  "text": "For substances that produce corrosive effects (R34, R35) or irritant effect (R36, R37, R38, R41), the individual concentration limits specified in Table IV determine, when appropriate, the classification of the preparation.\nTable IV\nClassification of the substance\nClassification of the preparation\nC with R35\nC with R34\nXi with R41\nXi with R36, R37 R38\n(*)According to the approved classification and labelling guide, when a substance or preparation is classified as corrosive and assigned the risk phrase R34 or R35, the risk of severe damage to the eyes is considered implicit and the risk phrase R41 is not included on the label. Consequently, if the preparation contains corrosive substances with R35 or R34 below the concentration limits for a classification of the preparation as corrosive, such substances can contribute to a classification of the preparation as irritant (R41) or irritant (R36).\nNote\nSimple application of the conventional method to preparations containing substances classified as corrosive or irritant may result in under-classification or over-classification of the hazard, if other relevant factors (e.g. pH of the preparation) are not taken into account. Therefore, in classifying for corrosivity consider the advice given in the approved classification and labelling guide regarding classification as corrosive and paragraph 4(4)(b) and (c) of Part I of this Schedule.\nC with R35\nconcentration ≥ 10% R35 obligatory\n5% ≤ concentration < 10% R34 obligatory\n5%\n1% ≤ concentration < 5% R36/38 obligatory\nC with R34\nconcentration ≥ 10% R34 obligatory\n10%\n5% ≤ concentration < 10% R36/38 obligatory\nXi with R41\nconcentration ≥ 10% R41 obligatory\n5% ≤ concentration < 10% R36 obligatory\nXi with R36, R37, R38\nconcentration ≥ 20% R36, R37, R38 are obligatory in the light of the concentration present if they apply to the substances under consideration",
