Scope

This standard specifies the test methods for determining trace moisture in industrial fluorinated hydrocarbons: Karl Fischer method - volumetric method, Karl Fischer method - coulometric method, and electrolysis method. The electrolysis method is not suitable for fluorinated hydrocarbons with relatively high boiling points. This standard is applicable to the determination of trace moisture in industrial fluorinated hydrocarbons.
