在研制安全火花型装置时,由于已制定了与放电持续时间和电路断开速度有关的较精确的引燃标准,因此用电路检测法来评价安全火花性能已成为比较可靠的方法。此法将逐渐被认为可比用传统的爆炸室试验法更客观,并在任何情况下均可行的安全火花评价法(因为爆炸室试验对转换状态实际上是不能控制的)。 In the development of safe sparking devices, the use of circuit testing to evaluate safe spark performance has become a more reliable method because of the more accurate ignition criteria associated with the duration of discharge and the rate of circuit breaking. This method will gradually be considered to be more objective than the traditional explosion chamber test and is practicable in any case by the safety spark evaluation method (since the explosion chamber test is virtually uncontrollable for the transition state).
