BUILDING INTERCOM SYSTEMS –
Part 1-2: System requirements –
Building intercom systems using the internet protocol (IP)
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in

addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses

arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTERNATIONAL ELECTROTECHNICAL COMMISSION
___________
HYDRAULIC TURBINES, STORAGE PUMPS AND PUMP-TURBINES –
TENDERING DOCUMENTS –
Part 5: Guidelines for technical specifications
for tubular turbines
FOREWORD

1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, the IEC publishes International Standards. Their preparation is

entrusted to technical committees; any IEC National Committee interested in the subject dealt with may

participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization

for Standardization (ISO) in accordance with conditions determined by agreement between the two

organizations.

2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an

international consensus of opinion on the relevant subjects since each technical committee has representation

from all interested National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical reports or guides and they are accepted by the National Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject

of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC technical committees is to prepare International Standards. In

exceptional circumstances, a technical committee may propose the publication of a technical

report of one of the following types:

• type 1, when the required support cannot be obtained for the publication of an International

Standard, despite repeated efforts;

• type 2, when the subject is still under technical development or where for any other reason

there is the future but no immediate possibility of an agreement on an International

Standard;

• type 3, when a technical committee has collected data of a different kind from that which is

normally published as an International Standard, for example "state of the art".

Technical reports of types 1 and 2 are subject to review within three years of publication to

decide whether they can be transformed into International Standards. Technical reports of

type 3 do not necessarily have to be reviewed until the data they provide are considered to be

no longer valid or useful.

IEC 61366-5, which is a technical report of type 3, has been prepared by IEC technical

committee 4: Hydraulic turbines.

Committee draft Report on voting
4/110/CDV 4/122/RVC

Full information on the voting for the approval of this technical report can be found in the report

on voting indicated in the above table.

Technical Report IEC 61366-5 is one of a series which deals with Tendering documents for

hydraulic turbines, storage pumps and pump-turbines. The series consists of seven parts:

Part 1: General and annexes (IEC 61366-1)

Part 2: Guidelines for technical specification for Francis turbines (IEC 61366-2)

Part 3: Guidelines for technical specification for Pelton turbines (IEC 61366-3)

Part 4: Guidelines for technical specification for Kaplan and propeller turbines (IEC 61366-4)

Part 5: Guidelines for technical specification for tubular turbines (IEC 61366-5)

Part 6: Guidelines for technical specification for pump-turbines (IEC 61366-6)
Part 7: Guidelines for technical specification for storage pumps (IEC 61366-7)

Parts 2 to 7 are "stand-alone" publications which when used with Part 1 contain guidelines for a

specific machine type (i.e. Parts 1 and 4 represent the combined guide for Kaplan and

propeller turbines). A summary of the proposed contents for a typical set of Tendering

documents is given in the following table 1 and annex A. Table 1 summarizes the arrangement

of each part of this guide and serves as a reference for the various chapters and sections of

TENDERING DOCUMENTS –
Part 2: Guidelines for technical specifications
for tubular turbines
0 Introduction to technical specifications

The main purpose of the technical specifications is to describe the specific technical

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 tender. 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 "Tendering 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 standards 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

provided in the following parts:
– Francis turbines (Part 2);
– Pelton turbines (Part 3);
– Propeller and Kaplan turbines (Part 4);
– Tubular turbines (Part 5);
– Pump-turbines (Part 6);
– Storage pumps (Part 7).

The guidelines for preparation of tubular turbine specifications include technical specifications

for the following:

– Design conditions: Project arrangement, hydraulic conditions, mode of operation, generator

characteristics, transient behaviour data, stability of the system, noise, vibration, pressure

fluctuations and safety requirements.
– Technical performance and other guarantees:
ypower;
ydischarge;
yefficiency;
ymaximum momentary pressure;
yminimum momentary pressure;
ymaximum momentary overspeed;
ymaximum steady-state runaway speed;

– 8 – 61366-5 © IEC:1998(E)
ycavitation pitting;
yhydraulic thrust;
ymaximum weights and dimensions for transportation, erection and maintenance.

– Mechanical design criteria: design standards, stresses and deflections and special design

considerations.
– Design documentation: Contractor’s input needed for the Employer's design, the

Contractor's drawings and data, Contractor's review of the Employer's design and technical

reports by Contractor.

– Materials and construction: material selection and standards, quality assurance procedures,

shop methods and personnel, corrosion protection and painting.

– Shop inspection and testing: general requirements and reports, material tests and

certificates, dimensional checks, shop assembly and tests.

– Fixed/embedded components: generator hatch cover or pit, stay ring, discharge ring (if

any), draft tube, draft tube liner foundations anchorage, upstream and downstream

pressure taps and pipes.

– Stationary/removable components: bulb nose, generator access shaft inner and outer guide

rings and guide vanes.

– Regulating apparatus: servomotor, counterweight, connecting rods, regulating ring, guide

vane linkage, system, guide vane overload protection and locking devices.

– Rotating parts, bearings and seals: runner, main shaft, guide bearing, main shaft seal, oil

head and runner blade regulation system with servomotor assembly with oil supply, linkage

system, crosshead and oilhead.

– Thrust and counter-thrust bearing: bearing support, thrust collar and counter-thrust bearing

pads and rings, oil sump and instrumentation.
– Gear box: gear box and related components.

– Miscellaneous components: walkways, platforms, lifting fixtures, special tools, standard

tools and nameplate.

– Auxiliary systems: water supply to main shaft seal, turbine drainage, lubrication-guide vane

regulating system, and oil supply to bearings.
– Instrumentation: controls, indication and protection.
– Spare parts: basic spare parts.
– Model acceptance tests: test requirements.

– Site installation and commissioning test: installation procedures and commissioning.

– Field acceptance tests: scope of field test scope and reports and inspection of cavitation

pitting.

An example of the proposed table of contents for Tendering documents for a Francis turbine is

given in annex A of IEC 61366-1. The example does not include technical specifications for the

control system, relief valves, or high and low pressure slide valves or gates which, at the

Employer's option, may be included in the Tendering documents for the turbine or may be

specified in separate documents.

Chapter 6 (technical specifications) of the Tendering documents should be arranged as follows:

6.1 Technical requirements;
6.2 Technical specifications for fixed/embedded components;
6.3 Technical specifications for stationary/removable components;
6.4 Technical specifications for guide vane regulating apparatus;
6.5 Technical specifications for rotating parts, guide bearings and seals;
6.6 Technical specifications for thrust bearing;
6.7 Technical specifications for gear box;
