NOTE1: The bold figures indicate the standard products which are suitable for most applications. The boxes without figures represent products which are outside the scope of t his standard. NOTE 2: For smaller DN, the minimum pipe wall thickness is governed by a combination of maufacturing constraints, structural performance and installation and handing requirements. NOTE 3: The minimum thickness is given for non-restrained joints(see 4.2). NOTE 4: Pressure classes between 50 and 100 may be supplied by interpolation on request.
