Protective Equipment Charcoal Testing

Charcoal testingEdgewood Chemical Biological Center’s (ECBC) Charcoal Testing Group of the Protective Equipment Team (PET) has been conducting charcoal testing at ECBC for over 75 years. Testing the integrity of charcoal for protective materials and filters has remained one of the primary missions of this center since the threat and use of chemical agents debuted. The testing capabilities in the Protective Equipment Team’s charcoal group have been expanded and renewed with the threat of global terrorism.

Charcoal samples and filters are analyzed using a variety of analytical techniques, to include gas chromatography, infrared spectroscopy, and inductive coupled argon plasma emission spectrometer. ASZM-TEDA carbon is regularly tested against military specifications and American Society for Testing of Materials Test Standards for the acceptance of product quality, using toxic chemicals, chemical warfare agents and physical challenges. The PET works jointly with other government agencies and contractors that produce charcoal filters for the United States military to certify the production process and end item integrity.

The PET is also capable of providing filter and service life surveillance of fielded items. The group can support various Joint Service program needs and developmental programs. First article testing and canister certification are among the Charcoal Testing Group’s diversified capabilities.

The PET charcoal group supports most of the nation’s manufactured charcoal, protective materials and filter products for issuance to the United States (US) soldiers and civilian personnel for protection against chemical threats. The charcoal group is an active and integral part of the US military’s protective equipment program and participates in performance and specification publications and standards.
