ASTM D2074 is an international standard that provides a detailed procedure for determining the amine values of fatty amines using an alternative indicator titration method . This standard is widely used in chemical analysis and quality control for products such as surfactants, lubricants, and corrosion inhibitors. Overview of ASTM D2074 The current version of the standard is ASTM D2074-07(2019) , which was reapproved in 2019. It defines the specific methods used to measure the basicity of fatty amines, expressed as the "amine value"—the number of milligrams of potassium hydroxide (KOH) equivalent to the amine basicity in one gram of sample. The standard focuses on four specific values: Total Amine Value : Total basicity of the sample. Primary Amine Value : Basicity attributed specifically to primary amines. Secondary Amine Value : Basicity attributed to secondary amines. Tertiary Amine Value : Basicity attributed to tertiary amines. Key Applications and Scope ASTM D2074 is essential for professionals in industrial fluid manufacturing and analytical laboratories. It is particularly applicable to: Fatty Amines : Long-chain alkyl amines used in industrial chemistry. Industrial Fluids : Including drilling fluids, engine oils, coolants, and hydraulic fluids where amines serve as acid neutralizers. Quality Assurance : Manufacturers use these values to verify amine content before market release or further processing.
Understanding ASTM D2074 is essential for laboratory professionals and chemical manufacturers who need to quantify the basicity of fatty amines. This standard, titled Standard Test Methods for Total, Primary, Secondary, and Tertiary Amine Values of Fatty Amines by Alternative Indicator Method , provides a reliable alternative to traditional potentiometric titration. The full ASTM D2074 PDF document is available for purchase and download through official standards bodies like the ASTM International Website and authorized distributors such as iTeh Standards or Accuris Standards Store . Overview of ASTM D2074 ASTM D2074 defines the "amine value" as the milligrams of potassium hydroxide (KOH) equivalent to the amine basicity in one gram of a sample. It is used primarily for: Total Amine Value : The combined basicity of all amine groups in the sample. Primary, Secondary, and Tertiary Amine Values : Specific breakdown of basicity based on the degree of nitrogen substitution. Scope and Applications The method is specifically designed for fatty amines used in industrial products such as: Corrosion Inhibitors : Used in lubricants, engine oils, and drilling fluids. Acid Neutralizers : Found in industrial coolants and hydraulic fluids. Polymers and Resins : Often cited in the characterization of dimer acids and fatty polyamides.

ASTM D2074 PDF: Understanding the Standard for Flexural Properties of Plastics The ASTM D2074 PDF is a widely used standard test method for determining the flexural properties of plastics. Published by the American Society for Testing and Materials (ASTM), this standard provides a comprehensive framework for evaluating the flexural strength, flexural modulus, and other related properties of plastic materials. What is ASTM D2074? ASTM D2074 is a standard test method titled "Standard Test Methods for Flexural Properties of Plastics." This standard outlines the procedures for determining the flexural properties of plastics, including flexural strength, flexural modulus, and flexural strain. The test method involves applying a load to a plastic specimen in a three-point or four-point bending configuration, measuring the resulting deformation, and calculating the flexural properties. Key Properties Measured in ASTM D2074 The ASTM D2074 PDF test method measures several key properties of plastics, including:
Flexural Strength : The maximum stress a plastic material can withstand without failing when subjected to a bending load. Flexural Modulus : A measure of a plastic material's stiffness or resistance to deformation under a bending load. Flexural Strain : The deformation of a plastic material under a bending load, expressed as a percentage of the original length.
