FOREWORD
This amendment has been prepared by IEC technical committee 72: Automatic controls for
household use.
The text of this amendment is based on the following documents:
FDIS Report on voting
72/577/FDIS 72/580/RVD
Full information on the voting for the approval of this amendment can be found in the report
on voting indicated in the above table.
This International Standard integrates the contents of IEC 60730-2-1:1989, Automatic
electrical controls for household and similar use – Part 2: Particular requirements for electrical
controls for electrical household appliances, and as a result cancels and replaces it.
This amendment is based on 60730-1, edition 3 (1999).
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until 2005. At this date, the publication will be

11.13.1 Protective controls
Protective controls shall
– be so designed and constructed as to be reliable and suitable for their intended duty and
take into account the maintenance and testing requirements of the devices, where
applicable,
– be independent of other functions, unless their safety function cannot be affected by such
other functions,
– comply with appropriate design principles in order to obtain suitable and reliable
protection.
These principles include, in particular, fail-safe modes, redundancy, diversity, and self-
diagnosis.
Operating controls shall not be used as protective controls.
Compliance is checked by carrying out the relevant tests specified in this standard and the
appropriate part 2.
NOTE A test method is under consideration.
11.13.2 Pressure limiting devices
These devices shall be so designed that the pressure will not permanently exceed the
maximum allowable pressure of the controlled application; however, a short duration pressure
surge of no more than 10 % of the pressure surge is allowable, where appropriate, or where
not specified in the relevant standard for the controlled application.
11.13.3 Temperature monitoring devices
These devices shall have an adequate response time on safety grounds, consistent with
measurement function.

Micro-interruption - - - - - -
1)
Applies to controls galvanically connected to mains.
2)
No requirement up to 24 V a.c. r.m.s. if the circuit is insulated from the mains by double or reinforced
insulation (may be earthed).
3)
There are no electric strength requirements for micro-interruption, since the satisfactory completion of the
tests of Clauses 15 to 17 inclusive are considered to be sufficient. Furthermore, for a control which has no
micro-disconnection in one position of its actuating means and micro-interruption in other positions, there are
no requirements for electric strength for those positions corresponding to micro-interruption.
4)
See 13.3.1.
5)
For the test of full-disconnection and micro-disconnection, contacts are opened automatically or manually and
tested as soon after opening as possible to ensure that the contact separation and the supporting insulation
are satisfactory.
In the case of temperature-sensing controls, it may be necessary to provide special samples specially
calibrated to open between 15 °C and 25 °C to enable this test to be carried out at room temperature
immediately after removal from the humidity cabinet.
6)
Special components which might render the test impractical, such as electronic parts, neon lamps, coils or
windings shall be disconnected at one pole or bridged as appropriate to the insulation being tested.
Capacitors shall be bridged except for the tests for operational insulation when one pole is disconnected.
Where such a proceeding is not practical, the tests of Clauses 15 to 17 inclusive are considered to be
sufficient.
7)
Any metal in contact with accessible metal is also regarded as accessible.
8)
For the tests of supplementary and reinforced insulation, the metal foil is applied in such a way that sealing
compound, if any, is effectively tested to accessible insulating surfaces.
9)
For controls incorporating reinforced insulation as well as double insulation, care should be taken that the
voltage applied to the reinforced insulation does not over-stress the basic or the supplementary parts of the
double insulation.
10)
For class I and class 0I controls and controls for class I situations, care must be taken that adequate
clearance is maintained between metal foil and accessible metal to avoid over-stressing of insulation between
live parts and earthed metal parts.
11)
The high-voltage transformer used for the test must be so designed that when the output terminals are
short-circuited after the output voltage has been adjusted to the test voltage, the output current is at least
200 mA. The overcurrent relay must not trip when the output current is less than 100 mA. Care shall be taken
that the r.m.s. value of the test voltage is measured within ±3 %. See also Annex H.

In Canada and the USA, other values are applicable.

For incorporated and integrated controls, no temperature limit is applicable, but attention is drawn to the fact
that most equipment standards limit the temperature of terminals of fixed appliances to 85 °C, which is the
maximum allowable temperature for ordinary PVC cable insulation. The maximum temperature recorded should
not exceed the value declared in Table 7.2, item 21.
When a control is incorporated/integrated into an appliance, the terminals for external conductors will, as part
