Dutch pressure vessel test: UN Series E, Test E.2<\/h1>\n

For the test, the test substance is heated in a pressure vessel, which is closed using aperture discs with orifices of various diameters. The pressure vessel also has a bursting disc, rated to burst at 620 \u00b1 60 kPa. This method is used to determine whether the substance can decompose itself under intense heat.<\/p>\n

The apparatus consists of a pressure vessel with orifice plate and bursting disc, which is inserted into a heating and protection device (Figure 1).<\/p>\n\n\n\n\n\n\n\n
