This document describes the conditioning procedures for test specimens which will be tested according to the European standards for reaction to fire. The rules for the selection of substrates for construction products when carrying out reaction to fire tests are also detailed in this document. This document does not contain requirements for - the pre-drying of test specimens for the non-combustibility test according EN ISO 1182; - methods of cleaning (e.g. washing) and other methods for the assessment of durability aspects, which are dealt with in the relevant product standards.

 

This document specifies the requirements governing the application of a set of explicit algebraic formulae for the calculation of specific characteristics of flashover related phenomena.

 

This document is only one of many tools available for use in fire safety engineering. It is intended to be used in conjunction with models for analysis of the initiation and development of fire, fire spread, smoke formation and movement, chemical species generation, transport and decay, and people movement, as well as fire detection and suppression. This document is to be used only within this context. This document is intended to address the consequences of human exposure to the heat, obscuration induced by smoke and proposed a simplified mass-loss-based toxicity model. The time-dependent thermal environment of a fire and aerosol concentrations are determined by the rate of fire growth and the ventilation pattern. Once these are determined, the methodology presented in this document can be used for the estimation of the time at which individuals can no longer accomplish their own escape or reach a place of safe refuge. This guidance can also be applied to estimation of the time limit for rescuing people who are immobile due to injury, medical condition, etc. This document establishes procedures to evaluate the life threat components of fire hazard analysis in terms of the status of exposed human subjects at discrete time intervals. It makes possible the estimation of a tenability endpoint, at which time it is estimated that occupants are no longer able to take effective action to accomplish their own escape. It enables estimation of a tenability endpoint for each of the fire effluent components, with the most important endpoint being the earliest to occur. Although occupants’ inability to accomplish their own escape is consistent with the definition of incapacitation (see ISO 13943), this term is not used in this document due to its potentially broad interpretation to include many effects, including collapse and unconsciousness, that are not addressed. This document focuses specifically on taking effective action to accomplish escape as may be influenced by both physiological and behavioural responses resulting from exposure to fire’s life threat components. The life threat components addressed in this standard include heat and visual obscuration due to smoke together with a simplified mass-loss-based model for toxicity assessment of combustibles.

 

This document provides guidance for fire safety engineering that is applicable for fires in enclosed spaces. It is intended to be used in conjunction with models for analysis of the initiation and development of fire, fire spread, impact of heat, radiation, and limited visibility, smoke formation and movement, chemical species generation, transport and decay, and people movement, as well as fire detection and suppression, given in the normative references in clause 2. This document is intended to be used only within this context. This document establishes procedures to evaluate the effects of life-threatening components from fire environments in terms of the probability of compromised tenability of a targeted human population at accumulated time intervals. It makes possible the estimation of the time at which people can experience compromised tenability due to smoke, heat and toxic fire effluent. The most critical hazard is that which causes compromised tenability at the earliest time. The time-dependent production of smoke and toxic fire effluent and the thermal environment of a fire are determined by the rate of fire growth, the yields of the various fire gases produced from the involved fuels, the decay characteristics of those fire gases and the ventilation pattern (see A.1). Once these are determined, the methodology presented in this International Document can be used for the estimation of the time at which individuals can be expected to experience compromised tenability. This document establishes procedures to evaluate the life-threatening components from fire environments in terms of the probability of a targeted human population at accumulated time intervals. It makes possible the estimation of the time at which people in enclosed spaces can experience compromised tenability (see A.2). It enables an estimation of compromised tenability for each predicted Cxt (Concentration x time) of components from fire environments. In addition, the time to untenability due to the impact of heat and of smoke (visibility) needs to be considered. The impact leading to attain compromised tenability at FED = 1 earliest is considered the most critical. The non-lethal threshold-based derivation of the occurrence of compromised tenability also protects from post-exposure mortality. Details for assessing the impact of heat and smoke will be given in ISO 13571-5. This method is intended to assess the escape capability of people in an environment, where generally adult and not handicapped people are expected, as for example in industrial and working surroundings. In addition, susceptible people are covered in this document based on the already included adjustment factors explained below. For the escape capability of hyper-susceptible people, no meaningful additional assessment factors can be defined, but this document can be applied in a meaningful way for places where it can be assumed that hyper-susceptible or helpless people will always get assistance for escape, like in child care units or hospitals. This document covers all fire stages including smouldering fires or other scenarios where high emissions of CO2 can be expected, as CO2 is considered as a toxicant per se for higher concentrations. Recent fire tests have shown that in some fire scenarios CO2 can be found in relevant concentrations [19-21] and has to be considered as a toxicant per se. For applying this document the basic information given in ISO 13344, and in ISO 19706 also is relevant.[58,59]

 

This document defines key terminology, establishes circular economy principles at the levels of construction works as well as construction products of all kinds, and provides a guidance framework for the implementation and assessment of circularity in the built environment.

This document describes test methods and methods for classification of wood and wood-based products for which a stage in the production process results in an improvement of the reaction-to-fire classification in accordance with EN 13501-1 for use in interior and exterior situations (use classes 1, 2, and 3 as defined in EN 335:2013). NOTE The classes of this document are not performance classes and do not give guidance for how long the reaction to fire classification of wood or wood-based product will last. This document applies to - wood and wood-based products (specific wood species, wood treated with preservatives and modified wood, for example thermally and chemically modified wood) that have been treated with fire-retardant chemical(s) applied either by a penetrating process or by a superficial process, such as with a film forming fire-retardant coating. - wood-based products that incorporate fire retardant chemical(s) as part of the production process. This document also covers fire-retardant wood and wood-based products that have a non-fire-retardant coating. Mechanical properties, aesthetic properties, dimensional stability properties, service life and biological durability of fire-retardant wood and wood-based products are not covered by this document.

This document gives guidance on the general procedures to be followed in the sampling and preparation for analysis of wood preservatives and preservative-treated timber. This document is applicable to the provision of appropriate samples for analysis which can be used to check the content of active and other ingredients in preservative formulations, and the content of active and other ingredients of wood preservatives in treated timber, either before, during or after the service life of the timber. NOTE 1 Methods of sampling creosote and creosote-treated timber are described in EN 1014-1, EN 1014-2 and EN 12490. These are used in preference to the recommendations in this document. NOTE 2 No attempt has been made in this document to lay down detailed procedures to be adopted for control purposes at manufacturing plants where large volumes of preservatives are sampled. Nor does it attempt to establish procedures for checking the compliance of batches of treated timber with specifications demanding a defined level of treatment (see 6.2).
