ASTM D6147-97 (Reapproved 2020) defines rigorous test methods for determining the decrease in counterforce (force decay or stress relaxation) exerted by a test specimen of vulcanized rubber or thermoplastic elastomer when compressed at a constant deformation. This property is essential…

ASTM D6146-97 (Reapproved 2018) provides a comprehensive framework for developing monitoring programs targeting the primary aquatic plant nutrients: nitrogen and phosphorus. Following the structure of Guide D5851, this standard provides specific guidance for watersheds aiming to assess both natural and…

Soil erosion and resulting sedimentation is the major cause of nonpoint source pollution that threatens water resources. ASTM D6145-97 (Reapproved 2018) provides a comprehensive guide for developing and implementing monitoring projects directed toward sediment in watersheds. It recognizes the need…

📏 Scope and Detection Limits This standard test method, designated D6143-23, covers the determination of the iron content of bisphenol A (4,4′-Isopropylidenediphenol). It is specifically designed for quantifying iron concentrations within a validated range of 0.1 mg/kg to 10 mg…

α-Methylstyrene (AMS) is a vital monomer in the production of specialty polymers and resins. Ensuring its purity and managing trace impurities is critical for production quality and downstream processing. ASTM D6144-22 provides a standardized capillary gas chromatographic method for this…

📐 Test Method Scope and Summary ASTM D6142-21 provides a standardized procedure for determining known impurities in high-purity phenol using capillary gas chromatography (GC). The method is specifically intended for analyzing phenol of 99.9 % or greater purity and has…

ASTM D6141−18 (Reapproved 2022) provides a standardized guide for the preliminary screening of the clay component within Geosynthetic Clay Liners (GCLs) for chemical compatibility with site-specific or synthetic liquids. This short-term screening protocol uses index tests and flux measurements to…

📐 Test Method Overview and Scope This test method covers the determination of the degree of aerobic aquatic biodegradation of fully formulated lubricants or their components on exposure to an inoculum under controlled laboratory conditions. It is an ultimate biodegradation…

📐 Terminology and Specimen Conditioning According to ASTM D6140‑22, asphalt retention is defined as the volume of asphalt cement retained by paving fabrics per unit area after submersion. The test requires specimens to be conditioned in a controlled atmosphere. The…

ASTM D6138-23, known as the Emcor Test, standardizes the evaluation of corrosion-preventive properties in lubricating greases under dynamic wet conditions. It is essential for greases used in ball bearings exposed to water contamination. 📐 Scope and Key Definitions According to…

🔬 Scope and Purpose of D6136/D6136M ASTM D6136/D6136M-15 (Reapproved 2021) covers the determination of the relative saturating capacity of unsaturated (dry) felt papers used in roofing. This standard defines the rigorous vacuum method procedure for calculating the Kerosine Number, which…

📚 Scope and Significance This test method, D6137‑97 (Reapproved 2018), under the jurisdiction of ASTM Committee D33, evaluates the sulfuric acid resistance at elevated temperatures of polymer linings on carbon steel substrates for flue gas desulfurization (FGD) systems. The values stated…
