1 Any VOC not listed must produce an air concentration level no
greater than 1/100 the Threshold Limit Value (TLV) industrial work
place standard (Reference: American Conference of Government
Industrial Hygienists, 6500 Glenway, Building D-7, Cincinnati, Ohio
45211-4438) and/or no greater than 1/2 the CA Chronic Reference
Exposure Level (CREL)
(http://www.oehha.ca.gov/air/chronic_rels/AllChrels.html - (CRELs)
Adopted by the State of California Office of Environmental Health
Hazard Assessment (OEHHA), February 2005).
2 Formaldehyde criteria established so that emission levels
reach 0.014 ppm (13.5 ppb) within 14 days of installation (meeting
CA 1350 requirements).
3 Defined to be the total response of measured VOCs falling
within the C6 – C16 range, with responses calibrated to a toluene
surrogate.
4 Defined to be the total response of a specific target list of
aldehydes (2-butenal; acetaldehyde; benzaldehyde;
2,5-dimethylbenzaldehyde, 2-methylbenzaldehyde; 3-and/or
4-methylbenzaldehyde; butanal; 3-methylbutanal; formaldehyde;
hexanal; pentanal; propanal), with each individually calibrated to
a compound specific standard.
5 Defined to be the total response of a specific target list of
phthalates including dibutyl (DBP), diethylhexyl (DEHD), diethyl
(DEP), butylbenzyl (BBP), di-octyl (DOP), and dimethyl (DMP)
phthalates (conducted using a modified phthalate specific
analytical method, OSHA 104).
6 Particles applicable to fibrous, particle-releasing products
with exposed surface area in air streams (a forced air test with
specific test method).
