ANNEX I附則
ANNEX I Annex I to Directive 98/24/EC is replaced by the following: ‘ANNEX I LIST OF BINDING OCCUPATIONAL EXPOSURE LIMIT VALUES Name of agent EC No ( 1 ) CAS No ( 2 ) Limit values Notation Transitional measures 8 hours ( 3 ) Short-term ( 4 ) μg/m 3 ( 5 ) ppm ( 6 ) f/ml ( 7 ) μg/m 3 ( 5 ) ppm ( 6 ) f/ml ( 7 ) Diisocyanates (measured as NCO ( 10 ) ) 6 12 Skin ( 8 ) Dermal and respiratory sensitisation ( 9 ) A limit value of 10 μg NCO/m 3 in relation to a reference period of 8 hours and a short-term exposure limit value of 20 μg NCO/m 3 shall apply until 31 December 2028. ’. ( 1 ) EC No, i.e., Einecs, ELINCS or NLP, is the official number of the substance within the European Union, as defined in Annex VI, Part 1, Section 1.1.1.2, to Regulation (EC) No 1272/2008. ( 2 ) CAS No: Chemical Abstract Service Registry Number. ( 3 ) Measured or calculated in relation to a reference period of 8-hour time-weighted average (TWA). ( 4 ) Short-term exposure limit (STEL). A limit value above which exposure should not occur and which is related to a 15-minute period unless otherwise specified. ( 5 ) μg/m 3 = micrograms per cubic metre of air at 20 °C and 101,3 kPa (760 mm mercury pressure). ( 6 ) ppm = parts per million by volume in air (ml/m 3 ). ( 7 ) f/ml = fibres per millilitre. ( 8 ) Substantial contribution to the total body burden via dermal exposure possible. ( 9 ) The substance can cause sensitisation of the skin and of the respiratory tract. ( 10 ) NCO refers to isocyanate functional groups of the diisocyanate compounds.
