📐 Sampling Plan for Saturated Felts and Fabrics ASTM D146/D146M provides a precise statistical method for roll selection to ensure representative testing. As outlined in Section 3, the number of rolls selected must equal one half the cube root of…

ASTM D1460-86 (Reapproved 2020) provides a specialized technique for measuring the dimensional response of rubber vulcanizates and rubbery materials when immersed in liquids. Unlike direct volumetric methods, this test method relies on observing changes in specimen geometry through transparent apparatus…

This test method, designated D1461-17 (Reapproved 2022), covers the determination, by direct measurement, of moisture or volatile fractions of the asphalt in asphalt mixtures. The values stated in SI units are to be regarded as the standard, ensuring uniformity in…

ASTM D1458-13 specifies standard test methods for the evaluation of fully cured silicone rubber-coated glass fabrics and tapes intended for use as electrical insulation. The standard outlines a comprehensive battery of mechanical, electrical, and thermal tests to ensure material quality…

📋 Scope, Types, and Ordering Information This specification covers clear silicone varnished glass fabrics supplied as sheets, rolls, and tapes for use as electrical insulation. The materials are classified as Class 180 electrical insulating materials per IEEE Standard No. 1,…

The ASTM D1455-17 (Reapproved 2023) standard provides a definitive method for evaluating the 60° specular gloss of dried emulsion floor polish films. This standardized approach ensures consistent quality assessment by precisely defining the apparatus, substrates, and application techniques required for…

📐 Specimen Preparation and Apparatus The test method begins with a piece taken from the sample, from which a specimen is prepared using a die that cuts straight specimens with parallel sides. The specimens are approximately 150 mm (6 in.)…

📐 Test Method Scope and Applicability ASTM D1447-07 (Reapproved 2021) establishes a photoelectric test method for measuring the length and length uniformity of cotton fibers. The method applies to fibers from raw or partially processed cotton, including card mat and…

📐 Test Principle and Sample Preparation This test method, designated D1448-11, covers the determination of the micronaire reading of loose cotton fibers by measuring the resistance of a specific mass of cotton fibers to air flow under prescribed conditions. The…

ASTM D1452/D1452M-24 provides standardized guidance for soil exploration and sampling using earth augers at shallow depths. This practice is essential for obtaining disturbed soil samples that are fundamental for classification and compaction testing in geotechnical engineering. 📐 Scope and General…
