Abstract
This specification covers the requirements for vapor-degreasing grade and general solvent grade 1,1,1-trichloroethane. High purity grades are also available but should not be evaluated by this specification. Both grades shall be undergo tests and should conform accordingly to the following properties: specific gravity; distillation range (initial boiling point and dry point); acidity (as HCl); alkalinity and acid acceptance (as NaOH); water content; appearance; color (Pt-Co scale); halide (as Cl-) content; nonvolatile residue content; performance in aluminium scratch test; and purity.
Scope
1.1 This specification covers vapor-degreasing grade and general solvent grade 1,1,1-trichloroethane. High purity grades of 1,1,1-trichloroethane are available but should not be evaluated by this specification.
1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—Practices D3844 and D4276, STP 403A and MNL2 provide additional important information on vapor degreasing and solvent properties.
