changes become applicable will be stated in the relevant amendment or revision of Part 1.
This part 2 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into the
European Standard: Safety requirements for electric blankets, pads and similar flexible heating
appliances.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is

- additional annexes are lettered AA, BB, etc.;
- subclauses, notes and annexes that are additional to those in the IEC standard are prefixed with the letter Z.
NOTE 2 The following print types are used:
- requirements: in roman type;
- test specifications: in italic type;
- notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated noun
are also in bold.
There are no special national conditions causing a deviation from this European Standard, other than
those listed in Annex ZA to EN 60335-1.
There are no national deviations from this European Standard, other than those listed in Annex ZB to

Introduction
p Add:
An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this
standard are fully covered by the Low Voltage Directive, 73/23/EEC. For products having mechanical
moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/EC, has shown that
the risks are mainly of electrical origin and consequently this directive is not applicable. However, the
relevant essential safety requirements of the Machinery Directive are covered by this standard together
with the principal objectives of the Low Voltage Directive.
