Add the following references:
"EN 772-2, Methods of test for masonry units — Part 2: Determination of percentage area of voids in masonry
units (by paper indentation)
EN 772-20, Methods of test for masonry units — Part 20: Determination of flatness of faces of masonry units

unreinforced masonry structures
EN 1996-1-2, Eurocode 6: Design of masonry structures — Part 1-2: General rules — Structural fire design"
Amend the title of reference EN 772-9 by deleting "calcium silicate" and substituting "clay and calcium
silicate.”
2 Modification in 3.14 frog
Delete "both faces" and insert "both bed faces".
3 New 3.24 combined thickness of webs and shells
Add the following new definition:
"3.24
combined thickness of webs and shells
sum of the thicknesses of the shells and webs from one face or header of a masonry unit to the opposite face
or header respectively along whichever path, via the formed voids, gives the smallest value, expressed as a
percentage of the unit width or length respectively
4 Modification in 5.2.1 Dimensions and tolerances
st
In the penultimate paragragh, end of 1 sentence, delete “5.2.2” and substitute “5.2.2.1”.
5 Modification in 5.2.2 Tolerances

the mean length, width and height and the actual deviations for individual length, width and height shall be not
greater than the permissible deviations as specified in Table 1 for the declared dimensional tolerance
category."
