Oil Testing, oil material certification, chemical analysis of oil
APM Testing provides A2LA accredited (ISO 17025) laboratory services for physical properties of oil, chemical analysis of oil, and oil material certification. In addition to oil testing, our laboratory also does plastic testing, metal testing, rubber testing, paint testing, plating testing, adhesive testing, circuit board testing, and other testing.
Physical Properties of Oil
Viscosity (ASTM D445) measurements of oil provide information about how well it will perform in service. Changes in viscosity over time can help to indicate degradation and/or oil contamination.
Chemical Analysis of Oil
Acid Number (ASTM D974) is a good indicator of oil degradation and whether it is likely to attack other materials. Flash Point (ASTM D92) is a good indication of volatility and GC-MS Analysis can be used to give a breakdown of the organic components in oil. Small particles in oil can be filtered out and identified using EDS Analysis. Chlorine content by XRF is an indicator of the presence of undesirable chlorides which can attack the interior of hydraulic systems. Water in oil can also corrode unprotected steel components so moisture content (ASTM E1064) measurements are also important.
Oil Material Certification
Material specifications list specific performance requirements for different grades of oil. Material specifications differ from test methods because test methods only specify how to test for a property but do not include acceptable ranges for the test results. Oil material specifications are published by many agencies including the military, SAE, and AMS.
