This International Standard specifies methods for determining fracture toughness in terms of K (stress intensity factor), (crack tip opening displacement, CTOD), and J (experimental equivalent of the J-integral) for welds in metallic materials. This method is complementary to ISO 12135, which covers all aspects of fracture toughness testing of parent metal and which needs to be used in conjunction with this document. This standard describes methods for determining point values of fracture toughness. It should not be considered a method for obtaining a valid resistance-to-crack extension R-curve. However, the specimen preparation methods described in this standard could be usefully employed when determining R-curves for welds. This method uses fatigue precracked specimens which have been notched, after welding, into a specified target area in the weld. Methods are described to evaluate the suitability of a weld for notch placement within the target area which is either within the weld metal or the weld heat affected zone (HAZ) and then, where appropriate, to evaluate the effectiveness of the fatigue crack in sampling these areas.
