Dear friends,

some standards, what I am interested for, have new editions or annexes. These standards are:
1. BS EN 480-1:2006+A1:2011 BS EN 480-1:2006+A1:2011 Admixtures for concrete, mortar and grout. Test methods. Reference concrete and reference mortar for testing
2. BS EN 480-13:2009+A1:2011 Admixtures for concrete, mortar and grout. Test methods. Reference masonry mortar for testing mortar admixtures
3. BS EN 490:2011 Concrete roofing tiles and fittings for roof covering and wall cladding. Product specifications
4. BS EN 491:2011 Concrete roofing tiles and fittings for roof covering and wall cladding. Test methods
5. BS EN 1110:2010 Flexible sheets for waterproofing. Bitumen sheets for roof waterproofing. Determination of flow resistance at elevated temperature

I'll be very thankful if someone who have them or could find them - share them. It is not very urgent.

Thanks in advance.
