Aside from the changes, the main technical changes are as follows.

a) The fire resistance rating "H" has been added (see 4.1);

b) Changed "Window Base" to "Main Window Frame" and "Window Frame" to "Window Sash Frame" (see 4.3 and examples of markings in various figures, 4.3 in the 2008 edition).

(and examples of markings in each figure);

c) A 450mm diameter specification has been added to the Type A window specifications (see Tables 3-8);

d) The major part designations and standard numbers have been changed (see Table 28, Table 26 in the 2008 edition);

e) The maximum allowable pressure for Type A specification 450mm has been increased (see Table A.1).
