PART 7

METHOD OF CALCULATING THE VOLATILE ORGANIC COMPOUND CONTENT OF REGULATED

1. The volatile organic compound content of regulated consumer products listed
in Parts 2, 3 and 4 shall be determined by Appendices A and B of Method 310
and using the equations set out in sections 2, 3 and 4 of this Part as may be
applicable.

2. If the regulated consumer product is—

   (a)  an aerosol product that does not contain LVP-VOC, the volatile organic
        compound content shall be calculated using the following equation—

Percent by weight of volatile organic compounds WL (TV － A － H － EL) ＋
WP － EP
= ————————————————— × 100
WL ＋ WP

where— WL represents the weight of the non-propellant portion in grams,
excluding packaging and container; TV represents the weight fraction of total
volatile material in the non-propellant portion, as determined by Method 24 or
Method 24A, ASTM D2369; A represents the weight fraction of ammonium in the
non-propellant portion, as determined by ASTM D1426 or Method 300.7; H
represents the weight fraction of water in the non-propellant portion, as
determined by ASTM D3792 or ASTM D4017; EL represents the weight fraction of
exempt compounds in the non-propellant portion, as determined by Method 8260B,
Method 18, ASTM D859, Method 1400; WP represents the weight of propellant in
grams, as determined by ASTM D3074 as modified in Appendix A of Method 310 for
metal aerosol container or ASTM D3063 as modified in Appendix A of Method 310
for glass aerosol container; EP represents the weight of exempt compounds in
propellant in grams, as determined by Method 18;

   (b)  an aerosol product that contains LVP-VOC, the volatile organic
        compound content shall be calculated using the following equation—

Percent by weight of volatile organic compounds WL [(1 － H)(1 － LVP) －
EL] ＋ (WP － EP)
= ———————————————————— × 100
WL ＋ WP

where— WL represents the weight of the non-propellant portion in grams,
excluding packaging and container; H represents the weight fraction of water
in the non-propellant portion, as determined by ASTM D3792 or ASTM D4017; LVP
represents the weight fraction of LVP-VOC compounds and/or mixtures in the
non-propellant, non-aqueous portion, as determined by ASTM D86, ASTM D850,
ASTM D1078, ASTM D2879 as modified in Appendix B of Method 310, ASTM D2887,
ASTM E1719, section 4 of this Part; WP represents the weight of propellant in
grams, as determined by ASTM D3074 as modified in Appendix A of Method 310 for
metal aerosol container or ASTM D3063 as modified in Appendix A of Method 310
for glass aerosol container; EL represents the weight fraction of exempt
compounds in the non-propellant portion, as determined by Method 8260B, Method
18, ASTM D859, Method 1400; EP represents the weight of exempt compounds in
propellant in grams, as determined by Method 18.

3. If the regulated consumer product is—

   (a)  a non-aerosol product that does not contain LVP-VOC, the volatile
        organic compound content shall be calculated using the following
        equation—

Percent by weight of volatile organic compounds
= (TV － A － H － EL) × 100

where— TV represents the weight fraction of total volatile material in the
non-propellant portion, as determined by Method 24 or Method 24A, ASTM D2369;
A represents the weight fraction of ammonium in the non-propellant portion, as
determined by ASTM D1426 or Method 300.7; H represents the weight fraction of
water in the non-propellant portion, as determined by ASTM D3792 or ASTM
D4017; EL represents the weight fraction of exempt compounds in the
non-propellant portion, as determined by Method 8260B, Method 18, ASTM D859,
Method 1400;

   (b)  a non-aerosol product that contains LVP-VOC, the volatile organic
        compound content shall be calculated using the following equation—

Percent by weight of volatile organic compounds
= [(1 － H) (1 － LVP) － EL] × 100

where— H represents the weight fraction of water in the non-propellant
portion, as determined by ASTM D3792 or ASTM D4017; LVP represents the weight
fraction of LVP-VOC compounds and/or mixtures in the non-propellant,
non-aqueous portion, as determined by ASTM D86, ASTM D850, ASTM D1078, ASTM
D2879 as modified in Appendix B of Method 310, ASTM D2887, ASTM E1719,
section 4 of this Part; EL represents the weight fraction of exempt compounds
in the non-propellant portion, as determined by Method 8260B, Method 18, ASTM
D859, Method 1400.

4. If the regulated consumer product is an aerosol product or a non-aerosol
product containing LVP-VOC under sections 2(b) and 3(b) of this Part, LVP-VOC
shall be determined according to the following steps—

   (a)  if the vapour pressure of a compound or mixture from product’s
        formulation data is unknown, ASTM D86, ASTM D850, ASTM D1078, ASTM
        D2879 as modified in Appendix B of Method 310, ASTM D2887 and ASTM
        E1719 may be used to determine the LVP-VOC of the compound or mixture;

   (b)  a sample of the LVP-VOC used in the product’s formulation shall be
        tested to determine the boiling point for a compound or for a mixture,
        and—

        (i)    if the boiling point exceeds 216°C, the compound or mixture is
               a LVP-VOC;

        (ii)   if the boiling point is equal to or less than 216°C, then the
               percent by weight of the mixture that boils above 216°C is a
               LVP-VOC;

        (iii)  the nearest 5% distillation cut that is greater than 216°C as
               determined under paragraph (a) shall be used to determine the
               percentage of the mixture qualifying as a LVP-VOC;

   (c)  if a product does not qualify as a LVP-VOC under paragraph (b), a
        sample of the compound or mixture used in a product’s formulation
        shall be tested utilizing one or both of the following methods for
        identification of LVP-VOC compounds and mixtures: ASTM D2879 as
        modified in Appendix B of Method 310, and ASTM E1719, to determine if
        the compound or mixture meets the definition of LVP-VOC.

5. In the case of floor wax stripper referred to in item 2 of Part 3, the
volatile organic compound content shall be calculated in accordance with the
test method and equations referred to in sections 1, 2, 3 and 4 of this Part
on the basis of the dilution ratio recommended on the products. “aerosol
