Why work with us?

VHG has manufactured single and multi-element standards (both aqueous and oil-based) for more than 30 years, including petroleum standards, analytical reference standards for new and in-service oil applications, and standards for ASTM, DIN, IP, ISO, JIS and ANFOR methods, including EPA Tier 3. We also offer proficiency testing and specialise in custom blends.


Each of our products must pass rigorous quality control in our ISO/IEC 17025-certified laboratory, with many also individually accredited to ISO 17034, and all standards ship with a comprehensive Certificate of Analysis. We verify against the appropriate NIST SRM (when available), and calibrate equipment according to NIST procedures, to support your testing accuracy.
