Traceability:

What is traceability?

• Competent transfer of traceability from a Standard to the device under

test.

CALIBRATION CERTIFICATES : ISO/IEC 17025:2005

Traceability:

How do you evaluate traceability?

• Was a recognized method used to perform the calibration?

• Was the calibration performed by an individual who has been trained and

found competent to perform the calibration?

CALIBRATION CERTIFICATES : ISO/IEC 17025:2005

Traceability:

How do you evaluate traceability?

• Was the ‘standard’ used in the calibration traceable through an

unbroken chain of calibrations to the SI system of units?

• Has the uncertainty of measurement been estimated, and stated on the

certificate?

CALIBRATION CERTIFICATES : ISO/IEC 17025:2005

Purpose:

The purpose a calibration certificate is to provide pertinent information to the

user about:

• The identity and information about the laboratory performing the

Calibration (Name, and Address and the location where the calibration was

carried out)

CALIBRATION CERTIFICATES : ISO/IEC 17025:2005

Purpose:

• Identification of the method used to perform the calibration (Own method, International Standard, Manufacturers

recommended procedure)

• Identification of the device calibrated

• The measurement results,

CALIBRATION CERTIFICATES : ISO/IEC 17025:2005

Purpose:

• Identification and signature of persons authorizing the certificate,

• (If requested) a statement that the complies with specification.

• The environmental conditions,

• The uncertainty of measurement,

• Evidence of the traceability.

What to look for:

• If the certificate does not include the SANAS logo (or a statement that the laboratory is accredited by SANAS)

along with the accreditation number of the laboratory then the certificate

has not been issued in terms of their accreditation.

Contract Review:

How do you choose a Calibration Service provider:

Are they accredited?

Are they accredited for the specific measurements and applicable range?

Is the Laboratories Measurement Capability (BMC) satisfactory for your purposes?

Are you discussing YOUR requirements with the laboratory or are they telling you what YOU want?
