Appendix E: Control and Calibration of Measuring and Test Equipment - Continued

DOE-STD-1054-93

A PPEN D IX E (Cont.)

This lesson has the following trainee enabling objective:

Explain the purpose and function of an M&TE program.

M&TE includes instruments, tools, and devices used to calibrate or verify installed

field equipment. Typically, M&TE equipment is defined as a primary or secondary

standard. A primary standard is traceable to NIST and is environmentally controlled

at the owner facility. A secondary standard is calibrated to the primary and used for

field calibration of installed equipment. Additional discussions on M&TE include

the following:

All calibrations of M&TE should be traceable to NIST. The primary standard

is traceable to NIST, the secondary to the primary, and field equipment to the

secondary. The use of primary standards for field use should be discouraged.

Calibration procedures should be used for all primary to secondary

calibrations. Only qualified technicians should perform these calibrations.

The interval of calibrations should be determined based on the manufacturer's

recommendations, the M&TE usage, and the M&TE's historical reliability.

Primary and secondary standards should be stored in an environmentally

controlled area. Issuance of M&TE should be controlled to prevent M&TE

damage due to wrong application, misuse of the M&TE by unqualified

workers, and field calibrations with out-of-tolerance M&TE.

A master list of all controlled M&TE should be maintained to include the

following:

description of the equipment,

discrete identification number,

calibration procedures and periodic interval of calibration, and

ranges of calibration and required accuracy.

Discuss with the trainees the facility's M&TE program.
