Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard uses the translation method identical with ISO 9017.2001 "Destructive tests on welds in metallic materials fracture test." For ease of use, combined with China's actual situation of the standard made the following editorial changes. --- Deleted international standards foreword; --- The ISO 9017. ISO 2001 standards referenced in place of using the equivalent of the standard; --- Table 1 made editorial changes.

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Inspection length Lf examinationlength Subject to any length between the two sides of notched specimens along the weld axis (see Fig. 6). 3.2 Test total length ΣLf totalexaminationlength The sum of the length of the specimen between any two sides of a subject all samples notched along the weld axis (see FIG. 6). 3.3 Test thickness af examinationthickness The thickness of each specimen fracture surface (see Figures 7 and 8). 3.4 Inspection area Af examinationarea Subject area of \u200b\u200beach sample, the thickness inspection and testing is generally the length of the product. 3.5 The total testing area ΣAf totalexaminationarea The sum of all of the test area.

4 General principles

Using a method of stretching or bending, welding by applying static load or dynamic load it off in the weld in order to test the fracture surface, in order to lead Hair breakage can change the gap size and temperature. Unless otherwise specified, the test is at ambient temperature 23 ℃ ± 5 ℃ conditions.

5 symbols and legend

Table 1 defines the symbols and statements used in fracture tests, Figs. 5 to 8 are given the appropriate sample.
