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.
CALIBRATION CERTIFICATES : ISO/IEC 17025:2005
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?
TheSANASHome Page
Select Accredited Facilities from the top menu bar
Choose Directory of Accredited Facilities from LHS Menu
Select Calibration Laboratories
A list of all accredited Calibration Laboratories will appear
The search can be refined: Select Dimensional LaboratoriesAnd then select a laboratory
