One, suitable scope:
The sound equipment of the family expenses that applies to the power supply of power source of electrified wire netting that applies for an entrance and similar and general use is safe of quality clearance book send appearance to examine reach right permissive already use " safe mark " the sampling inspection of the product.
Sound equipment is to point to GB8898 (IEC65) inside standard suitable scope, the makes by independent unit equipment of family expenses and general use and the whole set of equipment that a certain number of independent and unit combination make. Basically recording of tuner of radio, broadcast, tape recorder, tape gets stuck, phonograph of turntable, CD, card pulls OK sound box of machine, equalizer, amplifier, active, LD and V-CD CD machine.
2, examine basis and examine project
1. uses a level:
The electron of the family expenses of power supply of power source of GB8898- electrified wire netting and similar and general use and the safety of concerned equipment ask
2. Examine project:
Mark
The temperature rise below regular job requirement
The temperature rise below high temperature environment
The danger getting an electric shock below regular job requirement
Insulation requirement
Breakdown condition
Mechanical intensity
Receive the component of power source of electrified wire netting repeatedly
