Where panels have been produced by zinc or zinc alloy coating after fabrication the coated panels shall comply with the requirements of EN ISO 1461. Where mesh in panels coated after fabrication contains two diamet

45、ers of wire, the coating mass shall not be less than the average of the specified minimum values of the two diameters. 6.3.2 Organic material coatings When present, organic material coatings shall comply with the appropriate part of EN 10245-1 and EN 10245-2 or EN 10245-3. 6.4 Tolerance on mesh dime

47、The variation in the mesh spacing shall provide a maximum cumulative variation of 5 mm per meter. 6.5 Weld shear strength When tested in accordance with Annex A the average of all the four loads shall not be less than 75 % of the wire breaking load of the smallest diameter wire. NOTE Breaking load i

48、s the maximum force during the tensile test before breaking. If the average fails to meet this requirement, all the welds across the specimen shall be tested. The mesh shall be deemed acceptable if the average of all the weld shear test values across the specimen is greater than 75 % of the wire bre
