41、ion of inspection and testing requirements 5.1 General The fabricator and/or installer shall be responsible for carrying out the testing, examinations and certification specified in this European Standard, for all piping fabricated to EN 13480-4. These requirements are specified in clauses 6 to 10.
42、Where required in the technical specification, additional examination and testing shall be performed. NOTEFor guidance on the use of conformity assessment procedures see CEN/TR 13480-7. 5.2 Classification of piping Industrial piping shall be classified in accordance with EN 13480-1:2002, Table 4.1-1
43、. EN 13480-5:2002 (E) Issue 1 (2002-05) 7 NOTE 1Piping classes I to III are identical to categories I to III of the Pressure Equipment Directive. NOTE 2The requirements for classification of industrial piping that is to be installed in a Member State of the EU and which is covered by the scope of th
44、e Pressure Equipment Directive and the appropriate conformity assessment are given in the Pressure Equipment Directive. 5.3 Testing and inspection procedures Testing and inspection shall be carried out by personnel trained for the method used. European Standards or written procedures (if necessary)
45、detailing the method and acceptance criteria shall be available to all testing personnel and inspectors. Records shall be kept to demonstrate that all required testing and inspection have been carried out and that the results are acceptable. 6 Design validation 6.1 Objective and extent Before fabric
46、ation/installation commences, a validation of the piping design and its supports shall be performed. The validation shall be carried out independently from the team that prepared the design, and independent from fabrication/installation. The design validation includes the pressure walls to the first
47、 joint with other pressurised components. It also includes the interaction with components directly connected to the piping, but does not include validation of the components themselves. The design validation shall be performed to verify that the piping meets the requirements of this European Standa
48、rd with regard to materials, design details and dimensions, and that the requirements of procedures and personnel can be met during fabrication. Where the design of parts has already been validated in accordance with this European Standard, and where an appropriate certificate or assessment report i
49、s available, a further design validation shall not be required. 6.2 Documentation 6.2.1 General Documentation shall be provided to demonstrate compliance with this European Standard and shall include construction drawings, parts lists, design calculations and the technical schedule for fabrication/installation. 6.2.2 Design calculations 6.2.2.1Where calculations are performed by hand or with the aid of a computer, the following minimum data shall
