🔬 Overview and Scope This standard, designated D 2077 – 92 (Reapproved 1998), specifies a test method for determining the ash content in fatty quaternary ammonium chlorides. The ash is defined as the nonvolatile matter remaining after the specimen is…
📜 Scope and Significance of ASTM D2078 ASTM D2078-86 (Reapproved 1995) specifies the standard Wijs procedure for determining the iodine value of fatty quaternary ammonium chlorides. This value quantitatively measures the unsaturation (carbon-carbon double bonds) in the alkyl groups, expressed…
📐 Scope and Definitions These test methods, designated D2074-07 (Reapproved 2019), cover the indicator procedure for determining the total, primary, secondary, and tertiary amine values of fatty amines. They are not applicable to fatty amidoamines and fatty diamines. The values…
🧪 Test Overview and Significance This test method covers the determination of the iodine value of fatty amines, amidoamines, and diamines using the Wijs procedure. The iodine value is a measure of unsaturation in the alkyl group, expressed as percent…
ASTM D2072-92 (Reapproved 1998) defines the standard procedure for determining water content in fatty nitrogen compounds using a Karl Fischer back-titration method. Developed jointly by ASTM and the American Oil Chemists’ Society, this test method is critical for verifying the…
🧪 Significance and Scope of D2073-92 ASTM D2073-92, jointly developed by ASTM and the American Oil Chemists’ Society (AOCS), provides referee test methods for the potentiometric determination of amine values in fatty amines, diamines, and amidoamines. These values are critical…
🧪 Test Method Overview and Significance ASTM D2070-24a, the Standard Test Method for Thermal Stability of Hydraulic Oils, is designed to evaluate the thermal stability of hydrocarbon-based hydraulic oils. While the test is primarily thermal, the standard acknowledges that oxidation…
📐 Scope and Covered Compounds These test methods cover the testing of fatty nitrogen products. They were prepared jointly by ASTM and the American Oil Chemists’ Society. The compounds covered include: Fatty Amines: fatty primary amines, difatty secondary amines, and…
📋 Scope and Classification of Marine Fuels ASTM D2069-91 (Reapproved 1998), an American National Standard, provides the specification for petroleum fuels used in marine diesel engines and boilers. This standard is technically equivalent to ISO 8217:1987(E) and establishes the required…
🧪 Introduction and Scope ASTM D207 – 55 (Reapproved 1995) e1 establishes the standard specification for Dry Bleached Lac, a material commonly referred to as “bone-dry,” “bac-dry,” or “kiln-dry” bleached lac. This standard, under the jurisdiction of ASTM Committee D01.33…
