Dear all,

I have to compare the english and german notations for analytical gases
(esp. oxygen or helium). Surprisingly, I could not get this information from
german companies.
Could anybody of you give me the german grade of purity (5.6 or 4.5) which
corresponds to the english cp-grade.

Many thanks in advance
        Andreas
