ASTM D 1898 – 68 (Reapproved 1989), the Standard Practice for Sampling of Plastics, delivers the fundamental principles for constructing practical and statistically sound sampling plans. Its core mission, as explicitly stated in Section 1.1, is to guide purchasers of…
🔬 Significance and Application of D1900-20 ASTM D1900-20, “Standard Practice for Carbon Black—Sampling Bulk Shipments,” provides a critical framework for obtaining representative samples from bulk carriers. The standard specifically applies to three-compartment hopper rail cars and compartmented bulk hopper trailers.…
🧪 Test Overview and Scope The ASTM D1894-24 standard provides the definitive methodology for determining the static and kinetic coefficients of friction (COF) of plastic film and sheeting. The test method covers the frictional © 2026 TNLab — This article…
ASTM D1895-24 provides standardized procedures for determining the apparent density, bulk factor, and pourability of plastic materials ranging from fine powders and granules to large flakes and cut fibers. These properties serve as critical indexes of performance for packaging, handling,…
🧪 Scope and Principle of the Conradson Carbon Residue Test The Standard Test Method D189-24 specifies the procedure for determining the amount of carbon residue left after evaporation and pyrolysis of an oil. This residue, commonly referred to as “carbon…
The ASTM D1890-15 (Reapproved 2017) standard provides a test method for measuring beta particle radioactivity in water. It is designed for beta emitters with maximum energies above 0.1 MeV and activity levels above 0.02 Bq/mL (540 pCi/L) in homogeneous water…
📐 Scope and Specimen Preparation This test method covers the determination of the California Bearing Ratio (CBR) of laboratory-compacted soils, primarily for materials with a maximum particle size less than 3/4 in. (19 mm). For larger particles, gradation is modified…
📐 Test Method Types and Detection Ranges ASTM D1886-14 (Reapproved 2021) is the definitive standard for the atomic absorption (AA) determination of nickel in water, wastewaters, and natural waters. It outlines three distinct AA methodologies tailored to specific concentration intervals.…
📐 Scope and Significance of the Method The ASTM D1889-00 standard defines the test method for determining the turbidity of water and wastewater. It is specifically applicable to the measurement of turbidity in the range of 1.0 to 40 Nephelometric…
The ASTM D1881-24 standard details a glassware test method for evaluating the foaming tendencies of engine coolants under controlled aeration and temperature conditions. This method is crucial for identifying coolants with excessive foaming or those suitable for further performance evaluation.…
