a - If, in the case of strip in rolling widths < 300 mm, longitudinal test pieces are taken, the minimum values are reduced as follows:
- proof strength - minus 15 MPa,
- elongation for constant gauge length - minus 5 %;
- elongation for proportional gauge length - minus 2 %.
For continuously hot rolled products, 20 MPa higher minimum values of Rp0,2 and 10 MPa higher minimum values of Rp1,0 may be agreed at the time of enquiry and order.
