Overview
ASTM D6368-06(2023) is the internationally recognized standard specification developed by ASTM International for vapor-degreasing solvents based on stabilized normal-propyl bromide (nPB) as well as technical grade n-propyl bromide. This standard defines quality and purity requirements to ensure safe and effective use of nPB solvents in industrial vapor degreasing applications.
The document establishes criteria for both stabilized nPB blends and technical grade nPB, covering essential physical and chemical properties. These requirements are intended to help manufacturers, suppliers, and end-users maintain product consistency, performance, and regulatory compliance during vapor cleaning processes.
Key Topics
- Specification for n-Propyl Bromide (nPB) Solvents: The standard delineates the required properties for stabilized nPB, including boiling point, acidity, water content, appearance, color, free halogen presence, nonvolatile residue, acid acceptance, and resistance to aluminum corrosion at reflux.
- Technical Grade n-Propyl Bromide: Separate requirements are outlined for technical grade nPB, used as the base for vapor degreasing blends and azeotropic mixtures. These properties include specific gravity, content and purity of nPB and iso-propyl bromide, and maximum allowable impurities.
- Blends and Azeotropic Mixtures: Any blends intended for vapor degreasing must be created from technical grade nPB meeting the standard’s criteria, ensuring uniform product quality throughout different solvent formulations.
- Referencing Other Standards: The document references various ASTM test methods for verifying solvent properties and compliance, as well as U.S. government regulations for packaging and hazard communication.
Applications
Vapor-degreasing solvents based on nPB are widely used for:
- Industrial Component Cleaning: Removing oils, greases, waxes, and contaminants from metal parts and assemblies in manufacturing, aerospace, automotive, and electronics industries.
- Precision Cleaning: Preparing components requiring high cleanliness levels prior to assembly, coating, or further processing.
- Blending of Custom Solvents: Creating stabilized nPB blends and azeotropic mixtures to suit particular cleaning requirements, while ensuring consistent quality based on technical grade nPB.
Benefits of conformance to ASTM D6368-06(2023):
- Consistent and reliable cleaning performance.
- Reduced equipment corrosion and maintenance issues.
- Compliance with international quality and safety standards.
- Streamlined sourcing for industrial operations requiring high-purity vapor-degreasing solvents.
