Overview
SIST EN IEC 62037-2:2022/A1:2026 is a European standard amendment developed by the Slovenski inštitut za standardizacijo (SIST) and aligned with IEC 62037-2:2021/AMD1:2025. This standard focuses on measuring passive intermodulation (PIM) in coaxial cable assemblies within passive RF (radio frequency) and microwave devices. The amendment addresses test procedures, reporting requirements, and clarifies standards for evaluating coaxial cables used in high-frequency and microwave applications. Manufacturers, engineers, and testing laboratories can benefit from applying this standard to ensure reliable, high-performance coaxial cable assemblies and maintain compliance with international standards.
Key Topics
- Passive Intermodulation (PIM) Measurement: The standard provides methods to evaluate and report PIM levels in coaxial cable assemblies, crucial for detecting nonlinearities in passive RF components that could degrade system performance.
- Revised Test Procedures: Clarifies that tests are to be performed on each individual cable and each end of every cable within multi-channel assemblies, increasing reliability and repeatability in PIM measurements.
- Connector and Cable Requirements: Specifies that connectors and cables must comply with relevant specifications and undergo impact testing as per referenced IEC standards.
- PIM Level Reporting: Updates the requirements to record and report maximum PIM levels-before, during, and after mechanical stress (such as rotation or bending)-for every cable in the assembly.
- Standardized Test Conditions: Provides updated guidance on test parameters, such as bending radii and distances related to the flexibility of cables, tied directly to the physical specifications of the assemblies under test.
Applications
Adhering to SIST EN IEC 62037-2:2022/A1:2026 provides clear, practical benefits for a range of stakeholders in the RF and microwave sector:
- Telecommunications Infrastructure: Measurement of passive intermodulation in coaxial cable assemblies is vital in cellular base stations, distributed antenna systems (DAS), and broadband networks where signal purity is critical.
- RF Manufacturing and Quality Control: RF cable and connector manufacturers utilize these procedures to qualify products and ensure they meet specified PIM performance, thereby reducing the risk of costly field failures.
- Test Laboratories: Accredited laboratories performing RF compliance and reliability testing rely on these detailed procedures to generate quality, reproducible data and conformance reports for clients.
- Network Operators: By setting clear criteria for PIM testing and reporting, the standard helps network operators assess the suitability of coaxial cable assemblies in maintaining high-quality signal transmission.
Related Standards
For comprehensive RF system performance and compatibility, consider these interconnected standards:
- IEC 62037 Series: Addresses passive intermodulation measurement for a variety of passive RF and microwave components.
- IEC 60068: Relates to environmental testing, including vibration, shock, and mechanical stress, which correlate with the stress conditions evaluated in PIM testing.
- EN IEC 62037-2:2021: The base European standard for passive intermodulation measurement in coaxial cable assemblies, to which this amendment applies.
- IEC Standards for RF Connectors (ICS 33.120.30): Provide detailed construction and test requirements for connectors used in RF applications.
- IEC 620373: Specifies impact test methods for connectors referenced within the amended procedures.
Following SIST EN IEC 62037-2:2022/A1:2026 ensures harmonization with recognized international best practices, enhancing the performance, quality, and reliability of coaxial cable assemblies in advanced RF and microwave systems.
