Overview
This document specifies a laboratory test procedure for determining the electrical resistance, in wet conditions, between the running rails provided by a fastening system fitted to a steel or concrete sleeper, bearer or element of ballastless track. It is also applicable to embedded rail. This test procedure applies to a complete fastening assembly. It is relevant to signalling currents, not to traction currents. A reference procedure and an alternative procedure are included. The responsible national standardization committee is Subcommittee NA 087-00-01-04 UA "Schienenbefestigungssysteme" ("Fastening systems") at DIN Standards Committee Railway (FSF).
