Significance and Use

These test methods are suitable for quality control, as a specification test, and for research. The water content of a polyol is important since isocyanates react with water.

TEST METHOD A: MANUAL PROCEDURE

Top

Note 2—Commercially available automated Karl Fischer titrators are used extensively.

The description of the manual systems presented below is for reference purposes and has been included in order to better define the principles of the Karl Fischer measurement.

Scope

1.1 These test methods measure water content of polyols and many other organic compounds.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
