Council Directive 96/49/EC of 23 July 1996 on the approximation of the laws of the Member States with regard to the transport of dangerous goods by rail · European Union

6.2.3.4.6. The receptacles shall be thermally insulated. The thermal insulation shall be protected against impact by means of continuous pressure envelope. If the space between the receptacle and the pressure envelope is airless (vacuum-insulation), the protective pressure envelope shall be designed to withstand without deformation an external pressure of at least 100 kPa (1 bar). If the pressure envelope is so closed as to be gas-tight (e.g. in the case of vacuum-insulation), a device shall be provided to prevent any dangerous pressure from developing in the insulating layer in the event of inadequate gas-tightness of the receptacle or its fittings. The device shall prevent moisture from penetrating into the insulation.
