A.

LIMIT VALUES FOR OCCUPATIONAL EXPOSURE

EC No, i.e. Einecs, ELINCS or NLP, is the official number of the substance within the European Union, as defined in Section 1.1.1.2 in Annex VI, Part 1, to Regulation (EC) No 1272/2008.
CAS No: Chemical Abstract Service Registry Number.
Measured or calculated in relation to a reference period of eight hours.
mg/m3 = milligrams per cubic metre of air at 20 °C and 101,3 kPa (760 mm mercury pressure).
ppm = parts per million by volume in air (ml/m3).
f/ml = fibres per millilitre.
Inhalable fraction: if hardwood dusts are mixed with other wood dusts, the limit value shall apply to all wood dusts present in that mixture.
Respirable fraction.
Substantial contribution to the total body burden via dermal exposure possible.
