Superseeded by:
Significance and Use:

This practice is intended to provide a method to calibrate moisture analyzers used on-stream or in the laboratory.

Scope:

1.1 This practice covers a calibration technique based on the preparation of standards of known water content. This technique is applicable to the production of standards between 20 and 2000 cm3/m3 water.

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

1.3 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.
