ASTM D2916-09(2023) PDF

Overview

ASTM D2916-09(2023): Standard Specification for Isophorone defines quality and purity requirements for isophorone volatile solvents intended for use in paints, varnishes, lacquers, and related products. Developed by ASTM International, this specification addresses the critical properties and testing methods necessary to ensure safe and consistent performance of isophorone in industrial and commercial coating formulations.

Isophorone (98% grade), also known as 3,5,5-trimethyl-2-cyclohexene-1-one, is a key ketone solvent widely used in the production and application of various coatings and chemical intermediates. This standard establishes the criteria for conformance to support manufacturers, suppliers, and end users in achieving global compliance and product reliability.

Key Topics

• Product Requirements: Details the mandatory quality aspects for isophorone, such as apparent specific gravity, color, distillation range, purity, acidity, and water content.
• Testing and Sampling: Specifies test methods and sampling practices, referencing established ASTM procedures, for verifying each property:
  • Specific Gravity: ASTM D4052 or D268
  • Color: ASTM D1209 or D5386
  • Distillation Range: ASTM D1078
  • Acidity: ASTM D1613
  • Water Content: ASTM D1364
• Packaging: Requires that packaging size and type be agreed upon by buyer and supplier, and that all packaging complies with relevant transportation and regulatory guidelines.
• Units and Compliance: All measurements are standardized in SI units, and rounding of values follows Practice E29 for uniformity.
• Health and Safety: Recommends users consult the relevant Safety Data Sheets and establish appropriate procedures for safe handling, use, and disposal.

Applications

Isophorone’s excellent solvency and evaporation characteristics make it suitable for a variety of applications, which are addressed by this ASTM standard:

• Industrial Coatings: Used as a solvent in paints, varnishes, and lacquers for improved film formation and application properties.
• Chemical Manufacturing: Serves as an intermediate in the synthesis of other chemicals and resins.
• Formulation Consistency: Ensures that isophorone supplied to manufacturers meets quality standards for predictable performance in final products.
• Regulatory Compliance: Supports procurement and quality assurance processes by providing a clear benchmark for acceptance testing.

By adhering to ASTM D2916-09(2023), stakeholders can ensure product consistency, meet international regulatory requirements, and optimize the performance of coating systems and chemical products.
