When ordering custom pneumatic probes, manufacturers will ask: “Which standards do you need to comply with?” For most buyers, the choice boils down to ISO (International Organization for Standardization) or ASME (American Society of Mechanical Engineers). Here’s how to decide.

ISO standards are your go-to for:

· Global projects: ISO 9001 (quality management) is recognized in 160+ countries, critical if your probes will be used in Europe, Asia, or multinational labs.

· Aerospace and defense: ISO 17025 ensures calibration traceability, a must for NATO or ESA contracts.

· Material consistency: ISO 13485 (medical devices) dictates biocompatible materials if probes contact bodily fluids (e.g., in medical airflow tests).

ASME standards shine for:

· U.S.-focused industries: ASME B46.1 governs surface finishes—vital for probes in high-precision U.S. automotive or energy tests.

· Pressure vessel integration: ASME BPVC (Boiler and Pressure Vessel Code) ensures probes can withstand extreme pressure in U.S. power plants.

· Aerospace specifics: AS9100 (aerospace quality) is stricter than ISO for components used in U.S. military or NASA projects.

When to require both:
For cross-border projects (e.g., a U.S. manufacturer supplying probes to a European wind tunnel), specify ISO 9001 + ASME B46.1. It covers global quality benchmarks while addressing regional precision needs.

Red flags: If a manufacturer says “we follow all standards,” push for specifics. A probe for high-temperature use should reference ISO 1217 (wind tunnel testing) or ASME PTC 19.3 (instrumentation), not vague claims.
