5.5.2 Steel
Shearing shall not he used for thicknesses > 8 mm. If thermal cutting or other cutting methods which could affect the cut surfaces are used to extract the test specimen from the welded plate, or from the test piece, the cuts shall be made at a distance a 3 mm from the test specimen but In any case sufficient (depending on the process used) not to introduce metallurgical effects which could affect the test results
5.5.3 Other metallic materials
Sheared or thermal cut surfaces are not permitted on bend specimens; only machining (e.g. sawing.
grinding or milling) shall be used.
5.6 SpecImen sIze
5.6.1 Transverse root and face bend tests of a butt weld (TFBB and TRBB) SeeEiijmU.,2and9.
For transverse root and face bend tests, the test specimen thickness, t5, shall be equal to the thickness of the base material adjacent to the welded joint up to a maximum thickness of 30 mm. lithe test piece thickness, t, is greater than 10 mm, the test specimen thickness, t, may be machined or otherwise mechanically finished from one side to a thickness equal to (10 t 0.5) mm as Indicated in Ftgures 1 and 2. The face or root of the weld shall be in tension when the specimen is bent
When a relevant application standard requires testing of a full thickness > 10 mm, several test specimens may be taken in order to cover the full thickness of the joint as indicated in F4ure 9.
In such cases, the location of the test specimen in the welded joint thickness shall be identified.
5.6.2 Transverse side bend tests ala butt weld (SHH)
See F and J..
For side bend tests, the test specimen width. b, shall be equal to the thickness of the base material of the welded joint. The specimen shall have a thickness, c, of at least (10 ± 0.5) mm, unless otherwise specified In the relevant application standard.
When the Joint thickness exceeds 40mm, it is permissible to split the specimen in the plane of the test piece thickness as shown in Fgurc1fl. In these cases the location of the test specimen In the welded joint thickness shall he identified.
5.6.3 Longitudinal bend tests of a butt weld (LFBB and LRBB) See EigureA.
For longitudinal bend tests, the test specimen thickness. t5, shall be equal to the thickness of the base material near the welded joint, hut should not exceed 10 mm. lithe test piece thickness, t, is greater than 10 mm, the test specimen thickness, to may be machined or otherwise mechanically finished from one side to a thickness equal to (10 ± 0.5) mm as indicated in Figure 4. The face or root of the weld shall be in tension when the specimen is bent.
5.6.4 Face bend tests of cladding material without a butt weld (FBC).
8 Test report
The test report shall include at least the following information:
a) reference to this International Standard. i.e. ISO 5173:2009;
b) identification of the test specimen (marking, type of base material, heat treatment, etc.); c) shape and dimensions of the test specimen:
d) type and symbol of bend test (root and face, transverse or longitudinal, side transverse bend test);
e) conditions of testing (see Clause 6):
— test methods (former or roller);
— diameter of the former:
— distance between rollers.
f) testing temperature if not in the temperature range (23 ± 5) C;
g) type and dimensions of imperfections observed:
h) bending angle,
An example of a typical test report is given in Annex A.
