SAFETY REQUIREMENTS
FOR RADIO TRANSMITTING EQUIPMENT
INTRODUCTION
This third edition of safety requirements for radio transmitting equipment supersedes, and replaces in a
215 (1978) and 284 (1968).
single volume, two earlier IEC Publications:
The requirements and test methods in this standard are similar to those given in the second edition of
I E C Publication 215 and continue to apply only to radio transmitting equipment operating under the
responsibility of skilled personnel as defined in Sub-clause 3.1. The text of Appendix E is based on the
284, which has now been withdrawn.
contents of I EC Publication
ational bodies referred to in this standard
The titles of I EC publications and publications of other inte rn
are given in Appendix A.
1. Scope
This standard applies to radio transmitting equipment, including any auxiliary apparatus neces-
sary for its normal operation as defined in I EC Publication 244-1, operating under the responsi-
bility of skilled personnel. It applies to all radio transmitting equipment and ancillary apparatus,
associated feeder
including combining units and matching networks. Only the antenna system and
lines are excluded.
This standard does not apply to transmitters of safety-insulated construction using double insu-
lation or reinforced insulation and without provision for protective earthing.
This type of equipment is designated "Class II Equipment" in I EC Publication 536 and is usually
marked with the symbol shown in Sub-clause C2.2 of Appendix C.
2. Object
This standard deals with protection against:
— electric shock;
— skin burns;
— high temperature and fire;

implosion and explosion;
— harmful radiation;

miscellaneous hazards.
Design and construction requirements and, where appropriate, test methods are specified
covering:
a) the safety of skilled personnel when operating, carrying out routine adjustments to, and as far as
practicable, during fault finding and repairing the equipment;
b) the safety of personnel, including unskilled personnel directed by skilled personnel, when the
equipment is operating normally, and also when operating under certain specific fault conditions
which may arise in normal use;
c)
the prevention of fire and its spread.
These requirements do not necessarily ensure the safety of unskilled personnel working on the
equipment when it is not in normal operation.

— 11 —
215©IEC1987
Tests are specified, where appropriate, for checking that the equipment meets the safety require-
ments of this standard when operating normally and also under the specified fault conditions. The
tests should be carried out on a representative set of equipment in order to determine whether the
design meets the requirements of this standard. The tests are neither mandatory nor limiting and
may be modified by agreement between manufacturer and purchaser.
The use of this standard is not, however, intended to be restricted to type tests. It may also be used
for acceptance tests after installation of the equipment, for tests after modifications to pa rts of the
equipment, and for tests at appropriate intervals to ensure the continuing safety of the equipment
throughout its life.
SECTION ONE — TERMINOLOGY

personnel.
Guidance on assessing the competence of personnel for designation as skilled is given in Appen-
dix D.
The above definition and the guidance in Appendix D detail the minimum requirements for a skilled person. In

some
certification.

b) the voltage exceeds 72 V peak, but the following limits with regard to both current and capacity
apply:

injury.
SECTION TWO — CONDITIONS OF NORMAL USE
AND FAULT CONDITIONS
4. Introduction
This section sets out the range of conditions of normal use and the fault conditions under which
the equipment may operate without danger to personnel, including unskilled personnel directed by

— 15 —
215©IEC1987
skilled personnel. The equipment shall meet the safety requirements of this standard when oper-
ating under the conditions of normal use given in Clause 5 and also when any of the initial fault
conditions detailed in Clause 6 have been applied.
5. Conditions of normal use
The ambient atmospheric conditions for the equipment are within the following range:
a)
— temperature: +5 °C to +45 °C;
relative humidity: 45% to 75%;
— air pressure: 86 kPa to 106 kPa (kN/m2),
(860 mbar to 1 060 mbar);
or within more stringent conditions agreed between manufacturer and purchaser.
b)
The supply voltage and frequency are within the range for which the equipment has been
designed.
c) For a.c. equipment, the waveform of the supply voltage is substantially sinusoidal. (See Clause 5
of I EC Publication 244-1 for the definition of "substantially sinusoidal").
d) For equipment which may be operated from a.c. or d.c., either supply is applied separately.
e) The safety earth terminals or contacts, if any, are connected to earth (see Sub-clause 12.1). Any
other earth terminals shall also be connected to earth, unless the terminals are designed to be
tightened by hand; in which case, they are left unconnected.
f) The access doors and cover plates or other protective covers, if any, are closed or fixed in
position, unless they are designed to be opened or removed by hand; in which case they are left
open or removed.
g) The equipment is operating in any position for which it has been designed to be used.
h) The equipment has its accessible controls at any setting.
The equipment is operating with any input signal condition given in the equipment specifica-
i)
tion.
6. Fault conditions
Operating under fault conditions denotes that, with the equipment operating under the condi-
tions of normal use given in Clause 5, one of the faults a) to h) listed below, is present together with
any associated consequential faults arising. The initial faults shall be applied separately, in tu rn, in
any convenient order.
circuits across creepage distances, if they are less than the values given in Appendix B,
a) Short
unless the insulation complies with the provision of Clause 16.
Sho circuits across clearances in air, if they are less than the values given in Appendix B.
b) rt
c) A potentially dangerous failure of any component as determined from inspecting the equipment
and studying the circuit diagram, unless the component is known to comply with an I EC test
recommendation appropriate to the conditions of use in the equipment.
d) Connection of any unfavourable impedance to the radio-frequency output connection, including
open circuits and short circuits.

215©IEC1987 — 17 —
e) Failure of any cooling system.
f)
Continuous operation of motors, intended for intermittent operation, unless protection against
this is included in the equipment.
g) Locking of moving parts in rotating or linear operating devices, if these pa rts can be jammed by
mechanical failure.
h) The loss of a phase on a three-phase supply.
SECTION THREE — COMPONENTS AND CONSTRUCTION
oduction
7. Intr
The purpose of this section is to ensure that the equipment is designed and constructed to ensure
safety of personnel throughout the life of the equipment.
Where no test method is given, compliance shall be checked by visual inspection and where
appropriate by a functional test.
Components
8.
8.1 General requirements
Components shall not be loaded in excess of their ratings under normal conditions nor, as far as
practicable, under fault conditions. Normal and fault conditions are detailed in Clauses 5 and 6.
Components which are known to comply with an I EC test recommendation appropriate to the
conditions of use in the equipment need not be tested.
When this is not so, the components may be tested either in the equipment or externally under
conditions equivalent to those applying in the transmitter. The number of compo
