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.

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.

1)
For operational insulation, the rated impulse voltage is derived from the value in column 3 of Table 20.1 which
covers the measured voltage across the clearance, unless otherwise declared and justified by the
manufacturer. If the secondary winding of the stepdown transformer is earthed, or if there is an earthed screen
between the primary and secondary windings, the reference for the rated impulse voltage for the clearances of
basic insulation on the secondary side shall be one step lower than that which covers the rated input voltage
of the primary side of the transformer.
The use of an isolating transformer without an earthed protective screen does not allow a reduction in the
rated impulse voltage.
2)
An explanation of pollution degree is given in Annex N.
3)
For altitudes of more than 2 000 m above sea-level, the values for clearances shall be multiplied with the
correction factor specified in IEC 60664-1, Table A.2.
NOTE For small values of clearances, the uniformity of the electric field can deteriorate in the presence of
pollution, making it necessary to increase the clearance values above the values of case B.

Add, after 20.1.12, the new subclause 20.1.13 as follows:
20.1.13 If the secondary of a transformer is earthed, or if there is an earthed screen between
the primary and secondary windings, the clearances of basic insulation on the secondary side
shall not be less than those specified in Table 20.2 but using the next lower step for rated
impulse voltage as a reference.
NOTE The use of an isolating transformer without an earthed protective screen or earthed secondary does not
allow a reduction in the rated impulse voltage.
For circuits supplied with a voltage lower than rated voltage, for example, on the secondary
side of a transformer, clearances of functional insulation are based on the working voltage,
which is used as the rated voltage for Table 20.1.

working voltages up to and including 300 V, between metal parts shall not be less than
0,7 mm.
This does not imply that the distance has to be through insulation only. The insulation may consist of solid material
plus one or more air layers.
For controls having parts with double insulation where there is no metal between basic
insulation and supplementary insulation, the measurements are made as though there is a
metal foil between the two layers of insulation.
20.3.2.1 The requirement of 20.3.2 does not apply if the insulation is applied in thin sheet
form, other than mica or similar scaly material.
– For supplementary insulation, it consists of at least two layers, provided that each of the
layers withstands the electric strength test of 13.2 for supplementary insulation.
– For reinforced insulation, it consists of at least three layers, provided that any two layers
together withstand the electric strength test of 13.2 for reinforced insulation.

60730-1 Amend 1  IEC:2003 – 35 –
Compliance is checked by inspection and by test.
20.3.2.2 The requirement of 20.3.2 does not apply if the supplementary insulation or the
reinforced insulation is inaccessible and meets one of the following criteria.
– The maximum temperature determined during the tests of Clauses 27 and H.27 does not
exceed the permissible value specified in Table 14.1.
– The insulation, after having been conditioned for 168 h in an oven maintained at a
temperature equal to 25 K in excess of the maximum temperature determined during the
tests of Clause 14, withstands the electric strength test of 13.2, this test being made on
the insulation both at the temperature occurring in the oven and after cooling to
approximately room temperature.
For optocouplers, the conditioning procedure is carried out at a temperature of 25 K in excess
of the maximum temperature measured on the optocoupler during the tests of Clauses 14, 27
and H.27, the optocoupler being operated under the most unfavourable conditions which
occur during these tests.
Compliance is checked by inspection and by test.
