Plastics - Smoke generation - Part 2: Determination of optical density by a single-chamber test (ISO 5659-2:2006)

ISO 5659-2:2006 specifies a method of measuring smoke production from the exposed surface of specimens of essentially flat materials, composites or assemblies not exceeding 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics and may also be used for the evaluation of other materials (e.g. rubbers, textile-coverings, painted surfaces, wood and other materials).
It is intended that the values of optical density determined by this test be taken as specific to the specimen or assembly material in the form and thickness tested, and are not to be considered inherent, fundamental, properties.
The test is intended primarily for use in research and development and in fire safety engineering of buildings, trains, ships, etc., and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that may be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions, nor is any correlation established with measurements derived from other test methods. This test procedure excludes the effect of irritants on the eye.

Kunststoffe - Rauchentwicklung - Teil 2: Bestimmung der optischen Dichte durch Einkammerprüfung (ISO 5659-2:2006)

1.1   Dieser Teil von ISO 5959 legt ein Verfahren zur Messung des Rauches fest, der auf der Oberfläche von Probekörpern entsteht, wenn im Wesentlichen flache Werkstoffe, Verbundstoffe oder vorgefertigte Teile mit einer Dicke von höchstens 25 mm horizontal angeordnet und in einer geschlossenen Prüfkammer mit oder ohne Anwendung einer Zündflamme einer Wärmebestrahlung mit einer bestimmten Intensität ausgesetzt werden. Dieses Prüfverfahren gilt für alle Kunststoffe und darf auch zur Bewertung anderer Werkstoffe (z. B. Gummi, textile Abdeckungen, Flächen mit Farbanstrichen, Holz und andere Baustoffe) angewendet werden.
1.2   Es wird davon ausgegangen, dass die Werte der nach dieser Prüfung bestimmten optischen Dichte für den Probekörper oder das vorgefertigte Teil nur in der untersuchten Form und Dicke spezifisch angesehen werden und nicht als werkstoffspezifische, grundlegende Eigenschaften.
1.3   Die Prüfung ist in erster Linie für die Anwendung in der Forschung und Entwicklung sowie bei der brandschutztechnischen Auslegung von Gebäuden, Zügen, Schiffen usw. und nicht als Bewertungsgrundlage für Bauvorschriften oder sonstige Anwendungen bestimmt. Weder ist eine Vorhersage für die Dichte des Rauches möglich, den Werkstoffe bei einer Beanspruchung durch Wärme und Flammen unter anderen Expositionsbedingungen erzeugen können, noch besteht eine Korrelation zu Messergebnissen, die nach anderen Verfahren ermittelt wurden. Dieses Prüfverfahren schließt den Einfluss von Reizstoffen auf die Augen aus.
ANMERKUNG      Dieses Prüfverfahren berücksichtigt die Verdunkelung des Sichtvermögens durch die Rauchentwicklung, die generell nicht in Beziehung zur Reizwirkung, wie im Teil 1 dieser Norm erklärt, steht.
1.4    Es wird darauf hingewiesen, dass die von einem Werkstoff ausgehende Rauchentwicklung von der Bestrahlungsstärke abhängt, die auf den Probekörper einwirkt. Bei Anwendung der Ergebnisse dieses Verfahrens sollte beachtet werden, dass die Ergebnisse bei einer Beanspruchung durch spez

Plastiques - Production de fumée - Partie 2: Détermination de la densité optique par un essai en enceinte unique (ISO 5659-2:2006)

L'ISO 5659-2:2006 spécifie une méthode pour le mesurage de la production de fumée provenant de la surface exposée des éprouvettes constituées par des matériaux essentiellement plats, des composites ou des assemblages dont l'épaisseur est inférieure à 25 mm, lorsqu'ils sont orientés horizontalement et soumis à des niveaux spécifiés d'éclairement énergétique thermique dans une enceinte fermée, avec ou sans utilisation de flamme pilote. La présente méthode d'essai est applicable à tous les plastiques et peut également être utilisée en vue de l'évaluation d'autres matériaux (par exemple caoutchoucs, revêtements textiles, surfaces peintes, bois et autres matériaux de construction).
Les valeurs de densité optique déterminées par le présent essai sont propres au matériau de l'éprouvette ou de l'assemblage soumis à essai, sous la forme et avec l'épaisseur sélectionnées pour l'essai. Ces valeurs ne doivent pas être considérées comme révélatrices de propriétés de base, inhérentes au produit.
L'essai est principalement destiné à être utilisé en recherche et développement et en ingénierie de sécurité incendie dans les bâtiments, les trains, les navires, etc., et non en tant que base d'appréciation pour des codes de construction ou pour d'autres fins. Aucun élément fondamental n'est fourni pour prévoir la densité de la fumée susceptible d'être produite par les matériaux exposés à la chaleur et à une flamme dans d'autres conditions (réelles) d'exposition, et aucune corrélation n'a été établie avec des mesurages obtenus au moyen d'autres méthodes d'essai. Le présent mode opératoire d'essai ne traite pas de l'effet des irritants sur les yeux.

ISO 5659-2:2006(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 5659-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 4, Burning
behaviour.
This second edition cancels and replaces the first edition (ISO 5659-2:1994), which has been technically
revised.
ISO 5659 consists of the following parts, under the general title Plastics — Smoke generation:
⎯ Part 1: Guidance on optical-density testing
⎯ Part 2: Determination of optical density by a single-chamber test
⎯ Part 3: Determination of optical density by a dynamic-flow method [Technical Report]

ISO 5659-2:2006(E)
Introduction
Fire is a complex phenomenon: its development and effects depend upon a number of interrelated factors.
The behaviour of materials and products depends upon the characteristics of the fire, the method of use of the
materials and the environment in which they are exposed (see also ISO/TR 3814 and ISO 13943).
A test such as is specified in this part of ISO 5659 deals only with a simple representation of a particular
aspect of the potential fire situation, typified by a radiant heat source, and it cannot alone provide any direct
guidance on behaviour or safety in fire. A test of this type may, however, be used for comparative purposes or
to ensure the existence of a certain quality of performance (in this case, smoke production) considered to
have a bearing on fire behaviour generally. It would be wrong to attach any other meaning to results from this
test.
The term “smoke” is defined in ISO 13943 as the visible part of fire effluent. It is one of the first response
characteristics to be manifested and should almost always be taken into account in any assessment of fire
hazard as it represents one of the greatest threats to occupants of a building, and other enclosed spaces such
as ships and trains, on fire.
The responsibility for the preparation of ISO 5659 was transferred during 1987 from ISO/TC 92 to ISO/TC 61
on the understanding that the scope and applicability of the standard for the testing of materials should not be
restricted to plastics but should also be relevant to other materials where possible, including building materials.

INTERNATIONAL STANDARD ISO 5659-2:2006(E)

Plastics — Smoke generation —
Part 2:
Determination of optical density by a single-chamber test
1 Scope
1.1 This part of ISO 5659 specifies a method of measuring smoke production from the exposed surface of
specimens of essentially flat materials, composites or assemblies not exceeding 25 mm in thickness when
placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet
with or without the application of a pilot flame. This method of test is applicable to all plastics and may also be
used for the evaluation of other materials (e.g. rubbers, textile-coverings, painted surfaces, wood and other
materials).
1.2 It is intended that the values of optical density determined by this test be taken as specific to the
specimen or assembly material in the form and thickness tested, and are not to be considered inherent,
fundamental, properties.
1.3 The test is intended primarily for use in research and development and in fire safety engineering of
buildings, trains, ships, etc., and not as a basis for ratings for building codes or other purposes. No basis is
provided for predicting the density of smoke that may be generated by the materials upon exposure to heat
and flame under other (actual) exposure conditions, nor is any correlation established with measurements
derived from other test methods. This test procedure excludes the effect of irritants on the eye.
NOTE This test procedure addresses the loss of visibility due to smoke density, which generally is not related to
irritancy potency, as explained in Part 1 of this International Standard.
1.4 It is emphasized that smoke production from a material varies according to the irradiance level to which
the specimen is exposed. In making use of the results of this method, it should be borne in mind that the
2 2
results are based on exposure to the specific irradiance levels of 25 kW/m and 50 kW/m .
