ASTM D3739-19 defines the standard practice for calculating and adjusting the Langelier Saturation Index (LSI) specifically for the concentrate stream of reverse osmosis (RO) devices. Accurately determining this index is critical for predicting the need for calcium carbonate (CaCO₃) scale…

📐 Scope and Classification ASTM D3735-22, under Committee D01 jurisdiction, specifies four types of VM&P naphthas: Type I (Regular), Type II (High Flash), Type III (Odorless), and Type IV (Low Aromatics). These are moderately volatile, mainly aliphatic hydrocarbon solvents used…

The ASTM D3737-18 (Reapproved 2023) practice provides the standard framework for calculating allowable properties in structural glued laminated timber (glulam). This practice governs the derivation of design values needed for engineered wood construction, relying heavily on specific material grade arrangements…

📐 Scope and Classification of High-Flash Aromatic Naphthas ASTM D3734 – 05 (Reapproved 2018), Standard Specification for High-Flash Aromatic Naphthas, provides the specification for aromatic hydrocarbon solvents that are high-flash, moderately low-volatility petroleum distillates. These solvents feature a distillation range…

ASTM D3732−23 provides a standardized framework for reporting cure times of ultraviolet (UV)-cured coatings. The core of the standard defines a “cure” not by a single physical property, but by the condition of the coating as measured by end-use performance…

🧪 Scope and Significance of ASTM D3733-93 ASTM D3733-93 (Reapproved 1998) establishes a standard test method for determining the silicon content of silicone polymers and silicone‑modified alkyds. This method is specifically applicable when silicon is present in the nonvolatile portion…

ASTM D3730-17 (Reapproved 2022) is a standardized guide covering the selection and use of test methods for High-Performance Interior Architectural Wall Coatings (HIPAC). These coatings differ from conventional paints by being formulated to be tougher, more stain-resistant, and more abrasion-resistant,…

🌿 Overview and Scope of Measurement Practices These practices encompass the extraction and measurement of chlorophyll a, b, and c, and pheophytin a in freshwater and marine plankton and periphyton. Three distinct practices are provided: spectrophotometric trichromatic, spectrophotometric monochromatic, and…

🎯 Scope and Summary of the Test Method This test method, designated ASTM D3725-78 (Reapproved 1998), covers the semiquantitative determination by gas-liquid chromatography (GLC) of herring and menhaden fish oil when present in small quantities in other drying oils and…

📋 Scope, Referenced Documents, and Key Test Methods ASTM D3728-08 (Reapproved 2012) specifically covers the requirements for 99% grade 2-Ethoxyethyl Acetate, a solvent widely used in paints, coatings, and chemical intermediate applications. The values stated in SI units are regarded…

🧪 Scope and Significance of D3723-22 This standard test method outlines a reliable procedure for determining the pigment content of water-emulsion paints using low-temperature ashing. It is ideally suited for coatings where the pigment load consists of materials thermally stable…

🧪 Composition and Chemical Requirements Standard D3724-01 (Reapproved 2019) specifies the requirements for synthetic brown iron oxide pigments used in paints and coatings. The pigment must be a manufactured iron oxide or a blend, produced via precipitation of iron salts,…
