21、e purposes of this document, the terms, definitions and symbols given in EN 4259 apply. 4 Health and safety Resources, test pieces, test samples, test materials, test equipment and test procedures shall comply with the current health and safety regulations/laws of the countries where the test is to

22、be carried out. Where materials and/or reagents which may be hazardous to health are specified, appropriate precautions in conformity with local regulations and/or laws shall be taken. 5 Principle A test piece with a sharp machined notch is tested in tension to determine the maximum force (or load,

23、P) that can be withstood. The ratio of sharp notch strength to 0,2 % proof stress is used as a comparative index of fracture toughness. The test method is restricted to those materials (e.g. aluminium and magnesium alloys) in which the required sharp notch may be machined. 1) Published as ASD-STAN P

29、accordance with the technical specifications; identification and traceability of test samples taken from the semi-finished product (e.g. location, orientation, size); identification and traceability of test pieces taken from the test samples (e.g. number, preparation, method, conditioning, use/metho

30、d of mechanical straightening of coiled strip). In certain cases, the test piece may be the test sample: expression of results (e.g. individual values or mean values, units, if fracture outside middle third of gauge length, use of an extensometer to measure elongation after fracture, unusual feature

31、s in the fracture surface, .); recorded plots/graphs, when necessary; date of test; traceability of individual performing the test; any incident which may have affected the results; any deviation from the test method standard.
