introduction
This portion is recognized for household electrical appliances and similar requirements according to the manufacturer instructions and used under normal conditions, is of
With an acceptable level of risk international protection of electrical, mechanical, thermal, radiation and fire, it also includes the possible use of expected
Abnormal circumstances, and taking into account electromagnetic interference affects the way for the safe operation of the appliance.
In developing this part has been as much as possible into account the requirements of IEC 60364 in order to make electrical appliances when connecting to the grid
Gas wiring rules requires coordinated. But electrical wiring rules may be different for each country.
If a number of functions related to the special requirements of the appliance IEC 60335 series of different parts, as far as is reasonable in the circumstances
Under the special requirements of the relevant standards should be applied to each function separately. If applicable, taking into account the impact of this function to other functions.
Note 1: refers to the technical committee responsible for determining the criteria to determine the appliance in Part 2, other than appliances involving general requirements, no special requirements of the problem.
When the special requirements not included in Part 1 of the appended claims when hazardous, Part 1 applies.
Note 2: refers to when the IEC 60335 series of standards has been considered dangerous instrument development process encountered dangerous situations involving other than the standard does not apply, for example,
The surface temperature of many appliances, for example, ISO 13732-1 claim hot surface, do not apply to the first or the second part of the standard.
If the test has found damage to other standard safety features principle, it is considered that the appliance does not meet the requirements of this section.
Material or appliance use a structure other than the requirements of this, the product may be intended in this section to these requirements
Inspection and testing. If found to be substantially equivalent, it can be determined which comply with this part.
For the electrolytic cell, according to the present selection test section, and does not require the machine to be tested as a prerequisite. For example reference
IEC 60335 Part 2 of Chapter 24, however, comply with this part if the cell is mounted on the appliance, the appliance of the relevant test
Test may be suitably reduced if there is, comprising a control system or the protection system shall comply with this part.
In particular, the structure can be carefully examined and tested separately in different cell, and therefore, when the electrolytic cell used in different appliances
When, inspection and tests required may be correspondingly omitted.
