ASTM D4647 – Standard Test Methods for Identification and Classification of Dispersive Clay Soils by the Pinhole Test Description: Significance and Use 5.1 The pinhole test provides one method of identifying the dispersive characteristics of clay soils that are to be or have been used in earth construction. The piping failures of a number of homogeneous …
ASTM D4644 – Standard Test Method for Slake Durability of Shales and Other Similar Weak Rocks Description: Significance and Use 5.1 The test method is used to estimate qualitatively the durability of weak rocks through weakening and disintegration resulting from a standard two cycles of wetting and drying in the service environment. (1-7).3 5.2 This test method is …
ASTM D4643 – Standard Test Method for Determination of Water Content of Soil and Rock by Microwave Oven Heating Description: Significance and Use 5.1 The water content of a soil is used throughout geotechnical engineering practice both in the laboratory and in the field. The use of Test Method D2216 for water content determination can be time consuming …
ASTM D4641 – Standard Practice for Calculation of Pore Size Distributions of Catalysts and Catalyst Carriers from Nitrogen Desorption Isotherms Description: Significance and Use 5.1 Pore volume distribution curves obtained from nitrogen sorption isotherms provide one of the best means of characterizing the pore structure in porous catalysts, provided that the limitations of the method are …
ASTM D4637 – Standard Specification for EPDM Sheet Used in Single-Ply Roof Membrane Description: Abstract This specification covers flexible sheet made from ethylene-propylene-diene terpolymer (EPDM) intended for use in single-ply roofing membranes exposed to the weather. The rubber sheet may be non-reinforced (Type I), fabric or scrim internally reinforced (Type II), or fabric-backed (Type III) …
ASTM D4636 – Standard Test Method for Corrosiveness and Oxidation Stability of Hydraulic Oils, Aircraft Turbine Engine Lubricants, and Other Highly Refined Oils Description: Significance and Use 4.1 This test method simulates the environment encountered by fully formulated lubricating fluids in actual service and uses an accelerated oxidation rate to permit measurable results to be obtained …
ASTM D4632 – Standard Test Method for Grab Breaking Load and Elongation of Geotextiles Description: Significance and Use 5.1 The grab method is applicable whenever it is desired to determine the “effective strength” of the fabric in use, that is, the strength of the material in a specific width, together with the additional strength contributed by …
ASTM D4629 – Standard Test Method for Trace Nitrogen in Liquid Hydrocarbons by Syringe/Inlet Oxidative Combustion and Chemiluminescence Detection Description: Significance and Use 5.1 Some process catalysts used in petroleum and chemical refining may be poisoned when even trace amounts of nitrogenous materials are contained in the feedstocks. This test method can be used to determine …
ASTM D4628 – Standard Test Method for Analysis of Barium, Calcium, Magnesium, and Zinc in Unused Lubricating Oils by Atomic Absorption Spectrometry Description: Significance and Use 5.1 Some oils are formulated with metal-containing additives that act as detergents, antioxidants, antiwear agents, etc. Some of these additives contain one or more of these metals: barium, calcium, zinc, …
ASTM D4627 – Standard Test Method for Iron Chip Corrosion for Water–Miscible Metalworking Fluids Description: Significance and Use 5.1 The results obtained by this test are a useful guideline in determining the ability of water-miscible metalworking fluids to prevent or minimize rust under specific conditions. There is usually a relationship between the results of this test …
