Zusammenfassung:The BuAer M-117 pocket type demand mask leak tester was improved by the addition of an open circuit breathing vent. The design and advantages of this modification applied to pocket type testers is described. Necessary physical tests were made to develop data for calibration of bellows extension time in terms of per cent mask nitrogen and air leak volume. (Author)
