The definitions of these respective fusion welding methods are given in 4.2 of ISO 857-1:1998. Welding can be performed with or without the addition of filler metal in accordance with one of the routes as specified in Table 1. Unless Option 2 is specified, the manufacturing process and/or route are at the discretion of the manufacturer. Option 2: The tube manufacturing process and/or route is specified by the purchaser. The finished tubes shall not include welds used for joining together lengths of the hot or cold rolled strip prior to forming. Option 3: (see Table 1). Option 4: (see Table 1). 7.2.2 Welding shall be carried out by qualified personnel in accordance with operating procedures. When tubes are being used for pressure equipment in categories II, III, and IV, (of Directive 97/23/EC) the operating procedures and the personnel shall be approved by a notified body in accordance with Article 12 or recognised third party organization in accordance with Article 13 of the Directive.

If heat treatments different from, or additional to, the reference heat treatment, are to be carried out after the delivery of the tubes, the purchaser may request, at the time of enquiry and order, additional mechanical tests on samples, that have been given heat treatments different from or additional to, those given in Tables 6 and 7. The heat treatment of the samples and the mechanical properties to be obtained from tests on them shall be agreed between the purchaser and the manufacturer at the time of enquiry and order. Option 7: Additional mechanical tests on samples, which have undergone a different or additional heat treatment, shall be carried out. Option 8: Impact test shall be carried out at room temperature (see Tables 6 and 7).
