ASTM D4126-02(2012)

Отменен
Standard Specification for Vapor-Degreasing Grade and General Solvent Grade<brk> 1,1,1-Trichloroethane (Withdrawn 2017) — 2 стр.
Причина отмены This specification covers vapor-degreasing grade and general solvent grade 1,1,1-trichloroethane. High grades of 1,1,1-trichloroethane are available but should not be evaluated by this specification.

Formerly under the jurisdiction of Committee D26 on Halogenated Organic Solvents and Fire Extinguishing Agents, this specification was withdrawn in November 2017. This standard is being withdrawn without replacement due to the manufacture and use of 1,1,1-trichloroethane having been phased out throughout most of the world. The committee is aligning itself with this and also with the efforts of the U.S. EPA Significant New Alternatives Program (SNAP).

Реферат

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.

Область применения

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.
