IEC TS 60079-39:201 © IEC 201 – 43 – With these test setups an ignition probability of -3 or lower has been achieved, i.e in average one ignition in 000 contacts is allowed P r o c ed u r e t o d et er m i n e t h e i g n i t i o n l i m i t i n g v al u es : The determination of the ignition probability for Power-i was performed in compliance with the evaluation of the ignition tables and curves in IEC 60079-1 Annex A These values are based on the above mentioned ignition probability of -3 or lower Due to the characteristic of the Power-i system it is necessary to ensure that the system is in specified Power-i mode during the make/break contact of the STA The detector is used to monitor the system state Therefore the digital counter only counts valid contacts during Power-i mode The tests shall be performed with the STA in two different positions – as shown in and Figure B.7 The test results are to be found in Figure B.8, Figure B.9 and Figure B.1 The marked values in the measured curves are based on at least ignitions All tests had been performed with equipment group IIC for safety factor ,5 – by using an Oxygen enriched mixture, i.e 30 % hydrogen, 53 % Air and % oxygen (in accordance with IEC 60079-1 ) The resulting ignition values in Table are based on the following assumption: Figure B.1 shows the dependence of the minimum ignition energy in relation to the used hydrogen – air ratio of the gas mixture The minimum ignition energy is approximately µ J at 21 % hydrogen in air The used oxygen enriched mixture for safety factor SF ,5 for Group IIC has a minimum ignition energy of approximately µ J The safety factor SF ,0 for IIC and the safety factor SF ,5 mixtures for equipment group IIB and IIA are based on hydrogen air mixtures in accordance with IEC
