The difference of the dielectric strength test instrument on standards IEC60065 and UL1310

 
https://www.pegotester.com/dielectric_strength_test_instrument.html#_jcp=3_17

The dielectric strength test instrument is an auxiliary equipment for testing the dielectric strength of insulating material. The two standards IEC60065:2014 and UL1310:2017 have referred this equipment, but have difference on the details. In standard IEC60065:2014, there are detailed drawings as below, but there are no specific regulations on the material of the electrode, in the standard UL1310:2017, the size and material of the electrode are described in detail, but no drawings are given.


In IEC60065:2014:


In UL1310:2017: 


 But in practice, we usually make two standard requirements into one device, the equipment will includes 2 electrodes, the electrode has diameter 5mm±0.1mm and weight of 100g±1g is conform to IEC60065 standard, and the other electrode has diameter 6.4mm±0.1mm and weight of 50g±1g is conform to UL1310 standard. The electrodes are normally made of stainless steel. In UL1310, it mentions that the electrode also can made of brass, but compared with stainless steel, the brass will oxidize after long-term use and cause poor contact.

 

Below is the difference between the standards IEC60065 and UL1310, and also it is the parameters of dielectric strength test instrument made by PEGO, please contact the sales to get the formal quotation.

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5   1.  Introduction: The high current arc ignition tes t apparatus is designed according to  IEC60950-1:2001  clause 4.7.3.6 , BS/EN60950-1:2001, BS7002:2001, GB4943-2001 and UL746A, IEC60947.1:1999, GB/T14048.1-2000, IEC730.1:1993, GB14536.1-1998 and etc..  It ’ s used to measure and assess  solid insulating material against to resistance to ignition from arcing electrical sources. A power 240V(AC)/60Hz is to be supplied to the test electrodes  (fixed electrode and movable electrode) , a series (inductive-resistive) air core impedance is to be provided to yield a short circuit current of 32.5A and a power factor of 0. 5. The sample is be to positioned with the electrodes making initial contact on the surface of the sample, the circuit is to be energized and the cyclic arcing started. The timing of arcs is to be adjusted to a rate of 40 arcs/min, the rate of electrode separation is to be 254±...
