📐 Scope and Significance This standard practice, designated ASTM D2962-23, provides a standardized methodology for calculating the volume-temperature correction for liquid coal-tar pitches. Because different pitches expand or contract at varying rates directly related to their relative density, a uniform…
📜 Test Method Overview and Significance ASTM D2967‑24 provides a standardized procedure to evaluate the corner coverage of powder coatings. This test method specifically measures the ratio of the coating thickness on sharp 90° corners to the thickness on adjacent…
ASTM D2961/D2961M-19 specifies a standard practice for the rapid, single-stage determination of total moisture in coal crushed to a 2.36 mm (No. 8 Sieve) topsize. This method is explicitly intended for coals with a total moisture content of less than…
📐 Scope and Principle of the Test Method This standard, ASTM D2959-95, covers the determination of ethylene oxide (EO) in polyethoxylated nonionic surfactants. Its applicability extends to any compounds that form unstable 1,2-diiodides, including propylene oxide derivatives, glycols, and polyglycol…
📋 Scope and Summary ASTM D2960 outlines a controlled laundering test using naturally soiled fabrics in household appliances to compare the cleaning and whitening performance of home laundering products or procedures. The test is conducted on a paired comparison basis,…
This article provides an overview of ASTM D2950/D2950M-22, which outlines a standard test method for determining the density of asphalt mixtures in place using nuclear methods. The procedure involves gamma radiation attenuation through either the backscatter or direct transmission technique.…
📐 Specimen Geometry and Preparation ASTM D2951-00 provides a definitive method for evaluating the thermal stress-cracking susceptibility of Type III and IV polyethylene plastics. The test specimens are rectangular strips cut from a compression-molded sheet prepared in accordance with Practice…
📐 Scope and Significance ASTM D2949 – 24 specifies the requirements for 3.25-inch Outside Diameter (OD) Poly(Vinyl Chloride) (PVC) plastic drain, waste, and vent (DWV) pipe and fittings. This standard covers material requirements, dimensions and tolerances, deflection load resistance, crush…
ASTM D295-12 establishes standard test methods for evaluating varnished cotton fabrics and varnished cotton fabric tapes used as electrical insulation. Recognized by the U.S. Department of Defense, this standard is directly applicable to both straight-cut and bias-cut materials and serves…
ASTM D2946-01 (Reapproved 2018) establishes the official terminology for asbestos and asbestos–cement products. Managed by ASTM Committee C17 on Fiber-Reinforced Cement Products, this standard is fundamental for ensuring consistent communication regarding material identification, test methods, and product specifications across the…
