What is a tracked changes standard?

A tracked changes version of a Standard indicates the changes made, during the standards revision process, between the active standard and its previous version. Additions, deletions, and other formatting and/or content revisions are clearly displayed as underlined and strikethrough texts, ensuring all changes made between the two documents are quickly and easily identified. This version of the standard includes both a copy of the new standard, along with a track changes version.

What is this standard about?

This is the tracked changes version of part one in a series of European standards on gas extinguishing fixed firefighting systems. This part deals with system design, installation and maintenance, while the other parts cover physical properties and system design for individual extinguishants.

Who is this standard for?

  • Gas extinguishing system designers, manufacturers and suppliers
  • Fire authorities
  • Fire safety managers and engineers
  • Landlords
  • Facilities managers and management companies
  • Servicing companies
  • Plants
  • Test laboratories

Why should you use this standard?

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. This standard meets the need to disseminate information on established systems and methods.

It specifies requirements and gives recommendations for the design, installation, testing, maintenance and safety of gas extinguishing 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 describes 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 by an appropriate independent authority of performance and safety characteristics.

This part of BS EN 15004 applies to the extinguishants listed in its Table 1 and is intended to be used in conjunction with the given parts of BS EN 15004 for fire extinguishing agents in Table 1. This document doesn’t apply to explosion suppression.

NOTE 1: This part of BS EN 15004 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.

NOTE 2: 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.

What’s changed in this update?

This tracked changes version highlights changes made since BS EN 15004-1:2008 was published. As well as editorial revisions and updates to normative references, the following technical changes have been made:

a)In Clause 3, the terms “lock-off device” and “regulated system” have been included

b)In Clause 4.2.2, “Environmental properties” has been included

c)In Clause 5 “Safety”, a table and equations for the maximum inert gas agent concentration at the NOAEL and LOAEL limits as a function of altitude have been included

d)Clause 6.3 “Distribution” has been revised

e)Clause 9.3 “Maintenance” has been revised

f)In Annex B “Determination of flame-extinguishing concentration of gaseous extinguishants by the cup burner method”, the procedures for flammable liquids and gases have been replaced by the procedures for inflammable liquids and gases and the reporting of results has been revised

g)Annex C “Fire extinguishment/area coverage fire test procedure for engineered and pre-engineered extinguishing units” has been revised

h)In Annex E “Door fan test for determining of minimum hold time”, the values for Interface Thickness (It) and Interface Position (Ip) have been included and the method of estimating F has been revised

i)In Annex G “Safe personnel exposure guidelines”, the extinguishant HFC 236fa and CF31 have been deleted

j)Annex H “Flow calculation implementation method and flow calculation verification and testing for approvals” has been revised
