What is ISO 12856‑3 - Polymeric composite railway sleepers about?
Polymer sleepers combine the best characteristics of timber and concrete – the lower rigidity of timber and the lifespan of concrete.
ISO 12856‑3 is an International Standard that discusses railway applications that specify the test methods which useful in verifying the performance and help in accepting the Polymeric composite sleepers, bearers, and transoms.
ISO 12856‑3 is the third part of the multi-series and specifies the general requirements of polymeric composite railway sleepers.
ISO 12856‑3 is applicable to the sleepers, bearers, and transoms to be installed in all tracks (both heavy and urban rail) with or without ballast.
Who is ISO 12856‑3 - Polymeric composite railway sleepers for?
ISO 12856‑3 on polymeric composite railway sleepers is useful for:
- Relevant railway authorities / Train operating companies (TOCs)
- Owners and managers of the rail transport networks
- Manufacturers and suppliers of rail components
- Manufacturers of polymeric composite railway sleepers
- Product design engineers
- Contractors / welders / welding supervisors
- Infrastructure managers
- Project managers
- Railway engineers
- Quality control and testing authorities
- Railway infrastructure regulatory bodies
Why should you use ISO 12856‑3 - Polymeric composite railway sleepers?
Newer materials in railway applications can improve performance and longevity.
ISO 12856‑3 is used as the technical basis for transactions between corresponding parties (purchaser – supplier).
ISO 12856‑3 is useful in the manufacturing of polymeric composite sleepers, bearers, and transoms with the capacity to resist the bending of the ballasted track. ISO 12856-3 guidelines help in determining the thermal expansion coefficient of the sleeper, bearer, or transom.
The Permanent deformation of the screw is used in fastening the system elements that are embedded or fixed into the sleeper, bearer, or transom. ISO 12856‑3 is useful in evaluating the ignitability of the sleepers, bearers, and transoms by conducting fire tests.
ISO 12856‑3 walks you through the geometrical design, mass, tolerances, quality control, documentation, and product testing of the railway.
ISO 12856‑3 specifies the test methods and test procedures for conducting the test that determines the performance of Polymeric composite sleepers, bearers, and transoms. ISO 12856‑1 contributes towards getting passengers and goods safely to their destinations.
