4、Date Comments National foreword This British Standard is the official English language version of EN 772-13:2000, which is included in a package of new European Standards being prepared by CEN/TC 125 relating to masonry units made from clay, calcium silicate, aggregate concrete, and manufactured sto
5、ne. Although the English language versions of these European Standards will be adopted as British Standards as they become available, the existing British Standards for masonry units will be retained, but only until such time that the complete package of European Standards becomes available. Any res
6、idue(s) from British Standards affected by the package which need to be retained, will be drawn together to form a new British Standard. The original group of British Standards will then be withdrawn and this will be notified in Update Standards. The UK participation in its preparation was entrusted
