📋 Scope and Significance This test method, designated D1913−00 (Reapproved 2023), provides a qualitative evaluation of the surface repellency to water of garment-type leathers. It is not applicable to wet blue. The values stated in inch-pound units are standard. This…

📋 Overview and Scope ASTM D1907/D1907M-12 (2018) is a standard test method for determining the linear density of yarn (yarn number) using the skein method. It applies to all types of yarn in package form, with limitations on stretch and…

📐 Scope and Significance ASTM D1909-13 provides standardized tables for commercial moisture regains (CMR) and commercial allowances (CA) used for textile fibers. These values are primarily intended for determining commercial weight during buying and selling, calculating yarn linear density, and…

📐 Overview and Significance This test method, designated D1901-10 (Reapproved 2020), covers the measurement of the relative evaporation time of halogenated organic solvents and their admixtures. It is applicable under standard conditions without excessive drafts or high-velocity air currents. The…

ASTM D1903‑08 (Reapproved 2017) provides a standardized practice for determining the average coefficient of thermal expansion for electrical insulating liquids of petroleum origin and askarels containing PCBs. This property is critical for the reliable design and operation of electrical apparatus such…

ASTM D1896/D1896M-10 (Reapproved 2017) establishes a comprehensive practice for the transfer molding of test specimens from thermosetting molding materials. This method is particularly effective for compounds exhibiting intermediate viscosity non-Newtonian flow, bridging the gap between compression and injection molding techniques.…

ASTM D 1898 – 68 (Reapproved 1989), the Standard Practice for Sampling of Plastics, delivers the fundamental principles for constructing practical and statistically sound sampling plans. Its core mission, as explicitly stated in Section 1.1, is to guide purchasers of…

🔬 Significance and Application of D1900-20 ASTM D1900-20, “Standard Practice for Carbon Black—Sampling Bulk Shipments,” provides a critical framework for obtaining representative samples from bulk carriers. The standard specifically applies to three-compartment hopper rail cars and compartmented bulk hopper trailers.…

🧪 Test Overview and Scope The ASTM D1894-24 standard provides the definitive methodology for determining the static and kinetic coefficients of friction (COF) of plastic film and sheeting. The test method covers the frictional © 2026 TNLab — This article…

ASTM D1895-24 provides standardized procedures for determining the apparent density, bulk factor, and pourability of plastic materials ranging from fine powders and granules to large flakes and cut fibers. These properties serve as critical indexes of performance for packaging, handling,…

🧪 Scope and Principle of the Conradson Carbon Residue Test The Standard Test Method D189-24 specifies the procedure for determining the amount of carbon residue left after evaporation and pyrolysis of an oil. This residue, commonly referred to as “carbon…

The ASTM D1890-15 (Reapproved 2017) standard provides a test method for measuring beta particle radioactivity in water. It is designed for beta emitters with maximum energies above 0.1 MeV and activity levels above 0.02 Bq/mL (540 pCi/L) in homogeneous water…
