Preface
This is the harmonized CSA Group and UL standard for safety requirements for electrical equipment for measurement, control, and laboratory use – Part 2-030: Particular requirements for equipment having testing or measuring circuits. It is the second edition of CSA-C22.2 No. 61010-2-030 and the second edition of UL 61010-2-030. This edition of CSA C22.2 No. 61010-2-030 supersedes the previous edition published in 2012.
This harmonized standard is based on IEC 61010-2-030, second edition: Safety requirements for electrical equipment for measurement, control, and laboratory use – Part 2-030: Particular requirements for equipment having testing or measuring circuits, issued January 2017. IEC 61010-2-030 is copyrighted by the IEC.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope and object
This clause of Part 1 is applicable except as follows:
1.1.1 Equipment included in scope
Replacement:
Replace the text with the following:
This group safety publication is primarily intended to be used as a product safety standard for the products mentioned in the scope, but shall also be used by technical committees in the preparation of their publications for products similar to those mentioned in the scope of this standard, in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
This part of IEC 61010 specifies safety requirements for equipment having testing or measuring circuits which are connected for test or measurement purposes to devices or circuits outside the measurement equipment itself.
These include measuring circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. The existence of these circuits in equipment requires additional protective means between the circuit and an OPERATOR.
NOTE These testing and measuring circuits can, for example:
– measure voltages in circuits of other equipment
– measure temperature of a separate device via a thermocouple
– measure force on a separate device via a strain gauge
– inject a voltage onto a circuit to analyse a new design.
Equipment having these testing and measuring circuits may be intended for performing tests and measurements on hazardous conductors, including MAINS conductors and telecommunication network conductors. See Annex BB for considerations of HAZARDS involved in various tests and measurements.
