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,
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,
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
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).
