National foreword

This British Standard was prepared under the direction of the Mechanical Engineering Standards Committee and is identical with IEC Publication 545:1976 “Guide for commissioning, operation and maintenance of hydraulic turbines”.

Terminology and conventions. The text of the International Standard has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following.

The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker.

Wherever page numbers are quoted in connection with references to figures in this publication they are IEC page numbers (shown in brackets at the foot of each page).

Cross-references. At present there are no corresponding British Standards for the International Standards referred to.

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.

Cooperating organizations

The Mechanical Engineering Standards Committee, under whose direction this British Standard was prepared, consists of representatives from the following Government departments and scientific and industrial organizations:

The organizations marked with an asterisk in the above list, together with the following, were directly represented on the committee entrusted with the preparation of this British Standard:

Chapter I. General

1 Scope and object

The purpose of this guide is to establish, in a general way, suitable procedures for commissioning hydraulic turbines and associated equipment, and to indicate how such turbines and equipment should be operated and maintained.

It is understood that a publication of this type will be binding only if, and to the extent that, both contracting parties have agreed upon it.

The guide excludes matters of purely commercial interest, except those inextricably bound up with the conduct of commissioning, operation and maintenance.

The guide applies to impulse and reaction turbines of all types, and especially to large turbines directly coupled to electric generators. It applies also to pump-turbines when operating as turbines.

The guide is not concerned with water conduits, gates, valves, drainage pumps, cooling-water equipment, generators, etc., except where they cannot be separated from the turbine and its equipment.

Wherever the guide specifies that documents, drawings or information shall be supplied by a manufacturer (or by manufacturers), each individual manufacturer shall be required to furnish the appropriate information for his own supply only.
