Calibration according to DAkkS
As part of the quality management
standard ISO 9001, inspection equipment
relevant to quality must be monitored
regularly, and must also be traceable to a
national standard in concordance with the
International System of Units (SI).
HEIDENHAIN supports its customers in
this task with its own calibration laboratory
for digital linear and angle encoders, which
has been accredited since 1994.
The calibration laboratory at HEIDEN-
HAIN operates according to DIN EN ISO/
IEC 17025, and has been accredited by
the German Accreditation Body (DAkkS).
HEIDENHAIN calibration certificates —
granted by the accredited laboratory—doc-
ument the traceability to the International
System of Units (SI).
The DAkkS is a signatory to the multilateral
agreement of the European co-operation
for Accreditation (EA) and of the Interna-
tional Laboratory Accreditation Cooperation
(ILAC) for the mutual recognition of calibra-
tion certificates.
Calibration certificates from HEIDENHAIN
are recognized in most industrial countries.
The calibration certificate from HEIDEN-
HAIN gives the user certainty about the
accuracy of the encoder, and also certifies
the traceability to the International System
of Units (SI) necessary for ISO 9001.
The calibration laboratory at HEIDENHAIN
is equipped for all digital linear and angle
encoders where accuracy is of extreme
importance:
• AT, CT, MT, ST and length gauges (also in
conjunction with ND 28x, EXE or IBV
subsequent electronics)
• LC, LF, LIDA, LIP, and LS linear encoders
• ECN, ROC, ROD, and RON angle
encoders
Length gauges from HEIDENHAIN can be
calibrated no matter what interface they
have. If the measuring chain includes a
subsequent electronics unit from HEIDEN-
HAIN, this unit can also be included in the
calibration.
The following are measured and certified:
• Deviation span with retracting plunger
• Deviation span in the part measuring
span
• Repeatability with five measurements
(extended plunger)
