Cable management systems - Test method for content of halogens

This European Standard specifies a method for the determination of the content of halogens in products made of polymeric or composite materials by combustion, subsequent analysis of the combustion product by Ion Chromatography and how this information is declared.
This European Standard is for environmental purposes only.
Compliance with this standard does not guarantee the absence of toxicity, corrosivity or opacity of produced smoke, or other reaction to fire characteristics. If any of these characteristics are to be evaluated, the suitable standards need to be used
This method is suitable for samples containing more than 0,025 g/kg of a halogen.
Halides insoluble in aqueous solution present in the original sample or produced during the combustion step are not determined by these methods.

Diese Europäische Norm ist ausschließlich für umweltbezogene Zwecke vorgesehen.
Die Übereinstimmung mit dieser Norm garantiert nicht die Abwesenheit von Toxizität, Korrosivität oder Trübung von erzeugtem Rauch oder andere Eigenschaften des Brandverhaltens. Ist eine dieser Eigen¬schaften zu bewerten, müssen die geeigneten Normen angewendet werden.
Dieses Verfahren ist geeignet für Proben mit mehr als 0,025 g/kg Halogengehalt.
In der ursprünglichen Probe vorhandene oder beim Verbrennungsschritt erzeugte, in wässriger Lösung unlösliche Halogenide werden mit diesen Verfahren nicht bestimmt.

Systèmes de gestion de câblage - Méthode d'essai relative à la teneur en halogènes

La présente Norme européenne spécifie une méthode de détermination de la teneur en halogènes dans les produits ou les constituants de produits en matériau(x) polymère(s), pour les systèmes de câblage (CMS, Cable Management Systems). Ladite détermination est réalisée par combustion et analyse ultérieure du produit de combustion par chromatographie ionique. La présente norme spécifie la façon dont les produits pour CMS (systèmes de câblage) peuvent être déclarés sans halogènes.
La présente Norme européenne concerne uniquement les performances environnementales.
La conformité à la présente norme ne garantit pas l'absence de toxicité, de corrosivité ou d'opacité de la fumée générée, ou d'autres caractéristiques de réaction au feu. Lorsque l'une quelconque de ces caractéristiques doit être évaluée, les normes appropriées peuvent être utilisées.
La limite de détection de cette méthode d'essai est de 0,025 g d'halogène par kg (0,0025 %).
Cette méthode ne permet pas de déterminer les halogénures insolubles en solution aqueuse présents dans l’échantillon d’origine ou produits au cours de la phase de combustion.

Sistemi za urejanje okablenja - Metoda za preskušanje vsebnosti halogenov

Ta evropski standard določa metodo za določevanje vsebnosti halogenov v izdelkih, izdelanih s sežigom polimernih ali kompozitnih materialov, naknadno analizo produkta izgorevanja z ionsko kromatografijo in način deklariranja teh informacij.
Ta evropski standard se uporablja samo za okoljske namene.
Skladnost s tem standardom ne zagotavlja odsotnosti strupenosti, korozivnosti ali motnosti proizvedenega dima ali drugega odziva na lastnosti ognja. Če je treba ovrednotiti katero od zgoraj navedenih lastnosti, morajo biti uporabljeni ustrezni standardi.
Ta metoda je primerna za vzorce, ki vsebujejo več kot 0,025 g/kg halogena.
Te metode ne določajo halidov, ki niso topni v vodni raztopini in so prisotni v prvotnem vzorcu ali nastanejo v fazi izgorevanja.

1 Scope
This European Standard specifies a method for the determination of the content of halogens in Cable
Management System (CMS) components or products made of polymeric material(s). The determination is
made by combustion and subsequent analysis of the combustion product by Ion Chromatography. This
standard specifies how CMS components or products can be declared as halogen free.
This European Standard is for environmental performance only.
Compliance with this standard does not imply the absence of toxicity, corrosivity or opacity of produced smoke,
or other reaction to fire characteristics. If any of these characteristics are to be evaluated, the appropriate
standards can be used.
The detection limit of this test method is typically 0,025 g of halogen per kg (0,002 5 %).
Halides insoluble in aqueous solution present in the original sample or produced during the combustion step
are not determined by this method.
2 Normative references

requirements of this document. For dated references, only the edition cited applies. For undated references,

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http://www.electropedia.org/
— ISO Online browsing platform: available at http://www.iso.org/obp
3.1
halogen content
content of fluorine, chlorine, bromine and iodine as organic and inorganic compounds that can be converted
to halides (fluoride, chloride, bromide, iodide) by combustion and then absorbed or dissolved in an aqueous
solution
Note 1 to entry: The above definition is valid for this European Standard only and does not strictly comply with scientific
definition of halogen content.
4 Principle
The test sample is oxidized by combustion in a closed system containing oxygen under pressure using a
calorimetric decomposition bomb (bomb).
Nearly all of the halogens in compounds are converted to halides (fluoride, chloride, bromide and iodide), and
nearly all of these (see Clause 5) are dissolved in an absorption solution.
The detection limit of this test method is typically 0,025 g of halogen per kg (0,002 5 %). It may be used for
poorly burning samples, therefore a combustion enhancer may be used.
5 Interferences
5.1 General
Inorganic halides insoluble in aqueous solution present in the original samples or produced during the
combustion step are not determined by the method described here. 5.2 and 5.3 show the differences that
occur between the determination of the content of organic halogenated compounds and inorganic halogen

compounds. The inorganic halogen compounds in the material can have its origin as an additive deliberately
added to the material or as an impurity.
5.2 Organic halogen compounds
Organic compounds containing halogens are known under several names. Different expressions are used like
organohalogens, halogenated compounds, halocarbons or organic halides. They are all substances in which
one or more carbon atoms are linked by covalent bonds to one or more halogen atoms.
Among the organohalogens, some of them are efficient flame retardants. Chlorinated, brominated and
fluorinated organohalogens are used separately or in combination. Organohalogens will be converted into
inorganic halides by combustion and will then be absorbed or dissolved in an aqueous solution. This allows
the subsequent analysis of halogen content.
5.3 Inorganic halogen compounds
Inorganic compounds containing halogens are known as inorganic halides. Inorganic halides used as additives
are salts between a halogen and a metal linked together with an ionic bond, for example magnesium chloride
(MgCl2), potassium bromide (KBr) or sodium fluoride (NaF). These salts may have varying degrees of solubility
in water.
However, this limitation is considered as not significant as no example has been found where inorganic halides
have been used in CMS products.
Impurities containing inorganic halides will occur in several additives used in polymers. They can occur as
impurities in, for example, fillers (like CaCl2 in CaCO3), pigments (like TiCl4 in TiO2) or other inorganic additives
(like AlCl3 in Al(OH)3). These inorganic halides can have more or less solubility in water, but they will only be
measured if they dissolve in the aqueous solution. Investigations have shown that the content of each halogen
in impurities in inorganic additives for CMS products is low and therefore does not significantly contribute to
the total content of each halogen. Insoluble inorganic halides will not be considered and will not be measured
by the method described here. Examples of insoluble inorganic halides are halide salts of silver and barium
(AgCl, AgBr and BaCl2). Soluble inorganic halides will be dissolved in the aqueous solution and will be
measured together with halides coming from the combustion of the
...
