D1153-22 – Standard Test Method Technical Guide
🎯 Scope and General Requirements
ASTM D1153-22 defines the specification for methyl isobutyl ketone (MIBK, 99.0 % grade), also known chemically as 2-methyl-4-pentanone. This standard is essential for ensuring quality in solvent applications, particularly within the paint, varnish, lacquer, and related coatings industries. The specification requires that all conformance determinations be made using the rounding-off method of Practice E29, applied “to the nearest unit” in the last significant digit. All property limits are expressed in SI units, and this standard is approved for use by agencies of the U.S. Department of Defense.
⚠️ Safety and Regulatory Compliance: Per Sections 1.2 and 1.5, users must consult the supplier’s Material Safety Data Sheet (SDS) for specific hazard information. This standard does not purport to address all safety concerns; users are responsible for establishing appropriate safety, health, and environmental practices prior to use.
