ASTM D4943 – Standard Test Method for Shrinkage Factors of Cohesive Soils by the Water Submersion Method Description: Significance and Use 5.1 The shrinkage limit can be used to evaluate the shrinkage potential, crack development potential, and swell potential of earthwork involving cohesive soils. 5.2 The shrinkage limit, along with the liquid limit and plastic limit of …
ASTM D4940 – Standard Test Method for Conductimetric Analysis of Water Soluble Ionic Contamination of Blast Cleaning Abrasives Description: Significance and Use 4.1 Abrasive media may contain ionic contamination naturally (for example, mineral abrasives), from manufacturing (quenching with contaminated water), transportation, storage or use (in the case of abrasive that is reused). Ionic contamination on the …
ASTM D4935 – Standard Test Method for Measuring the Electromagnetic Shielding Effectiveness of Planar Materials Description: Significance and Use 4.1 This test method applies to the measurement of SE of planar materials under normal incidence, far-field, plane-wave conditions (E and H tangential to the surface of the material). 4.2 The uncertainty of the measured SE values is …
ASTM D4929 – Standard Test Method for Determination of Organic Chloride Content in Crude Oil Description: Significance and Use 5.1 Organic chlorides do not occur naturally in crude oil. When present, they result from contamination in some manner, such as disposal of chlorinated solvent used in many dewaxing pipeline or other equipment operations. 5.1.1 Uncontaminated crude oil …
ASTM D4928 – Standard Test Method for Water in Crude Oils by Coulometric Karl Fischer Titration Description: Significance and Use 5.1 The accurate analysis of a crude oil sample to determine the water content is important in the refining, purchase, sale, or transfer of crude oils. Scope 1.1 This test method covers the determination of water with …
ASTM D4927 – Standard Test Methods for Elemental Analysis of Lubricant and Additive Components—Barium, Calcium, Phosphorus, Sulfur, and Zinc by Wavelength-Dispersive X-Ray Fluorescence Spectroscopy Description: Significance and Use 4.1 Some oils are formulated with organo-metallic additives which act as detergents, antioxidants, antiwear agents, and so forth. Some of these additives contain one or more of these …
ASTM D4921 – Standard Test Method for Foaming Tendencies of Engine Coolants at Room Temperature Description: Significance and Use 4.1 The test method will generally identify coolants that have a tendency to foam excessively at room temperature. Note 1: In use, the foaming tendency of a coolant solution may be increased by service aging or contamination. Scope …
ASTM D4919 – Standard Guide for Testing of Hazardous Materials (Dangerous Goods) Packagings Description: Significance and Use 4.1 The UN performance tests are based on the degree of hazard presented by the proposed hazardous material(s) to be packaged. 4.2 Substances and articles which are hazardous are assigned to a specific packing group as defined in 3.8.1 and may be …
ASTM D4898 – Standard Test Method for Insoluble Contamination of Hydraulic Fluids by Gravimetric Analysis Description: Significance and Use 5.1 This test method indicates and measures the amount of insoluble contamination of hydraulic fluids. Minimizing the levels of insoluble contamination of hydraulic fluids is essential for the satisfactory performance and long life of the equipment. Insoluble …
ASTM D4897- Standard Specification for Asphalt-Coated Glass-Fiber Venting Base Sheet Used in Roofing Description: Abstract This specification covers the manufacture and requirements of Type II heavy-duty asphalt-impregnated and coated glass-fiber venting base sheet with mineral surfacing on the top side and coarse mineral granules on the bottom side for use as the first ply of …
