Regulation (EC) No. 640/2009 - Scope
2. This Regulation shall not apply to:
(a) motors designed to operate wholly immersed in a liquid;
(b) motors completely integrated into a product (for example gear, pump, fan
or compressor) of which the energy performance cannot be tested
independently from the product;
(c) motors specifically designed to operate:
(i) at altitudes exceeding 1 000 metres above sea-level;
(ii) where ambient air temperatures exceed 40 °C;
(iii) in maximum operating temperature above 400 °C;
(iv) where ambient air temperatures are less than – 15 °C for any motor or less than 0 °C for a
motor with air cooling;
(v) where the water coolant temperature at the inlet to a product is less than 5 °C or exceeding
25 °C;
(vi) in potentially explosive atmospheres as defined in Directive 94/9/EC of the European
Parliament and of the Council ( 3 );
(d) brake motors;

Revised Regulation (EC) No. xxx/2012
2. This Regulation shall not apply to:
(a) motors designed to operate wholly immersed in a liquid;
(b) motors completely integrated into a product (gear, pump, fan or compressor)
that cannot be tested separately from the machine even with provision of
temporary end shield and drive end-bearing and for which the separation of
the motor from the rest of the product would render the motor inoperative
(c) motors specifically designed to operate exculsively:
(i) at altitudes exceeding 1 000 4000 metres above sea-level;
(ii) where ambient air temperatures exceed 60 40 °C;
(iii) in maximum operating temperature above 400 °C;
(iv) where ambient air temperatures are less than – 15 20 °C for any motor or less than 0 °C for a
motor with air water cooling;
