111 TESTING A NETWORK Final Commissioning I I Transair ® Advice for Final Commissioning of a Compressed Air Network I I Legal Requirement for Installers according to PED 2014/68/EU - ANNEX I Essential Safety Requirements Example - considering a system working at 6 bar pressure 1. Run compressor at 3bar pressure to check integrity of the Transair ® system and that the compressors are running correctly. 2. Leave the pipework under pressure for a period of 12 hours overnight. During this period the Transair ® system should be isolated from machines and tools (drop valves should be closed). 3. Upon checking of the system after the 12 hour period, the compressor read can show a 0.3 bar pressure loss (from 3 bar to 2.7bar with constant temperature). 4. The system pressure is increased to design pressure (6 bar in this example) for a further 4 hours again (with no leak recorded from the Transair ® system). 5. The system is then increased to 9 bar (1.43 x the max operating pressure) for a period of 1 hour with no further issues (NB: for this test, pressure of the system can exceed the maximum working pressure). 6. Purge the system, and you can start to work. 3.2. Final Assessment: Pressure equipment must be subject to final assessment as described below. 3.2.1. Final Inspection: Pressure equipment must undergo a final inspection to assess visually and by examination of the accompanying documents compliance with the requirements of the Directive. Test carried out during manufacture may be taken into account. 3.2.2. Proof Test: Final assessment of pressure equipment must include a test for the pressure containment aspect, which will normally take the form of a hydrostatic pressure test at a pressure at least equal, where appropriate, at the maximum allowable pressure multiplied by the coefficient 1.43. For category I series-produced pressure equipment, this test may be performed on a statistical basis. For series-produced pressure equipment under the article 4.3, this test is not necessary. . I I Requested Documentation for Category I Equipment To comply with the PED here is a list of documents you should provide to the end user and how to get them for Transair ® . • Assembly Guide : for every diameter it is delivered with the Transair ® pipes or fittings. • CE Certificate : Transair ® conforms the European Pressure Equipment Directive 2014/68/UE for article 4.3 and category I. Please contact Parker Transair for the latest version. • ISO 9001 Certificate : this document has a validity date. Please contact Parker Transair for the latest version. • Material Certificate 3.1 for Aluminium Pipes: it attests the conformity of the aluminium used (according to NF EN 10204). Ask for this document when placing the order. If needed you can also request it after delivery with the batch number marked on the pipes (see example on this picture). • Material Certificate for Fittings: the certificate 2.2 attests the qual- ity checks completed during production (according to NF EN 10204). Ask for this document when placing the order, it can’t be issued after as the name of the client and the order number have to be indicated on the certificate. • Isometric Plan of the System: if needed, the Transair ® quotation service can help you providing a drawing of the net- work (transair.quotation@parker.com ). • Calculation Note: Transair ® aluminium pipes are produced according to EN 10217-7, which defines the mechanical characteristics, and the TÜV certificate includes control of the design and of the safety factors. For further information, please contact Parker Transair. For the Transair ® system, the category is defined according to the diameter and the working pressure: 1 bar 7 bar 10 bar 13 bar 16 bar Ø16.5 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Ø25 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Ø40 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Ø50 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Ø63 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Ø76 Article 4.3 Article 4.3 Article 4.3 Article 4.3 Category I Ø100 Article 4.3 Article 4.3 Article 4.3 Category I Category I Ø168 Article 4.3 Category I Category I Category I Category I Installation Guide
