The objective of this Standard is to provide purchasers and suppliers including owners, operators, designers and manufacturers of railway sleepers with requirements for the specification, manufacture and testing of alternative material sleepers for use in railway track.

This Standard is Part 22 of the AS 1085 (Railway track material) series.
This Standard specifies performance requirements for sleepers made from non-traditional materials, and the associated test methods to establish conformity.
The sleepers are for use in railway applications with continuously welded rail or jointed rail, and supported by ballast.
This Standard does not:
(a) include the design of bridge transoms or turnout bearers,
(b) specify manufacturing process, given the diverse nature of the materials used.
