Product Details
It also specifies the test parameters for the test methods referred to in this International Standard.
In conjunction with part of ISO 4437-1, ISO 4437-3, ISO 4437-4, and ISO 4437-5, it is applicable to PE pipes, fittings and valves, their joints, and joints with components of PE and other materials intended to be used under the following conditions: the maximum operating pressure (MOP) is based on the design stress determined from the compound minimum required strength (MRS) divided by the C factor, and taking into account rapid crack propagation (RCP) requirements; and a temperature of 20 °C is taken as reference temperature for the design basis.
ISO 4437-2:2014 covers three types of pipes: PE pipes (outside diameter dn) including any identification stripes; PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter dn), where all PE layers have the same MRS rating; and PE pipes (outside diameter dn) with a peelable and contiguous thermoplastics additional layer on the outside (coated pipe).
