Above statement led me to: FCC Supplier’s Declaration of Conformity (SDoC) - § 2.906 - ET Docket 15-170 - FCC 17-93,
Above led me to: EU Supplier’s Declaration of Conformity (SDoC) - ISO/IEC 17050-1:2004. Link to Nager IT PC Maus Konformitätserklärung by “encouraging humane working conditions in the factories of the electronic industries”.
Maybe someone experienced within field of SDoC creates separate topic, when suitable, on U.S. Conformity Assessment System (or broader) / Authorization of Radiofrequency Equipment because “SDoC may be an appropriate conformity assessment approach”. How is this related to CE marking, Japanese Giteki mark, etc. would be as well interesting to find out / get answer if applicable to Librem 5 (through SDoC approach, as “the market demands or allows it”).
