6.2 For gases which produce such effects and for which specific concentration limits do not yet appear in the approved supply list, concentration limits laid down in Table VIA, expressed as a volume/volume percentage, shall determine, where appropriate, the classification of the preparation.
The following symbol and risk phrases are assigned:
| Carcinogenic categories 1 and 2: | T; R45 or R49 |
| Carcinogenic category 3: | Xn; R40 |
| Mutagenic categories 1 and 2: | T; R46 |
| Mutagenic category 3: | Xn; R68 |
| Toxic for reproduction fertility categories 1 and 2: | T; R60 |
| Toxic for reproduction development categories 1 and 2: | T; R61 |
| Toxic for reproduction fertility category 3: | Xn; R62 |
| Toxic for reproduction development category 3: | Xn; R63 |
| Classification of the substance (gas) | Classification of the gaseous preparation | |
|---|---|---|
| Categories 1 and 2 | Category 3 | |
(*) R68 here refers to substances classified as carcinogenic or mutagenic. Concentration limits for substances required to be labelled R68 but classified as harmful are given in Table IIA | ||
| Carcinogenic substances of category 1 or 2 with R45 or R49 | concentration ≥0.% carcinogenic R45, R49 obligatory as appropriate | |
| Carcinogenic substances of category 3 with R40 | concentration ≥1% carcinogenic R40 obligatory | |
| Mutagenic substances of category 1 or 2 with R46 | concentration ≥0.1% mutagenic R46 obligatory | |
| Mutagenic substances of category 3 with R68(*) | concentration ≥1% mutagenic R68(*) obligatory | |
| Substances “toxic for reproduction” of category 1 or 2 with R60 (fertility) | concentration ≥0.2% toxic for reproduction (fertility) R60 obligatory | |
| Substances “toxic for reproduction” of category 3 with R62 (fertility) | concentration ≥1% toxic for reproduction (fertility) R62 obligatory | |
| Substances “toxic for reproduction” of category 1 or 2 with R61 (development) | concentration ≥0.2% toxic for reproduction (development) R61 obligatory | |
| Substances “toxic for reproduction” of category 3 with R63 (development) | concentration ≥1% toxic for reproduction (development) R63 obligatory | |
