INTRODUCTION

WHAT IS CALIBRATION ?

• Calibration is set of operations that establish, under specified conditions, the

relationship between values of quantities indicated by a measuring instrument or

measuring system (Inspection, Measurement and Test Equipment-IMTE) , or values

represented by a material measure or a reference material, and the corresponding

values realized by standards.

• The goal of calibration is to guarantee the accuracy of the measurements which

are done by measuring and monitoring instruments (IMTE) that affect the

comformity of measurements, in accordance with ISO/TS management standards.

Calibration

Chief Engineering

ERDEMIR CALIBRATION CENTER

• ERDEMIR Calibration Center (ECC) started its operations in mid’s 1997.

• Primarily, Calibration Center makes periodic calibrations of 6300 IMTE which are in

Erdemir’s calibration inventory,

• ECC has been accredited on November 18, 2013 related TS EN ISO / IEC 17025:

2012 standard.

• All calibrations are traceable to international standards.

• Under ECC, there are five laboratories; these are Electronic, Temperature,

Dimensional, Pressure and Gas laboratories.

• All laboratories are dust, temperature and humidity controlled.

• Air conditioning of laboratories are maintained by separately established computer-

controlled air-conditioning plants.

MISSION OF ECC

To realize periodic traceable calibrations of IMTEs that affect quality in ERDEMIR

in accordance with the Quality Management Systems and if there is no calibration

ability in Erdemir then to have them calibrated other firms.

1. ERDEMIR internal calibration services cover ;

By using general calibration procedures and related systems /

calibration work instructions,

• Adding IMTEs into inventory,

• Removing from inventory,

• Programming of calibrations ,

• Re-call for calibration,

• Calibrations of IMTEs,

• According to outcomes of calibration, evaluation of comformity and

certification labels of IMTEs

ERDEMIR external calibration services cover ;

providing calibration services in charge made, as demand,

to ERDEMIR’s subsidiaries ( ISDEMIR, CELBOR, STEEL SERVICE,

ERENCO),

to ERDEMIR’s suppliers (Companies doing business with Erdemir),

and to third parties.

Organizing calibration services that are available from

outside ERDEMIR .

• 42 units ECC calibrators (for monitoring),

• 57 units IMTEs that there is no calibration ability in ECC

(withdrawal/hardness/impact test machines, radiation

measuring instruments, etc.)

Calibration

ECC OPERATIONS

In ERDEMIR,

• 139 units IMTEs that are calibrated or to have these IMTEs calibrated by

Electronic Automation Maintenance teams,

• to have 6 units IMTEs calibrated by Auxiliary Operations and

Environment Management Department

are programmed to be calibrated and tracking of reporting operations.

GENERAL INTRODUCTION

Erdemir Calibration Laboratories consist of five separate

laboratories below,

- Dimensional,

- Electronic,

- Temperature,

- Pressure,

- Gas Detector

and a production department.

All calibration areas are environmental controlled. (temperature, humidity and

particles)

Each calibration area has its specific min-max limitations of temperature and

humidity.

Calibration is not made when these limitations are gone beyond.

Calibration

Chief Engineering

PRODUCTION CONTROL CENTER

Registration, acceptance and post-delivery operations of equipments that are brought

to our laboratories for calibration are all carried out in production control center.

Instrument / reference material types to be calibrated;

- Micrometer, Micrometer Setting Rod, Caliper, Dial indicator, Bore Gauge.

-Height gage, Feeler gauge, Steel Rule ,

-Tape Measure, Steel gauge.

- Steel Square, proctactor, precision level.

- Balance, Mass.

- Torque wrench.

Calibration Environment working conditions ;

* Relative Humidity % 45±25 RH and Temperature 20 ± 1°C .

* Limit value of particles number larger than 5 µm in 1 feet 3 volume is 700.
