Significance and Use

The integrated tester is primarily used to perform on-site analysis of in-service lubricants used in the automotive, highway trucking, mining, construction, off-road mining, marine, industrial, power generation, agriculture, and manufacturing industries.

The immediate results of analysis of in-service lubricants are critical when performing proactive and preventative maintenance. On-site oil analysis, when used in conjunction with these programs, allows continuous system monitoring and contamination control potentially improving equipment up-time and equipment life.

1. Scope

1.1 This test method covers the quantitative analysis of in-service lubricants using an automatic testing device that integrates these varied technologies: atomic emission spectroscopy, infrared spectroscopy, viscosity, and particle counting.

1.2 This is suited for in-service lubricating oils having viscosities in the range between ISO 10 and ISO 320 and properties in the ranges given in Tables 1 and 2.

1.3 This test method may be used to establish trends in wear and contamination of in-service lubricants and may not give equivalent numerical results to current ASTM test methods.

1.4 This test method is not intended for use with crude oil.

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

1.6 This standard does not purport to address all of the safety concerns, 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. (Specific hazard statements are given in Section 9 and 11.3.)
