Font and font size

The standard font for all IEC material is Arial, alternatively Helvetica, automatic (black) colour, single line spacing, justified left/right without word break. The standard size is 10

For texts which are laid out in columns there should be flexibility as to whether word break is used or not [see Hyphen usage]
