ASTM Standard D3370-18, “Standard Practices for Sampling Water from Flowing Process Streams,” is a critical document authorized by the U.S. Department of Defense and developed under the jurisdiction of ASTM Committee D19 on Water. It establishes standardized methods for extracting…

ASTM D3368-17 (Reapproved 2022) covers the standard specification for unfilled, unpigmented FEP resin sheet and film with a thickness less than 3.175 mm (0.125 in.). The standard establishes a classification system based on material performance and intended use, allowing for…

ASTM D3366-18 specifically covers the visual measurement of color in molten maleic anhydride on the Platinum-Cobalt (Pt-Co) scale (0–100 range). It requires testing a fresh melt prepared at 60°C and a second specimen after an accelerated aging period of 2…

📐 Scope and Principles of the Test Method The ASTM D3367-21 standard establishes a definitive procedure for determining the plasticizer sorption of poly(vinyl chloride) (PVC) homopolymers under a controlled applied centrifugal force. This quantitative method is crucial for evaluating the…

The ASTM D3363-22 standard describes a widely utilized, rapid screening method for evaluating the hardness of organic coating films through the use of standard drawing leads or pencils. Often referred to as the “pencil hardness test,” this method is essential…

🧪 Standard Overview and Scope ASTM D3364-99 (Reapproved 2019) is a specialized extension of Test Method D1238, specifically designed for measuring the flow rates of poly(vinyl chloride) (PVC) compounds. This test method uniquely detects and controls the various polymer instabilities…

📐 Scope and Significance of D3361/D3361M ASTM D3361/D3361M defines a standard practice for accelerating the exposure of paints and related coatings using an unfiltered open-flame carbon-arc device. This practice covers the selection of test conditions, preparation of test specimens, and…

📐 Scope and Applicability of the Standard ASTM D3362-05 is a standardized gas chromatographic test method for determining the purity of commercially available acrylate esters. It specifically covers methyl acrylate, ethyl acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate. The method simultaneously…

ASTM D3359 – 23 outlines standard test methods for assessing the adhesion of relatively ductile coating films to metallic substrates. The procedure involves applying and removing pressure-sensitive tape over cuts made in the coating film. These test methods are designed…

📐 Scope and Application This test method covers the determination of the particle-size distribution in the sub-sieve size range of common extender pigments such as aluminum silicate (kaolin clay), magnesium silicate (talc), calcium carbonate (calcite or dolomite or precipitated calcium…
