ISO 14520-1:2006 has the following foreword:

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 14520-1 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 8, Gaseous media and firefighting systems using gas.

This second edition cancels and replaces the first edition (ISO 14620-1:2000), which has been technically revised.

Annex С has been extensively revised to include polymeric sheet fuel array fire tests [polymethyl methacrylate (PMMA)], [polypropylene (PP)] and [acrylonitrile-butadiene-styrene (ABS)]. These tests are designed to more closely represent plastic fuel hazards such as may be encountered in information technology, telecommunications and process control facilities.

Annex E has been re-structured to accommodate lighter-than-air gases and to provide means for dealing with non-standard (as opposed to geometrically regular) hazard enclosures.

Also incorporated in this revision of ISO 14520-1 are safe personnel exposure guidelines, Annex G, recognizing physiologically based pharmacokinetic (PBPK) modelling and hypoxic guidelines to define safe human exposure limits.

ISO 14520 consists of the following parts, under the general title Gaseous media fire extinguishing systems - Physical properties and system design:

- Part 1: General requirements

- Part 2: CF3I extinguishant

- Part 5: FK-5-1-12 extinguishant

- Part 6: HCFC Blend A extinguishant

- Part 8: HFC 125 extinguishant

- Part 9: HFC 227ea extinguishant

- Part 10: HFC 23 extinguishant

- Part 11: HFC 236fa extinguishant

- Part 12 IG-01 extinguishant

- Part 13: IG-100 extinguishant

- Part 14: IG-55 extinguishant

- Part 15: IG-541 extinguishant

Parts 3, 4 and 7, which dealt with FC-2-1-8, FC-3-1-10 and HCFC 124 extinguishants, respectively, have been withdrawn, as these types are no longer manufactured.

 

Introduction

Fire fighting systems covered in this document are designed to provide a supply of gaseous extinguishing medium for the extinction of fire.

Several different methods of supplying extinguishant to, and applying it at, the required point of discharge for fire extinction have been developed in recent years, and there is a need for dissemination of information on established systems and methods. This document has been prepared to meet this need.

In particular, new requirements to eliminate the need to release extinguishants during testing and commissioning procedures are included. These are linked to the inclusion of enclosure integrity testing.

The requirements of this document are made in the light of the best technical data known to the working group at the time of writing but, since a wide field is covered, it has been impracticable to consider every possible factor or circumstance that might affect implementation of the recommendations.

It has been assumed in the preparation of this document that the execution of its provisions is entrusted to people appropriately qualified and experienced in the specification, design, installation, testing, approval, inspection, operation and maintenance of systems and equipment, for whose guidance it has been prepared, and who can be expected to exercise a duty of care to avoid unnecessary release of extinguishant.

Attention is drawn to the Montreal Protocol on substances that deplete the ozone layer.

It is important that the fire protection of a building or plant be considered as a whole. Gaseous extinguishant systems form only a part, though an important part, of the available facilities, but it should not be assumed that their adoption necessarily removes the need to consider supplementary measures, such as the provision of portable fire extinguishers or other mobile appliances for first aid or emergency use, or to deal with special hazards.

Gaseous extinguishants have for many years been a recognized effective medium for the extinction of inflammable liquid fires and fires in the presence of electrical and ordinary Class A hazards, but it should not be forgotten, in the planning of comprehensive schemes, that there may be hazards for which these media are not suitable, or that in certain circumstances or situations there may be dangers in their use requiring special precautions.

Advice on these matters can be obtained from the appropriate manufacturer of the extinguishant or the extinguishing system. Information may also be sought from the appropriate fire authority, the health and safety authorities and insurers. In addition, reference should be made as necessary to other national standards and statutory regulations of the particular country.

It is essential that fire fighting equipment be carefully maintained to ensure instant readiness when required. Routine maintenance is liable to be overlooked or given insufficient attention by the owner of the system. It is, however, neglected at peril to the lives of occupants of the premises and at the risk of crippling financial loss. The importance of maintenance cannot be too highly emphasized. Installation and maintenance should only be done by qualified personnel.

Inspection preferably by a third party should include an evaluation that the extinguishing system continues to provide adequate protection for the risk (protected zones as well as state of the art can change over time).

The test protocol contained in Annex С of this document was developed by a special working group of ISO/ТС 21/SC 8. Annex С deals with the tests for determination of the extinguishing concentrations and system performance and they are designed in such a way to allow individual installers to use his/her system and carry out all of the extinguishing tests. The need for the tests presented in Annex С was established by the fact that the previously used Class A fire test involved wood crib, heptane pan and heptane can test fires in an enclosure of minimum 100 m3, and did not necessarily indicate extinguishing concentrations suitable for the protection of plastic fuel hazards such as may be encountered in information technology, telecommunications and process control facilities.

As a consequence of the above, the current Annex С of this document has been revised as described in the Foreword.

 

1 Scope

This document specifies requirements and gives recommendations for the design, installation, testing, maintenance and safety of gaseous fire fighting systems in buildings, plants or other structures, and the characteristics of the various extinguishants and types of fire for which they are a suitable extinguishing medium.

It covers total flooding systems primarily related to buildings, plants and other specific applications, utilizing electrically non-conducting gaseous fire extinguishants that do not leave a residue after discharge and for which there are sufficient data currently available to enable validation of performance and safety characteristics by an appropriate independent authority. This document is not applicable to explosion suppression.

This document is not intended to indicate approval of the extinguishants listed therein by the appropriate authorities, as other extinguishants may be equally acceptable. CO2 is not included as it is covered by other International Standards.

This document is applicable to the extinguishants listed in Table 1. It is intended to be used in conjunction with the separate parts of EN 15004 for specific extinguishants, as cited in Table 1.
