This document establishes the general principles for determining the fire resistance of various elements of construction when subjected to standard fire exposure conditions. Alternative and additional procedures to meet special requirements are given in EN 1363-2. The principle that has been embodied within all European standards relating to fire resistance testing is that where aspects and procedures of testing are common to all specific test methods e.g. the temperature/time curve, then they are specified in this test method. Where a general principle is common to many specific test methods but the details vary according to the element being tested (e.g. the measurement of unexposed face temperature), then the principle is given in this document, but the details are given in the specific test method. Where certain aspects of testing are unique to a particular specific test method (e.g. the air leakage test for fire dampers), then no details are included in this document. The test results obtained might be directly applicable to other similar elements, or variations of the element tested. The extent to which this application is permitted depends upon the field of direct application of the test result. This is restricted by the provision of rules which limit the variation from the tested specimen without further evaluation. The rules for determining the permitted variations are given in each specific test method. Variations outside those permitted by direct application are covered under extended application of test results. This results from an in-depth review of the design and performance of a particular product in test(s) by a recognized authority. Further consideration on direct and extended application is given in Annex A. The duration for which the tested element, as modified by its direct or extended field of application, satisfies specific criteria will permit subsequent classification. All values given in this document are nominal unless otherwise specified.

This document specifies a method for determining the fire resistance of air transfer grilles (ATG). It is applicable to air transfer grilles intended for installation in building components (typically walls, floors or ceilings). The orientation of the installation of the air transfer grille can be vertical or horizontal. The closing mechanism of the air transfer grille can come from expansion of material and/or from any mechanical or electrical closing device. This test method is valid for fire resistant or fire resistant and smoke control air transfer grilles. An additional test configuration is valid for fire resistant or fire resistant and smoke control air transfer grilles in applications where flame impingement is a risk during open state from start of fire (Annex A). This test method evaluates the behaviour of the air transfer grille when exposed to the standard fire curve described in EN 1363 1 and the standard pressure described in EN 1363 1. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes under fire conditions. Such phenomena are only noted in describing the general behaviour of test specimens during the test. The rate of leakage of smoke at ambient temperature or at 200 °C as an optional requirement for ATG with declared smoke control will be confirmed in accordance with EN 1634 3. This test method is not valid for determining the fire resistance of air transfer grilles that are used in ducts because ATG are considered as separating elements. The test method for ATG, used in ducts is described in the corresponding duct standards. This test method is not valid for determining the fire resistance of a fire damper or a fire barrier connected to a duct on either or both sides because an ATG is tested as a fire-separating element on its own. Fire dampers are tested according to EN 1366 2. Non-mechanical fire barriers are tested according to EN 1366 12. This test method is not valid for determining the fire resistance of air transfer grilles in fire doors, shutters and openable windows as specified in EN 1634 1 and EN 1364 2, because the deformation of fire doors, shutters and openable windows in fire conditions differs from the deformation of flexible/rigid walls. Moreover, the location of thermocouples in the door standard is too specific to be handled in this document. All values given in this document are nominal unless otherwise specified.

This document specifies safety requirements, performance requirements, test methods, instructions for use and maintenance, and marking requirements for portable monitor assemblies. NOTE 1 Additional requirements for water nozzles and foam devices can be found in EN 15767-2 and EN 15767-3 respectively. NOTE 2 Fitting systems are dealt with in national standards or requirements, respectively. This document is applicable to portable monitor assemblies that can be both permanently installed (e.g. on a flange, a vehicle, a fire boat, etc.) and can also be used as portable monitor assemblies. This document can be read in conjunction with either part 2 or 3. This document is not applicable to monitors permanently installed on firefighting and rescue service vehicles, for which requirements are given in EN 1846-3 [2]. This document is not applicable to portable monitor assemblies which are manufactured before its date of publication.

In addition to the requirements given in EN 15767-1, this document is applicable to manual water nozzles, including water with fire extinguishing additives. It specifies requirements for safety, performance, classification and designation, as well as test methods, instructions for use and maintenance and marking. This document is not applicable to water nozzles that are manufactured before its date of publication.

In addition to the requirements given in EN 15767-1, this document applies to devices designed for aspirating air and projecting low expansion foam and, in some cases, inducting foam concentrate. It specifies requirements for safety, performance, classification and designation, as well as test methods, instructions for use and maintenance and marking. This document is not applicable to water nozzles that are manufactured before its date of publication.

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.
