(If it permits the arrangement, it is to be adjusted to the higher limit value). 5.2.6. The points 5.2.4 and

14、5.2.5 are repeated 12 times. This results a total testing time of 288 h. 5.2.7. The point 5.2.3 is repeated per workday (6h after cold storage), while the test sample remains in the air - conditioning chamber. 5.3. The measured voltage may never come to less than 10 KV.EDS-T-5216SUPPRESSOR PLUG, IGN
