PED Pressure Vessel
Pressure Vessel Guidelines (Pressure Equipment Directive, 97/23 / EC)
Design Pressure vessels, heat exchangers, steam boilers, pipes, pressure parts, pressure devices, etc. where the maximum allowable pressure is greater than 0.5 bar, all parts, and products related to pressure, etc. included in pressure equipment will, however, be items that apply to the transfer pressure vessel and the simple pressure vessel directive are excluded, and products with relatively low pressurization are included in the machine instructions.
Product Classification and Conformity Assessment According to the Degree of Danger
Pressure vessels are classified into the following four according to the degree of danger, and manufacturers can choose Module among them. (2014/68 / EU ANNEX II, III)
| Category I | Module A |
|---|---|
| Category II | Module A2, D1,E1 |
| Category III | Module B+D, B+F, B+E, B+C2, H |
| Category IV | Module B+D, B+F, G, H1 |
The category is divided as follows by ANNEX II of 97/23 / EC Directive, and the applicable Table is determined according to the type of pressure vessel and type of fluid, state, maximum pressure, size, etc.

| Product | Vessels | Piping | Fluids |
|---|---|---|---|
| Gas, liquefied gas, pressurized dissolved gas, vapor and marine liquid with a vapor pressure above 0.5 bar above the image atmospheric pressure (1.013 mbar) at the maximum permissible temperature | Table 1 | Table 6 | Group 1 |
| Table 2 | Table 7 | Group 2 | |
| Liquids whose vapor pressure does not exceed 0.5 bar above normal atmospheric pressure (1.013 mbar) at the maximum permissible temperature | Table 3 | Table 8 | Group 1 |
| Table 4 | Table 9 | Group 2 | |
| There is a risk of overheating, steam or superheated water above 110 ° C as a pressure vessel for direct or indirect heating, produce a vessel with a volume of 2 liters or more to produce, and all pressure cooking equipment | Table 5 | ||
