Yes. For aerospace, I’d prioritize labs that can show ISO/IEC 17025 accreditation for the specific measurement ranges you need, plus familiarity with AS9100/Nadcap, ANSI/NCSL Z540.3, NIST/SI traceability, measurement uncertainty, and audit-ready certificates.
Since you appear to be in Southern California, these are especially worth considering:
| Provider | Dimensional | Pressure | Aerospace fit | Location |
|---|---|---|---|---|
| Transcat | ✅ | ✅ | Excellent — aerospace/aviation support; ISO/IEC 17025 |

1. American Gage — best aerospace-specific choice
American Gage explicitly supports aerospace/defense customers and lists AS9100, Nadcap/AMS 2750, ANSI/NCSL Z540.3 and DoD supplier requirements. Its A2LA ISO/IEC 17025:2017 scope includes dimensional and pressure, including gage blocks, thread/ring/plug gauges, micrometers, calipers, indicators, pressure gauges and transducers. It also offers LA County pickup routes.
2. Transcat — best broad-capability option
Transcat's Fullerton lab is ISO/IEC 17025:2017 accredited and specifically lists pressure, dimensional, force, torque and CMM/GD&T capabilities. Transcat also has specialized pressure calibration and aerospace/aviation support, making it a good choice if your instrument list is large and diverse.
3. Precision Labs — particularly attractive for Antelope Valley aerospace
Precision Labs in Palmdale is ISO/IEC 17025:2017 accredited and has capabilities spanning dimensional, pressure, force, mass, flow, electrical and other physical measurements. Its location makes it particularly convenient for aerospace operations around Palmdale/Edwards AFB.
For aerospace procurement, don't just ask “Are you ISO 17025 accredited?” Ask the lab to confirm that your exact instrument, range, test points, and uncertainty are within its accredited scope. I'd also request:
For example, American Gage specifically describes aerospace certificates containing as-found/as-left data, uncertainty, traceability and decision rules, which is the sort of documentation I'd look for in an aerospace supplier.
If you give me the specific tools and ranges (e.g., micrometers 0–6", pressure transducers 0–5,000 psi), I can narrow this to the 3–5 labs whose accredited scopes are most likely to cover your equipment, including turnaround and local pickup options.
