Scope

This part of IEC 61366 gives guidelines for the content and structure of technical specifications and related tendering documentation for pump‑turbines, covering the information employers should provide, the technical data and contractual clauses suppliers should respond to, and the evaluation criteria to be used when assessing tenders. It is intended to be used alongside the general Part 1 guidance and the other machine‑specific parts in the IEC 61366 series.

Key topics and requirements

• Recommended structure and content for Tendering Documents (technical specifications, instructions to tenderers, required appendices and data sheets).
• Definition of design and hydraulic conditions and the technical data to be supplied by the owner.
• Performance guarantees, acceptance criteria and procedures for hydraulic and mechanical tests (including site and factory tests where applicable).
• Mechanical design criteria, materials, corrosion protection and inspection/test requirements specific to pump‑turbines.
• Contractual limits of supply, responsibilities for tests, spare parts, documentation, installation, commissioning and training.

Typical use and users

Used by project owners, utilities, consulting engineers, procurement teams, manufacturers and contractors involved in the specification, tendering, manufacture and acceptance testing of pump‑turbines. It is a practical procurement tool for preparing clear, comparable tender packages and evaluating contractor offers.
