Standards & Accreditation

When Is ISO/IEC 17025 Calibration Recommended?

ISO/IEC 17025 calibration is recommended whenever a company needs traceable and internationally recognized results for internal quality systems, customer requirements, regulated industries or scheduled verification programs. It is particularly useful after machine relocation, service intervention, repairs, adjustments or whenever testing reliability must be confirmed through accredited certification.

What do ISO/IEC 17025, ANAB and ILAC-MRA mean?

ISO/IEC 17025

ISO/IEC 17025 is the international standard that defines the general requirements for the competence, impartiality and consistent operation of testing and calibration laboratories.

ANAB

ANAB (ANSI National Accreditation Board) is the accreditation body that assesses laboratories against this standard and grants accreditation when the required criteria are met.

ILAC-MRA

ILAC-MRA is the International Laboratory Accreditation Cooperation Mutual Recognition Arrangement, an international agreement among accreditation bodies that supports the global acceptance of accredited calibration and testing results.

ATI accreditation

Because ANAB is an ILAC-MRA signatory for ISO/IEC 17025 accreditation, certificates issued under ANAB accreditation are internationally recognized within the same framework as certificates issued by other national accreditation bodies that are signatories to the same arrangement, such as ACCREDIA in Italy, DAkkS in Germany and UKAS in the United Kingdom.

Which Standards Is ATI Accredited For?

ATI accreditation covers a broad range of calibration services for hardness testers, material testing machines, dimensional instruments and precision equipment. The following standards define the technical requirements against which our calibrations are performed and certified.

Hardness Testing
ASTM E18 and ISO 6508-2 for Rockwell hardness · ASTM E10 and ISO 6506-2 for Brinell hardness · ASTM E92, ASTM E384 and ISO 6507-2 for Vickers hardness · ISO 4545-2 for Knoop hardness · ASTM A956 and ISO 16859-2 for Leeb hardness · ASTM D2240 and ISO 21509 for Shore durometer hardness · ASTM E3246 and DIN 50157 for differential indentation hardness
Reference Test Blocks
ASTM E18 and ISO 6508-3 for Rockwell reference blocks · ASTM E10 and ISO 6506-3 for Brinell reference blocks · ASTM E92, ASTM E384 and ISO 6507-3 for Vickers and Knoop reference blocks
Material Testing Machines
ASTM E4 and ISO 7500-1 for force verification of tension and compression machines · ASTM E2428, ASTM E2624, ISO 6789-2 and DIN 51309 for torque machines
Dimensional and Displacement
ASTM E2658 and ASTM E2309 for displacement and speed of material testing machines · ASTM E83 and ISO 9513 for extensometers · ASME B89.1.14 for calipers · ASTM E1951 for microscope reticle and stage micrometer calibration
Time
Stopwatch calibration by comparison to NRC Time Signal
