• Designed for developing emissions factors for constituents generated by the firing of small caliber ordnance: 5.56 to 40 mm
  
• The ECC is a cylinder with parabolic caps welded to each end. The chamber is approximately 7 feet in diameter, 15 feet long, and is constructed of 3/8-inch thick steel with a high-solids epoxy coating on all interior and exterior surfaces.
  
• A personnel access door and remotely operated firing port door are integrated into the rear and front parabolic caps, respectively
  
• A removable interior partition allows the test volume of the facility to be adjusted to approximately 213, 307, or 520 cubic feet depending on the physical size of the weapon to be tested and the expected quantity of emissions to be generated. The partition also allows the emissions generated from the breech of the weapon to be segregated from the emissions generated at the muzzle of the weapon if desired.
  
• A series of 12 ports, each 18 inches in diameter, are located along the sides and top of the chamber. The ports accommodate photographic, blast over-pressure, thermal, combustion product, and other instrumentation as required.
  
• High-volume fans located around the interior of the ECC, are used to homogenize the weapon emission products to enable accurate and reproducible sampling and analysis
  
• High speed video capability to capture blast events
  
• Supported by advanced analytical instrumentation, data collection, and on site chemistry lab facilities at ATC and U.S. Army Center for Health Promotion and Preventive Medicine (CHPPM)
  
• ATC utilizes samplings and analysis methodologies reviewed and approved by the U.S. Army Environmental Center and the U.S. Environmental Protection Agency
