This specification covers the requirements and corresponding test methods for vapor-degreasing grade perchloroethylene. When tested, materials shall conform to the following physical properties: specific gravity; distillation range (initial boiling point and dry point); acidity as HCl; alkalinity as NaOH; water content; appearance; color in Pt-co units; halides content; nonvolatile residues content; acid acceptance; and copper corrosion behavior.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers vapor-degreasing grade perchloroethylene.
