ASTM D123-23 is the definitive compilation of textile terminology, developed under the jurisdiction of ASTM Committee D13 on Textiles and directly managed by Subcommittee D13.92 on Terminology. This standard consolidates definitions specific to the textile industry, ensuring consistency across various…
📐 Scope and Application This test method covers the evaluation of the flammability of textile fabrics as they reach the consumer for apparel. It employs a 26-gauge hypodermic needle as the ignition source to classify apparel textiles and identify those…
The ASTM D1234-13 standard establishes the procedures for sampling and measuring the unstretched staple length of grease wool, pulled wool, mohair, and other animal fibers in staple form. This test method is an industry standard for acceptance testing of commercial…
This article provides an overview of ASTM D1227/D1227M – 13 (Reapproved 2024), which specifies requirements for emulsified asphalt coatings used for protective roofing applications. The standard covers two types of emulsions, classified by their composition and reinforcement. 🏗️ Product Classification…
📐 Scope and Significance of ASTM D1229-03 ASTM D1229-03 (Reapproved 2024) specifically evaluates the ability of vulcanized rubbers to recover from deformation after being compressed at room temperature and then exposed to low temperatures. This method is critical for rubber…
📊 Key Measured Properties and Standards Specular gloss is reported in gloss units (GU) based on a theoretical perfect mirror assigned a value of 384.4 GU. The practical working standard is a polished black glass surface with a refractive index…
ASTM D1224 – 92 (Reapproved 2006) establishes standard test methods for determining zinc and cadmium in paper and highly opaque pigments. The standard presents three distinct analytical pathways—Polarographic (Method A), Gravimetric and Volumetric (Method B), and Atomic Absorption (Method C)—enabling…
📜 Scope and Summary of D1214-10 ASTM D1214-10 (Reapproved 2020) specifies a standardized test method for determining the particle size distribution (sieve analysis) of glass spheres. These spheres are used as retroreflective media in pavement markings and in various industrial…
📐 Test Method Overview and Scope ASTM D1217-20 is a standard test method for measuring the density and relative density (specific gravity) of liquids using a Bingham pycnometer. It is specifically applicable to pure hydrocarbons or petroleum distillates that boil…
🔬 Scope and Applicability ASTM D1218-21 specifies a test method for measuring the refractive index of transparent and light-colored hydrocarbon liquids with accuracy to four decimal places. The refractive index range covered is from 1.3300 to 1.5000 at temperatures between…
