BSI 04-1999,Foreword,This revision of BS 709:1971 has been prepared under the direction of the,Welding Standards Committee. It retains the general pattern of the 1971 edition,but has been modified to take into account developments in the international,field. This edition introduces an intercrystalline corrosion test, a fracture,toughness test and a test of hardness gradient across a weld. BS 709:1971 is,withdrawn.,The standard covers only routine approval tests normally required by application,standards. Tests for the susceptibility to lamellar tearing, re-heat cracking and,fatigue are therefore not included.,Standards relating to welded constructions in various branches of engineering,generally include requirements for certain welding tests to be conducted,primarily for the approval of welding procedures and operators. There is seldom,any technical reason for divergence from standard procedures to be followed for,such welding tests and there are both practical and economic advantages to be,gained in standardization. The main purpose of this standard is to describe test,procedures and to specify requirements for test specimens that should be quoted,or incorporated, in engineering application standards that deal with welded,constructions. Where differences still exist between application standards, the,methods of test given in this standard are to be preferred.,A general indication is given of the purpose served by each of the different tests,but the standard does not purport to lay down when any particular t……
