The inner and outer surfaces of the tubes shall be clean and smooth. The inner surface of the tubes shall be capable of passing the reference residue test described in 8.5. The 2 residue left after the solvent has evaporated shall not exceed 38 mg/m of the inner surface. 6.6 Freedom from defects The tubes shall be free from defects that could be detrimental to their use. All tubes less than or equal to 42 mm diameter shall be subjected to the eddy current test described in 8.6. For tubes greater than 42 mm diameter, a method of non-destructive testing, if required, shall be agreed between the purchaser and the manufacturer. 7 Sampling For the purposes of demonstrating conformity to the dimensional requirements of this standard and the requirements of 8.1, 8.2 and 8.4, the sampling rate shall be at least one sampling unit for each 3 000 kg or for each production batch whichever is the smaller. NOTE Results may be used from analyses carried out at an earlier stage of manufacturing the product, e.g. at the casting or billets inward stage, if the material identity is maintained and if the quality management system of the manufacturer is certified as conforming to EN ISO 9001. w w w 8 Test methods 8.1 Analysis Analysis shall be carried out on the test samples obtained in accordance with clause 7. The analytical methods used shall be chemical or spectrographic in accordance with appropriate European or international standards. In cases of dispute, the reference method shall be by chemical analysis. 8.2 Tensile test The tensile test shall be carried out in accordance with the method given in EN 10002-1, on test pieces prepared from the test samples obtained in accordance with clause 7. 8.3 Hardness test When required, the Vickers hardness test shall be carried out in accordance with EN ISO 6507-1. © BSI 2006 Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Sun Nov 05 00:55:10 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 11 EN 12735-1:2001 8.4 Drift expanding test The drift expanding test shall be carried out in accordance with EN 10234. The outside diameter of the tube end shall be expanded by 30 % using a conical mandrel with an angle of 45°. 8.5 Residue test Use a minimum length of tube of 1 500 mm to perform the test. m o Close one end of the tube test piece and pour in suitable solvent, to one eighth of its capacity. Close the other end of the test piece and agitate the tube, in order to clean thoroughly the whole of its internal surface. Open one end of the tube and pour the solvent into a clean beaker. Open the other end to ensure all solvent is removed. Evaporate the solvent and dry the beaker in an oven at 100 °C to 110 °C for 10 min. Cool the beaker in a desiccator and weigh it. c . w x f z b . Carry out a blank test using the same quantity of solvent. Subtract the value obtained in the blank test from the value obtained in the residue test and calculate the mass per unit area of internal surface. The quantity of solvent used may vary with the size of the tube being examined. The quantity of solvent used for the blank test shall be the same as that used for the actual examination of the tube sample. For a reference test trichlorethylene shall be used. NOTE For routine controls in the course of quality assurance procedures, other methods may be used as an alternative. 8.6 Eddy current test The test shall be carried out in accordance with EN 1971. The reference standard tube shall contain holes produced from the drill diameters in Table 5. Table 5 — Drill diameters for reference standard tube Dimensions in millimetres Nominal outside diameter d over w w w 3 26 Drill diameter up to and including max. 26 0,8 42 1,2 Signals produced by reference standard tubes set the sorting limits for acceptance or rejection. Tubes containing defects which produce signals equal to or greater than the sorting limit shall be rejected. 8.7 Retests In the event that the tube sample fails to meet the test requirements, the batch represented by the tube sample or, in the case of continuous production, all tubes manufactured since the previous check, shall be placed in a bond. Further samples shall be taken from the bonded tubes at a sampling rate four times more frequent than specified in clause 7. If any of the retest samples fail to meet the specification requirements, the tubes represented by the samples shall be deemed not to meet the requirements of this standard and shall be rejected. If all the retest samples meet the requirements, the tubes represented by the samples shall be deemed to meet the requirements of this standard. © BSI 2006 Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Sun Nov 05 00:55:10 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 12 EN 12735-1:2001 9 Declaration of conformity and inspection documentation 9.1 Declaration of conformity !When requested by the purchaser [see 5 h)] and agreed with the supplier, the supplier shall issue for the products the appropriate declaration of conformity in accordance with EN 1655." 9.2 Inspection documentation m o ! When requested by the purchaser [see 5 i)] and agreed with the supplier, the supplier shall issue for the products the appropriate inspection document in accordance with EN 10204.

NOTE Plug design should be such to prevent the plug from being forced into the tube bore beyond its depth. The tubes shall be packaged in such a way that they are effectively protected in normal transport and handling conditions. The tubes shall be packaged in uniform batches, i.e. of the same dimensions and temper, and each package shall indicate at least the following information in a legible and indelible manner: — number of this standard (EN 12735-1); — nominal cross-sectional dimensions: outside diameter ´ wall thickness; — quantity; — temper; w w w — manufacturer’s identification mark. 10.2 Form of delivery Coiled tubes are usually supplied in 25 m or 50 m lengths. Straight tubes are usually supplied in 3 m, 5 m or 6 m lengths. © BSI 2006 Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Sun Nov 05 00:55:10 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 13 EN 12735-1:2001 ! Annex ZA (informative) Relationship between this European Standard and the Essential Requirements of EU Directive 97/23/EC m o This European Standard has been prepared under a Mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential Requirements of the New Approach Directive 97/23/EC. Once this standard is cited in the Official Journal of the European Communities under that Directive and has been implemented as a national standard in at least one Member State, compliance with the clauses of this standard given in Table ZA.1 confers, within the limits of the scope of this standard, a presumption of conformity with the corresponding Essential Requirements of that Directive and associated EFTA regulations. c . w x f z b . For this harmonized supporting standard for materials, presumption of conformity to the Essential Requirements of the Directive is limited to technical data of the material in the standard and does not presume adequacy of the material to specific equipment. Consequently the technical data stated in the material standard should be assessed against the design requirements of the specific equipment to verify that the Essential Requirements of the Pressure Equipment Directive (PED) are satisfied.
