Regarding the classification of PED devices 2017-12-09
Thread Content
I have a question: according to the PED regulations, manufacturers are required to classify pressure equipment, with the types of such equipment including vessels, pipelines, safety accessories, pressure accessories, and assemblies. (b) in Article 4(1) of PED (2014/68/EU): Pressure equipment that is heated directly by fire or by other means and poses a risk of overheating, and is used to generate steam or superheated water at a temperature exceeding 110°C with a volume of more than 2 L, as well as all pressure cookers (Appendix II, Table 5). According to this provision, does it mean that only steam or hot water boilers heated by flame or other means can be evaluated in accordance with Table 5 of Appendix II? Can heat transfer oil boilers also be classified in this way? ? Also, where can I find a detailed definition of the components? Thank you very much
For the evaluation of assemblies, refer to clause 4.2. Principle: 1. All container types are evaluated separately to determine their hazard level. Get certification separately. 2. Piping systems are evaluated separately to determine their hazard level, and certification is obtained separately. 3. Pressure-bearing accessories, such as valves and other devices with pressure chambers, are evaluated separately to determine their hazard level, and they are certified individually. 4. Safety accessories such as safety valves, rupture discs, pressure switches, etc., are evaluated separately to determine their hazard level, and are certified individually. 5. Finally, conduct a comprehensive assessment by combining points 1, 2, and 3, using the highest risk level as the risk level for the entire device. Conduct a comprehensive certification assessment.
