significance And Use:
The presence of acids or glycol esters in the ethylene glycol used to produce engine coolant is undesirable. Under conditions in an engine cooling system, the esters can hydrolyze to form glycol... View More
scope:
1.1 This test method covers the determination of free acids and glycol esters in ethylene glycol by titration.
1.2 This test method is for used on ethylene glycol used for the manufacture of engine coolant. It can not be used on formulated engine coolant. The inhibitors will interfere with the determination.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
