Description (English):

IEC 61326-2-2:2020 specifies more detailed test configurations, operational conditions and performance criteria for equipment covered by Annex A of IEC 61326-1:2020 which is: - used for testing, measuring or monitoring of protective measures in low-voltage distribution systems, and; - powered by battery and/or from the circuit measured, and - portable. Examples of such EUTs include, but are not limited to, voltage detectors, insulation testers, earth continuity testers, earth resistance testers, leakage current clamps, loop impedance testers, “residual-current-device-testers” (RCD-testers) and phase sequence testers as defined in IEC 61557 (all parts).

Abstract

Overview

IEC 61326-2-2:2020 is a part-specific IEC standard that defines detailed EMC requirements for portable testing, measuring and monitoring equipment used in low-voltage distribution systems. It is intended to be used in conjunction with IEC 61326-1:2020 (general requirements) and specifies test configurations, operational conditions and performance criteria for battery-powered and/or circuit-powered portable equipment such as voltage detectors, insulation testers, earth continuity and resistance testers, leakage current clamps, loop impedance and RCD-testers, and phase sequence testers (examples aligned with IEC 61557).

Key topics and technical requirements

Scope and applicability: Focuses on portable equipment used for testing protective measures in LV distribution systems and powered by battery and/or the measured circuit.
EMC test plan: Guidance on test arrangement, documentation and the EMC test plan aligned with IEC 61326-1.
EUT configuration during testing:
- Connect test and measurement ports using recommended or typical leads.
- For RF immunity (IEC 61000-4-3) test setups, leads should be arranged horizontally 0.1 m apart; leads longer than 1 m should be bundled so the test object is 1 m from the EUT.
- Voltage measurement test object example: 1 000 Ω ± 100 Ω resistor in series with a test lead.
- Current measurement test object example: 100 Ω ± 10 Ω resistor in parallel with test leads.
Operational conditions: Equipment shall be tested in the most sensitive ranges or combinations of ranges; each multifunctional function is tested separately.
Immunity and emissions: Defines immunity test conditions, performance criteria and emission requirements specific to portable LV testing equipment.
Test reporting and instructions: Requirements for test results, test reports and manufacturer instructions relevant to EMC behaviour.

Practical applications - who uses this standard

Manufacturers and designers of portable electrical test equipment to ensure EMC compliance and product robustness in the field.
Test laboratories and certification bodies performing immunity and emission testing for LV distribution test instruments.
Utilities, installers and maintenance engineers seeking assurance that their handheld/measuring tools are reliable under electromagnetic disturbances.
Compliance engineers preparing EMC test plans, reports and user instructions for market entry.
