VHG Labs Proficiency Testing Program (PTP) for Oil Analysis


The VHG PTP has been specially designed for analytical laboratories that analyze new or used oils for metals, sulfur, viscosity, or particle count.  The PTP is intended to provide laboratories with a method of monitoring their analytical performance as measured against Certified Reference Materials (CRMs) and is ISO/IEC 17043 accredited.
