* For the category of substances marked with an asterisk, the summation rule applies. This means that the given
emission level applies to the sum of the substances in the relevant category plus those of the lower category.
** The different substances are classified below.
Classification of carcinogenic substances
Category Substance
C1 benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(j)fluoranthene,
benzo(k)fluoranthene, dibenzo(a,h)anthracene, 2-naphtylamine, 2-nitropropane, beryllium
(and compounds) as Be, chromium (VI) (and compounds) as Cr.
C2 3,3-dichlorobenzidine, diethylsulphate, dimethylsulphate, ethylene oxide, nickel (and compounds)
as Ni.
C3 acrylonitrile, benzene, buta-1,3-diene, 1,2-dibromomethane, 1,2-dichloroethane, epichlorohydrine,
hydrazine, propylene oxide, vinyl chloride.
Organic substances
The organic substances have been classified according to their ecotoxicity. Distiction is made
between gases/vapours and solids (gO and sO). The standard applies to the emission of the sum
of the substances (so called ‘summation rule’). Note that the classification as given above is not
complete (the total list includes several hundred components), but some relevant substances
have been included here.
