What is BS EN 13250 - Characteristics required for use in the construction of railways about?
BS EN 13250 specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of railways, and the appropriate test methods to determine these characteristics. BS EN 13250 provides for the assessment and verification of constancy of performance of the product to BS EN 13250 and for factory production control procedures.
Note1: BS EN 13250 applies in superstructure-ballast or substructure-blanket layer, within a subgrade.
Note2: BS EN 13250 is not applicable to geosynthetic barriers, as defined in EN ISO 10318-1.
Note3: Particular application cases may contain requirements regarding additional properties and – preferably standardized – test methods if they are technically relevant.
Note4: BS EN 13250 may be used to derive design values by taking into account factors within the context of the definitions given in EN 1997-1 (Eurocode 7), e.g., factors of safety. The design life of the product should be determined, since its function may be temporary, as a construction expediency, or permanent, for the lifetime of the structure.
Who is BS EN 13250 - Characteristics required for use in the construction of railways for?
BS EN 13250 on characteristics required for use in the construction of railways is useful for:
- Geotextiles and geotextile-related products manufacturers
- Railway management authorities
- Railway engineers
- Railway industry
- Site supervisors
- Inspection and testing department in railways 
- Railway construction companies
Why should you use BS EN 13250 - Characteristics required for use in the construction of railways?
The intended use of these geotextiles or geotextile-related products is to fulfil one or more of the following functions: filtration, separation, and reinforcement. The separation function will always occur in conjunction with filtration or reinforcement, and hence will not be specified alone.
BS EN 13250 allows manufacturers to describe geotextiles and geotextile-related products on the basis of declared values for characteristics relevant to the intended use and if tested to the specified method. BS EN 13250 also includes procedures for the assessment and verification of constancy of performance and factory production control.
BS EN 13250 helps to provide dimensional stability and is resistant to damage from railway construction stresses and ensures appropriate material selection for your railway construction project.
The aim of BS EN 13250 provides guidance, characteristics, and requirements of geotextiles and geotextile-related products which make ease construction of railways.
