📜 Scope and Regulatory Framework This guide, formally designated ASTM D6346-17, provides a standardized framework for Household Hazardous Waste (HHW) programs. Its primary purpose is to guide the acceptance, segregation, and packaging of materials collected through HHW events and facilities…
📐 Standard Overview and Scope ASTM D6347/D6347M – 05 (Reapproved 2018) defines the standard test method for determining the bulk density of stockpiled coal using instrumentation that measures the relative backscatter of nuclear gamma radiation throughout the depth of the…
📖 Scope and Classification of Organic Compounds ASTM D6345-10 serves as a definitive standard guide for the selection of active integrative sampling methods for Volatile Organic Compounds (VOCs) in air. It provides critical assistance in choosing between two primary approaches:…
📐 Scope and Material Specifications This standard compiles test methods for evaluating thin thermally conductive solid materials used in electrical insulation and dielectric applications. These materials are typically compliant sheets produced by mixing thermally conductive particulate fillers with organic or…
📐 Apparatus and Specimen Requirements The impactor defined in Section 5.1 is a solid steel cylindrical rod with a full radius hemispherical end. It is 32 mm ± 2 mm in diameter, approximately 115 mm in length, and has a…
ASTM D6342-22 is a comprehensive practice that defines the procedures for determining the hydroxyl number of polyols used in polyurethane production through Near Infrared (NIR) spectroscopy. The hydroxyl number, defined as the milligrams of potassium hydroxide equivalent to the hydroxyl…
ASTM D6341-21 establishes a standard method for evaluating the linear coefficient of thermal expansion (CLTE) of plastic lumber and plastic lumber shapes, specifically in their as-manufactured form. This method addresses the unique characteristics of recycled plastic products, which are often…
This classification system, formally titled ASTM D6339 – 11 (Reapproved 2019), establishes a standardized framework for specifying syndiotactic polystyrene (SPS) materials intended for molding and extrusion. Encompassing homopolymers, copolymers, blends, and impact-modified grades, this standard provides a precise language for…
🧪 Introduction to Aerobic Biodegradation of Radiolabeled Plastics ASTM D6340-98 (Reapproved 2007) establishes standard test methods for the direct determination of the rate and degree of biological oxidation of carbon in plastic materials. These methods require that the target component…
📐 Scope and Composition of HCTPV ASTM D6338‑17 defines a standard classification system for Highly Crosslinked Thermoplastic Vulcanizates (HCTPV), a specialized class of thermoplastic elastomers (TPE). The standard specifies that these materials consist of two or more polymer systems: a…
