38、s and intended for commercial use Annex ZZ (normative) Coverage of Essential Requirements of EU Directives .29hiINTRODUCTION It has been assumed in the drafting of this International Standard that the execution of its provisions is entrusted to appropriately qualified and experienced persons. This s

39、tandard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking into account the manufacturers instructions. It also covers abnormal situations that can be expected in

40、practice and takes into account the way in which electromagnetic phenomena can affect the safe operation of appliances. This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatibility with the wiring rules when the appliance is connected to the supply

41、 mains. However, national wiring rules may differ. If an appliance within the scope of this standard also incorporates functions that are covered by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as far as is reasonable. If applicable, the influence of one f

42、unction on the other is taken into account. An appliance that complies with the text of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by th

43、ese requirements. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with

44、the standard. When a part 2 standard does not include additional requirements to cover hazards dealt within Part 1, Part 1 applies. NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is not necessary to specify particular requirements for the

45、 appliance in question over and above the general requirements. This standard is a product family standard dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and generic standards covering a hazard are not app

46、licable since they have been taken into consideration when developing the general and particular requirements for the IEC 60335 series of standards. For example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as ISO 13732-1 for hot surfaces, are not

47、applicable in addition to Part 1 or part 2 standards.

48、 Part 1 is replaced by the following: appliances for keeping food and crockery warm not intended for household use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances. NOTE 101 These appliances are used, f

49、or example in restaurants, canteens, hospitals and similar commercial enterprises. The electrical part of appliances making use of other forms of energy is also within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by these types of appliances. NOTE 102 Attention is drawn to the fact that for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary; in many countrie
