# Commission Directive (EU) 2017/164 of 31 January 2017 establishing a fourth list of indicative occupational exposure limit values pursuant to Council Directive 98/24/EC, and amending Commission Directives 91/322/EEC, 2000/39/EC and 2009/161/EU (Text with EEA relevance), Annex

Extent: E+W+S+N.I.

EC No European Community (EC) number, the numerical identifier for substances within the European Union.
CAS No Chemical Abstract Service Registry Number.
A skin notation assigned to the occupational exposure limit value indicates the possibility of significant uptake through the skin.
Measured or calculated in relation to a reference period of 8 hours time-weighted average (TWA).
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.
mg/m3 milligrams per cubic metre of air. For chemicals in gas or vapour phase the limit value is expressed at 20 °C and 101,3 kPa.
ppm parts per million by volume in air (ml/m3).
Inhalable fraction.
Respirable fraction.
Short-term exposure limit value in relation to a reference period of 1 minute.
