Halogen test


Halogens include fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At), which are present in the VIIA family of the periodic table of chemical and physical elements. Halogens are often used in flame retardants, refrigerants, solvents, organic chemical raw materials, pesticides and insecticides, bleaching agents, wool degreasing, etc.


Common standards and regulations regulate halogens


(1) EU 2011/65/EU restricted substances: brominated flame retardants;


(2) Global "Montreal Protocol" restricted substances: five chlorofluorocarbons (CFCs) and three halons;


(3) 151 countries and organizations "Stockholm Convention" restricted substances: organochlorine pesticides, hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated Chlorodibenzofurans (PCDFs);


(4) IEC61249-2-21 Regulations for IEC printed board materials. z Maximum limit: chlorine, bromine, total halogen.


Different products have different limit standards for non-halogenated products


Such as halogen-free wire and cable, the halogen index is:


All halogen values ≦50PPM (according to regulation PREN 14582);


The content of hydrogen halide gas produced after combustion is less than 100PPM (according to regulation EN 5067-2-1);


The PH value of the hydrogen halide gas produced after combustion is dissolved in water ≧4.3 (weak acid) (according to the regulation EN-5 0267-2-2);


After the product is burned in a closed container, its transmittance is ≧60% through a beam of light (according to the regulation EN-50268-2).


Halogen-free requirements: bromine and chlorine content are less than 900ppm, (bromine + chlorine) less than 1500ppm.


Detection method


IPC-TM-650 2.3.28.2; BS EN 14582:2007 standard;


IEC 61249:2003 Part 2.21 (IEC 61189:2006-3);


JY/T 020:1996 General Principles of Ion Chromatography;
