📐 Scope and Methodology The ASTM D5771-21 / IP 444/09 standard defines an automated test method for determining the cloud point of petroleum products and liquid fuels using an optical detection stepped cooling technique. Issued under the jurisdiction of ASTM…
📐 Scope and Application The ASTM D5770-23 standard defines a semiquantitative micro method specifically intended for monitoring the changes in acidic constituents occurring in lubricating oils during oxidation testing. It is applicable to oils such as turbine oils, hydraulic oils,…
🔬 Scope and Significance This test method specifies the Wijs procedure for determining the iodine value—a measure of unsaturation—of tall oil fatty acids. The iodine value is expressed as the number of centigrams of iodine absorbed per gram of sample…
📏 Scope and Applicability of D5769-22 This standard test method outlines the determination of benzene, toluene, specific individual aromatic compounds, and total aromatics in finished motor gasolines using Gas Chromatography/Mass Spectrometry (GC/MS). The method is validated for finished gasoline blends,…
📐 Scope and Fundamental Terminology ASTM D5767-18 (Reapproved 2023) specifically addresses the electro-optical measurement of distinctness-of-image (DOI) gloss of coating surfaces. Under the jurisdiction of Committee E12 on Color and Appearance (Subcommittee E12.03 on Geometry), this standard defines a method…
ASTM D5766/D5766M-23, Standard Test Method for Open-Hole Tensile Strength of Polymer Matrix Composite Laminates, specifies the determination of the notched tensile strength of multi-directional polymer matrix composites. This test method is essential for evaluating the notch sensitivity and damage tolerance…
ASTM D5764 – 24, the Standard Test Method for Evaluating Dowel-Bearing Strength of Wood and Wood-Based Products, establishes the fundamental procedure for characterizing the localized crushing behavior of wood beneath a laterally loaded fastener. This material property, known as dowel-bearing…
ASTM D5765-16 establishes a standardized practice for the solvent extraction of total petroleum hydrocarbons (TPH) from soils and sediments using closed vessel microwave heating. This practice is designed to prepare samples for analytical methods such as gravimetry or gas chromatography,…
📋 Scope and Application of D5763-24 ASTM D5763-24 represents a critical standardized method for evaluating the oxidation and thermal stability of gear oils. Developed under the jurisdiction of Subcommittee D02.09.0D on Oxidation of Lubricants, the current edition was approved on…
📐 Test Method Scope and Significance This test method, designated D5762-24, covers the determination of nitrogen in liquid hydrocarbons, including petroleum process streams and lubricating oils, in the concentration range from 40 µg/g to 10,000 µg/g nitrogen. For light hydrocarbons…
