According to the CENICENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
20、 Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The requirements are incorporated in the appropriate Product Standard. This draft European Standard is based on the results of extensive research and inter-laboratory testing compa
21、ring artificial and natural weathering. From the results it was concluded that the requirements for the retention of mechanical properties after long term artificial weathering were best defined using one method, and Charpy impact strength testing was chosen. In addition, the spray cycles for modera
22、te and severe climates have been chosen. Annex A, which is informative, gives the reasons for the choice of exposure conditions. This standard reflects the state of the art at the time of publication. Further research may necessitate amendments to this standard. O BSI 12-1999 STD-BSI BS EN SL3-ENGL
