14、standards under the name Canadian Standards Association, and provides certification and testing under the name CSA International. CSA International provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of t
15、heir manufacture to indicate conformity with CSA Standards. CSA Certification for a number of products is provided in the interest of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for ac
16、ceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products for which certification is desired by producers, consumers, or other interests. In performing its functions in accordance with its objectives, CSA does no
17、t assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represent its professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standa
18、rd is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new feature may be deemed to meet the Standard providing the feature or difference is found acceptable utilizing appropriate CSA International Operating Procedures. Products that comply with
19、this Standard shall not be certified if they are found to have additional features which are inconsistent with the intent of this Standard. Products shall not be certifiable if they are discovered to contravene applicable laws or regulations. Testing techniques, test procedures, and instrumentation
20、frequently must be prescribed by CSA International in addition to the technical requirements contained in Standards of CSA. In addition to markings specified in the Standard, CSA International may require special cautions, markings, and instructions that are not specified by the Standard. Some tests
21、 required by CSA Standards may be inherently hazardous. The Association neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed, whether performed in whole or in part by the manufacturer or the Association, and wheth
22、er or not any equipment, facility, or personnel for or in connection with the test is furnished by the manufacturer or the Association. Manufacturers should note that, in the event of the failure of CSA International to resolve an issue arising from the interpretation of requirements, there is an ap
23、peal procedure: the complainant should submit the matter, in writing, to the Secretary of the Canadian Standards Association. If this Standard is to be used in obtaining CSA Certification please remember, when making application for certification, to request all current Amendments, Bulletins, Notice
24、s, and Technical Information Letters that may be applicable and for which there may be a nominal charge.

28、ed 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. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance w
29、ith conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all intere
30、sted National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote internat
31、ional unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in t
32、he latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subje
33、ct of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60335240 has been prepared by subcommittee 61E: Safety of electrical commercial catering equipment, of IEC technical committee 61: Safety of household and similar elec

41、is also within the scope of this standard. So far as is practicable, this standard deals with the common hazards presented by these types of appliances. NOTE 2 Attention is drawn to the fact that - for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements
42、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, the national water sup
43、ply authorities and similar authorities; - for appliances intended to be used outdoors, additional requirements may be necessary. This standard does not apply to - appliances designed exclusively for industrial purposes; - appliances intended to be used in locations where special conditions prevail,
44、 such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); - continuous process appliances for the mass production of food. 2 Definitions This clause of part 1 is applicable except as follows. 2.2.4 Addition: NOTE The rated power input is the sum of the power inputs of all t
45、he individual elements in the appliance which can be on at one time; where there are several such combinations possible, that giving the highest power input is used in determining the rated power input. -6- 60335-2-50 0 IEC:2000(E) 2.2.9 Replacement: normal operation: Operation of the appliance unde
