Scope: What is ISO 12856 ‑ 1 - Polymeric railway sleeper characteristics about? Polymer sleepers combine the best characteristics of timber and concrete – the lower rigidity of timber and the lifespan of concrete. ISO 12856 ‑ 1 is an International Standard that discusses railway applications in terms of polymeric composite sleepers, bearers, and transoms. ISO 12856 ‑ 1 is the first part of the ISO 12856 multi-series, and specifies the characteristics of polymeric composite and reinforced polymeric composite materials in the manufacture of polymeric composite railway sleepers. ISO 12856 ‑ 1 is applicable to sleepers, bearers, and transoms to be installed in all tracks (both heavy and urban rail) with or without ballast. In ISO 12856 ‑ 1 , the term “sleeper” refers to “sleeper, bearer, and transom”. Who is ISO 12856 ‑ 1
