A-deviations
A-deviation: National deviation due to regulations, the alteration of which is for the time being outside the
competence of the CENELEC national member.
This European Standard does not fall under any Directive of the EC.
In the relevant CENELEC countries these A-deviations are valid instead of the provisions of the European
Standard until they have been removed.
Clause Deviation

(DM 1 December 1980 and DM 10 September 1981 published in Gazzetta Ufficiale no. 285
dated 16.10.1981)
For insulation-enclosed switchgear and controlgear containing gas-filled compartments, the
design pressure is limited to a maximum of 0,5 bar (gauge) and the volume is limited to a
maximum of 2 m . Gas filled compartments having a design pressure exceeding 0,5 bar
(gauge) or a volume exceeding 2 m shall be designed according to the Italian pressure
vessel code for electrical switchgear.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
