Sampling procedures shall follow the guidelines presented in:
(a) ASTM D3925: Standard practice for
sampling liquid paints and related pigment coatings; or
(b) ASTM E300: Standard practice for sampling
The analytical methods and procedures
specified as follow shall be used to determine VOC content:
For coatings and for inks other than
solvent - borne (solvent reducible) publication rotogravure inks (See
Subparagraph (b) of this paragraph for explanation of solvent -borne (solvent
reducible) publication rotogravure inks.):
Reference Method 24 shall be used in the determination of total volatile
organic content, water content, and density.
To determine the total volatile organic
content, water content, and density of multicomponent coatings, the following
procedures shall be used in addition to Reference Method 24:
(i) The components shall be mixed in a
storage container in proportions the same as those in the coating, as applied.
The mixing shall be accomplished by weighing the components in the proper
proportion into a container which is closed between additions and during
mixing. About 100 ml of coating shall be prepared in a container just large
enough to hold the mixture prior to withdrawing a sample.
(ii) For determination of volatile content, a
sample shall be withdrawn from the mixed coating, and then transferred to a
dish where the sample shall stand for at least 1 hour, but no more than 24
hours prior to being oven dried.
(iii) For determination of the water content
and density of multicomponent coatings, samples shall be taken from the same
100 ml mixture of coating and shall be analyzed by the appropriate ASTM methods
referenced in Reference Method 24.
(b) Reference Method 24A shall be used in the
determination of total volatile organic compound (VOC) content and density of
solvent - borne (solvent reducible) publication rotogravure inks. A solvent -
borne publication rotogravure ink is an ink used in publication rotogravure
printing, as defined in Paragraph .35(2) of this chapter, whose volatile
portion consists essentially of VOC solvent with not more than five weight
percent water, as applied to the gravure cylinder.
The following ASTM method may be used as
an additional procedure related to determining VOC:
1. ASTM D4457-85: Standard test method for
determination of dichloromethane and 1,1,1 trichloroethane in paints and
coatings by direct injection into a gas chromatograph (the procedure delineated
above may be used to develop protocols for any compounds specifically exempted
from the definition of VOC).
(3) Use of an adaptation or alternative to
any of the analytical methods and procedures specified in Paragraph (2) of this
rule shall be approved by the Technical Secretary and the EPA on a case-by-case
basis. An owner or operator shall submit sufficient documentation to verify
that the analytical methods specified in Subparagraphs (2)(a), (2)(b), and
(2)(c) will yield inaccurate results and that the proposed adaptation is
appropriate, or that the proposed adaptation will yield results as accurate as
will the specified analytical methods.
Each sample collected for analysis shall
meet the following criteria:
(a) Each sample
shall be at least 1 pint taken into a 1 pint container at a location and time
such that the sample will be representative of the coating or ink, as applied
(i.e., the sample shall include any dilution solvent or VOC added during the
(b) If a
sample larger than 1 pint is obtained, the sample container shall be of a size
such that the sample completely fills the container;
(c) The container shall be tightly sealed
immediately after the sample is taken;
(d) Any solvent or other VOC added after the
sample is taken shall be measured and accounted for in the calculations in
Paragraph (3) of this rule; and
For multiple-component coatings, separate samples of each component shall be
Calculations for determining the VOC content of coatings and inks from data as
determined by Reference Method 24 or 24A shall follow the guidance provided in
the following documents:
(a) "A Guideline for
Surface Coating Calculations" EPA-340/1-86-016; and
(b) "Procedures for Certifying Quantity of
Volatile Organic Compounds Emitted by Paint, Ink and Other Coatings." (Revised
June 1986) EPA-450/3-84-019.
(6) In lieu of determining VOC content by the
methods and procedures specified in the other paragraphs of this rule,
formulation data shall be used if approved by the EPA and the Technical
Tenn. Comp. R. &
