Izpostavljenost na delovnem mestu - Ugotavljanje prisotnosti mikroorganizmov v zraku in merjenje njihovih metabolitov - Splošne zahteve

Ta evropski standard določa splošne zahteve za ugotavljanje prisotnosti mikroorganizmov v zraku in merjenje njihovih metabolitov. Ta evropski standard podaja tudi smernice za oceno izpostavljenosti na delovnem mestu zaradi mikroorganizmov v zraku, vključno z določanjem skupnega števila in števila mikroorganizmov, sposobnih tvorbe kolonij, ter njihovih metabolitov v zraku na delovnem mestu.

The major technical changes between this European Standard and the previous edition are as follows:
a) document title changed;
b) list of measurable bioaerosol compounds extended;
c) new measuring techniques added;
d) new definitions for “allergen”, “cell count of microorganisms”, “glucan”, “microbial compound”,
“mycotoxin”, and “RFc-recombinant” added;
e) existing definitions technically revised, where necessary;
f) terms and definitions already referred to in EN 1540 deleted;
g) 5.3 on “Measurement strategy” improved by providing more details;
h) Annex A updated with regard to new techniques and methods;
i) Annex B updated with new compounds that can be measured;
j) Annex C updated with regard to new counting strategies and identification methods;
