The ASTM D2846/D2846M-24 standard specifies the requirements for chlorinated poly(vinyl chloride) (CPVC) plastic hot- and cold-water distribution system components. Issued under the fixed designation D2846/D2846M, this standard covers pipe, tubing, socket-type fittings, street fittings, plastic-to-metal transition fittings, solvent cements, andā¦
📋 Scope and Referenced Documents ASTM D2847-22 is a standard practice that provides an updated procedure for evaluating the corrosion protection and performance of engine coolants in passenger car and light truck service. It closely imitates current vehicle and engineā¦
📐 Scope and Significance This test method, designated D2844/D2844M-18, covers the procedure for testing both treated and untreated laboratory compacted soils or aggregates using the stabilometer and expansion pressure devices. The results are indicative of performance when these materials areā¦
ASTM D2845-08 establishes a comprehensive standard test method for the laboratory determination of pulse velocities—both compression (P) and shear (S) waves—in rock specimens. It outlines the equipment, procedures, and calculation methods required to derive ultrasonic elastic constants for isotropic orā¦
📐 Scope and Core Measurement Principles D2843-22 is a fire-test-response test method that details a standardized laboratory procedure for measuring and observing the relative amounts of smoke obscuration produced by the burning or decomposition of plastics. The core measurement isā¦
ASTM D284-88 (Reapproved 1999) establishes standardized test methods for the chemical analysis of mercuric oxide pigment. These procedures are intended to provide a quick and reliable means of measuring the purity of the pigment to determine if it meets agreed-uponā¦
📐 Scope and Standard Overview ASTM D2842-19 specifies the standard test method for determining water absorption of rigid cellular plastics. The procedure measures the change in buoyant force resulting from immersion under a precise 5.1 cm (2 in.) head ofā¦
📐 Specimen Geometry and Types The standard D2838−18 applies to heat‑shrinkable plastic film and thin sheeting. Strict geometric requirements govern the test specimens. Material thickness must be less than 1.0 mm (0.04 in.), while film (a sub‑category of sheeting) isā¦
📌 Scope and Significance of D2839-16 This standard practice provides a method for preparing polyethylene samples specifically for density determination using the density-gradient technique outlined in Test Method D1505. The sample preparation relies on producing a consistent strand via anā¦
📋 Scope and Composition ASTM D2835 – 89 (Reapproved 2017) covers a polychloroprene-based lubricant formulated to facilitate the insertion and positioning of preformed elastomeric compression seals in concrete pavement joints. The lubricant must contain soluble phenolic resins blended with antioxidantsā¦
