ASTM Standards Interpretation
📐 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…
ASTM D2157-24, under the jurisdiction of Committee D02 on Petroleum Products and Lubricants, provides a definitive standardized procedure for evaluating the effect of air supply on the smoke density of flue gases from burning distillate fuels. This test method is…
📌 Scope and Significance of D2152-23 ASTM D2152-23, an American National Standard, defines a test method for evaluating the adequacy of fusion in extruded rigid poly(vinyl chloride) (PVC) pipe and molded fittings. The core procedure involves immersing a prepared specimen…
🔥 Test Method Overview: Assessing Autoignition This standard, designated ASTM D2155-18 (Reapproved 2024), establishes a definitive procedure for assessing the fire resistance of hydraulic fluids used in aircraft applications. The core objective is the determination of the autoignition temperature (AIT)…
📜 Scope and Significance of ASTM D215-91 ASTM D215-91 (Reapproved 2002) provides a comprehensive standard practice for the chemical analysis of traditional white linseed oil paints. Issued under the jurisdiction of ASTM Committee D01 on Paint and Related Coatings, this…
