Halogen Testing

Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), referred to as halogens. Since astatine is a radioactive element, the halogens often referred to only refer to: fluorine, chlorine, bromine and iodine. Halogens are widely used in flame retardants, refrigerants, solvents, organic chemical raw materials, pesticides and insecticides, bleaches, wool degreasing, etc. Zhongke Testing provides halogen testing services and has CMA and CNAS qualification certification.

Halogens are harmful, carcinogenic, and have adverse effects on the endocrine system and immune system. In general, it is harmful to the human body. According to many scientific studies, halogen flame retardants have become pollutants that spread everywhere in the daily environment, and are increasingly threatening the environment and humans.

1) EU 2011/65/EU - Restricted use of bromine-containing flame retardants (PBB≤1000mg/kg, PBDE≤1000mg/kg)
2) The global Montreal Protocol - restricting the use of 5 types of chlorofluorocarbons (CFCs) and 3 types of halons
3) The Stockholm Convention of 151 countries and organizations - restricts the use of organochlorine pesticides, hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs).
4) IEC printed board material regulations IEC61249-2-21 - requires PCB board base materials: chlorine (Cl) ≤900mg/kg, bromine (Br) ≤900mg/kg, overall halogen (Cl+Br) ≤1500mg/kg
