National standards
The motors comply with the IEC or European standards listed
above. The European standards replace the national standards
in the following European countries:
Germany (VDE), France (NF C), Belgium (NBNC), Great Britain
(BS), Italy (CEI), Netherlands (NEN), Sweden (SS), Switzerland
(SEV) etc.
The motors also comply with various national standards. The following
standards (with the exception of non-standard motors)
have been harmonized with IEC publication 60034-1 or replaced
with DIN EN 60034-1 so that the motors can be operated at standard
rated output.

Explosion-proof motors:
Since these comply with the European standards EN 50014,
EN 50018, EN 50019 and Directive 94/9/EG (ATEX 95), test certificates
issued by authorized testing agencies (PTB, DMT, etc.)
are accepted by all member states of the EU. The remaining
members of CENELEC, Switzerland in particular, also accept the
certificates.
Tolerances for electrical data
According to DIN EN 60034, the following tolerances are permitted:
Motors which comply with DIN EN 60034-1 must have a
voltage tolerance of –5% / frequency tolerance of –2% (Design A),
if utilized, the permitted limit temperature of the temperature
class may be exceeded by 10 K.
A tolerance of –5% also applies to the rated voltage range in
accordance with DIN EN 60034-1.
