| a. For wall thickness greater than 60 mm the mechanical properties are subject to agreement.
b. See 11.2. c. l = longitudinal t = transverse d. Option 4: Additionally, longitudinal impact strength shall be verified at -10 °C e. Tubes made to these material grades are unlikely to support the essential requirements of Directive 97/23/EC unless other criteria are taken into account, see Annex I section 7.5 of this Directive * 1 MPa = 1 N/mm2 |
