Assemblies Intentions and enforcement

Intentions Free movement CE marking for vessels, accessories and assemblies Well-defined responsibilities Manufacturer, assembler and user Safety Pressure equipment and functional whole

Assembly definition Several pieces of pressure equipment Functional whole Assembled by a manufacturer

Assembly definition functional whole Art. 1 § 2.1.5, Art. 3 § 2.2 and Guideline 3/8 Pressurized system, connected, integrated, functional, form a whole, ready for placing on the market and putting into service Consequences clarification in principle, but some room for interpretation of the borderline of an assembly

Assembly definition assembled by a manufacturer Recital 5 PED, Guideline 3/1 and 3/2 PED relates only to assemblies which are fabricated by a manufacturer Consequences user is responsible for assembling, national regulations apply; delegation of responsibility to national inspection body may possible

Placing on the market The product is made available for the first time on the EC market Handover from manufacturer to user Consequences: Assemblies built on site by a manufacturer are also covered; Essential criterions: time of placing on the market, responsibility of the user

Time of placing on the market Extension of an existing assembly existing part is not replaced on the market Consequences: existing assembly + items of PE existing assembly + new assembly CAP apply only to the new equipment taking into account the input of the already existing assembly

Placing on the market PED and non PED assemblies PED assembly with non PED items e.g. compressor in a refrigeration system Non PED assembly with PED items e.g. mobile crane, tractor

Conformity assessment procedures on assemblies Art. 10 PED CAP limited to design and safety accessories Consequences only modules of the design phase apply;

Essential safety requirements ESR when corresponding hazards exist. Specific requirements 2.3, 2.8, 2.9 and 5 Annex I Consequences hazards shall be analysed

“Category” of assemblies Determined by the item of pressure equipment of the highest category, exempted safety accessories Applies for design and protection, not for the production phase

“Categories” of permanent joints No formal rule in the PED Effect of joining on the integrity and the items concerned shall determine the category. (Guideline 3/15)
