APPENDIX B
B. Nemko USA, Inc.’s Test Equipment & Facilities Calibration Program
Nemko USA, Inc. operates a comprehensive Periodic Calibration Program in order to ensure the validity of all test
data. Nemko USA’s Periodic Calibration Program is fully compliant to the requirements of NVLAP Policy Guide
PG-1-1988, ANSI/NCSL Z540-1 (1994), ISO 10012-1 (1993-05-01), ISO Standard 17025, ISO-9000 and EN 45001.
Nemko USA, Inc.’s calibrations program therefore meets or exceed the US national commercial and military
requirements [N.B. ANSI/NCSL Z540-1 (1994) replaces MIL-STD-45662A].
Specifically, all of Nemko USA’s primary reference standard devices (e.g. vector voltmeters, multimeters,
attenuators and terminations, RF power meters and their detector heads, oscilloscope mainframes and plug-ins,
spectrum analyzers, RF preselectors, quasi-peak adapters, interference analyzers, impulse generators, signal
generators and pulse/function generators, field -strength meters and their detector heads, etc.) and certain
secondary standard devices (e.g. RF Preamplifiers used in CISPR 11/22 and FCC Part 15/18 tests) are periodically
recalibrated by:
o
A Nemko USA-approved independent (third party) metrology laboratory that uses NIST-traceable
standards and that is ISO Guide 25-accredited as a calibration laboratories by NIST; or,
o
A Nemko USA-approved independent (third party) metrology laboratory that uses NIST-traceable
standards and that is ISO Guide 25-accredited as a calibration laboratory by another accreditation
body (such as A2LA) that is mutually recognized by NIST; or,
o
A manufacturer of Measurement and Test Equipment (M&TE), if the manufacturer uses NIST-
traceable standards and is ISO Guide 25-accredited as calibration laboratory either by NIST or by
another accreditation body (such as A2LA) that is mutually recognized by NIST; or
o
A manufacturer of M&TE (or by a Nemko USA-approved independent third party metrology
laboratory) that is not ISO Guide 25-accredited. (In these cases, Nemko USA conducts an annual
audit of the manufacturer or metrology laboratory for the purposes of proving traceabilty to NIST,
ensuring that adequate and repeatable calibration procedures are being applied, and verifying
conformity with the other requirements of ISO Guide 25).
In all cases, the entity performing the Calibration is required to furnish Nemko USA with a calibration test report
and/or certificate of calibration, and a “calibration sticker” on each item of M&TE that is successfully calibrated.
