Organization: ASTM International
Publication Date: 10 June 1999
Status: inactive
Page Count: 7
ICS Code (Examination of physical properties of water): 13.060.60
scope:

1.1 This test method covers the determination of electrical conductivity and resistivity of high purity water samples below 10 [mu]S/cm (above 0.1 Mohm-cm). It is applicable to both continuous and periodic measurements but in all cases, the water must be flowing in order to provide representative sampling. Static grab sampling cannot be used for such high purity water. Continuous measurements are made directly in pure water process lines, or in side stream sample lines to enable measurements on high temperature or high pressure samples, or both.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 This standard does not purport to address all of the safety problems, 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.
