A Comparison of the New and Old Standards for the Glow Wire Apparatus

The IEC60695-2-10 standard is a common test method for testing the flame retardant performance of materials used in electrical products. During use, the product may reach excessive temperatures due to overload, short circuit, electrical contact or other fault conditions that can cause a fire hazard. The glow wire test is to simulate the overloaded resistance heat source to apply thermal stress to the sample in a short time, and to evaluate the fire risk of the sample through observation and measurement. The glow wire test is suitable for resarching, production and quality inspection departments of electrical and electronic products, such as lighting equipment, low-voltage electrical appliances and household appliances, machine tool appliances, motors, electric tools, electronic instruments, electrical instruments, information technology equipment, electrical equipment and their components, and also applicable to insulating materials, engineering plastics or other solid combustible materials industry. There is difference on glow-wire apparatus in version 2013 and version 2000 of standard IEC60695-2-10, the details as below:
The purpose of the revision of the IEC 60695-2-10 standard is to reduce the influence factors of the test environment and equipment on the test results. The change in the diameter of the thermocouple greatly reduces the damage rate of the glow wire. The glow wire tester (models GW-1 and GW-1H) produced by PEGO can completely meet the requirements of the latest standard.

How to conduct the ESD test?

  What is ESD test? Electrostatic discharge immunity test is a basic EMC test . S tandard IEC61000-4-2 provide the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and to adjacent objects . T he standard establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. Electrostatic discharge is a transfer of electric charge between bodies of different electrostatic potential in proximity or through direct contact. The standard IEC61000-4-2 does not intend to specify the tests to be applied to particular apparatus or system, it is to give a general basic reference to all concerned product .   S o before conduct the test, an appropriate test level should be selected according to the product's characters and its working occasion.   Contact discharge and air discharge methods The test leve...

The relationship between standards IEC62262 and IEC60068-2-75

  The IK code is a coding system to indicate the degree of protection provided by an enclosure against harmful external mechanical impacts. The standard IEC62262 defines the impact energy corresponding to different IK codes. In general, the degree of protection applies to the complete enclosure. If parts of the enclosure have differing degrees of protection, the latter shall be indicated separately. IK00 IK01 IK02 IK03 IK04 IK05 IK06 IK07 IK08 IK09 IK10 IK11 0 0.14J 0.2J 0.35J 0.5J 0.7J 1J 2J 5J 10J 20J 50J IK00 - no protection IK01 - withstands 0.14J impact force (equivalent to the impact of an object weighing 0.25KG falling from a height of 56mm on the surface) IK02 - Withstand 0.2J impact force (equivalent to the impact of an object weighing 0.25KG falling from a height of 80mm on the surface) IK03 - Withstand 0.35J impact force (equivalent to the impact of an object weighing 0.2KG falling from a height of 140mm on the surface) IK04 - Withstand 0.5J impact force (equivalent to t...
