The purpose of this document is to establish, in a general way, suitable procedures for commissioning and operation of hydraulic machines and associated equipment, and to indicate how such machines and equipment should be commissioned and operated. Commissioning and operation of the associated equipment are not described in detail in this document but is considered in the commissioning and operation procedure as a separate step. Machines of up to about 15 MW and reference diameters of about 3 m are generally covered by IEC 62006. It is understood that a guideline of this type will be binding only if the contracting parties have agreed upon it. The guidelines exclude matters of purely commercial interest, except those inextricably connected with the conduct of commissioning and operation. The guidelines are not concerned with waterways, gates, drainage pumps, cooling-water equipment, generators, motor-generators, electrical equipment (e.g. circuit breakers, transformers) etc., except where they cannot be separated from the hydraulic machinery and its equipment. Wherever the guidelines specify that documents, drawings or information are supplied by a supplier (or by suppliers), each individual supplier should furnish the appropriate information for its own supply only.
