3、ional foreword This British Standard is the official English language version of EN 13502:2002. EN 13502:2002 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M105, Chimneys, given under the EU Construction Products Direct
4、ive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 13502:2002 as a “harmonized” European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. EN
5、13502:2002 is the subject of transitional arrangements agreed under the European Commission mandate. The Member States have agreed a nominal transition period for the co-existence of EN 13502:2002 and their corresponding national standard(s). It is intended that this period will comprise a nominal n
6、ine month period during which any required changes to national regulations are to be made, followed by a further nominal twelve month period for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. In the UK, the corresponding national
7、 standard is: BS 1181:1999, Specification for clay flue terminals; and based on this transition period of twenty-one months, BS 1181:1999 would be withdrawn in July 2004 NOTE This date is approximate. Users of this standard should contact BSI Customer Services for confirmation of withdrawal. The UK
8、participation in its preparation was entrusted by Technical Committee B/506, Chimneys, to Subcommittee B/506/3, Chimneys and their components having inner linings of clay/ceramic, which has the responsibility to: A list of organizations represented on this subcommittee can be obtained on request to

It includes terminals used on dome
28、stic and industrial chimneys which are not structurally independent (free standing). This standard specifies the performance requirements for factory made terminals. Marking and inspection are also covered by this standard. 2 Normative references This European Standard incorporates by dated or undat
