American Gage holds ISO/IEC 17025:2017 accreditation through A2LA (American Association for Laboratory Accreditation), certificate number 0086.01, plus compliance with ANSI/NCSL Z540.3-2006 and NIST traceability on every measurement. Call (657) 216-2600.
Calibration accreditation is the foundation that lets a calibration certificate hold up to audit. When an FDA inspector reviews a 21 CFR Part 211 records package, when a notified-body auditor reviews an ISO 13485 supplier qualification, when an AS9100 customer-quality reviewer checks calibration evidence for a Nadcap-flagged process — what they look for is the accreditation that the issuing lab operates under.
American Gage's accreditation portfolio is below. The full A2LA scope of accreditation PDF is downloadable for inclusion in supplier-qualification packets.
ISO/IEC 17025:2017 — A2LA accredited
Accreditation body: A2LA — the American Association for Laboratory Accreditation.
Certificate number: 0086.01
Standard: ISO/IEC 17025:2017
Scope: dimensional, electrical, mass, mechanical, pressure and flow, temperature and humidity, pipette.
ISO/IEC 17025:2017 is the international standard for the competence of calibration and testing laboratories. An accredited lab has demonstrated to an independent accreditation body — in our case, A2LA — that it operates a documented quality system, uses traceable measurement standards, calculates measurement uncertainty correctly, and produces calibration certificates that meet international expectations. For most regulated work — aerospace AS9100, medical device ISO 13485, automotive IATF 16949, pharma FDA 21 CFR — ISO 17025 accreditation is the qualifying evidence the calibration supplier has to bring.

ANSI/NCSL Z540 compliance
American Gage operates compliant with both editions of the ANSI/NCSL Z540 series:
- ANSI/NCSL Z540-1-1994 — “Calibration Laboratories and Measuring and Test Equipment — General Requirements.”
- ANSI/NCSL Z540.3-2006 — “Requirements for the Calibration of Measuring and Test Equipment” — including the documented decision rule and test uncertainty ratio (TUR) that DoD primes, defense contractors, and most aerospace customers require on every calibration certificate.
Every calibration certificate American Gage issues documents the TUR and the decision rule applied, supporting the false-accept risk analysis Z540.3-compliant customers run on incoming calibration evidence.
NIST traceability
NIST traceability means that every measurement American Gage issues connects, through an unbroken chain of calibrations, to a U.S. national standard at the National Institute of Standards and Technology. The chain has stated uncertainty at each link, the chain is documented on every calibration certificate, and the chain is what makes American Gage's calibration evidence acceptable to FDA, AS9100, ISO 13485, and Z540.3-driven audits worldwide.
What our customers receive on every certificate
An American Gage calibration certificate documents:
- Customer instrument identification — manufacturer, model, serial, asset tag if provided
- As-found readings before any adjustment
- As-left readings after calibration or adjustment
- Measurement uncertainty calculated to the appropriate methodology (GUM, ISO 8655-7 for pipette, ISO 17025 5.10.4 for other disciplines)
- The reference standards used and their NIST traceability chain
- Environmental conditions during calibration
- Technician identity
- Calibration date plus recommended due date
- The decision rule applied per ANSI/NCSL Z540.3-2006, with TUR documented
This format supports FDA inspection (21 CFR Part 211, Part 820, Part 11-compatible PDF), AS9100 customer-quality audits, ISO 13485 notified-body audits, Nadcap pyrometry reviews, IATF 16949 supplier-qualification audits, and DoD prime/defense contractor calibration reviews.
Supplier qualification packets
The standard supplier-qualification packet American Gage sends includes:
- Current A2LA scope of accreditation

For ISO 13485, AS9100, IATF 16949, and FDA-driven supplier qualifications, send the template your procurement team uses and we fill and return.
Frequently asked questions
How often is the A2LA accreditation renewed?
A2LA accreditation is renewed on a 1-2 year cycle through an on-site assessment by an A2LA-assigned assessor. Each renewal updates the scope of accreditation to reflect current measurement capabilities.
Where can I get the latest A2LA scope of accreditation PDF?
Direct link to the current scope PDF. The link points to A2LA's public directory and always reflects the current revision.
Does ISO/IEC 17025:2017 accreditation replace ISO 9001?
No — they cover different scopes. ISO 9001 is a general quality management standard. ISO 17025 is calibration-laboratory-specific competence accreditation. Most ISO 13485 and AS9100 customers ask for both. An ISO 9001 customer letter is available on request.
Is American Gage on the approved supplier list for [specific aerospace prime or medical device manufacturer]?
American Gage is an external calibration supplier to a wide range of AS9100, ISO 13485, and IATF 16949 manufacturers across Southern California. Whether American Gage is on a specific customer's approved supplier list depends on that customer's qualification process — most rely on our A2LA scope as the qualifying evidence. Supplier-qualification packets available on request.
What measurement uncertainty does American Gage achieve at the lowest level?
It varies by discipline and measurement point. The scope PDF documents specific uncertainty at each measurement. Headline examples: relative humidity to 0.32% RH via RH Systems 473-RP2 chilled mirror; Class 1 mass up to 25 kg; temperature scope −200 to 660 °C.
