Cable management systems - Test method for content of halogens

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.

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

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

---------------------- Page: 7 ----------------------
SIST EN 50642:2018
EN 50642:2018 (E)

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
