Automatic electrical controls for household and similar use - Part 1: General requirements

IEC 60703-1:2010 applies to automatic electrical controls for use in, on, or in association with equipment for household and similar use, including controls for heating, air conditioning and similar applications. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof. This standard also applies to the inherent safety; to the operating values, operating times, and operating sequences where such are associated with equipment safety, and to the testing of automatic electrical control devices used in, or in association with, household or similar equipment. This standard is also applicable to controls for appliances within the scope of IEC 60335-1 as well as controls for building automation systems within the scope of ISO 16484-2. The principal changes in this edition as compared to the previous edition are as follows:
- changes to the low temperature test requirements for in-line cords;
- revision to the pollution degree for the environment surronding contacts;
- addition of the use of screwless terminals on printed circuit boards and revisions to creepage distances;
- additions of CISPR 11 EMC requirements;
- incorporation of EMC test levels from IEC 60335 series;
- additional testing for flexible cords;
- revisions to the requirements for resistance to heat, fire and tracking including replacement of clause 21 and Annexes F and G;
- new Annex T for additional requirements for non-SELV supplied sensor cable or cord;
- new requirements in H.27.1 for first and second fault approach to ensure functional safety;
- incorporation of software techniques from IEC 61508-3 in H.11.12;
- replacement of Annex D (Canada and USA) with reference to UL 746C;
- updates to the references and bibliography;
- the keyword index was deleted.

Foreword

The text of the International Standard IEC 60730-1:2010, prepared by IEC/TC 72, Automatic controls for

household use, together with the common modifications prepared by the Technical Committee CENELEC

TC 72, Automatic controls for household use, was submitted to the CENELEC Unique Acceptance

Procedure and approved by CENELEC as EN 60730-1:2011.

This document supersedes EN 60730-1:2000 + corr. Aug.2007 + A12:2003 + A1:2004 + A13:2004 +

A14:2005 + A16:2007 + corr. Mar.2010 + A2:2008.

The main technical modifications of this European Standard since the above previous edition are listed

below:
– changes to the low temperature test requirements for in-line cords;
– revision to the pollution degree for the environment surrounding contacts;

– addition to the use of screwless terminals on printed circuit boards and revisions to creepage

distances;
– additions of EN 55011 EMC requirements;
– incorporation of EMC test levels from EN 60335 series;
– additional testing for flexible cords;

– revisions to the requirements for resistance to heat, fire and tracking including replacement of

Clause 21 and Annexes F and G;

– new requirements in H.27.1 for first and second fault approach to ensure functional safety;

– incorporation of software techniques from EN 61508-3 in H.11.12;
– updates to the references and bibliography;

– the keyword index was deleted as unnecessary due to the availability of search functions for

electronic editions of the standard.

Additionally, this European Standard is the editorial result of the combined texts of EN 60730-1:2000 and

its amendments, except where CENELEC common modifications have already been incorporated in

IEC 60730-1:2010, together with the deletion of additional ‘in some countries’ paragraphs and ‘under

consideration’ paragraphs which have been introduced in IEC 60730-1:2010.
The following dates are fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-10-24
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) – *

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent

rights.

* Justification for no dow:

This European Standard replaces EN 60730-1:2000 and its amendments. However, EN 60730-1:2000

remains valid until all the Part 2’s which are used in conjunction with it have been withdrawn. No date of

withdrawal (dow) has been given pending the updating of all the Part 2's to align with this

EN 60730-1:2011. The applicable date of withdrawal is given in each Part 2. It is intended the dow for this

Part 1 will be fixed once all the Part 2's have been updated.

This Part 1 is to be used in conjunction with the appropriate Part 2 for a particular type of control, or for

controls for particular applications. This Part 1 may also be applied, so far as reasonable, to controls not

mentioned in a Part 2, and to controls designed on new principles, in which case additional requirements

may be necessary.

Subclauses which are additional to those in IEC 60730-1:2010 are numbered 601, 602 etc. Annexes

which are additional to those in IEC 60730-1:2010 are prefixed “Z”.

Where reference is made to other international or harmonized standards, the edition of that standard

quoted in Annex ZA (normative) is applicable.

Special national conditions causing a deviation from this European Standard are listed in Annex ZB

(normative) which forms part of this standard.

National deviations from this European Standard are listed in Annex ZC (informative).

This European Standard has been prepared under a mandate given to CENELEC by the European

Commission and the European Free Trade Association and covers essential requirements of

EU Directive 2004/108/EC. See Annex ZZ.
NOTE In this standard the following print types are used:
– Requirements proper: in roman type.
– Test specifications: in italic type.
– Explanatory matter: in smaller roman type.

the following tests:

Moving parts, if any, are locked and a current is passed individually through each winding,

this current being such that the temperature of the relevant winding is equal to the

maximum temperature measured under the conditions specified in 14.1. This temperature

is increased by whichever value is chosen from the following table. The total time during

which the current is passed is as indicated in Table Z1 for the temperature increase

chosen.

Temperature increase Total time
ºC (K) h
0 ± 3 p
10 ± 3 0,5 p
0,25 p
20 ± 3
0,125 p
30 ± 3
In general, p equals 8 000 for controls for EN 60335-1 applications.

The total time is divided into four equal periods, each of them being followed by a period of

48 h during which the control is subjected to a humidity treatment as specified in 12.2. After

the final humidity treatment, the insulation shall withstand an electric strength test as

specified in Clause 13, the test voltage for the electric strength being, however, reduced to

50 % of the values specified in the table of that clause.

Failure of only one of the six samples during the first of the four periods of the test is

ignored.

SIST EN 60730-1:2012

If one of the six samples fails during the second, third or fourth period of the test, the

remaining five samples are subjected to an additional fifth period of passing current and

humidity treatment, followed by an electric strength and insulation resistance test as

specified before.
Failure of any of the remaining five controls will entail a rejection.

The controls are then subjected to the test of 17.8, but only for half the number of cycles

specified in that subclause. All controls shall then withstand an electric strength test as

specified before.

NOTE 1 Examples of cases where there may be doubt with regard to the classification of the insulating system

of a winding are those cases where well-known insulating materials are used in an unconventional way, where

combinations of materials of different temperature classes are used at a temperature higher than that allowed for

the lowest class used or where materials are used for which no sufficient experience is available, as may be the

case for integral core insulation.

NOTE 2 If it is desired to establish that the insulation system falls within the temperature class claimed by the

manufacturer, the winding temperature must be equal to the temperature limit for the class of insulation claimed,

increased by the temperature increase chosen from the table.

NOTE 3 The temperature increase chosen from the table should be agreed with the manufacturer.
