Essais destructifs des soudures sur matOrlaux mOtalllques — Essais de pliage.
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) See Figures 1, 2 and 9.
For transverse root and face bend tests, the test specimen thickness, ,, shall be equal to the thickness of the base material adjacent to the welded joint up to a maximum thickness of 30 mm. If the test piece thickness, t, is greater than 10 mm, the test specimen thickness, :, may be machined or otherwise mechanically finished from one side to a thickness equal to (10 ± 0.5) mm as indicated in Figures 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 Figure 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 of a butt weld (SBB)
See Figures 3 and 10.
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. s. of at least (10 ± 0,5) mm. unless otherwise specified in the relevant application standard,
When the joint thickness exceeds 40 mm, it is permissible to split the specimen in the plane of the test piece thickness as shown in Figure 10. In these cases the location of the test specimen in the welded joint thickness shall be identified.
5.6.3 Longitudinal bend tests of a butt weld (LFBB and LRBB) See Figure 4.
For longitudinal bend tests, the test specimen thickness, r. shall be equal to the thickness of the base
material near the welded joint, but should not exceed 10 mm. If the test piece thickness, :, is greater than
10 mm, the test specimen thickness, l, 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.ISO 5173-2009 pdf free download.
