Käsitlusala:
This document specifies the terms and definitions used in the ISO 22074 series of standards related to rail fastening systems.
NOTE In this document, there are some entries where more than one term is listed in the header (e.g. sleeper, tie, cross tie in 3.2.3). In such cases, the first term is the preferred term, generally used in the ISO 22074 series of standards. The other terms are also in common use in the railway industry and are considered to be synonymous (admitted terms).

Railway infrastructure - Rail fastening systems - Part 7: Test method for clamping force and uplift stiffness (ISO 22074-7:2021)
Käsitlusala:
This document specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. When required, the procedure is also used to determine the uplift stiffness of the fastening system.
It is applicable to systems with and without baseplates on all types of sleepers, bearers or elements of ballastless track. The test does not determine the security of the fastening components fixed into the sleeper or other fastening system support.
This test procedure applies to a complete fastening assembly. It is not applicable to fastening systems for embedded rail or other fastening systems which do not act on the foot of the rail.

Railway infrastructure - Rail fastening systems - Part 3: Proof load test method for pull-out resistance (ISO 22074-3:2021)
Käsitlusala:
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.
