SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
Part 2-012: Particular requirements for climatic and environmental
testing and other temperature conditioning equipment
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC

Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61010-2-012 has been prepared by IEC technical committee 66:

Safety of measuring, control and laboratory equipment.

It has the status of a group safety publication in accordance with IEC Guide 104.

This second edition cancels and replaces the first edition published in 2016. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) alignment with changes introduced by Amendment 1 of IEC 61010-1:2010;
b) changes related to the use of small capitals for defined terms only;

d) requirements for overtemperature protection in 10.101, including deletion of the second

part of the sentence in item b), and the deletion of item c);

e) changes pertaining to the accurate employment of terms "temperature", "operating

temperature", "working temperature", "application temperature", "room temperature" and

"ambient temperature" in 3.5.104, 3.5.105, 4.3.1, 4.3.2, 5.4.2, 8.2.1, 8.2.2, 11.7.2.101.2,

11.7.2.101.3, 13.2.102, 14.102, 15.101, 15.102, 15.103, Introduction and many other

locations. For the purpose of clarification, the definition of 3.5.114, CONTROLLED

TEMPERATURE, is added.

INTRODUCTION

This Part 2-012, along with Part 2-010 and Part 2-011, taken together, address the specific

HAZARDS associated with the heating and cooling of materials by equipment and are organized

as follows:

Specifically addresses the HAZARDS associated with equipment incorporating heating

IEC 61010-2-010
systems.

Specifically addresses the HAZARDS associated with equipment incorporating REFRIGERATING

IEC 61010-2-011
SYSTEMS.

Specifically addresses the HAZARDS associated with equipment incorporating both heating

and REFRIGERATING SYSTEMS that interact with each other such that the combined heating

and REFRIGERATING SYSTEM yield additional or more severe HAZARDS for the two systems

IEC 61010-2-012

than if treated separately. It also addresses the HAZARDS associated with the treatment of

materials by other factors like irradiation, excessive humidity, CO and MECHANICAL

MOVEMENT, etc.
Guidance for the application of the appropriate Part 2 standard(s)

When the equipment includes only a material heating system, and no REFRIGERATING SYSTEM

or other environmental factors apply, then Part 2-010 applies without needing Part 2-011 or

REFRIGERATING SYSTEM, and no
Part 2-012. Similarly, when the equipment includes only a

material heating system or other environmental factors apply, then Part 2-011 applies without

needing Part 2-010 or Part 2-012. However, when the equipment incorporates both a material

heating system, and a REFRIGERATING SYSTEM or the materials being treated in the intended

application introduce significant heat into the REFRIGERATING SYSTEM, a determination should

be made as to whether the interaction between the two systems will generate additional or

HAZARDS than if the systems were evaluated separately (CONTROLLED
more severe

TEMPERATURE, see flow chart for selection process). If the interaction of the heating and

cooling functions yields no additional or more severe HAZARDS, then both Part 2-010 and

Part 2-011 apply for their respective functions. Conversely, if additional or more severe

HAZARDS result from the combining of the heating and cooling functions, or if the equipment

incorporates additional material treatment factors, then Part 2-012 applies, but not Part 2-010

or Part 2-011.
What HAZARDS are applicable for a REFRIGERATING SYSTEM?

The typical HAZARDS for a REFRIGERATING SYSTEM (see Figure 101) consisting of a MOTOR-

COMPRESSOR, a CONDENSER, an expansion device and an EVAPORATOR include but are not

limited to:

– The maximum temperature of LOW-PRESSURE SIDE (return temperature) to the MOTOR-

COMPRESSOR. A MOTOR-COMPRESSOR incorporates a REFRIGERANT cooled motor and it

should be established that the maximum temperatures of the LOW-PRESSURE SIDE under

RATINGS within the motor.
least favourable condition do not exceed the insulation

– The maximum pressure of LOW-PRESSURE SIDE at the inlet to the MOTOR-COMPRESSOR. The

housing of the MOTOR-COMPRESSOR is exposed to this pressure and so the design RATING

of the MOTOR-COMPRESSOR housing should accommodate the worst-case pressures whilst

providing the correct safety margin for a pressure vessel.

– The maximum temperature of HIGH-PRESSURE SIDE to the CONDENSER. The temperatures of

the HIGH-PRESSURE SIDE under most unfavourable conditions may present a temperature

HAZARD if the OPERATOR is exposed to them or if the electrical insulation is degraded.

– The maximum pressure of HIGH-PRESSURE SIDE at the outlet to the MOTOR-COMPRESSOR.

The REFRIGERANT components downstream of the MOTOR-COMPRESSOR up to the expansion

device are exposed to this pressure and so the design RATING of these components should

accommodate the worst-case pressures whilst providing the appropriate safety margin for

a pressure vessel.
---------------------- Page: 13 ----------------------
SIST EN IEC 61675-1:2022
– 8 – IEC 61010-2-012:2019 © IEC 2019

– The maximum CONTROLLED TEMPERATURES, namely, the SOAKED TEMPERATURE CONDITIONS,

from which the heat is being extracted, may impact the maximum temperature of LOW-

PRESSURE SIDE to the MOTOR-COMPRESSOR as well as present a temperature HAZARD if the

OPERATOR is exposed to them or if the electrical insulation is degraded. Whether this

CONTROLLED TEMPERATURE is derived from an integral heating function of the device or

from the heat dissipated from the material being cooled, the impact under worst case

conditions should be evaluated.

– The current draw of the equipment should be established when including the worst-case

running conditions of the REFRIGERATING SYSTEM including any defrost cycles that may

apply.

The worst-case conditions should be determined for the equipment and will include both the

NORMAL USE conditions as well as the most unfavourable testing results under
least favourable
SINGLE FAULT CONDITIONS.

SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL AND LABORATORY USE –
Part 2-012: Particular requirements for climatic and environmental
testing and other temperature conditioning equipment
1 Scope and object
This clause of Part 1 is applicable except as follows:
1.1.1 Equipment included in scope
Replacement:
Replace the second paragraph by the following:

This part of IEC 61010 specifies safety requirements for electrical equipment and its

accessories within the categories a) through c), wherever it is intended to be used, whenever

that equipment incorporates one or more of the following characteristics:

– A REFRIGERATING SYSTEM that is acted on or impacted by an integral heating function such

that the combined heating and REFRIGERATING SYSTEM generates additional and/or more

severe HAZARDS than those for the two systems if treated separately.

– The materials being treated in the intended application introduce significant heat into the

REFRIGERATING SYSTEM, so that the REFRIGERATING SYSTEM in the application yields
additional and/or more severe HAZARDS than those for the REFRIGERATING SYSTEM if
operated at the maximum RATED ambient temperature alone.

– An irradiation function for the materials being treated presenting additional HAZARDS.

– A function to expose the materials being treated to excessive humidity, carbon dioxide,

salt mist, or other substances which can result in additional HAZARDS.
– A function of MECHANICAL MOVEMENT presenting additional HAZARDS.

– Provision for an OPERATOR to walk in to the operating area to load or unload the materials

being treated.
Addition:
Add the following text after the last paragraph:

NOTE 101 Examples of such equipment include environmental testing and plant growth TEST CHAMBERS,

refrigerating CIRCULATORS which incorporate heating, and recirculating coolers for extracting heat.

It is possible that all or part of the equipment falls within the scope of one or more other

Part 2 standards of IEC 61010 as well as within the scope of this standard. In that case, the

requirements of those other Part 2 standards also apply. This document is intended for

application when one or more of the additional HAZARDS described in the above dashed listed

items are introduced. However, when the equipment incorporates only a REFRIGERATING

SYSTEM or only a heating function or a combination of the two without introducing the

additional HAZARDS described in the above list, then IEC 61010-2-011 or IEC 61010-2-010 or

both, as appropriate, apply instead of this Part 2-012.

See further information in the flow chart (Figure 102) for selection process and guidance in

the Introduction.
