abrasion resistance of subject materials as described in 1.1. No correlation between this accelerated test and service performance is given or implied, due, in part, to the …
ASTM D2222 – Standard Test Method for Methanol Extract of Vinyl Chloride Resins Description: Significance and Use 5.1 The methanol extract test is most commonly employed with paste- or dispersion-type vinyl resins intended for organosol or plastisol applications. The test result is a quantitative measure of the methanol-soluble, nonvolatile, essentially nonpolymeric content of the virgin, unmodified …
ASTM D2216 – Standard Test Methods for Laboratory Determination of Water (Moisture) Content of Soil and Rock by Mass Description: Significance and Use 5.1 For many materials, the water content is one of the most significant properties used in establishing a correlation between soil behavior and its index properties. 5.2 The water content of a material is …
ASTM D2212 – Standard Test Method for Slit Tear Resistance of Leather Description: Significance and Use 4.1 This test method is designed to measure the load required to tear leather at a slit cut perpendicular to its surface. Tanners and leather buyers have found that it gives an indication of the resistance of the cross-sectional thickness …
ASTM D2211 – Standard Test Method for Elongation of Leather Description: Significance and Use 4.1 The elongation measurement may be made at any designated load and is expressed as a percentage of the original distance between the jaws or between bench marks of the unstretched specimen. The speed of the machine is important. Speeds under or …
ASTM D2209 – Standard Test Method for Tensile Strength of Leather Description: Significance and Use 5.1 The tensile strength test gives a reliable indication of the quality of the leather. Improperly lubricated and partially degraded leathers give low values for tensile strength. The orientation of the specimen in relation to the backbone and the location of …
ASTM D2208 – Standard Test Method for Breaking Strength of Leather by the Grab Method Description: Significance and Use 5.1 The measurement of the strength of leather is often necessary in order to determine its suitability for its intended application. This test method is recommended for use on light, soft leathers, narrow strap, welt, lace and …
