Test Requirement EU RoHS Directive (EU) 2015/863 amending Annex II to Directive 2011/65/EU- Lead, Mercury, Cadmium and Hexavalent chromium Signed for and on behalf of SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch Ford Shi Approved Signatory Conclusion Pass Test Report No.: SZXPC23001911609 Date: Aug 23, 2023 Page 2 of 5 Test Result(s): Test Part Description： SN ID Sample No. SGS Sample ID SN1 005 SZX23-0019116-0001.C005 Remarks: (1) 1 mg/kg = 1 ppm = 0.0001% (2) MDL = Method Detection Limit (3) ND = Not Detected (< MDL) (4) “-“ = Not Regulated Description Silvery metal EU RoHS Directive (EU) 2015/863 amending Annex II to Directive 2011/65/EU- Lead, Mercury, Cadmium and Hexavalent chromium Test Method: With reference to IEC 62321-4:2013+AMD1:2017, IEC 62321-5:2013 and IEC 62321-71:2015, analysis was performed by ICP-OES and UV-Vis . Test Item(s) Cadmium(Cd) Lead(Pb) Mercury(Hg) Hexavalent Chromium (Cr(VI)) ▼ Limit 100 1000 1000 - Unit(s) mg/kg mg/kg mg/kg µg/cm² MDL 2 2 2 0.10 005 ND 42 ND ND Notes: (1) The maximum permissible limit is quoted from RoHS Directive (EU) 2015/863. (2) IEC 62321 series is equivalent to EN 62321 series. (3) ▼ = a. The sample is positive for Cr(VI) if the Cr(VI)concentration is greater than 0.13 μg/cm2. The sample coating is considered to contain Cr(VI) b. The sample is negative for Cr(VI) if Cr(VI) is ND (concentration less than 0.10 μg/cm2). The coating is considered a non-Cr(VI) 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. Unless otherwise stated, the decision rule for conformity reporting is based on Binary Statement for Simple Acceptance Rule (w=0) stated in ILAC-G8:09/2019. Test Report No.: Date: SZXPC23001911609 Aug 23, 2023 ATTACHMENTS Elements Testing Flow Chart These samples were dissolved totally by pre-conditioning method according to below flow chart.
