In the SLLSFAOB application note in section:
9.1.2 Intrinsic Safety The ISO7021 supports Intrinsically Safe (IS) to IS applications and carry IECEx and ATEX certifications. These devices do not currently support IS to non-IS galvanic isolation applications due to the minimum insulation thickness requirements of IEC 60079-11.
9.1.2.1 Schedule of Limitations These components are certified to comply with IEC 60079-0, Edition 7, IEC 60079-11, Edition 6, EN IEC60079-0:2018 and EN 60070-11:2012. When one of these components is used in an equipment, the component is to be soldered on a PCB inside a suitable enclosure and re-evaluated as an equipment. The operating temperature range of these components is -55°C to +85°C. The creepage and clearance distances across the isolating component have been evaluated, but the distance to other circuitry remain the responsibility of the user of the final equipment.
UL request a certification report, is it possible we can get a copy or send it directly the report to UL?
