Standard history

The purpose of this guide is to establish, in a general way, suitable procedures and tolerances for the installation of bulb turbine and generator. This guide presents a typical assembly and whenever the words "turbine" and "generator" are used in this part, it refers to bulb turbine and generator. There are many possible ways to assemble a unit. The size of the machine, the design of the machine, the layout of the powerhouse, the sequence of concreting or the delivery schedule of the components are some of the elements that could result in additional steps, or the elimination of some steps and/or assembly sequences.
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 installation. It also excluded to specifications of the civil works but this aspect of the work should be taken into consideration during the assembly of the units.
Wherever the guide specifies that documents, drawings or information is supplied by a manufacturer (or by manufacturers), each individual manufacturer will furnish the appropriate information for their own supply only.
