54 New input for the final standard EN 555 Change from CEN-Standard procedure to a CEN TS Implementation of a special group (JWG/AEIF) for discussion of the standard text Restart of CEN-standard after carry out of CEN TS
55 New input for the final standard EN 555 European Fire safety Standards CEN TS 555 After the negative vote of the majority of the European member states of part 1 and part, the analysis shows, that the following arguments shall be taken into account. Ask for an advisory team containing CEN/CENELEC and AEIF responsibilities Word description of the operation categories in addition with the description of the interfaces to the infrastructure Eliminate the hazard levels Complete revision of part Technical specification The whole technical specification shall be voted completely
56 New input for the final standard EN 555 Guidance from Chairman and secretariat of CEN/TC 256 on new procedure with the JWG documents: work only on the English version until November 06 final versions have to be agreed by the JWG Part 5 is closed as a TS all parts are closed as TS May 2008 positive vote on complete CEN TS 555 start of the implementation stage
57 New input for the final standard EN 555 Open Points : After a resolution 17/0 the standstill is kept as the publication as TC is only an interim step before transformation of the whole series of TC into ENs. Therefore all 7 parts are changed into EN.
58 New input for the final standard EN 555 Open Points (continued) Support and guidance for toxicity testing methods. Checking both the individual and overall parts to achieve optimum security for persons in accordance with technical aspects. Consideration of system approaches for assessments according to Fire safety in Passenger vehicles. Assess the comments of pr TS Produce a transcript giving aid for a proposed end version off CEN TC 256
59 Actual Status All parts of the TS 55 have been accepted by the majority of the European national committees by an official vote. JWG proposed the following activities : -Give an application guide to all 7 parts of the TS 555 -Consider the system aspects for cables according to fire safety in rolling stock -Accreditation of Fire safety laboratories
