适用范围：1 This International Standard covers dass II requirements for centrifugal pumps of back pull-out construction as used primarily in the Chemical and petrochemical industries. However the Standard, or individual clauses of it, can be ap-plied in other industries, for general industrial use or to pump designs other than of back pull-out construction.2 Pumps as specified in ISO 2858 are typical of those con-forming to this International Standard.3 This International Standard includes design features con-cerned with installation, maintenance and safety for these pumps, including baseplate couplings and auxiliary piping but excluding the driver.4 Where application of this International Standard nas been called fora) and a specific design feature is required, alternative designs which meet the intent of the Standard may be offered, provided that the alternative is described in detail;b) pumps not complying with all requirements of the Standard may be offered for consideration provided that all deviations are stated.5 Whenever the documents include contradicting technical requirements, they shall apply in the following sequence:a) purchase order (or enquiry if no order is placed) (see annexes F and G);b) data sheets (see annex A);c) this International Standard;d) other standards to which reference is made in the order or enquiry.
