Grease Thief® Diagnostics

In the Ecol laboratory, we have implemented the world’s most modern lubricant testing method, meeting the requirements of ASTM D7718-11 and ASTM D7918-11 standards for sampling and analysis of plastic lubricants. Grease Thief® is the only method that allows as many as 9 tests to be performed on a lubricant sample weighing as little as 1g.

Grease Thief® testing of industrial lubricants

At Ecol’s oil diagnostics laboratory, we test lubricants using the world’s most advanced Grease Thief® method, which meets the requirements of ASTM D7718 and ASTM D7918 standards for sampling and analysis of plastic lubricants.

Grease Thief® is the only method that allows as many as 9 tests (including consistency, wear, contamination, lubricant oxidation, and wear particle counts) to be performed on a lubricant sample weighing as little as 1g.

Grease Thief® at Ecol’s oil laboratory

The Ecol oil laboratory in Rybnik is the first in Central Europe to provide lubricant analysis services with Grease Thief® technology.

industrial lubricant testing

representativeness of the sample

The lubricant sample is taken each time from a critical and representative area thanks to patented sampling tools.

The one-gram sampler allows for non-contact sample preparation in the laboratory, and the sampling process itself, ensures full reproducibility and eliminates the risk of cross-contamination of samples on the test bench.

elimination of the risk of cross-contamination of lubricant samples

Cross-contamination in the industrial lubricant sampling method refers to the situation where lubricant samples taken from different locations or machines may contaminate each other. This can occur, for example, when sampling tools are used repeatedly without proper cleaning or when lubricants are stored in a way that allows contact between them. Cross-contamination can introduce false or falsified lubricant analysis results, making it difficult to accurately assess lubricant condition and diagnose potential machine failures. The Grease Thief® method, with its precision and disposable samplers, minimizes the risk of cross-contamination of grease samples, ensuring reliable analysis results.

The Grease Thief® method eliminates the risk of cross-contamination by using disposable grease samplers. Each sampler is designed to take a single sample from a specific area of the machine. Once the sample is taken, the sampler is removed, preventing contact and mixing of lubricants from different locations. This prevents contamination of grease samples with other lubricants that can affect the analysis results. The Grease Thief® method ensures full separation and independence of grease samples, which guarantees accurate and representative analysis results without the influence of cross-contamination.

FAQ

Grease Thief®: frequently asked questions

  • A full fill is required only for the consistency test. Other tests (e.g. wear, contamination, oxidation) can be performed on a smaller sample.

  • ASTM D7718 (Standard Practice for Obtaining In-Service Samples of Lubricating Grease) is a standard that defines a methodology for in-service lubricant sampling. It describes a reproducible method for obtaining samples from specific applications, including: motor-driven valves, gearboxes, standing bearings, electric motors, exposed bearings, open gears or damaged lubricating grease components.

    The standard was developed by the World Trade Organization’s Technical Barriers to Trade (TBT) Committee, in accordance with international standardization principles.

    Full description of the standard: https://www.astm.org/d7718-11r19.html

  • ASTM D7918 (Standard Test Method for Measurement of Flow Properties and Evaluation of Wear, Contaminants, and Oxidative Properties of Lubricating Grease by Die Extrusion Method and Preparation) is a standard that specifies the monitoring of wear trends, contamination, consistency, and oxidative properties of grease. It covers the analysis and evaluation of the flow properties, wear levels, contamination and oxidative state of new and used lubricating grease.

    The standard was developed by the World Trade Organization’s Technical Barriers to Trade (TBT) Committee, in accordance with international standardization principles.

    Full description of the standard: https://www.astm.org/d7918-17a.html

  • The Grease Thief® method provides representative grease samples, eliminating the risk of cross-contamination. In addition, thanks to the one-pound sampler, samples can be prepared in the laboratory without contact, which guarantees full reproducibility of the results.

  • The Grease Thief® method is useful in many industries, such as industry, transportation, energy, heavy industry, and wherever plastic lubricants are used to maintain and protect machinery.
