IEC TR 61366-5-1998 PDF

Full title and description

Hydraulic turbines, storage pumps and pump‑turbines — Tendering Documents — Part 5: Guidelines for technical specifications for tubular turbines. This IEC Technical Report provides guidance to owners, consultants, manufacturers and procuring authorities to prepare consistent tendering documents, to structure technical specifications for tubular (tube) turbines and to evaluate tenders for such machines.

Abstract

IEC TR 61366‑5:1998 is a guidance document (technical report) that assists in preparation of tendering documentation, tender proposals and in the evaluation of tenders specifically for tubular turbines. It recommends the content and arrangement of technical specifications and identifies the technical information, tests and contractual items typically required to fairly compare and assess bids for tubular turbine contracts.

General information

• Status: Published (IEC Technical Report).
• Publication date: 11 March 1998.

• ICS / categories: 27.140 — Hydraulic energy engineering.
• Edition / version: Edition 1.0 (1998).
• Number of pages: 31 pages.

Scope

The report provides guidelines for drafting the technical specification sections of tendering documents for tubular turbines, including recommended formats for technical data sheets, required guaranteed data, test and acceptance requirements, documentation and commissioning provisions. It is intended to be used together with the general part of the IEC 61366 series and references established test and acceptance codes (for example IEC 60041 and related model/acceptance test codes) when specifying performance, field tests and model tests for hydraulic machines.

Key topics and requirements

• Recommended structure and contents of tendering documents and technical specifications for tubular turbines (technical data sheets, drawings, guaranteed values).
• Performance requirements and definition of guaranteed hydraulic performance, operating ranges and acceptance criteria.
• Testing and acceptance: model tests, field acceptance tests and references to relevant IEC test codes (e.g., IEC 60041, IEC 60193 where applicable).
• Mechanical, material and manufacturing requirements, inspection and quality assurance provisions.
• Documentation, drawings, packing, transportation, installation and commissioning requirements to be included in tenders.
• Instructions for tenderers, evaluation principles and contractual/performance guarantees to ensure comparable bids.

Typical use and users

Primarily used by owners/operators of hydroelectric plants, procuring utilities, consulting engineers preparing tender documents, turbine manufacturers preparing bids, contract managers and test laboratories involved in acceptance testing and commissioning of tubular turbines.

Related standards

Commonly used together with IEC and industry test/acceptance standards such as IEC 60041 (field acceptance tests to determine hydraulic performance), IEC 60193 (model acceptance tests) and IEC 60308 (testing of speed‑governing systems). IEC TR 61366‑5 is one part of the IEC TR 61366 series (parts addressing general arrangements and other turbine types — e.g., Parts 1–7 covering general guidance, Francis, Pelton, Kaplan/propeller, tubular, pump‑turbines and storage pumps).

Keywords

FAQ

Q: What is this standard?

A: IEC TR 61366‑5:1998 is a technical report from IEC that gives guidelines for preparing technical specifications and tendering documents specifically for tubular (tube) turbines used in hydroelectric projects.

Q: What does it cover?

A: It covers recommended content and arrangement of tendering documents and technical specifications, the technical data and guaranteed values to request, recommended tests and acceptance criteria, documentation and commissioning requirements, and evaluation guidance to enable fair comparison of tenders.

Q: Who typically uses it?

A: Owners/operators, consulting engineers, procurement teams, turbine manufacturers and test/inspection bodies involved in hydro turbine contracts and commissioning.

Q: Is it current or superseded?

A: The report was published on 11 March 1998 and is listed as a published IEC Technical Report; the IEC webstore shows its publication details and a stability indication through 2026. Users should confirm current status on the IEC webstore or their national standards body if they need the absolute latest status after 2026 or if a revision has been issued since then.

Q: Is it part of a series?

A: Yes — it is Part 5 of the IEC TR 61366 series (a multi‑part series providing general guidance and machine‑specific guidance for tendering documents for different types of hydraulic machines, e.g., Parts 1–7 covering general and specific turbine/pump types).
