IEC 61010-1:2010

Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 1: General requirements

IEC 61010-1:2010 specifies general safety requirements for the following types of electrical equipment and their accessories, wherever they are intended to be used.
a) Electrical test and measurement equipment
b) Electrical industrial process-control equipment c) Electrical laboratory equipment
This third edition cancels and replaces the second edition published in 2001. It constitutes a technical revision. This edition includes the following significant changes from the second edition, as well as numerous other changes.
- The scope of the standard has been expanded to include all locations where these products may be used, so that both professional and non-professional versions of these products are within the scope.
- The requirements for testing and measuring circuits (in various subclauses and the entirety of Clause 16) have been removed and included in a particular standard IEC 61010-2-030.
- Insulation requirements (6.7) have been completely rewritten.
- Additional requirements for protection against mechanical HAZARDS (Clause 7) have been included.
- Surface temperature limits (Clause 10) have been modified to conform to the limits of EN 563.
- Radiation requirements (Clause 12) have been modified, and take into account a distinction between intended emission and unintended emission.
- Requirements for reasonably foreseeable misuse and ergonomic aspects have been added (Clause 16).
- A new clause (Clause 17) has been added to deal with HAZARDS and environments not covered by the standard, along with a new informative annex (Annex J) dealing with RISK assessment.
- A new informative annex (Annex E) addresses methods of reducing the POLLUTION DEGREE of a micro-environment.
- Requirements for the qualification of coatings for protection against POLLUTION have been added (Annex H).
- A new informative annex (Annex I) has been added to further explain how to determine the WORKING VOLTAGE of a MAINS CIRCUIT.
The contents of the corrigendum 1 of May 2011, the interpretation sheet 1 of February 2013 and the corrigendum 2 of October 2013 have been included in this copy.

SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –

Part 1: General requirements
INTERPRETATION SHEET 1
This interpretation sheet has been prepared by IEC technical committee 66: Safety of
measuring, control and laboratory equipment.
The text of this interpretation sheet is based on the following documents:
ISH Report on voting
66/497A/ISH 66/505/RVD
Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.
___________
as follows:
“The generator shall be able to supply a power of at least 500 VA.”
This has given rise to the following questions:
How does one interpret the requirement for voltage testers in 6.8.3.1 of IEC 61010-1:2010?
Specifically, this subclause requires that “The generator shall be able to supply a power of at
least 500 VA.” Does this requirement apply throughout the rated output range of the voltage
tester? What is meant by the word “generator”? Is the “generator” the power supply within the
voltage tester, or the voltage tester output, or something else?
Interpretation:
“A voltage tester used for type tests must be able to deliver at least 500 VA at its full-rated
output voltage. It does not necessarily need to deliver 500 VA if set for lower voltages.
For example, a voltage tester that can deliver 100 mA at any test output voltage up to 5 000 V
(and a current corresponding to 500 VA above 5 000 V) would meet the requirement.
The requirements for voltage testers used for routine (production line) tests are included in
Annex F. The requirements of 6.8.3.1 do not apply to these voltage testers.”
