8、andards Policy Committee and is the English language version of EN 22858:1993 End-suction centrifugal pumps (rating 16 bar) Designation, nominal duty point and dimensions, published by the European Committee for Standardization (CEN). It is identical with ISO 2858:1975, published by the Internationa
9、l Organization for Standardization (ISO). EN 22858:1993 was produced as a result of international discussion in which the UK took an active part. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct ap
10、plication. Compliance with a British Standard does not of itself confer immunity from legal obligations.
