What is IEC60950?What is the standard IEC60950 test?
IEC60950: the national standard of the IT security test is the national standard of the People's Republic of China GB4943-- the safety of information technology equipment (including electrical equipment).
The basic concept
In IEC60950 and gb4943-2011, the minimum safe distance required for different voltage levels is specified, and the safety distance includes electric distance and creepage distance.There are two aspects to ensure the minimum safe distance for switching power supply:
1. The safe distance of one side circuit to the enclosure (protection ground);
2. The safe distance between the primary side circuit and the secondary circuit.
To get a higher precision of data acquisition ability, for test and measurement equipment design engineers, in the case of a high common-mode voltage affect system measurement of small signal change is a challenge.These high voltages are mainly generated by the potential difference between the two ground levels, or the transient overpressure caused by the surge of power surges caused by lightning or motor/switching equipment.These voltages not only affect the accuracy of the measurement, but also can damage the system itself and cause the user's electric shock hazard.
The following products can be safely tested:
Corresponding to the international standard IEC60950: microcomputer, portable computer, learning machine, computer games, CRT and LCD, projectors, printers, switching power supply, charger, power adapter and computer peripheral equipment, UPS power supply, etc.The equipment used in the transformer, printing plate and other components.
IEC test fee
First of all, the vibration test charge is based on the vibration table used. The charging of vibration table of different thrust is different.Secondly, the vibration table of the selected thrust is determined according to the united testing, the size and weight of the test pieces.
united testing relies on talents, technology, information, certification, detection of powerful resources and support, for many industries and products provide one-stop comprehensive quality solutions, improve enterprise competitive advantage, to meet the higher requirements for quality.Help enterprises to cross trade technical barriers, reduce trade risks, and provide product international market passes.For details, please send the product and relevant information to our company email: hofferlau@uni-lab.hk, support@uni-lab.hk or call service hotline: 0755-86180996 or add WeChat: 13699796815.
