This part of IEC 61300 provides criteria for the visual and mechanical examination of fibre optic piece parts, connectors and passive components. The examination method may be used at any stage of the qualification or quality conformance inspection process, as a stand-alone test, or as required by the relevant specification. Visual examination of the polished end-face is defined in IEC/PAS 61300-3-35 and does not form part of this document.
