p-NITROANILINE

This test method covers the determination of pentane insolubles for particles exceeding 0.8 μm in new and used lubricating oils. Pentane insolubles with particle sizes less than 0.8 μm may be studied with appropriate size membrane filters. Particle sizes above or below 0.8 μm can be studied. The precision of this test method has been determined only at 0.8 μm. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Analysis Type (Application Method): Gravimetric
