105.1 Internal combustion engines with a manufacturers maximum continuous rating of 50 brake horsepower or less or gas turbine engines with a maximum heat input rate of 3,000,000 British Thermal Units (BTU) per hour or less at ISO standard day conditions. The ratings of all engines or gas turbines use in the same process shall be accumulated to determine whether this exemption applies.
105.2 Any combustion equipment that has a maximum heat input of less than 1,000,000 British Thermal Units (BTU) per hour (Gross) and is equipped to be fired exclusively with natural gas, liquefied petroleum gas or any combination there of, the ratings of all combustion equipment used in this process shall be accumulated to determine whether this exemption applies.
106 PLASTICS AND CERAMICS PROCESSING: The following plastics and ceramics processing equipment providing that emissions of volatile organic compounds do not exceed five pounds in any one day:
106.1 Ovens, kilns, or furnaces fired by electricity, and used exclusively for the heating, curing, softening, or annealing of plastics or ceramics. This exemption does not apply to equipment used for heating, or curing of fiberglass reinforced materials.

- ASTM D 2879-86, "Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope"; and
- ASTM D 1078-86, "Standard Test Method for Distillation Range of Volatile Organic Liquids".
