📐 Scope and Application (D2168-10) ASTM D2168-10 covers the essential practices for calibrating mechanical devices used in the laboratory compaction of soils and soil-aggregates. It is strictly applicable for equipment used in conjunction with standards such as Test Methods D698…
📜 Standard Overview and Significance The ASTM D2165-94 (Reapproved 2012) standard provides a definitive framework for assessing the pH of aqueous extracts derived from wool and similar animal fibers. This quantitative value serves as a direct indicator of the residual…
📐 Scope and Applicability of D2166 Standard D2166/D2166M-24 covers the determination of the unconfined compressive strength of cohesive soil in the intact, remolded, or reconstituted condition through strain-controlled application of the axial load. This test method provides an approximate value…
📐 Scope and Applicability for In-Place Density Testing ASTM D2167 – 15, formally the Standard Test Method for Density and Unit Weight of Soil in Place by the Rubber Balloon Method, establishes the procedure for determining the in-place density and…
ASTM D2164-83 defines methods for testing structural insulating roof deck, a laminated composite serving as finished ceiling, structural deck, and thermal insulation. Tests measure deflection and strength with the finished (ceiling) face in tension. Results are reported in inch-pound units,…
🏷️ Scope and Fundamental Principles of D2162-21 ASTM D2162-21 defines the standard practice for the basic calibration of master viscometers and viscosity oil standards. These primary references constitute the highest level of the metrological traceability chain for kinematic viscosity measurements.…
ASTM D2163-23™ is the definitive standard for the quantitative determination of individual hydrocarbons in liquefied petroleum (LP) gases and propane/propene mixtures using gas chromatography. It serves as a critical tool for producers, pipeline operators, and testing laboratories to verify product…
🔬 Test Principle and Scope (ASTM D2158-21) ASTM D2158-21 establishes a standardized gravimetric procedure for determining the presence of heavy, extraneous residues in Liquefied Petroleum (LP) Gases. The method specifically targets materials that do not volatilize at ambient temperatures, formally…
🔬 Scope and Applicability ASTM D2161-20 provides the standardized conversion tables and equations for translating kinematic viscosity, measured in mm²/s (equivalent to centistokes, cSt), into legacy Saybolt Universal Seconds (SUS) and Saybolt Furol Seconds (SFS). The kinematic viscosity scale used…
📐 Scope and Application ASTM D2156-09 (Reapproved 2024) is a standard test method for evaluating smoke density in flue gases from burning distillate fuels. It is primarily intended for use with home heating equipment burning kerosine or heating oils. This…
