Full title and description

STB BS IEC 61366-7:1998 — Hydraulic turbines, storage pumps and pump‑turbines — Tendering documents — Part 7: Guidelines for technical specifications for storage pumps. This document is the IEC technical report giving model wording, recommended specification content and evaluation guidance to assist preparation and assessment of tendering documents for storage (pumped‑storage) pumps; it is published by IEC and adopted as a British Standard (BS IEC 61366‑7:1998).

Abstract

This part of IEC 61366 is a technical report intended to help owners, engineers and procuring authorities prepare clear, consistent and complete tendering documents and to evaluate tenders for storage pumps used in pumped‑storage and related hydraulic installations. It covers recommended specification clauses, performance and test requirements, documentation and acceptance criteria to reduce ambiguity and support fair tender evaluation.

General information

• Status: Published technical report; adopted as a British Standard (identical adoption). Stable/monitored.
• Publication date: IEC TR published 11 March 1998; BSI adoption published 15 September 1998.
• Publisher: International Electrotechnical Commission (IEC); adopted/published as BS IEC by the British Standards Institution (BSI).
• ICS / categories: 27.140 — Hydraulic energy engineering.
• Edition / version: Edition 1.0 (IEC TR 61366‑7:1998).
• Number of pages: IEC TR: 32 pages (original IEC publication); British adoption listing commonly shows 26 pages for the BS reprint — presentational differences may account for the variance.

Scope

The report provides guidance for preparing tendering documents and technical specifications specifically for storage (pumped‑storage) pumps within the hydraulic turbines, storage pumps and pump‑turbine family. It addresses specification structure, essential contractual clauses, guaranteed performance figures, test and inspection requirements, documentation to be supplied by the manufacturer, installation and commissioning criteria and acceptance test procedures appropriate for storage pump procurement. The aim is to promote clear requirements and consistent tender evaluation.

Key topics and requirements

• Recommended structure and wording for tender and contract technical specifications.
• Performance requirements and guaranteed values (head, flow, efficiency, speed, cavitation limits).
• Factory and on‑site tests (type, routine and performance tests) and acceptance criteria.
• Documentation and drawings to be submitted with tenders and prior to acceptance.
• Site installation, commissioning and responsibility allocation between purchaser and supplier.
• Evaluation guidance to compare tenders objectively and to deal with deviations/alternatives.

Typical use and users

Used by utilities, hydro project owners, procurement officers, consulting engineers, contract authors, manufacturers of storage pumps, test laboratories and regulatory bodies involved in specification, tendering, manufacture, testing and acceptance of pumped‑storage equipment. It is intended to be a practical drafting and evaluation aid rather than a prescriptive design standard.

Related standards

Commonly referenced standards and documents include other parts of the IEC 61366 series and standards for hydraulic machines and acceptance/testing such as IEC 60193 (model acceptance tests for hydraulic turbines and pump‑turbines) and later standards on rehabilitation and performance (for example IEC/EN 62256 series). National adoptions and related EN/BS documents on hydraulic machinery testing and rehabilitation are also relevant when preparing contracts and acceptance tests.

FAQ

Q: What is this standard?

A: It is IEC TR 61366‑7:1998 — a technical report giving guidelines for technical specifications and tendering documents for storage (pumped‑storage) pumps; it was adopted identically as BS IEC 61366‑7:1998.

Q: What does it cover?

A: It covers recommended specification clauses, required documentation, performance and test requirements, acceptance criteria, and guidance for preparing and evaluating tenders for storage pumps used in pumped‑storage and related installations.

Q: Who typically uses it?

A: Procurement teams, hydro project owners, consulting engineers, contract specifiers, pump manufacturers and test houses involved in the tendering, manufacture, testing and acceptance of storage/pumped‑storage pumps.

Q: Is it current or superseded?

A: The IEC webstore lists IEC TR 61366‑7:1998 as edition 1.0 (publication March 11, 1998) with stability monitoring noted; national catalogues list the BS adoption from September 15, 1998. Users should check with IEC or their national standards body for any subsequent revisions or newer related standards, but the TR remains the authoritative 1998 guidance unless explicitly replaced.

Q: Is it part of a series?

A: Yes — it is Part 7 of the IEC 61366 series (Hydraulic turbines, storage pumps and pump‑turbines — Tendering documents). Other parts of the series address tendering documents for related machine types and procurement topics.

Q: What are the key keywords?

A: Hydraulic turbines; storage pumps; pump‑turbines; tendering documents; technical specifications; procurement; acceptance tests; IEC TR; BS IEC.
