This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2001, and conflicting national standards shall be withdrawn at the latest by January 2001. According to the CENKENELEC Internal R
13、egulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherands, Norway, Portugal, Spain, Sweden, Switzerland and th
14、e United Kingdom. This European Standard is composed of the two f0llOWing parts: - Part 1 : Pressurized components; - Part 2: Non internal pressurized components. Page 3 EN 1708-2 : 2000 1 Scope The purpose of this European Standard is to exemplify sound and accepted welded connections applicable to
15、 welded not internal pressurized steel components. It does not promote the standardization of connections that may be regarded as mandatory or restrict development in any way. The requirements of carrying capacity, fitness for purposes, fatigue and corrosion stress are to be considered if necessary.
16、 This standard contains examples of connections welded by the following processes (process numbers according to EN IS0 4063): - Manual metal arc welding (1 11); - self-shielded tubular-cored arc welding (1 14); - Submerged arc welding (12); - MIG welding; Metal inert gas welding (131); - MAG welding
17、; Metal active gas welding (1 35) - Tubular cored metal arc welding with active gas shield (136); - Tubular cored metal arc welding with inert gas shield (137); - TIG welding; Tungsten inert gas arc welding (141) Other processes by agreement. Further requirements should be considered in accordance w

These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references
