Article 8 - VOLATILE ORGANIC COMPOUND RULES
Rule 16 - Offset Lithographic Printing and Letterpress Printing
Section 16-6 - Compliance test methods
Current through March 20, 2024
Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-15; IC 13-17
Sec. 6.
(a) Compliance with the add-on control requirements shall be determined by performing emission tests as follows:
(b) VOC (alcohol) content of as-applied fountain solution shall be determined by using an accurate hydrometer to measure the alcohol content of the fountain solution. The hydrometer shall have a visual, analog, or digital readout with an accuracy of five-tenths percent (0.5%).
(c) VOC content of as-applied fountain solution or cleaning materials shall be determined in accordance with the following:
(d) Temperature requirements for refrigeration shall be determined with a thermometer or other temperature detection device capable of reading to five-tenths (0.5) degree Fahrenheit.
(e) The composite partial vapor pressure of a cleaning material shall be determined according to the following:
Where: Wi = Weight of the "i"th VOC compound, in grams
Ww = Weight of water, in grams
Wc = Weight of exempt compound, in grams
MWi = Molecular weight of the "i"th VOC compound, in g/g-mole
MWw = Molecular weight of water, in g/g-mole
MWc = Molecular weight of exempt compound, in g/g-mole
PPc = VOC composite partial vapor pressure at 20°C (68°F), in mmHg
VPi = Vapor pressure of the "i"th VOC compound at 20°C (68°F), in mmHg
