Umfang (scope):
This part of prEN 10219 specifies the technical delivery conditions for electric welded and submerged arc welded cold formed structural steel hollow sections of circular, square, rectangular or elliptical forms and applies to structural hollow sections formed cold without subsequent heat treatment. The general conditions (product characteristics, test methods and performance criteria that apply under the Construction Products Regulations) are specified in prEN 10219-1 and the requirements for tolerances, dimensions and sectional properties in prEN 10219-3. NOTE 1 prEN 10219-1 covers provision of the Construction Products Regulations (CPR) to fulfil European law for construction products. The technical delivery conditions are described within prEN 10219-2 in combination with Clauses 2, 3, 4, 5, 7 and 8 of prEN 10219-1. NOTE 2 The attention of users is drawn to the fact that whilst cold formed grades in prEN 10219-2 can have equivalent mechanical properties to hot-finished grades in prEN 10210-2 the sectional properties of square and rectangular hollow sections in prEN 10219-3 and prEN 10210-3 are not equivalent. NOTE 3 A range of steel grades is specified in this European Standard and the user should select the grade most appropriate to the intended use and service conditions. The grades and mechanical properties, but not the final supply condition of cold formed hollow sections are comparable with those in EN 10025-2, EN 10025-3, EN 10025-4, EN 10025-5, EN 10025-6, EN 10149-2 and EN 10149-3. NOTE 4 Hollow sections for offshore structures are covered in EN 10225.
