Gauge Blocks

Series 516

9. Closest Expansion Coefficient to Steel
The thermal expansion coefficient of a CERA Block is quite similar to that of a steel gauge block.
10. Highly Resistant to Dropping and Impact
The CERA Block material is one of the toughest ceramics. It is extremely difficult to crack a CERA
block in normal use.

Differences in the dimension between some
materials and steel that are obtained when
measuring testpieces with a length of 100 mm at

each temperature.

Grade and Application
The following information can be used to select the gauge block grade according to usage (speci-
fied by DIN861, BS4311, JIS B 7506 and EN ISO 3650).
Grade 2:
These gauge blocks are intended for shop floor use to set and calibrate fixtures as well as precision
instruments.
Grade 1:
This grade is used within an inspection area to verify the accuracy of plug and snap gauges as well
as for setting electronic measuring devices.
Grade 0:
These higher accuracy gauges are intended for use within a controlled environment by skilled in-
spection staff. Mainly used as reference standards for setting high precision measuring equipment
and for the calibration of lower grade gauge blocks.
Grade K:
Gauge blocks of this accuracy are intended for use within a temperature controlled inspection
room or calibration laboratory. They should be used as masters with certificates against other
gauge blocks which are calibrated by comparison.

Certificates
ILAC
The International Laboratory Accrediation Cooperation is an international cooperation of laborato-
ry and inspection accrediation bodies. The member bodies signed the ILAC MMutual Recognition
Arrangement (MRA) which guarantees a cross approval of certificates from accredited laboratories
from other countries. The Signatories to the ILAC arrangement are almost all European countries.

JCSS
Mitutoyo Gauge Block Sets can be delivered with a JCSS Certificate of Calibration (Japan Calibra-
tion Service System). A JCSS Certificate of Calibration is comparable with e.g. DAkks, COFRAC, RvA
or UKAS Certificate of Calibration. Refer to ILAC this calibration result may be accepted interna-
tionally.
