ASTM Standards Interpretation
📐 Specimen Types and Preparation The D2812-07 standard provides a method for determining non-lint content in cotton using the Shirley Analyzer. Cotton specimens can be in several forms, as outlined in the scope: (1) raw stock, which is cotton fiber…
⚗️ Purpose and Significance of Standard D281-12 The ASTM D281-12 (Reapproved 2021) standard provides a foundational method for determining the oil absorption of pigments using the spatula rub-out technique. The primary purpose of this test is to evaluate the vehicle…
📐 Scope and Key Definitions for D2810-24 This standard test method, designated D2810-24, provides a reproducible procedure for determining the pH of all types of finished leather. It explicitly does not apply to wet blue or wet white. The test…
🔬 Scope and Significance This standard test method, designated D2807-17a, covers the determination of chromic oxide (Cr₂O₃) in leathers that have been partially or completely tanned with chromium compounds. Samples analyzed by this procedure typically contain between 1 and 5…
🧪 Scope and Test Objective ASTM D2809-21 provides a standardized laboratory method for evaluating the cavitation corrosion and erosion-corrosion characteristics of aluminum automotive water pumps when exposed to aqueous engine coolants. The test is performed within a pressurized simulated cooling…
The ASTM D2804-22 standard outlines a gas chromatographic method for determining the purity of methyl ethyl ketone (MEK). This technique separates MEK from common impurities such as hydrocarbons, alcohols, acetone, di-sec-butyl ether, and ethyl acetate. The chromatographic results are normalized…
📐 Scope and Application Domain This test method, issued under the fixed designation D2805-11 (Reapproved 2023), covers the determination of the hiding power of air-dry coatings strictly through reflectometry, without requiring a material paint standard for comparison. It is specifically…
📐 Material Composition and Application Scope This article provides an overview of ASTM D2802–14, the Standard Specification for Ozone-Resistant Ethylene-Alkene Polymer Insulation for Wire and Cable. This specification governs a crosslinked rubber insulation compound designed for outstanding ozone resistance. The…
📋 Scope and Mechanism of Filiform Corrosion ASTM D2803-09 (Reapproved 2020) provides a standardized guide for evaluating the susceptibility of organic-coated metal substrates to filiform corrosion. Per the standard’s terminology, filiform corrosion is defined as a special type of under-film…
ASTM D280-01 (Reapproved 2023) specifies standardized test methods for determining hygroscopic moisture and other matter volatile under the test conditions in pigments. These methods are critical for quality control under the jurisdiction of ASTM Committee D01 on Paint and Related…
This standard test method, designated D 2800 – 92 (Reapproved 1998), provides a rapid procedure for converting animal and vegetable fatty oils into methyl esters suitable for fatty acid composition analysis by gas-liquid chromatography. It is particularly relevant for drying…
📜 Scope and Application of D2799-23 The ASTM D2799 – 23 standard, Standard Test Method for Microscopical Determination of the Maceral Composition of Coal, establishes the equipment and methodology for determining the physical composition of a coal sample. The analysis…
