Audit Standards & Round Robin Standards

Audit and Round Robin Standards can be preparedtocustomer specifications forauditing their own facilities, custody transfer points, customer facilities and vendor Facilities. Blend records are kept confidential.

Round Robin Programs

A custom Round Robin program can be designed to meet specific customer needs,from preparing Calibration Standards to managing the entire program. Program records are kept confidential.

Secondary Verification of Calibration Standards

For those critical applications where a secondary verification of a DCG Calibration Standard is desired, a collaboration is available through a third party approved analytical laboratories to assist in this process.
