Abstract
This specification establishes the requirements for three grades of 1,1,2-trichloro 1,2,2-trifluoroethane solvent, as follows: Type I, electronic or ultra-clean grade; Type II, standard or vapour-degreasing grade; and Type IIA, general purpose grade packaged in a pressurized container. Each grade shall adhere to individually specified values of the following chemical and physical properties: boiling point at standard barometric pressure; chemical purity; moisture content; chloride ions content; specific aqueous conductance; acid number; and residue content.
Scope
1.1 This specification establishes the requirements for three grades of trichlorotrifluoroethane solvent:
1.1.1 Type I electronic or ultra-clean grade,
1.1.2 Type II standard or vapor-degreasing grade, and
1.1.3 Type IIA general purpose, packaged in a pressurized container grade.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.
