Nature of the Pressure Vessel Test

This section deals with the practical experience with pressure vessels of the American type in tests conducted in Professor Yoshida s Laboratory at the University of Tokyo, 

Gunpowder Research Laboratories of Nippon Oil Fats Co. 1H1 1) Pressure Vessels and Cups Used The apparatus used at Yoshida s Laborayory is shown below. 

The test apparatus is made of SUS type 316 stainless steel, and its lateral view and sectional view are given in Fig.3.74. An electric furnace with 8.4 Q nichrome wire in which a voltmeter and an ammeter were installed is used for heating. The sectional view of the electric furnace is presented in Fig. 3.75. The supply voltage is adjusted by a 2-kW voltage regulator. The sample cup is shown in Fig.3.76 (a). It is made of aluminium 

The test apparatus used at Nippon Oil and Fats Co. is as follows. 

Using orifice plates of 1 mm and 9 mm in diameter, perform the test 10 times for each sample, and record the number of burstings. The rest of the procedure is the same as for the conventional method.
