The UK participation in its preparation was entrusted by Technical Committee RAE/1, Railway applications, to Subcommittee RAE/1/-/9, Wagons (tank and freight), which has the responsibility to: A list of organizations represented on this subcommittee can be obtained on request to its secretary. The UK voted against EN 12561-8 at the adoption stage but BSI is obliged to publish it as a British Standard, in accordance with the CEN rules, as the result of the ballot was positive. The members of Technical Committee RAE/1 and Panel RAE/1/-/9 believe that: special attention should be given to the sealing faces and the locating recess for the tightening spigot shown in figures 2 and 3 to ensure that worn parts are replaced straight away to prevent leakage of high pressure steam operators emptying the wagon should take special care to avoid injury through contact with the hot surfaces of the heating connection while operating the wagon discharge valves which are located close by.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2004, and conflicting national standards shall be withdrawn at the latest by August 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports the objectives of the framework Directives on Transport of Dangerous Goods. This European Standard has been submitted for reference into the RID and/or in the technical annexes of the ADR. Therefore in this context the standards listed in the normative references and covering basic requirements of the RID/ADR not addressed within the present standard are normative only when the standards themselves are referred to in the RID and/or in the technical annexes of the ADR. This document is in compliance with the following regulations being in force on the date of approval of this EN : Regulations concerning the International carriage of Dangerous goods by rail (RID) 1) Regulations governing the reciprocal use of wagons in international traffic (RIV) 2) This document therefore supports essential requirements of 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 3) due to the fact that RID forms an integral part of this Directive.

In order to drain condensate the outlet shall be situated at the lowest point of the steam heating installation. This outlet shall not be obstructed when the outlet valve is open. It shall be directed to the ground in such a way as not to present a danger to personnel or damage on brake parts or to other wagon equipment. 5 Positioning of connections The connections shall be positioned entirely within the areas shown in Figure 1.
