Standard Test Method for Water in Engine Coolant Concentrate by the Karl Fischer Reagent Method

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 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.4 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.
