This Standard deals with the safety of toys that have at least one function dependent on electricity. Additional requirements for experimental toys are given in Annex A. Toys using electricity for secondary functions are within the scope of this Standard. In order to comply with this Standard, electric toys must also comply with Annex A in GB 6675-2003, because it covers the hazard which is different from the hazard caused by the use of electricity. .
GBT 14048.10-2008 applies to inductive and capacitive proximity switches that sense the presence of metallic and/or non-metallic objects; ultrasonic proximity switches that sense the presence of sound reflecting objects; photoelectric proximity switches that sense the presence of objects; and non-mechanical magnetic proximity switches that sense the presence of objects with a magnetic field. These proximity switches are self-contained; have semiconductor switching elements(s); and are intended to be connected to circuits. The rated voltage of proximity switch shall not exceed 250V (50Hz/60Hz) a.c. or 300V d.c. This Part is not intended to cover proximity switches with analogue outputs.
This Standard applies to electronic apparatus designed to be powered from grid power supply, from power supply equipment, from battery or from remote power system and intended for reception, generation, recording or reproduction of audio, video and relevant signals. It also applies to apparatus designed to be used exclusively in combination with the above-mentioned apparatus. This Standard primarily applies to the apparatus intended for household and similar general use but which may also be used in places of public locations such as schools, theatres, places of worship and the workplace. PROFESSIONAL APPARATUS intended for use as described above is also covered unless it is specifically within the scope of other standards. This Standard only applies to safety aspects of the above apparatus; it does not apply to other matters, such as style or performance. If above apparatus is designed to be connected to TELECOMMUNICATION NETWORK or similar network, for example by means of an integrated modem, this Standard also applies.
