ASTM D6569-00
Historical Standard: ASTM D6569-00 Standard Test Method for On-Line Measurement of pH 1
SUPERSEDED (see Active link, below)
ASTM D6569
1. Scope
1.1 This test method covers the continuous determination of pH of water by electrometric measurement using the glass, the antimony or the ion-selective field-effect transistor (ISFET) electrode as the sensor.
1.2 This test method does not cover measurement of samples with less than 100 S/cm conductivity. Refer to Test Method D 5128.
1.3 This test method does not cover laboratory or grab sample measurement of pH. Refer to Test Method D 1293.
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.
