1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This document specifies the safety requirements for household and similar use UV radiation water treatment appliances.
This document deals with the safety of UV radiation water treatment appliances for household and similar purposes, their rated voltage being not more than 250 V.
Appliances not intended for normal household use but that nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops and in light industry and farms, are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home.
However, in general, it does not take into account
——persons (including children) whose
