EN 15287-1:2007+A1:2010 (E) 4 Introduction CEN/TC 166 started with its programme on standardization of chimneys approximately 15 years ago, with standards for interfaces, for products, for test and last but not least for design, installation, construction and commissioning matters. For the work program in the last years first priority had been given to product and test standards. In the meantime most of the product and test standards are published or nearly ready to be published. In order to introduce the products, which are tested and certified in accordance with the relevant European Standards, in an easy way on the markets of the different countries, some common rules for design, installation, and commissioning especially with reference to the designation of a chimney are helpful. Firstly CEN/TC 166/SC 2 started the work on execution standards for metal chimneys. The first standard had been already published as EN 12391-1 in 2003. In order not to repeat this work in all material oriented WGs and SCs, CEN/TC 166 decided in 2002 to give the task to WG 1 to develop a material independent design, installation and commissioning standard. CEN/TC 166/WG 1 started the work in 2003 and decided first to write two documents, one for chimneys connected to non-roomsealed heating appliances and one for chimneys connected to room-sealed heating appliances. Working on the documents there where two strong positions, one for a Technical Specification (TS) and one for a European Standard (EN). Following the proposal of CEN/TC 166/WG 1, CEN/TC 166 decided to launch a vote on the question which of the two positions should apply. The CEN/TC 166 members had been in favour of creating European Standards (EN).
