The responsible German body involved in its preparation was the Normenausschuss Armaturen (Valves Standards Committ
4、ee), Technical Committee NA 003-00-25 AA Sanitrarmaturen. Amendments This standard differs from DIN EN 817:1997-10 as follows: a) The standard has been editorially revised. b) The designation system has been extended to include now nominal sizes and . c) Dimensional specifications have been extended
5、 and rearranged: Inlet dimensions (Table 3) Outlet dimensions (Table 4) Mounting dimensions (Table 5) and Special cases (6.5). d) Specifications regarding sensitivity have been extended to include performance levels (Table 11). e) The test regarding the torsional strength of operating mechanisms has
6、 been described in more detail (Clause 11). f) In Clause 14 “Acoustic characteristics”, flow rate class Z has been added (see Table 14).
