(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/m3 = 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/m3).
(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. |
