This test method is used for the determination of moisture in most plastics. Plastics containing volatile components, such as monomers and plasticizers, may contaminate the electrolytic cell, used in the test, causing incorrect results. This test method is suitable for measuring moisture over the range from 0.005% to almost 100%. The values stated in SI units are to be regarded as the standard. 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-There is no similar or equivalent ISO standard.
