22、in 3.2 and 3.3. The selection of materials should take account of the intended use and all reasonably foreseeable operation conditions. Selecting materials from Group 1 will provide some assurance of their suitability for valve bodies, bonnets and covers, whereas selecting from Group 2 will not prov
23、ide the same assurance. Due consideration should be given to all reasonably foreseeable degradation mechanism (e.g. corrosion, creep, fatigue) that may occur in some applications. 3.2 Group 1 materials EN 12516-4:2014, Table 8, lists copper alloys specified in European material standards which have
