Reid Vapour Pressure

IP 69 & IS 1448 (P:39) 1967). Used to determine the vapour pressure of volatile non-viscous petroleum products except liquefied petroleum gases. The Vapour pressure bomb is made of brass heavily Chromium plated and consists of air chamber and gasoline chamber of definite dimension and volume ratio. A pressure gauge of required range is fitted above the air chamber. The joints are made leak proof by neoprene washers. The water bath used is of such dimensions that the vapour pressure bomb may be immersed to at least 1 inch above the air chamber and maintained at a constant temperature of 100 deg. C +/- 1 deg. C.
