introduction
In drafting this section has been assumed by appropriately qualified and experienced people to implement the provisions of this section.
This section is recognized Household and similar electrical appliances under normal use in the manufacturer's instructions noted that the conditions of the appliance
An internationally acceptable level of electrical, mechanical, thermal, fire and radiation hazard protection, it also includes the use of expected possible
Irregular situation, and to consider electromagnetic interference for the safe operation of the appliance impact way.
In developing this section has been taken into account as far as possible the requirements specified in IEC 60364, so that when the appliance is electrically connected to the grid
Gas wiring rules requires coordinated.
If a number of functions related to the GB 4706 appliance different specific requirements, as far as is reasonable in the circumstances, the relevant section
Particular requirements for points to be applied separately to each function. If applicable, taking into account the influence of one function to another function.
When other parts do not contain additional requirements involving dangerous for Part 1, Part 1 applies.
Note 1. In this section, when referring to "other parts", it refers to the specific requirements related to 4706 GB of.
This part is related to a security appliance product family standard, and in standards covering the same subject in the same level and category of
Priority.
Note 2. The standard deals with the same dangerous levels and categories do not apply, because it is already in the determination of GB 4706 series of standards and special requirements General Requirements
Considered within the scope. For example, many appliance surface temperature requirements, in addition to the first part and other parts of the common standards (such as for hot surfaces
The ISO 13732-1) Not applicable.
An appliance that complies in this part of the text, when examined and tested, found to have other features would prejudice the requirements of this relates
Security level, it will not be sentenced to comply with this section of the safety guidelines.
When using a material or product forms of construction of the section in the requirements, then the product can be in this section in accordance with these
Seeking intentions be inspected and tested. If found to be substantially equivalent, it may be considered to comply with the requirements of this section.
