Single Test Verification Material (STVM) – Gas Oil
Produced in general accordance with the principles of ISO 17034 and ISO 33405, the Single Test Verification Material (STVM) Gas Oil provides a certified value for a single test method and has been characterised using a network of competent laboratories to provide international traceability. It is a highly cost effective solution to help meet verification requirements for audited laboratories and those which comply with ISO 17025.
The STVM Gas Oil is supplied with full documentation including Safety Data Sheet (SDS), in tamper evident security packaging. It comes with a 2 year shelf life from date of manufacture.

The Gas Oil Single Test Verification Material allows routine monitoring of instrument performance and is also particularly helpful in training personnel on new equipment and test methods.
Incorrect determination of a result can have far reaching financial and safety implications. The growing use of automated instrumentation increases the possibility that incorrect results may go undetected and in addition the early indication of bias is a useful warning to minimise production ‘giveaway’.
The volume of verification material in each container has been chosen to ensure that there is little wastage after completion of verification tests, and reducing the risk of using a verification material that has been accidently contaminated by another user.
Certification: the Single Test Verification Material (STVM) Gas Oil is supplied with a certificate of measurement which gives a certified value for the test method covered by the material.
