ASTM D3663 – Standard Test Method for Surface Area of Catalysts and Catalyst Carriers Description: Abstract This test method establishes the standard procedure for determining the surface areas of catalyst and catalyst carriers that have Type II or IV nitrogen adsorption isotherms, and specified minimum area. A volumetric measuring system is used to obtain at …
ASTM D3661 – Test Method for Staple Length of Man-Made Fibers Average and Distribution (Single-Fiber Length Machine Method) (Withdrawn 1994) Description:
ASTM D3645 – Standard Test Methods for Beryllium in Water Description: Significance and Use 4.1 These test methods are significant because the concentration of beryllium in water must be measured accurately in order to evaluate potential health and environmental effects. Scope 1.1 These test methods cover the determination of dissolved and total recoverable beryllium in most waters …
ASTM D3643 – Standard Test Method for Acid Number of Certain Alkali-Soluble Resins Description: Significance and Use 4.1 This test method is not appropriate for alkali-soluble resins whose acid functionality is due to incorporated anhydrides. Variations in manufacture, storage, and possible contamination of anhydride functional resins may cause partial hydrolysis, or esterification, which will invalidate data …
ASTM D3641 – Standard Practice for Injection Molding Test Specimens of Thermoplastic Molding and Extrusion Materials Description: Significance and Use 5.1 It is well known that plastic test specimens molded under different conditions can have significantly different properties. This practice is designed to minimize those differences by establishing operating protocols without being unnecessarily restrictive. 5.2 Always refer …
ASTM D3638 – Standard Test Method for Comparative Tracking Index of Electrical Insulating Materials Description: Significance and Use 5.1 Electrical equipment can fail as a result of electrical tracking of insulating material that is exposed to various contaminating environments and surface conditions. This method is an accelerated test which at relatively low test voltages, provides a …
ASTM D3634 – Standard Test Method for Trace Chloride Ion in Engine Coolants Description: Significance and Use 4.1 This test method permits the determination of very low levels of chloride ion in engine coolants containing the common corrosion inhibitor, mercaptobenzothiazole, or related mercaptans, which would normally interfere with the titration by also forming insoluble silver salts …
ASTM D3632- Standard Test Method for Accelerated Aging of Adhesive Joints by the Oxygen-Pressure Method Description: Significance and Use 5.1 This test method is useful to the adhesive manufacturer in research and development or in manufacturing control. The results are also used for specification acceptance or as a guide in adhesive selection. 5.2 The provisions for testing …
ASTM D3616 – Standard Test Method for Rubber—Determination of Gel, Swelling Index, and Dilute Solution Viscosity Description: Significance and Use 4.1 These tests are particularly useful for quality control in the production of synthetic rubbers. 4.2 Percent gel is a measure of the amount of insoluble rubber present in the chosen solvent. Gel may be introduced intentionally …
ASTM D3612 – Standard Test Method for Analysis of Gases Dissolved in Electrical Insulating Oil by Gas Chromatography Description: Significance and Use 5.1 Oil and oil-immersed electrical insulation materials may decompose under the influence of thermal and electrical stresses, and in doing so, generate gaseous decomposition products of varying composition which dissolve in the oil. The …
