Annex ZA (informative) - Relationship between this European
         Standard and the Essential Requirements of EU
         Directive 96/48/EC of the European Parliament and
         of the Council of the 23 July 1996 on the interoperability
         of the trans-European high-speed rail system, as modified
         by EU Directive 2004/50/EC of 29 April 2004

Describes the following subjects: to establish a working terminology for expansion devices, for their constituent parts and for the types; to specify the minimum manufacturing requirements for expansion devices and their constituent parts; to formulate codes of practice for inspection and tolerances; to define the method by which expansion devices and their parts should be identified and traced.
