⚙️ Scope and Significance of the Unconfined Compressive Strength Test Standard test method D2938-95 (Reapproved 2002) establishes the apparatus, instrumentation, and procedures required to determine the unconfined compressive strength of intact rock core specimens. This method involves cutting a rock…

ASTM D2939-03 provides a comprehensive suite of standard test methods for evaluating emulsified bitumens intended for use as thick-film protective coatings. Developed under the jurisdiction of ASTM Committee D08 on Roofing and Waterproofing, these methods replace the previous standards D1010…

📐 Specimen Geometry and Types The D2936-20 standard rigorously defines the scope of acceptable test specimens. It specifically covers the determination of direct tensile strength for intact, isotropic cylindrical rock core specimens. The testing force must be applied normal to…

📐 Scope and Limitations The D2937-24 test method determines in-place density of soil near the surface by driving a thin-walled cylinder into the soil. This method is not recommended for organic or friable soils that may compress during sampling. Soils…

The ASTM D2930-03 standard defines a potentiometric titration method for quantifying free maleic acid in refined maleic anhydride. This technique is essential for assessing moisture contamination, as maleic anhydride readily hydrolyzes to maleic acid. The method is applicable for all…

📐 Scope and Terminology This standard, designated ASTM D2935-96 (Reapproved 2000), defines a test method for measuring the apparent density of industrial aromatic hydrocarbons. The result is expressed in pounds in air per U.S. gallon, using a hydrometer at a…

🔬 Scope and Significance of ASTM D2929-89 ASTM D2929-89 (Reapproved 2019) specifies a standard test method for the determination of sulfur content in cellulosic materials using X-ray fluorescence (XRF) spectrometry. This method provides a direct alternative to conventional wet chemical…

🎯 Scope and Significance of the Coke Sieve Analysis The ASTM D293/D293M −18 standard provides the definitive test method for determining the particle size distribution of coke. This method is essential for verifying that a coke product meets specific size…

This article provides an overview of ASTM D2924-24, the standard test method for evaluating the external pressure resistance of fiberglass pipes. It covers test specimen requirements, failure classification, and key properties measured during testing. 📐 Test Specimen and Conditioning Specimens…

The ASTM D2925-24 standard provides a definitive methodology for measuring the beam deflection of fiberglass pipe under full bore flow conditions. This test method, which measures deflection as a function of time over a simply supported span, is critical for…

🧪 Overview and Scope of D2923-13 ASTM D2923-13 measures the rigidity of polyolefin film and sheeting using two distinct procedures. The test method relies on a strain gauge attached to a beam which forces the film sample into a groove…

📖 Scope and Significance This test method, designated D2921 –98 (Reapproved 2024), covers simple qualitative field or laboratory tests for determining water repellency or the presence of chlorinated phenol preservative chemicals in wood products specified to be water repellent preservative…

These test methods detail the determination of the total or wet density of soil and soil-aggregate in place using nuclear gauges at shallow depths. The standard covers two primary configurations: the Backscatter Method, where the source and detectors remain on…

ASTM D2918-99 (Reapproved 2020) is a standardized method for evaluating the durability of adhesive joints under peel stress. It employs T-peel specimens subjected to constant stress in controlled environments, providing data on how stress and moisture affect adhesive performance over…

ASTM D2919-01 (Reapproved 2023) provides a standardized methodology for assessing the durability of adhesive lap-shear joints under constant stress while exposed to specific environmental conditions. This accelerated screening test is critical for predicting in-service performance of bonded assemblies, particularly where…

📐 Specification Scope and Referenced Documents ASTM D2916-09 (Reapproved 2023) is a standard specification covering isophorone (98 % grade), chemically known as 3,5,5-trimethyl-2-cyclohexene-1-one. This material is intended for use as a solvent in paint, varnish, lacquer, and related coating products.…

This specification covers the requirements for methyl isoamyl ketone (98 % grade) used primarily in paint, varnish, lacquer, and related coating products. Originally approved in 1970, the current edition (D2917 – 07 (Reapproved 2021)) provides standardized property limits and test…
