Discuss and Practice of Calibration on Fully-sealed Sample Piece in Leak Detection
Zhu Zeng-de · Automobile Technology & Material · 2001
Fully - sealed sample piece is one of important parts of leak detection equipment and its leakproofness directly affects accuracy of measurement. In this paper the necessity of calibration on the sample piece is demonstrated. Based on the characteristic that most systems have a cistern, a calibrating method is proposed, by which the leakproofness of sample piece can be detected and quantitative estimate can be given.
