13.6.2 Inspection personnel The manufacturer shall ensure that all personnel selected to carry out inspection have received adequate training. Training records shall be retained and shall be made available for examination when required.
13.6.3 Non-destructive inspection method Visual inspection shall be carried out in accordance with EN 970. Where, on visual inspection, the presence of surface breaking, cracking or lack of fusion is suspected, penetrate testing in accordance with EN 571-1 shall be carried out by agreement. The method of inspection shall be appropriate to the types and locations of weld discontinuities being assessed.
13.6.4 Destructive inspection Where verification of the results of non-destructive testing is considered necessary any sectioning and examination criteria shall be agreed.
13.7 Design verification Design shall be based on the loads specified in EN 40-3-1 and shall be verified either by testing to EN 40-3-2 or by calculation to prEN 40-3-3.
13.8 Verification of corrosion protection
13.8.1 Hot dip galvanizing Where hot dip galvanizing is specified the protection treatment shall be visually inspected. The thickness of coating on areas A and B shall be measured in accordance with EN ISO 1461. NOTE ISO 1463 describes a microscopical method for measuring coating thickness.
13.8.2 Thermal spraying with metal Where thermal spraying is specified the protection treatment shall be visually inspected and the thickness of the deposited metal shall be measured in accordance with ISO 2063 (see A.2). NOTE ISO 1463 describes a microscopial method for measuring coating thickness.
13.8.3 Phosphating and painting Where phosphating and painting is specified the protection treatment shall be visually inspected and the thickness of the phosphate coating shall be measured in accordance with ISO 9717.
13.8.4 Painting Except for hot dip galvanized surfaces before any paint coating is applied, the external surfaces (areas A and B) shall be checked by comparator for compliance with grade Sa 2½ in accordance with ISO 8501-1. 13.9 Identification verification The marking shall be checked to confirm correct identification. 13.10 Records Details of all materials, processes and procedures used and details of sampling and testing and personal training records shall be recorded and retained for a minimum of seven years and made available for examination when required.
14 Acceptance criteria
14.1 General requirement The lot shall be deemed acceptable, provided all the relevant requirements are met by all the articles in the control sample.
14.2 Dimensions All applicable dimensions of the checklist given in 13.3 shall be within the specified tolerances.
14.3 Straightness Method A: When verified by method A in 13.4 no measurement between the line and the column shall exceed that calculated for the column length in accordance with 5.1 of prEN 40-2:1999. Method B: When verified by method B in 13.4 it shall not be possible for both ends of the gauge to be in contact with the column at any location.
14.4 Material Verification shall confirm that the material specification and nominal thickness are not less than those specified in the design.
14.5.1 Welding and inspection personnel Test results for welders as required in 7.3, and training records as required in 13.6.2 shall be kept current and made available for review on request.
14.5.2 Welds Welding surfaces shall be free from sharp edges, spatter and contaminants. The throat dimensions of butt welds and the leg length and apparent throat dimensions of fillet welds, as measured by welding gauge and taking into account lack of fit, shall not be less than those specified except that local shortfalls of up to 0,5 mm shall be accepted provided the average over any length is not less than the specified dimensions. The external toe angle shall not be less than 110°. The surface of all welds shall be free from cracks and lack of fusion including overlap. Isolated discontinuous porosity will be accepted provided it is not detrimental to the surface protection to be provided. Undercut shall not result in a section loss of more than 5 % over any 50 mm length of joint, nor shall its depth exceed 0,5 mm or 10 % of the design thickness, whichever is the less. Work shall be deemed acceptable when the above criteria are met.
14.5.3 Non-destructive inspection If the additional non-destructive inspection checks reveal satisfactory welds then the lot shall be deemed acceptable. Where surface breaking porosity, cracking, lack of fusion, lack of penetration or gross internal porosity is confirmed by follow-up penetrant testing according to EN 571-1, the columns shall be deemed to fail. Clause 15 shall apply to the status of the lot.
