Standard Specification for Vapor-Degreasing Solvents Based on normal-Propyl Bromide and Technical Grade normal-Propyl Bromide

Fecha:
2018-07-16 /Active
Abstract:

This specification covers solvents based on stabilized normal-propyl bromide (nPB) for use in vapor degreasing. The standard also includes a separate specification for technicalgraden-propyl bromide. Blends and azeotropic mixtures of stabilized nPB for vapor-degreasing shall be blended from nPB meeting the specification for technical-grade nPB. Vapor-degreasing solvents based on stabilized normalpropyl bromide shall conform to the requirements of different properties such as boiling point, acidity, water content, appearance, color, free halogen, nonvolatile residue, acid acceptance, and aluminum corrosion at reflux. Blends and azeotropic mixtures of stabilized nPB with other materials for use in vapor degreasing shall be prepared from technical-grade nPB which shall conform also to requirements of different properties such as: specific gravity, boiling point, acidity, water content, appearance, color, free halogen, nonvolatile residue, normal-propyl bromide content, and iso-propyl bromide content.

Scope:

1.1 This standard covers solvents based on stabilized normal-propyl bromide (nPB) for use in vapor degreasing. The standard also includes a separate specification for technical-grade n-propyl bromide.

1.2 Blends and azeotropic mixtures of stabilized nPB for vapor-degreasing shall be blended from nPB meeting the specification for technical-grade nPB.

Note 1: Guide D3844, Practice D4276, and MNL22 provide additional important information on vapor degreasing and solvent properties.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
