What are the halogen-free specification requirements for anti-static rubber mat
What are the normative requirements for non-halogenation?
Different products have different limit standards, such as printed circuit board (PCB): chlorine Cl < 900PPM, bromine Br < 900PPM, bromine + chlorine < 1500PPM; such as non-PCB parts: bromine in brominated flame retardants < 900PPM, chlorine It is flame retardant or the chlorine in polyvinyl chloride (PVC) plastic is less than 900PPM. According to the requirements of the regulation IEC61249-2-21: the content of bromine and chlorine is less than 900ppm respectively, and the total content of bromine and chlorine is less than 1500ppm, which is halogen-free.
The halogen-free anti-static rubber products we produce do not contain fluorine, bromine, or iodine, and the measured chlorine content is more than 500 ppm. Many customers will conduct internal tests after receiving the samples of Chuangxuanbao halogen-free electrostatic leather. They may encounter unqualified data in the internal test results. Here is a friendly reminder as follows for screening and reference: anti-static rubber user spectrum scan It is possible to use the Xrf scanning method, which is the sample surface scanning test. There are errors between the measured results and the actual ones! From the summary statistics of the feedback from many customers we cooperate with, the approximate error is within 1000ppm (compared to the test results of the authoritative third party)!
The official feedback from the international authoritative third-party SGS company stated: SGS uses EN14582, and the samples need to be tested with IC after oxygen bomb combustion. This is the accepted method for testing for halogens. XRF scanning method is just a quick test method and is for reference only.
