This document specifies the apparatus and procedure for measuring reaction to fire behaviour under reduced oxygen atmospheres. Continuous measurements are made to calculate heat release rates, smoke and specific gas production rates, and mass loss rates. Ignition time measurements are also made and ignition behaviour is obtained. Pyrolysis parameters of specimens exposed to controlled levels of irradiance and controlled levels of oxygen supply can be determined as well.

Different reduced oxygen atmospheres in the test environment are achieved by controlling the oxygen volume concentration of input gas fed into the chamber (vitiation) or by controlling the total volume of atmosphere fed into the chamber (ventilation). Ranges of oxygen volume concentration below 20,95 % of oxygen can be studied. The apparatus is not intended to control enriched oxygen conditions above atmospheric 20,95 % oxygen concentration.

The measurement system prescribed in this document is based on the cone calorimeter apparatus described in ISO 5660-1. Therefore, this document is intended to be used in conjunction with ISO 5660-1.

1.1 This document specifies the minimum requirements for safety and performance of some optional specific permanently installed equipment on firefighting and rescue service vehicles, operated by trained persons, as designated in EN 1846 1:2011 and specified in EN 1846 2:2024. NOTE 1 Categories and mass classes of these vehicles are given in EN 1846 1:2011. NOTE 2 Vehicle means ground vehicles which can also drive on rails and amphibious vehicles. The permanently installed equipment covered by this document is given below: — water installation; — additive installation; — monitor; — equipment gantries; — demountable systems. This document covers also the use of wireless control systems. NOTE This document is assumed to be read in conjunction with any national regulations in force for vehicles using the public roads and with any EU Directives and associated EFTA regulations in force relevant to vehicles and their equipment. For the purposes of this document, the normal ambient temperature range is - 15 °C to + 40 °C. For equipment to be used at temperature outside this temperature range, the particular temperature range is specified by the user. A risk assessment determines any need for additional precautions. 1.2 This document does not deal with the following types of equipment: — all control systems outside of the cabin related to hook arm system; — provisions for non-firefighting removable equipment driven by PTO. 1.3 This document deals with the technical requirements to minimize the hazards listed in Annex A which can arise during operational use, routine checking and maintenance of firefighting and rescue service vehicles. It does not cover the hazards generated by: — non-permanently installed equipment i.e. portable equipment carried on the vehicle; — use in potentially explosive atmospheres; — commissioning and decommissioning; — noise (as permanently installed equipment cannot be operated separately from the vehicle, this hazard is covered in EN 1846 2:2024); — electromagnetic compatibility; — cyber security; — cyber safety. Additional measures not dealt with in this document can be necessary for specific use (e.g. fire in natural environment, flooding, etc.). 1.4 This document is not applicable to the equipment which is manufactured before its date of publication by CEN.

EXAP standard specific to the materials typically used within composite fire and smoke control doors.

This document covers the following aspects of fire testing of plastics materials and products: -

— Selection of appropriate tests that reflect realistic end-use conditions

— Grouping of the reaction-to-fire characteristics that any given test or tests can measure

— Assessment of tests as to their relevance in areas such as material characterisation, quality control, preselection,

end-product testing, environmental profiling and DfE (Design for the Environment)

— Definition of potential problems that may arise when plastics are tested in standard fire tests

This document does not include specification for development or design of new fire-tests for plastics.

However, the flexibility of approach that is indicated with respect to the mounting and fixing of test

specimens is valuable when fire testing laboratories and certification bodies are considering how to evaluate

ranges of plastics that are used in different ways.

This European Standard specifies requirements and gives recommendations for the design, installation and maintenance of fixed fire sprinkler systems in buildings and industrial plants, and particular requirements for sprinkler systems that are integral to measures for the protection of life.

This European Standard covers only the types of sprinkler specified in EN 12259 1 (see Annex L).

The requirements and recommendations of this European Standard are also applicable to any addition, extension, repair or other modification to a sprinkler system. They are not applicable to water spray or deluge systems.

It covers the classification of hazards, provision of water supplies, components to be used, installation and testing of the system, maintenance, and the extension of existing systems, and identifies construction details of buildings which are the minimum necessary for satisfactory performance of sprinkler systems complying with this European Standard.

This European Standard does not cover water supplies to systems other than sprinklers. Its requirements can be used as guidance for other fixed firefighting extinguishing systems, provided that any specific requirements for other firefighting extinguishing supplies are taken into account.

This European Standard is intended for use by those concerned with purchasing, designing, installing, testing, inspecting, approving, operating and maintaining automatic sprinkler systems, in order that such equipment will function as intended throughout its life.

This European Standard is intended only for fixed fire sprinkler systems in buildings and other premises on land. Although the general principles might well apply to other uses (e.g. maritime use). For these other uses additional considerations should be taken into account.

The requirements are not valid for automatic sprinkler systems on ships, in aircraft, on vehicles and mobile fire appliances or for below ground systems in the mining industry.

Sprinkler system design deviations might be allowed when such deviations have been shown to provide a level of protection at least equivalent to this European Standard, for example by means of full-scale fire testing where appropriate, and where the design criteria have been fully documented.
