ASTM D1123-99
Historical Standard: ASTM D1123-99 Standard Test Methods for Water in Engine Coolant Concentrate by the Karl Fischer Reagent Method
SUPERSEDED (see Active link, below)
ASTM D1123
1. Scope
1.1 These test methods cover the determination of the water present in new or unused glycol-based coolant concentrates using a manual (Test Method A) or an automatic (Test Method B) coulometric titrator procedure.
1.2 Many carbonyl compounds react slowly with the Fischer reagent, causing a fading end point and leading to high results. A modified Fischer reagent, procedure is included that minimizes these undesirable and interfering reactions.
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. For specific hazards statements see Sections 8 and 16.
