This document specifies the categories of flammable materials which are prohibited in all toys, and requirements concerning flammability of certain toys when they are subjected to a small source of ignition.

The test methods described in Clause 5 are used for the purposes of determining the flammability of toys under the particular test conditions specified. The test results thus obtained are not considered as providing an overall indication of the potential fire hazard of toys or materials when subjected to other sources of ignition.

This document includes general requirements relating to all toys and specific requirements and methods of test relating to the following toys, which are considered as being those presenting the greatest hazard:

— toys to be worn on the head: beards, moustaches, wigs, etc. made from hair, pile or material with similar features; masks; hoods, head-dresses, etc.; flowing elements of toys to be worn on the head, but excluding paper novelty hats of the type usually supplied in party crackers;

— toy disguise costumes and toys intended to be worn by a child in play;

— toys intended to be entered by a child;

soft-filled toys.

NOTE Additional requirements for flammability of electric toys are specified in EN 62115:2005.

This document specifies the minimum performance requirements and methods of test for helmets used for wildland firefighting.

This document covers the general design of wildland firefighting helmets, the minimum levels of performance for the materials employed and the methods of test used. This PPE is not intended to provide protection during fire entrapment.

This document does not cover PPE for structural firefighting (see ISO 11999-5), for use against chemical, biological, radiological and nuclear hazards, or for use where a reflective outer surface is required (see ISO 15538).

Activities in support of wildland firefighting, such as the cutting of trees and the use of a chainsaw can require additional protection to that provided in this document. Users are directed to those relevant standards for the requirements associated with such protection.

This document is to provide guidance for fire safety engineering that are applicable for enclosed fires. 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 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 Standard 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 Ct of components from fire environments. That 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.

This document specifies a test method for determining the fire resistance of smoke extraction ducts. It is applicable only to smoke extraction ducts that pass through another fire compartment from the fire compartment to be extracted in case of fire. It represents fire exposure of a fully developed fire.

This method of test is only applicable to ventilation ducts with the following classification according to EN 13501-3:

— fire from inside and outside i ↔ o;

— applicable to a pressure difference up to 500 Pa;

NOTE 1 Requires that the duct A test(s) has been preformed with an under-pressure of minimum 500 Pa.

— with integrity (E) and insulation (I) criteria equal to or higher than the intended classification for the smoke extraction duct.

NOTE 2 According to: EN 13501–4:2009/A1:2009 Multi-compartment smoke extraction duct can only be classified as EI.

For the purposes of the test described in this document, the duct is referred to as duct C.

This test method has been designed to cover both vertical and horizontal smoke extraction ducts. A vertical system need not be evaluated to this method provided that:

— both horizontal (ho) and vertical (ve) classification according to EN 13501-3 has been obtained for the ventilation duct, and

— it has been tested in a horizontal orientation to this method.

If the ventilation duct in practice is only used for vertical applications in smoke extraction systems, only vertical (ve) classification is bound to be used and tested in a vertical orientation to this method according to EN 13501-3.

This test method is suitable for ducts constructed from non-combustible materials (Euroclass A1 and A2).

NOTE 3 Using combustible material could lead to an incorrect calculation of the leakage based on the oxygen measurement. E.g. galvanisation could lead to some negative effects for the measurements.

It is applicable only to four sided ducts; one, two and three sided ducts are not covered.

This International Standard specifies the minimum performance requirements and methods of test for

Firehoods that cover the head and neck and are used for wildland firefighting. An optional requirement has been included to provide limited protection against particulate contaminants

This International Standard covers the general design of the PPE, the minimum levels of performance for the materials employed and the methods of test used. This PPE is not intended to provide protection during fire entrapment.

This document does not cover PPE for structural firefighting (see ISO 11999-9). This standard only applies in situations when compatible protective clothing, helmet, and when necessary respiratory protection devices are also worn.
