ASTM Standards Interpretation
📐 Scope, Significance, and Apparatus This test method, designated D5553 −95 (Reapproved 2019) and developed under the jurisdiction of ASTM Committee D31 on Leather, provides a procedure for determining the unsaponifiable, nonvolatile (above 80°C) matter in sulfated oils. It is…
This article provides an overview of ASTM D5551-95 (Reapproved 2019), a standard test method for determining the cloud point of oils used in the softening and stuffing of leather and in the manufacture of fat liquors and other compounds. Derived…
ASTM D5550-23 specifies a test method for determining the specific gravity of soil solids using a gas pycnometer. This method is particularly useful for soils that contain water-soluble substances or organic matter, as it avoids the use of water and…
📐 Guide to ASTM D555-84: Scope and Application ASTM D555 – 84 (Reapproved 1998), formally designated as the Standard Guide for Testing Drying Oils, is an essential document for evaluating drying oils used in paints, varnishes, and related products. Under…
📋 Scope and Limitations This standard, designated D5548-13 (Reapproved 2020), provides a laboratory screening guide for evaluating the effect of dyestuff color transfer or color loss from dyed fabrics during laundering. A critical limitation explicitly stated in the title is…
This guide outlines the essential contents for a comprehensive geostatistical site investigation report, ensuring all necessary information is included for evaluation by other geostatisticians. It is primarily intended for environmental and geotechnical applications, emphasizing the use of geostatistics to understand…
ASTM D5547-95 (Reapproved 2017) specifies a test method for determining clay and zeolite in powdered laundry detergents using atomic absorption spectroscopy. The method involves fusing the sample with lithium metaborate, measuring silicon and aluminum concentrations, and calculating the Si/Al ratio…
ASTM D5546-09 provides a standardized procedure for evaluating the solubility of asphalt binders in toluene through centrifugation. This method is essential for characterizing polymer-modified asphalts and ensuring material quality in road and paving applications. 📐 Scope and Significance This test…
🧪 Overview and Scope of ASTM D5543-21 ASTM D5543-21 specifies a rapid colorimetric test method for the determination of low-level dissolved oxygen (DO) in high-purity waters. It is specifically applicable to thermal-cycle steam condensate, deaerated boiler feedwater, boiler water, and…
🔬 Scope and Purpose of ASTM D5544-16 ASTM D5544-16 (Reapproved 2023) defines a standardized test method for the continuous, on-line measurement of Residue After Evaporation (RAE) in high-purity water. This method is essential for the semiconductor and related industries, which…
📐 Overview of ASTM D5542-16 ASTM D5542-16 specifies standard test methods for the determination of trace anions in high purity water using ion chromatography (IC) with sample preconcentration. This method is critical for quantifying contaminants like fluoride, chloride, sulfate, acetate,…
ASTM D5540-13 (Reapproved 2021) establishes a standard practice for the conditioning of flowing water samples to facilitate precise measurement of chemical and physical parameters. It applies to both continuous and grab sampling from steam or water systems under various temperature…
