CALIBRATION PROCEDURE FOR IMTE
6.0
Calibration Procedure
6.1
The calibration procedure shall include the method and interval of
calibration, which is based on the type of Equipment stability characteristics,
required accuracy, intended use, and other conditions affecting
measurement control.
6.2
The QCM shall establish/implement the calibration procedure for each IMTE to
be controlled.
7.0
Control of Calibration
7.1
Upon receipt of requested IMTE with relevant documents, it shall be ensured
that whether calibration status is available or not and include in the
Calibration Master List.
7.2
IMTE use Log shall be maintained for all the IMTE’s.
7.3
Specific written calibration procedures shall be used and comparison
standards such as weights, gauges, etc. shall be traceable to National or
International Standards. Manufacturer's recommended written instructions
may be adopted for certain IMTE.
7.4
The calibration results shall be documented and controlled as QA Records.
7.5
Calibration will be performed by an authorized calibration agency.
7.6
Environmental conditions shall be suitable for the calibrations, inspections,
measurements and tests being carried out.
7.7
IMTE shall be handled, preserved and stored in a good condition to maintain
accuracy and fitness for use.
7.8
The calibration status shall be recorded.
7.9
Where test hardware (e.g.jigs, fixtures, template, patterns) or test software is
used as suitable forms of inspection, it shall be checked to prove that it is
capable of verifying the acceptability of product prior to release for use
during construction and shall be rechecked at appropriate internals.
7.10 Measurement data shall be made available, when required by the Client, for
verification that functionally adequate.

CALIBRATION PROCEDURE FOR IMTE
8.0
IMTE Identification
8.1
IMTE shall be identified with unique identification number to establish
accurate records of current IMTE conditions.
8.2
Scrapped IMTE identification numbers will not be re-assigned.
9.0
Frequency of Calibration
9.1
IMTE shall be calibrated at pre-determined interval.
9.2
Contractor IMTE listing shall be prepared by the QCM and include the
calibration frequency/interval based on the frequency of IMTE use and the
importance of the item and measurements being made and the criteria
designated:
9.3
Re-calibration shall be performed at pre determined intervals and when the
accuracy is in question.
10.
Use Log
10.1 A history of use log shall be maintained for each measuring and test
equipment. This log shall document the date and location of these
equipment were used with enough detail to enable re-checking of the work,
incase of error in the test equipments exceed the acceptable range during
recalibration.
11.
Defective IMTE Control
11.1 If IMTE is found to be out of calibration at any stage during the performance
of any tests or calibration, a NCR shall be raised immediately, and an
investigation shall be made as to the validity of previous inspection results
made by the suspect IMTE.
11.2 When returned from use, if the IMTE is found to be damaged and/or out of
calibration, it shall be segregated & identified.
11.3 Damaged and defective IMTE which cannot be re-calibrated shall be
disposed.
11.4 IMTE equipment when not in use, shall be kept in a dry storage area.
12.
Quality Records
The calibration records for IMTE shall be controlled in accordance with the
Quality Records Control Procedure.
