 Railway certification NF EN 15085

You are a manufacturer, sub-contractor or maintenance and repair workshop of railway vehicles or components ? We can accompany you through each of the key stages to achieve certification of your welding quality system.

Institut de Soudure Industrie has been recognised as a competent organisation by the French Ministry for Ecology, Energy, Sustainable Development and Town and Country Planning, for the certification of manufacturers under the EN 15085 series standards concerning welding in railway vehicles and components.

You will find here the list of certificates delivered by Institut de Soudure Industrie. These certificates are recognised world-wide, in particular with such major players as Alstom in France and DB – Deutsche Bahn in Germany.


Prior to certification and in order to prepare for it under the best possible conditions,

Our teams conduct an assessment of your company in order to identify any sensitive areas within your organization: listing the components manufactured; determining the level of safety required for each of those components; defining the performance intended for each of the welded joints.

We define with you an organization within your company, in accordance with the level of safety required.



We assist you for upgrading:

Training your personnel (visual inspection of welds, establishment of welding books etc.)

Qualification of your welders and welding operating processes

Training of co-ordinators within your company or provision of sub-contract co-ordinators.

In association with Association Française du Soudage (AFS), Institut de Soudure Industrie can organize in parallel, welding quality assurance certification of your company under NF EN ISO 3834.
