27、l requirements for the hydraulic machine for which the Tendering Documents (TD) are being issued. To achieve clarity and to avoid confusion in contract administration, the Employer should not specify anything in the technical specifications which is of importance only to the preparation of the tende
28、r. Such information and instructions should be given only in the instructions to Tenderers (ITT). Accordingly, the ITT may refer to other chapters and sections of the Tendering Documents but not vice versa. As a general rule the word “Tenderer” should be confined in use only to TD chapter 1 “Tenderi
29、ng requirements”; elsewhere the term “Contractor” should be used. Special attention should be given to items of a project specific nature such as materials, protective coating systems, mechanical piping systems, electrical systems and instrumentation. It is common for the Employer to use technical s
30、tandards for such items which would apply to all contracts for a particular project or projects. In this event, detailed technical standards should be specified in TD chapter 5 “General requirements”. Technical specifications for the various types of hydraulic machines included in this guide are pro
31、vided in the following parts: Francis turbines (Part 2); Pelton turbines (Part 3); Kaplan and Propeller turbines (Part 4); Tubular turbines (Part 5); Pump-turbines (Part 6); Storage pumps (Part 7). The guidelines for preparation of Kaplan and propeller turbine specifications include technical specif
32、ications for the following. Design conditions: project arrangement, hydraulic conditions, specified conditions, mode of operation, generator characteristics, synchronous condenser characteristics, transient behaviour data, stability of the system, noise, vibration, pressure fluctuations and safety r

Site installation and commissioning tests: installation procedures and commissioning tests. Field acceptance tests: scope of field tests, test measurement methods, reports and inspection of
42、 cavitation pitting. An example of the proposed table of contents for Tendering Documents for a Francis turbine is given in Annex A. The example does not include technical specifications for the control system, relief valves, or high and low-pressure side valves or gates which, at the Employers opti
43、on, may be included in the Tendering Documents for the Kaplan and propeller turbine or may be specified in separate documents. Chapter 6 (technical specifications) of the Tendering Documents should be arranged as follows: 1 Scope This technical report, referred to herein as the Guide, is intended to
