Hot Arc Ignition (HAI) | |
HAI (high current arc ignition): the performance of high current arc ignition (HAI) is expressed as the number of arc rupture exposures (standardized for the type of electrode and the shape and electrical circuit) that They are needed to ignite a material when applied at a standard speed on the surface of the material. The number of arc rupture exposures required to ignite a material when applied at a standard rate on the surface of the material. Test procedure: A system for the high energy arc has been developed. The repeatability is shown by comparing the results in two different time frames. The results of the ignition tests are also presented for different types of materials. Statistical data that show the consistency of the test are also presented. Performance is expressed as the number of arc rupture exposures that are required to ignite a material when applied at a standard rate on the surface of the material. Ignition categories PLC 0 to 5 (performance level categories) According to UL 746 A, Section 3117 | |
Performance (PLC) | |
To avoid an excessive level of implicit precision and bias, the performance of the material for various tests are recorded as performance level (PLC) categories based on the test of the average results (instead of recording the exact numerical results) |
