MDL Pentabromodiphenyl ether. - mg/kg. 5 ND Hexabromodiphenyl ether. - mg/kg. 5 ND Heptabromodiphenyl ether. - mg/kg. 5 ND Octabromodiphenyl ether. - mg/kg. 5 ND Nonabromodiphenyl ether. - mg/kg. 5 ND Decabromodiphenyl ether. - mg/kg. 5 ND Di-butyl Phthalate (DBP) mg/kg. 50 ND Benzyl Butyl Phthalate (BBP) mg/kg. 50 ND Di-2-Ethyl Hexyl Phthalate (DEHP) mg/kg. 50 ND Diisobutyl Phthalates (DIBP) mg/kg. 50 ND Notes :. (1) The maximum permissible limit is quoted from RoHS Directive (EU) 2015/863. IEC series is equivalent to EN series ,25 (2) = a. The sample is positive for CrVI if the CrVI concentration is greater than 0.13 μg/cm². The sample coating is considered to contain CrVI b. The sample is negative for CrVI if CrVI is ND (concentration less than 0.10 μg/cm²). The coating is considered a non-crvi based coating c. The result between 0.10 μg/cm² and 0.13 μg/cm² is considered to be inconclusive - unavoidable coating variations may influence the determination Information on storage conditions and production date of the tested sample is unavailable and thus Cr(VI) results represent status of the sample at the time of testing..
