This document assesses the utility of physical fire models that have been standardized, are commonly used, and/or are cited in national or international standards, for generating fire effluent toxicity data of known accuracy. This is achieved by using the criteria established in ISO 16312-1 and the guidelines established in ISO 19706. The aspects of the models that are considered are: the intended application of the model, the combustion principles it manifests, the fire stage(s) that the model attempts to replicate, the types of data generated, the nature and appropriateness of the combustion conditions to which test specimens are exposed, and the degree of validity established for the model.

This International Standard presents a range of sampling and chemical analytical methods suitable for
the analysis of individual chemical species in fire atmospheres. The procedures relate to the analysis of
samples extracted from an apparatus or effluent flow from a fire test rig or physical fire test model and
are not concerned with the specific nature of the fire test.
This International Standard doesn’t cover aerosols (detailed in Reference [3]) and FTIR technique
(detailed in Reference [4]). The gases of environmental interest, such as PAH, dioxins, furans, endocrinal
disturbers, will be developed in a future document by ISO TC92/SC3.

This International Standard provides a means for estimating the lethal toxic potency of the fire effluent
produced from a material while exposed to the specific combustion conditions of a physical fire model.
The lethal toxic potency values are specifically related to the fire model selected, the exposure scenario
and the material evaluated.
Lethal toxic potency values associated with 30-min exposures of rats are predicted using calculations
which employ combustion atmosphere analytical data for carbon monoxide (CO), carbon dioxide (CO2),
oxygen (O2) (vitiation) and, if present, hydrogen cyanide (HCN), hydrogen chloride (HCl), hydrogen
bromide (HBr), hydrogen fluoride (HF), sulfur dioxide (SO2), nitrogen dioxide (NO2), acrolein and
formaldehyde. The chemical composition of the test specimen may suggest additional combustion
products to be quantified and included. If the fire effluent toxic potency cannot be attributed to the
toxicants analysed (Annex A), this is an indication that other toxicants or factors must be considered.
This International Standard is applicable to the estimation of the lethal toxic potency of fire effluent
atmospheres produced from materials, products or assemblies under controlled laboratory conditions
and should not be used in isolation to describe or appraise the toxic hazard or risk of materials, products
or assemblies under actual fire conditions. However, results of this test may be used as elements of a
fire hazard assessment that takes into account all of the factors which are pertinent to an assessment of
the fire hazard of a particular end use; see ISO 19706.
The intended use of fire safety-engineering calculations is for life-safety prediction for people and is
most frequently for time intervals somewhat shorter than 30 min. This extrapolation across species
and exposure intervals is outside the scope of this International Standard.
This International Standard does not purport to address all of the safety problems associated with its
use. It is the responsibility of the user of this International Standard to establish appropriate safety and
health practices.

ISO 15928-4:2017 sets out a method for describing the fire safety performance of houses. It covers user needs, provides performance descriptions, and outlines evaluation processes. It includes the description of relevant parameters for early warning, fire suppression, fire containment, means of escape, control of structural behaviour, and emission and spread of fire effluent. ISO 15928-4:2017 is intended for use in the evaluation of the design and construction of houses, in the international trading of houses or their sub-systems, and in developing risk-management tools for the protection of houses. It does not specify a level of performance and it is not intended to provide a design method and/or criteria. ISO 15928-4:2017 does not cover the performance of houses exposed to wild fire. NOTE 1 Structural safety and other performance attributes of a house are covered in other parts of the ISO 15928 series. NOTE 2 The emission of smoke and hot gases from contents in the house when ignited can impact the fire safety performance of a house, but the type or nature of such contents brought into the house is not the subject of the evaluation process. NOTE 3 The term "wild fire" is used to mean the concept of wild land fire, bush fire and unplanned burning in vegetative fuels, etc.

ISO 16852:2016 specifies the requirements for flame arresters that prevent flame transmission when explosive gas-air or vapour-air mixtures are present. It establishes uniform principles for the classification, basic construction and information for use, including the marking of flame arresters, and specifies test methods to verify the safety requirements and determine safe limits of use.
This International Standard is valid for pressures ranging from 80 kPa to 160 kPa and temperatures ranging from −20 °C to + 150 °C.
NOTE 1 For flame arresters with operational conditions inside the scope, but outside atmospheric conditions, see 7.4.
NOTE 2 In designing and testing flame arresters for operation under conditions other than those specified above, this International Standard can be used as a guide. However, additional testing related specifically to the intended conditions of use is advisable. This is particularly important when high temperatures and pressures are applied. The test mixtures might need to be modified in these cases.
NOTE 3 An additional standard IMO MSC/Circ. 677 for maritime application from IMO (International Maritime Organization) exists.
ISO 16852:2016 is not applicable to the following:
- external safety-related measurement and control equipment that might be required to keep the operational conditions within the established safe limits;
NOTE 4 Integrated measurement and control equipment, such as integrated temperature and flame sensors as well as parts which, for example, intentionally melt (retaining pin), burn away (weather hoods) or bend (bimetallic strips), is within the scope of this International Standard.
- flame arresters used for explosive mixtures of vapours and gases, which tend to self-decompose (e.g. acetylene) or which are chemically unstable;
- flame arresters used for carbon disulphide, due to its special properties;
- flame arresters whose intended use is for mixtures other than gas-air or vapour-air mixtures (e.g. higher oxygen-nitrogen ratio, chlorine as oxidant, etc.);
- flame arrester test procedures for internal-combustion compression ignition engines;
- fast acting valves, extinguishing systems and other explosion isolating systems.

This European Standard provides guidance and rules to notified bodies (for fire dampers) to allow them to produce/validate an extended field of application report for fire dampers. This standard identifies the parameters that affect the fire resistance of dampers. It also identifies the factors that need to be considered when deciding whether, or by how much, the parameter can be extended when contemplating the fire resistance performance of an untested, or untestable variation in the construction.
This European Standard explains the principles behind how a conclusion on the influence of specific parameters/constructional details relating to the relevant criteria (E,I,S) can be achieved.
This European Standard does not cover dampers used for smoke control.
This European Standard only applies to extended fields of application based on tests successfully undertaken to EN 1366-2. Only test reports that have a total test time where the criteria are fulfilled that is in excess of the required classification period by a margin of either 10 % or 12 min, whichever is the least, are to be considered. Each classification (E,I,S) is to be considered individually - consequently E (134 min achieved) may be extended, but EI (61 min achieved) may not be extended for a classification of EI60.
Additionally, leakage determined during such tests is to be at least 10 % below the leakage limits for E, or for E-S, dependent on classification achieved, given in EN 13501-3 before the EXAP rules can be applied. The 10 % below the leakage limits is to be fulfilled for the extended period in addition to the classification period.
By application of this European Standard, it should be possible to identify what specifications should be tested to maximize the field of application. Some information on test programmes is given for guidance purposes.

This European Standard specifies a test method for determining the ability of a vertical protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance (loadbearing capacity R) of loadbearing vertical structural building members fabricated from steel, concrete, steel/concrete composites or timber. The method described is applicable to any type of vertical protective membrane, which can be associated with a separate bracing membrane.
The vertical protective membrane can be either separated from or attached to the structural building member and is self-supporting. This test method is applicable to vertical protective membranes where there is a gap and a cavity between the vertical protective membrane and the structural building member, otherwise alternative test methods prEN 13381-3, EN 13381-4, EN 13381-6 or prEN 13381-7 should be used as appropriate.
This test method and assessment is not applicable to the following:
a) all situations where the cavity is to be used as a service or ventilation shaft;
b) all situations where the vertical protective membrane acts as a bracing membrane.
This European Standard contains the fire test which specifies the tests which shall be carried out whereby the vertical protective membrane together with the structural member to be protected is exposed to the specified fire. The fire exposure, to the standard temperature/time curve given in EN 1363-1, is applied to the side which would be exposed in practice.
The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given in EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2.
This European Standard also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected vertical structural member.
The results of the fire test and the assessment can be applied, with certain defined provisions, to vertical structural building members which can be beams, columns or a combination of both and / or which could form part of a separating element or partition.
The limits of applicability of the results of the assessment arising from the fire test are defined, together with permitted direct application of the results to different structures, membranes and fittings.
In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in Annex B.
Tests should be carried out without additional combustible materials in the cavity.

This European Standard defines requirements for running capability under fire conditions which are applicable to passenger carrying railway rolling stock. In particular, technical measures are specified, compliance with which will contribute to conformity with the Directive and the relevant Technical Specifications for Interoperability (TSI). The standard specifies the fire conditions: - for which it is not necessary to define running capability requirements as there is no significant potential for serious injury or threat to life; - for which it is reasonable to expect trains to continue to run in a controlled manner; - for which it is not reasonably practicable to define requirements which give complete assurance of running in a controlled manner, due to the exceptional nature of the fire incident. The TSI SRT defines running capability requirements in respect of fires within technical areas/equipment only. However for general guidance the scope of this standard is extended to include fires from non-technical causes within passenger/staff areas which may impact train system functions adjacent to and/or passing through the affected area. This extension of applicability significantly increases the number of system functions which are potentially at risk and therefore requires that the "reasonably practicable" principles be extended to this new condition. The standard does not consider situations where a primary non-fire incident is likely to immobilise the train by definition; for example major mechanical defect leading to derailment, even when fire then occurs.

ISO 27368:2008 details analytical methods suitable for analysing the two primary toxic combustion gases, carbon monoxide (CO) and hydrogen cyanide (HCN), in blood samples collected from fire casualties. In blood, CO is measured as carboxyhaemoglobin (COHb) and HCN as cyanide ion (CN-). Although numerous methods are reported in the literature for performing blood COHb and CN- analyses, the analytical methods included herein are based upon their suitability for performing the analysis on ante-mortem and post-mortem blood samples from fire casualties. The analytical principle, analysis time, repeatability, reproducibility, robustness, effectiveness and instruments used are considered for those methods. Some of the methods described in ISO 27368:2008 might not be suitable for analysing putrid or clotted blood. Burned (solid) blood can be analysed after homogenization.

This Technical Report gives recommendations and guidance on functional and calculation methods for smoke and heat exhaust ventilation systems for steady-state design fires. It is intended for a variety of building types and applications, including single-storey buildings, mezzanine floors, warehouses with palletized or racked storage, shopping malls, atria and complex buildings, car parks, places of entertainment and public assembly and un-compartmented space within multi-storey buildings.
This Technical Report does not include any functional recommendations for design parameters where the primary purpose of the SHEVS is to assist fire-fighting.
NOTE   Such functional recommendations need to be agreed with the fire service responsible for the building in question. The calculation procedures set out in the annexes of this Technical Report can be used to design the SHEVS to meet whatever recommendations have been agreed.
This Technical Report does not cover the following:
-   smoke clearance, where smoke is exhausted from a building after the fire has been suppressed;
-   cross-ventilation, where wind-induced or fan-induced air currents sweep smoke through and out of the building, usually as part of fire-fighting operational procedures;
-   ventilation of stairwells, which usually represents a special application of smoke clearance and which does not necessarily protect the continued use of the stairwell;
-   fully-involved fires.

This document provides guidance and rules to notified bodies (for fire dampers) allowing them to produce/validate an extended field of application report for fire dampers. This document identifies the parameters that affect the fire resistance of dampers. It also identifies the factors that need to be considered when deciding whether, or by how much, the parameter can be extended when contemplating the fire resistance performance of an untested, or untestable variation in the construction.
This document explains the principles behind how a conclusion on the influence of specific parameters/constructional details relating to the relevant criteria (E, I, S) can be achieved.
This document does not cover dampers used for smoke control.
It is the intention that the application of this document makes it possible to identify which specifications to test to maximize the field of application. Some information on test programmes is given for guidance purposes.
