Calibration Program
1.0 Objective
1.1. This sample calibration procedure defines the calibration program requirements for all
Measurement and Test Equipment.
2.0 Scope
2.1. Measurement and Test Equipment are those devices used to test, measure, evaluate, inspect,
or otherwise examine materials, supplies, equipment, and systems, or to determine compliance
with specifications.
2.2. This also includes process control devices with the potential to impact product quality.
2.3. This procedure shall provide instructions for the management of calibrations performed on
Measurement and Test Instruments by third party contractors.
3.0 Responsibility
3.1. Measurement and Test Equipment User
3.1.1. It is the equipment user’s responsibility to verify that the Measurement and Test Equipment is
in calibration by checking the label(s) before use.
3.1.2. It is the equipment user’s responsibility to return Measurement and Test Equipment, if
portable, to the Calibration Coordinator (QA/Maintenance Personnel) before the calibration due
date expires.
3.1.3. It is the equipment user’s responsibility to alert the Calibration Coordinator if Measurement
and Test Equipment requires new batteries.
3.1.4. It is the equipment user’s responsibility to alert the Calibration Coordinator if Measurement
and Test Equipment is not functioning correctly.
3.2 Calibration Co-Ordinator (QA/Maintenance Personnel)
3.2.1. Shall evaluate and document Calibration Intervals on an annual basis.
3.2.2. Shall publish the calibration status report monthly.
3.2.3. Shall update the Calibration records.
4.0 Procedure
4.1 Enrolment of Equipment in the Calibration Program
4.1.1 The Requester will notify the Calibration Co-Ordinator of new equipment.
The Requester shall deliver the following to the Calibration Coordinator:
4.1.2 Measuring equipment (if portable)
A copy of the equipment specifications

4.2 Calibration Intervals
4.2.1 All calibration certificate should be renewed yearly or after any modification on the
equipment.
4.3 Discontinued / Disposed Equipment
4.3.1 The Calibration ID label will be removed from the equipment by the Owning Department and
affixed to the Measurement instrument Status Change Form.
4.3.2 The equipment shall be appropriately identified for disposal/destruction by the Owning
Department.
4.3.3 The Owning Department will obtain approval for disposal of asset.
4.4 Calibration Database and Reporting
4.4.1 QA / Engineering / Document Control shall maintain records for tracking and controlling
Measurement and Test Equipment which will prevent the use of expired or unfit Measurement and
Test Equipment.
4.4.2 The Calibration record shall outline the calibration method, in the comments section of the
equipment history record:
4.4.3 Sub-Contract On-Site calibration. (Performed on-site by approved supplier).
4.4.4 The Calibration Co-Ordinator will issue a calibration status report once every month to the
Product Department Supervisors, Department Calibration Representatives, the Quality Assurance
Manager and the Production Manager.
4.4.5 Monthly calibration status report shall consist of:
4.4.6 Equipment DUE for calibration in the next 30 days.
4.4.7 Equipment OVERDUE.
4.4.7 Equipment On-Hand.
4.4.9 Remedial/Corrective Action Form status.
4.5 Labelling, Identification and Storage
4.5.1 A Calibration label must be attached to, or be posted within visual range of, the Measurement
and Test Equipment.
4.5.2 Calibrated Measurement and Test Equipment shall be marked with a label to display:
4.5.3 The date of the most recent calibration.
4.5.4 The date when the next calibration is scheduled.
4.5.5 The initials of personnel or sub-contractor who performed the calibration or the name of the
sub-contractor.

Calibration Program
4.5.6 Calibration Seals shall be affixed to Measurement and Test Equipment where a possibility of
alteration to calibrated settings could occur. A tamperproof seal is affixed to the setting adjustment
area and or access screw, this acts to safeguard against any internal and or external adjustments
that could invalidate the calibration settings.
4.6 Calibration Procedures
4.6.1 Calibration procedures must be application specific and prescribe step-by-step instructions
for calibration of Measurement and Test Equipment or categories thereof. These shall be prepared
internally, by another agency, the manufacturer or a composite of any of these.
4.6.2 Calibration procedures must state: the acceptable limits of accuracy and precision;
standards required; and sufficient information to enable qualified personnel to perform the
calibration.
4.6.3 Equipment used for Calibration(s) shall have a Test Accuracy Ratio (TAR) of at least 10:1, i.e.
Calibration Equipment uncertainty will be 10 times greater than the uncertainty of the
Measurement and Test Equipment being calibrated, rationale for exceptions must be documented
and approved. Rational may include an increase to the calibration frequency to compensate for this
lack of compliance.
4.6.4 Calibration procedures and internal calibration records must state; “Calibration performed by
trained personnel only”.
4.7 Calibration – External
4.7.1 Calibration Method
4.7.1.1 Calibration performed by Contractors shall be conducted by approved Suppliers.
4.7.1.2 The methods and criteria used to perform calibration of Measurement and Test Equipment
shall comply with the manufacturers specification and shall be traceable, through certification.
4.7.1.3 Method of Calibration for linear Measurement Instruments such as External Micrometers,
Vernier Calipers and Dial Gauges may use the methodology outlined in the British Standards in
Engineering Metrology.
4.7.1.4 Special instructions for calibration shall be detailed in the Test Equipment Installation
Qualification Form, where applicable.
