Grease testing and analysis for machinery, aviation, land, marine and industrial applications.

Intertek Caleb Brett

Grease tests are performed by Intertek to IP, ASTM, Defence Standard and other regulatory test methods and protocols. A wide suite of test rigs and test methods are available to assess grease performance. Grease sample testing is supported by an experienced team of consultants, who are members of the SAE, AMS-M, ELGI, NLGI and EI grease committees and can advise on test method selection and interpretation of results.

The Intertek grease testing laboratories are independent of lubricant and equipment manufacturers, and are ideally placed to conduct testing. Grease analysis of a sensitive nature, such as generating data for qualification approval, defect investigations, comparisons of different brands of grease and compatibility between different brands or grades of grease, is available at the Farnborough UK laboratory.

Condition based grease testing laboratories are located across the world, providing local support when you need it.

Grease condition monitoring:

• Intertek offers condition monitoring services which include elemental analysis, PQ (particle quantifier) and debris analysis for grease applications.

Grease Compatibility Testing

• Clients may choose to switch to another grease product for a number of reasons including cost-saving, performance improvement and discontinuation of the in-service product. When switching grease product, it is vital to ensure compatibility of the new product to prevent any reduction in performance which could lead to equipment damage and operational downtime.

• Intertek can offer grease compatibility testing to ASTM D6185, Standard Practice for Evaluating Compatibility of Binary Mixtures of Lubricating Greases.
