    CEN/TC: European

    Objectives of the CEN/TC

     Elaboration of product performance standards in terms of thermal, fire, acoustic properties.

     Elaboration of design and application standards necessary to justify the performance above

    mentioned, as supporting standards.

    Strategies adopted to reach the Objectives

    1. Terminology

    Most of the product standards developed by the TC contain a clause on terminology, which is

    largely based on the existing publications.

    Within WGs, the work is mostly done in English but at the plenary meetings, the TC has

    agreed to have translation.

    2. Structure of the TC

    The TC has developed a structure into WGs according to the product types and to the

    manufacture processes.

    3. Liaisons

     Setting up a joint working group between TC 125 and TC 241 has not made the work easier;

     Internal liaisons has been established with horizontal (functional) TCs (TC 88, 89, 126, 127)

    or TCs dealing with building components where gypsum products are used (TC 51, 277, 303).

    Risk analysis

    The timely preparation of the ˇ°harmonized standardsˇ± does not only depend on CEN/TC 241 but

    also on the results of the work from other TCs. It especially depends on the availability of

    standards on the reaction and resistance to fire (TC 127), thermal properties (TC 89) and acoustic

    properties (TC 126). Also gypsum products are covered by different mandates which are

    sometimes overlapping each other.
