Overview
EN IEC 62037-2:2021/A1:2026 (Amendment 1) is an update to the international standard for measuring passive intermodulation (PIM) in coaxial cable assemblies. It clarifies test methods and reporting requirements for PIM measurement on coaxial cables and connectors, with specific focus on per-end testing and per‑cable testing in multi‑channel assemblies. The amendment was prepared by IEC TC 46 (Cables, wires, waveguides, RF connectors and passive components) and addresses electromagnetic compatibility aspects of passive RF and microwave components.
Key topics and technical requirements
- Test scope: Measurement of passive intermodulation in coaxial cable assemblies and associated connectors.
- Per‑end and per‑cable testing: Tests shall be performed independently on each end and on each individual cable in a multi‑channel assembly.
- Connector compliance: Connectors used in the test must meet their specification when subjected to the impact test specified in IEC 62037-3.
- Mechanical stress considerations:
- Test set-up and cable movement are illustrated (example figures referenced in the amendment).
- The bending radius (r) is tied to the cable’s nominal outside diameter (ø).
- The distance parameter (d) is related to cable flexibility and the specified repeated bending radius; default calculation rules apply where not otherwise specified.
- Measurement procedure:
- Record the maximum PIM level before applying mechanical stress.
- Apply mechanical stress/rotation as specified.
- Record the maximum PIM level after applying mechanical stress.
- Reporting requirements: For each individual cable in the assembly the report shall include:
- Maximum PIM levels prior to rotation,
- Maximum PIM levels during rotation,
- Maximum PIM levels after rotation.
Practical applications and users
This amendment is directly useful for:
- Manufacturers of coaxial cable assemblies, RF connectors and passive microwave components - to validate product PIM performance and compliance.
- Independent and in‑house test laboratories that perform PIM testing and produce compliance reports.
- RF systems integrators, installers and site acceptance engineers who need to verify low‑PIM performance for base stations, DAS (Distributed Antenna Systems), and critical RF links.
- Procurement and compliance teams specifying PIM measurement criteria for supplier acceptance.
Benefits include improved repeatability of PIM tests, clearer per‑cable pass/fail criteria for multi‑channel assemblies, and harmonized reporting for acceptance and troubleshooting.
