Hi (twice) !
Yes I know Stijloor. But it's always good to open our mind and vision. I would have been able to advise Abhissa to read the American standard ANSI/AIHA Z10, or the Canadian standard CSA Z1000 , or the other British standard BS 8800, etc.... But personally I prefer the international standard (and this standard is free of charge downloadable, but not the others).
Good day.
