For products covered by special requirements, their safety requirements are the general requirements combined with the special requirements.

The requirements include supplements and modifications to the corresponding clauses in the general requirements to provide complete requirements for each product.

In the case of the general requirements, they can be applied to various appliances not covered by the special requirements of the GB/T 4706 series of standards, as well as those according to the new principles.

In this case, consideration should be given to the classification of the appliance according to clause 6 and whether the appliance is attended or unattended.
