📐 Scope and Composition Requirements This specification, ASTM D209‑81 (Reapproved 2023), covers the pigment commercially known as lampblack. The pigment is made by burning oils or tars to form a deposit of carbon (soot). It must be high grade and…
🧪 Overview and Significance This standard, ASTM D2085-89, specifies the lime ignition method for determining chloride in pentachlorophenol (PCP) treating solutions and treated wood. This chloride measurement is used to calculate PCP concentration. The method is applicable for up to…
ASTM D2086-22 is the industry standard test method for determining the total acidity, expressed as acetic acid, in refined vinyl acetate and acetaldehyde. This titration-based method, conducted under carefully controlled conditions, provides a reliable means for quality assurance and verification…
📐 Understanding the Calculation Method for Fatty Amines ASTM D2083-92 provides a standardized computational approach for determining the percentages of primary, secondary, and tertiary amines in fatty amine samples. This method is specifically designed for materials containing only fatty primary…
⚙️ Overview of the Oscillating Disk Cure Meter Method ASTM D2084-19, formally designated as the “Standard Test Method for Rubber Property—Vulcanization Using Oscillating Disk Cure Meter,” is the internationally recognized standard for determining the vulcanization characteristics of rubber compounds. Originally…
This standard, jointly developed by ASTM and the American Oil Chemists’ Society (AOCS), establishes a procedure for determining the pH of fatty quaternary ammonium chlorides through the preparation and measurement of a 5% solution. 🧪 Reagents and Equipment Specifications The…
ASTM D2082 – 92 (Reapproved 1998), also known as the Standard Test Method for Percent of Non-Amines in Fatty Nitrogen Compounds, defines a precise ion-exchange chromatographic procedure for determining non-amine components in fatty amines and diamines. This joint ASTM and…
🧪 Overview, Scope, and Summary of ASTM D2079-92 ASTM D2079-92 (Reapproved 1998) provides a standardized procedure for the quantitation of nonvolatile matter, commonly referred to as solids, in fatty quaternary ammonium chlorides. These quaternary ammonium compounds are widely used in…
📖 Scope and Overview This test method, designated D2080-92, provides a procedure for determining the average molecular weight of fatty quaternary ammonium chlorides. The method involves converting the sample to an acetate form, performing a potentiometric titration, and applying corrections…
The ASTM D2076-92 (Reapproved 1998) standard, jointly developed with the American Oil Chemists’ Society (AOCS), provides definitive test methods for determining the acid value and amine value in fatty quaternary ammonium chlorides. These parameters are crucial for quality control, assessing…
