Scope

This document specifies a test procedure to confirm that the force necessary to pull the anchorage of a rail fastening assembly out of the sleeper or other supporting element is greater than a prescribed value (i.e. it is a "proof load" test).
This test is for components of the fastening system which are:
a) cast into concrete during the manufacture of sleepers or other supporting elements;
b) glued into the cast or drilled holes in concrete; or
c) screwed or otherwise attached to wood, polymeric composite or steel sleepers or other supporting elements.
This test is not applicable to embedded rails.
