ASTM D6130 - Elemental Analysis by ICP, Aqueous / Coolants / Sulfur

Significance and Use

4.1 Some engine coolants are formulated with silicon con-taining additives. This test method provides a means of determining the concentration of dissolved or dispersed ele-ments which give an indication of this additive content in the engine coolant.

1. Scope

1.1 This test method covers the determination of silicon in engine coolant by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). Silicon can be determined as low as the range of 5 ppm by this test method. Other elements also found in engine coolant can be determined by this method. This test method is applicable to the determination of dissolved or dispersed elements.

1.2 This test method is applicable to both new and used engine coolant.

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