Overview

EN IEC 61326-2-1:2021 (CLC adoption of IEC 61326-2-1:2020) defines EMC requirements for sensitive test and measurement equipment used in EMC unprotected applications. It is a particular-part standard that must be used together with IEC 61326-1:2020 (general requirements). The document specifies detailed test configurations, operational conditions and performance criteria for equipment whose test and measurement circuits (internal and/or external) are intentionally not EMC protected for functional reasons.

Key topics and requirements

• Scope and applicability: Targets equipment such as oscilloscopes, spectrum analysers, network analysers, logic analysers, digital multimeters and board test systems - i.e., devices with exposed test/measurement ports.
• EMC test plan: Guidance on preparing an EMC test plan in line with IEC 61326-1, with additional detail for sensitive, unprotected instruments.
• Configuration of EUT during testing: Rules for how the equipment under test (EUT) is arranged, including the handling of I/O ports - e.g., covering and terminating test input ports with appropriate impedances unless that prevents realistic measurement.
• Operational conditions: Defines required operating modes and signal conditions during immunity and emission testing so performance is assessed in representative use states.
• Performance criteria: Specifies functional performance levels and acceptance criteria to determine pass/fail under immunity or emission stress.
• Immunity and emissions: Adds particular immunity test requirements and emission considerations specific to sensitive, unshielded test instruments.
• Annexes:
  • Annex A (normative): Immunity test requirements for portable test and measurement equipment powered by battery or the circuit under test.
  • Annex B (informative): Guidance for analysis and assessment of electromagnetic compatibility.

Practical applications and users

Who uses EN IEC 61326-2-1:2021:

• Manufacturers of test and measurement instruments - to define intended environment, select test levels and demonstrate EMC behavior for unprotected ports.
• Compliance and EMC engineers - to develop test plans, set up test configurations and interpret performance criteria.
• Test laboratories - as a reference for conducting immunity and emission testing on sensitive equipment.
• R&D and QA teams - for designing instruments with predictable EMC performance when shielding is not feasible.

Practical value:

• Ensures consistent, repeatable EMC testing of sensitive measurement equipment.
• Helps manufacturers declare suitable operating environments and compliance evidence.
• Reduces risk of measurement errors or device malfunction in real-world installations.
