- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
- for appliances intended to be used in tropical countries, special requirements may be necessary;
- in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities. 2 This standard does not apply to
- pumps for circulating liquids other than water;
- pumps other than circulation pumps (IEC 335-2-41);
- circulation pumps intended exclusively for industrial purposes;
