*OPV = OELCHECK Test Prescription
OELCHECK uses the latest analysis equipment.
Our test equipment has been developed in cooperation with well-established manufacturers with a special focus on the requirements to analyze lubricants which can sometimes be highly viscous. An experienced team of chemists and laboratory technicians operate all the different analysis devices and process up to 1,000 samples per day.
All operations in the OELCHECK laboratory are subject to quality management and environmental management. OELCHECK has been certified in accordance with ISO 9001 already since 1995 and in accordance with ISO 14001 since 2001. Furthermore, since 2009 certain test methods are accredited according to DIN EN ISO/IEC 17025:2005.
