What is ISO 12856‑2 about?
ISO 12856‑2 is an international standard for railway application that specifies the test methods which useful in verifying the performance and helps in accepting the Polymeric composite sleepers, bearers and transoms.
ISO 12856‑2 is the second part of railway application in multi-series.
ISO 12856‑2 specifies various test methods to ensure the performance of polymeric composite and reinforced polymeric composite sleepers, bearers and transoms for use in tracks. It is applicable to the sleepers, bearers and transoms to be installed in tracks with or without a ballast.
Note: ISO 12856‑2 is used as the technical basis for transactions between corresponding parties (purchaser – supplier).
Who is ISO 12856‑2 for?
ISO 12856‑2 on Railway applications is useful for:
- Railway authority
- Manufacturer of railways and tracks
Why should you use ISO 12856‑2?
Railway applications are useful in improving productivity and growth in the rail industry by applying management science techniques.
ISO 12856‑2 is useful in manufacturing of polymeric composite sleeper, bearers and transoms with the capacity to resist the bending for ballasted track. ISO 12856-2 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 12856‑2 is useful in evaluating the ignitability of the sleepers, bearers and transoms by conducting fire tests.
ISO 12856‑2 specifies the test methods and test procedures for conducting the test that determines the performance of Polymeric composite sleepers, bearers and transoms.
