Traceability
of measuring equipment to the national or
the international standard is a key concern
in implementing control of inspection, measuring
and test equipment required by ISO 9000.
For measuring equipment to be traceable
to the national standard, they must be calibrated
with equipment which has been verified as
traceable to the national standard calibrated
with equipment having a higher grade of
accuracy.
Mitutoyo maintains three kinds
of standards:
- Laser for length measurement
- End standards (gauge blocks)
- Line standards (scales)
which are traceable to the national standard
at the Japan Quality Assurance Organisation
(JQA) and the National Institute of Advanced
Industrial Science and Technology (AIST).
Mitutoyo’s reference standards include
the Iodine Saturated Absorption Stabilized
He-Ne Laser for length measurement at our
Tsukuba Calibration Center, the Laser Interferometer
for gauge block calibration at Miyazaki
Plant, and the Laser Interferometer for
scale calibration at Kiyohara Plant.
Mitutoyo also maintains calibration laboratories
abroad, offering calibration services for
gauge blocks and other measuring equipment.
In the US, our calibration facilities have
established traceability to NIST; in the
UK, Germany, the Netherlands and Brazil
calibration services are provided by Mitutoyo
facilities acting as calibration agents
accredited by NAMAS, DKD, NKO and INMETRO,
respectively. |
