Abstract | To provide a gas leakage inspection method and a gas leakage inspection device capable of discriminating whether the leakage of fuel gas is caused by permeation of a seal material or by a gap occurring between a seal material and another member.SOLUTION: Disclosed is a gas leak inspection method which includes a determination step of determining a leak state where a gap exists between an object to be inspected and a seal material when the amount of gas to the outside per unit time after lapse of a predetermined time from the introduction of gas to be inspected is larger than a predetermined value and also determining a permeation state where the gas to be inspected is permeated from the seal material when it is equal to or smaller than the predetermined value.SELECTED DRAWING: Figure 5
【課題】燃料ガスの漏れが、シール材の透過によるものか、シール材と他の部材との間に生じている隙間によるものかの切り分けが可能なガス漏れ検査方法及びガス漏れ検査装置を提供すること。【解決手段】検査対象ガスを導入してから所定時間経過後の単位時間当たりの外側へのガス量が、所定値よりも大きいときに、被検査対象部材とシール材との間に隙間があるリーク状態と判定し、所定値以下のときに、シール材から検査対象ガスが透過している透過状態と判定する判定工程を有するガス漏れ検査方法である。【選択図】図5 |
