4、to lead to CE marking. Thedate of applicability of EN 14992 as a harmonized European Standard, i.e. thedate after which this standard may be used for CE marking purposes, is subjectto an announcement in the Official Journal of the European Communities.The Commission in consultation with Member State
5、s has agreed a transitionperiod for the co-existence of harmonized European Standards and theircorresponding national standard(s). It is intended that this period willcomprise a period, usually nine months, after the date of availability of theEuropean Standard, during which any required changes to
6、nationalregulations are to be made, followed by a further period, usually of 12 months,for the implementation of CE marking. At the end of this co-existence period,the national standard(s) will be withdrawn.EN 14992 is the subject of transitional arrangements agreed under theCommission mandate. In t

34、bres covered by European Standards) may be used.“ !These wall elements“ may have external wall functions (see 3.11) or not, have facing functions (see 3.12) or not or have a combination of these functions. External wall functions could be: thermal insulation (see 3.11.1); sound insulation (see 3.11.
35、2); hygrometric control (see 3.11.3); or a combination of these. They may be plain, reinforced or prestressed. They may be loadbearing or not. These include: solid walls; composite walls; sandwich walls; lightened walls; claddings. The wall element may also work as a column or beam. 2 Normative refe
