IEC 61010-2-030:2017

Overview

IEC 61010-2-030:2017 is a Part 2 particular standard in the IEC 61010 family that defines safety requirements for equipment having testing or measuring circuits. It applies to electrical test & measurement equipment, laboratory instruments and process-control devices whose measuring or testing circuits connect to external devices or circuits. This edition (2017, Edition 2.0) is a technical revision to the 2010 edition and has the status of a group safety publication under IEC Guide 104.

Key topics and technical requirements

This standard supplements IEC 61010-1 and focuses on hazards specific to measuring/testing circuits. Important technical topics include:

• Protection against electric shock for operators when testing or measuring live circuits, including additional protective means between the measuring circuit and the operator.
• Insulation, clearance and creepage distances (including specifications for wet locations and for terminals exceeding 1 000 V a.c. or 1 500 V d.c.).
• Transient overvoltage requirements, with added protections for mains-voltage measuring circuits and modified requirements for reduction of transient overvoltages.
• Indirect bonding rules for testing/measuring circuits, revised to consider duration of current flow vs body current using IEC TS 60479-1 and IEC TS 60479-2 guidance.
• Test voltages and impulse withstand values for measuring circuits (see normative tables K.102–K.104 and K.105).
• Limits for overvoltage testing: the voltage source for testing overvoltage-limiting components may be limited to 400 V under defined conditions.
• New/updated annexes: informative Annex CC (dimensions of 4 mm “banana” terminals) and Annex DD (flowchart for insulation by circuit type) plus measurement-category and insulation guidance.

Practical applications and who uses it

IEC 61010-2-030:2017 is used to design, assess and certify safety of equipment that connects test or measuring circuits to external devices. Typical users:

• Manufacturers of oscilloscopes, multimeters, insulation testers, process instrumentation and laboratory instruments.
• Product safety engineers, R&D teams and compliance officers ensuring designs meet international safety requirements.
• Test houses, certification bodies and compliance assessors who evaluate electrical safety and insulation/clearance compliance.
• Technical committees and standards writers who reference this Part 2 when developing related product standards.
