This standard specifies a method for the determination of moisture content in thermoplastics. This method is only applicable to thermoplastics for which the melting point is below 160 ℃. The method is suitable for measuring the moisture content down to 0,005 %. This method determines the total moisture content in the test piece and includes surface moisture and moisture contained within the test piece. Because the test piece is converted to a molten state, it is assumed that all moisture is expelled.
