compounds, in liters.
(d) Except as
specified in (e), below, the VOC content shall be calculated after thinning to
the manufacturer’s maximum recommendation by subtracting the weight of water
minus the weight of exempt compounds from the weight of VOCs and dividing that result by the result of subtracting the volume of
water minus the volume of exempt compounds from the volume of coating, as in
the formula below:
VOC Content = (Ws - Ww - Wec)
/ (Vm - Vw
- Vec)
(e) For low solids
coatings, the VOC content shall be calculated after thinning to the
manufacturer’s maximum recommendation by subtracting the weight of water minus
the weight of exempt compounds from the weight of volatiles and dividing the result by the volume of coating, as in the formula
below:
VOC Content (low solids) =
(Ws – Ww - Wec)
/ Vm

(a) To determine the
physical properties of an AIM coating in order to perform the calculations in
Env-A 4206.01, the manufacturer shall:
(1) Use EPA Method 24 as
described in 40 CFR 60, Appendix A-7, August 8, 2023, available as noted in
Appendix B;
(2) Use South Coast Air Quality
Management District (SCAQMD) method 304-91, February 1996, available as noted
in Appendix B; or
(3) Provide specific formulation
data.
(b) The manufacturer shall determine the exempt
compounds content using SCAQMD method 303-91, revised in February 1993,
available as noted in Appendix B.
(c) If there are any inconsistencies between the
results of EPA Method 24 and any other means for determining VOC content, the
EPA Method 24 result shall be used.
(d) The manufacturer shall use the following test
methods:
(1) ASTM test method E84-04,
2017, available as noted in Appendix B, to determine the flame spread index of
a fire-retardant coating;
(2) ASTM test method E119-00a,
2017, available as noted in Appendix B, to determine the fire-resistance rating
of a fire-resistive coating;
(3) ASTM test method D523-89,
2012, available as noted in Appendix B, to determine the gloss of a coating;
(4) SCAQMD method 318-95, July
1996, available as noted in Appendix B, to determine the metallic content of a
coating;
(5) ASTM test method D1613-03,
2017, available as noted in Appendix B, to determine the acid content of a
coating;
(6) ASTM test method D1640M-14,
available as noted in Appendix B, 2022, to determine the set-to-touch, dry-hard, dry-to-touch, and dry-to-recoat
times of a coating;
(7) The
Mechanical Test Method of ASTM test
method D1640M-14, 2022, available as noted in Appendix B, to determine the tack
free time of a quick-dry enamel coating;
(8) ASTM test method D4214-07,
available as noted in Appendix B, 2015, to determine the chalkiness of a
surface;
(9) Bay Area Air Quality
Management District (BAAQMD) method 43, May 18, 2025, available as noted in
Appendix B, to analyze exempt compounds that are cyclic, branched, or linear,
completely methylated siloxanes;
(10) BAAQMD method 41, available
as noted in Appendix B, May 18, 2025, to analyze the exempt compound parachlorobenzotrifluoride; and
(11) 40
CFR 59, Subpart D, Appendix A, June 30,1999, available as noted in
Appendix B, to determine the VOC content of methacrylate multi-component
coatings used as traffic marking coatings.
