Copper and copper alloy conductors also make electrical contacts

This Part of BS 3680 gives guidance on methods for sampling of both non-cohesive sand-bed material and cohesive-bed material (both of which may contain some fine gravel) principally for the purpose of determining the grain size frequency distribution of the bed material in open channels

of medium tolerance for use in chain slings according to EN 818‑4:1996+A1 and for general lifting purposes

As far as output characteristics are concerned

for example RADAR
