Dear Nattaya sanGood morning.Thank you for your response.I asked REACH-SVHC.Please ask OKI MICRO again.Please refer to "Data Entry Support Tool (ver. 2.00.00) Release note Appendix_EN.pdf".The following is an excerpt from that.IEC 62474 Ed 2.0:2018, the definition of an Article in the REACH regulation “An Article is an object that creates a specific shape, surface, or design that determines its function to be greater than its chemical composition during manufacturing” as well as the Court of Justice of the European Union decision on the interpretation of the SVHC denominator changed from product weight to component parts.
