1. Assemblies Intentions and enforcement

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

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

4. 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

5. 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

6. 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

7. 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

8. 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

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

10. 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

11. “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

12. “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)

13. Assembly Pressure vessel -accessories– piping

14. Assembly Pressure vessel -accessories– piping
Pressure vessel 16 bar, L
Pipe DN 32 mm
1. Pressure regulator 16 to 3 bar
Piping DN 32 mm
2. Pressure regulator 3 to 1,5 bar
Piping DN 50 mm

15. Assembly Pressure vessel -accessories– piping
How many assemblies?
Categories of the assemblies?
Categories of the permanent joints?
Conformity assessment procedures for the assemblies?
Involvement of notified bodies?

16. Assembly Pressure vessel -accessories– piping

17. Assembly Pressure vessel -accessories– piping
Pressure vessel 16 bar, L
Pipe DN 1/2”
1. Pressure regulator 16 to 50 mbar
Piping DN 1”

18. Assembly Pressure vessel -accessories– piping
How many assemblies?
Categories of the assemblies?
Categories of the permanent joints?
Conformity assessment procedures for the assemblies?
Involvement of notified bodies?
