在大多数的国标中,以及在欧州电工技术标准化委员会制定的欧州标准中,对一个回路,特别是对一个电源的安全火花性能的检验,一般来说分两步进行:——首先,在考虑了一定的安全系数的前题下,把电源的电参量与引燃曲线的电参量进行比较。这些引燃曲线是国际电工技术 In most national standards, as well as in the European standards developed by the European Committee of Electrotechnical Standardization, the verification of the safety spark performance of a circuit, in particular of a power supply, generally takes two steps: First, Under a certain safety factor, the electrical parameters of the power supply are compared with the electrical parameters of the ignition curve. These ignition curves are international electrotechnical
