3.5. Grouping of components in an interchangeable component group
Components may be grouped in a submission in an interchangeable component group provided that:
for all components in the interchangeable component group:
for all possible combinations of the resulting final mixture based on the components in the interchangeable component group, the hazards identification and additional information referred to in Section 2 of Part B are identical.
Alternatively, components that are classified only for skin corrosion, skin irritation, eye damage, eye irritation, aspiration toxicity, or respiratory or skin sensitisation, or a combination thereof, may be grouped in an interchangeable component group provided that:
the classification for health and physical hazards (hazard class and category) is identical for all components; and
the pH, where applicable, of all components classified for skin corrosion, skin irritation, eye damage, or eye irritation is either acidic, neutral or alkaline; and
the interchangeable component group does not contain more than five components; and
for all possible combinations of the resulting final mixture based on the components grouped in the interchangeable component group, the hazards identification and additional information referred to in Section 2 of Part B are identical.
3.5.1. Name of interchangeable component group and identification of grouped components
An interchangeable component group shall be given a name which corresponds to the technical function(s) of the grouped components for which they were incorporated in the mixture.
Each component in an interchangeable component group shall be identified in accordance with Section 3.2.1 or 3.2.2, as applicable.
3.5.2. Concentration and concentration ranges of grouped components
By way of derogation from the first subparagraph of Section 3.4, for components grouped in an interchangeable component group, submitters shall provide the information laid down in Sections 3.4.1 and 3.4.2 with regard to the total concentration of all components present in the mixture and grouped in the interchangeable component group.
When mixture components grouped in an interchangeable component group are classified in accordance with this Regulation for at least one of the hazard categories listed in Section 3.4.1, the total concentration of the components present in the mixture and grouped in the interchangeable component group shall be expressed as exact percentages, in descending order by mass or volume. As an alternative, a range of percentages may be submitted in accordance with Table 1 of that Section.
The total concentration of the hazardous components present in the mixture and grouped in an interchangeable component group that are not classified for any of the hazard categories listed in Section 3.4.1, and the total concentration of the identified components present in the mixture and grouped in an interchangeable component group not classified as hazardous, shall be expressed, in accordance with Table 2 of Section 3.4.2, as ranges of percentages in descending order by mass or volume. As an alternative, exact percentages may be provided.
