Application

Pressure equipment according to these rules are components subject to gaseous or liquid fluids with a pressure above 0.5 bar. Pressure equipment may consist of more than one pressurized compartment.

The term pressure equipment in this section applies to the following components:

- pressure vessels, including mountings, necessary for performing the main functions listed in Pt.1 Ch.1 Sec.1 [1.2]

- other pressure vessels containing:

- toxic fluids

- fluids with flash point below 100°C

- fluids with temperature above 220°C

- fluids with pressure above 40 bar

- compressed gases where pd × V ≥1500 bar ltr

- boilers and hot water generators, including mountings

- thermal-oil heaters

- oil burners and oil firing equipment.

pd = design pressure

V = Volume

Pressure equipment according to [1.1.2] are subject to certification by the Society.

The control and monitoring systems shall be certified according to Ch.9 for the following:

- electrically heated pressure vessels

- boilers

- thermal-oil heaters

- hot and warm water generators
