This Video is to explain Through thickness tensile testing, Zed-testing of rolled steel. apply to plates and wide flats with thickness 15 mm and over with specified minimum through thickness Zed direction properties. Zed-grade steels are typically used to minimise the possibility of lamellar tearing, during fabrication by welding.
Sampling for Testing
For sections, wide flat the sample shall be taken from one end of the product. The sampling position shall be the flange. The location of the sample is indicated in Figure
For flat products the sample shall be taken from one end of the product.
Test material shall be taken close to the longitudinal centreline from one end of each rolled piece representing the test unit.
The test material shall be large enough to accommodate the preparation of six test specimens. Three test specimens shall be prepared while the rest of the sample remains for possible retest.
The cross-section of each specimen shall be sufficient to permit the removal of any resultant heat affected or work hardened zone during machining of the final test pieces.
Test pieces with or without extension pieces is subject to following condition
