BS EN 15689:2009 PDF Download

BS EN 15689:2009 is a standard that pertains to railway applications, specifically track, switches, and crossings. It focuses on crossing components that are made of cast austenitic manganese steel. The standard aims to establish the material requirements for these components that are used in fixed crossings and cradles for crossings with movable parts. These components are designed to be welded or bolted to rails.

The standard also provides codes of practice for the inspection and testing of both un-machined and machined heat-treated castings. It includes methods for identifying and tracing crossings, as well as defining the limits of weld rectification by the supplier. Additionally, there are special requirements outlined for pre-hardened crossings.

It's important to note that BS EN 15689 does not cover geometrical aspects such as machining tolerances and inspection of finished crossings. These aspects are addressed in other related standards. Furthermore, the standard specifies the minimum requirements for cast manganese crossing components, but it acknowledges that certain special applications, such as tram systems, may require different demands. In such cases, agreements need to be made between the customer and the supplier.

The contents of BS EN 15689 include the scope, normative references, terms and definitions, quality systems, sample approval, general requirements, acceptance tests, additional requirements for pre-hardened crossings, weld rectification of surface discontinuities, identification and marking, and documentation. The standard also includes a section on non-common cast manganese crossings.
