5. RESPONSIBILITIES The QA/QC Manager is responsible for monitoring and implementing the following activities:  Establishing the calibration schedule for all equipment included in the system.  Keeping a record of all calibrated instruments.  Ensuring that instruments are calibrated at all times during the work.  Storage of calibration instruments, which are defined as secondary "MASTER". Master instruments are generally stored in a locked-up cabinet under the control of the QA/QC Manager. Particularly, over-sized instruments shall be kept at adequate areas and/or in proper containers. The above mentioned activities shall be carried on by the QA/QC Department together with the department that uses the instrument.

6. PROCEDURE 6.1.

GENERAL REQUIREMENTS

Instruments and/or devices having appropriate calibration certificates can be utilised within the expiry period. After the expiry dates, the calibration of these instruments and/or devices should be calibrated. The present procedure is applicable to instruments that require to be calibrated periodically, such as pressure gages, hardness testers, paint thickness gages, optical measurement devices, etc. Calibration intervals for these instruments and/or devices are given in Attachment 1 according to T.4.096.674 Calibration of Testing and Measuring Tools and Equipment.

6.2.

IDENTIFICATION OF INSTRUMENTS

Each instrument that is subject to calibration shall be identified by a serial number. a)

This serial number will be placed on the instrument by such means that shall provide durable identification. All inspection, measuring and test instruments with missing or illegible serial numbers shall be re-calibrated prior to their use.

b)

All inspection, measuring and test instruments that are employed for the inspection or acceptance of the construction work shall be marked with utilising stickers or tags, which shall enable immediate visual confirmation of its calibration status.

CALIBRATION OF INSTRUMENTS

Instruments subject to calibration shall be calibrated on the following occasions:

6.3.1.

Periodic Calibration

This calibration will be carried out before the defined expiry dates by the QA/QC personnel or by a calibration service or agency under the control of the QA/QC Department.

6.3.2.

Re-calibration

The instruments may be re-calibrated at any time before the expiry date of the calibration if there are doubts as to the accuracy of the equipment.

6.4.

PRECISION OF CALIBRATION

The precision of the calibration shall be defined by the QA/QC Department in accordance with the class of precision stated by the manufacturer of the instrument.

6.5.

METHOD OF CALIBRATION

The calibration of the devices shall be carried out according to the manufacturer instructions. In case of the calibration procedure and/or instruction of the device manufacturer is not available, then one of the following procedures shall apply: a)

Calibration against MASTER devices, Master devices shall possess the manufacturer’s certificates. All primary "MASTER" instruments (2nd level) shall undergo calibration at predetermined periods depending on their characteristics and tendency to lose calibration. Secondary instruments (3rd level) shall be calibrated by comparison with the Masters.

b)

Calibration Control by direct measurement, Where and when applicable, the measuring devices shall be calibrated by direct measurement with appropriate and acceptable measuring methods. Measurements shall be carried out with certified devices. During the controls, if the device has calibration means, then it will be calibrated, supported with an appropriate measurement record.

c)

Calibration by an authorised institute, Calibration of the sophisticated devices, including optical measuring devices shall only be carried out by an authorised institute.

DOCUMENTATION OF CALIBRATION

A "control list" will be compiled for the measuring and test equipment and shall give the relevant data. The calibration label (Attachment 2) of the calibrated equipment shall indicate the acceptance of the calibration. When this labelling is neither practical nor considered essential for the control purposes, other procedures shall be established to ensure the conformity with this requirement. Any other procedure shall be in compliance with the requirements of related specifications and subject to approval. Prior to use of any inspection, measuring and test instrument for the construction work, the responsible engineer shall assure that the effective calibration period of the device has not yet expired and the instrument has not been damaged to a visible degree.
