Technical specifications for centrifugal pumps. Class I

2Scope / Description

1.1 This International Standard covers the Class I
(most severe) requirements for centrifugal pumps
used in various industries. It consists of a basic text
covering general requirements. The technical
requirements refer only to the pump unit.
Storage pumps are not included in this
International Standard. A separate standard will be
issued by IEC.
The requirements of this International Standard
do not apply to centrifugal pumps used in
petroleum, petrochemical and natural gas
applications. The requirements for centrifugal
pumps used in these applications are given in
ISO 13709.
1.2 This International Standard includes design
features concerned with installation, maintenance
and safety of such pumps, including baseplate,
coupling and auxiliary piping.
1.3 Where this International Standard specification
has been called for:
a) and requires a specific design feature,
alternative designs may be offered which meet
the intent of this International Standard,
provided that the alternative is described in
detail;
b) pumps not complying with all requirements of
this International Standard may be offered for
consideration, provided that all deviations are
stated.
