Ref: (a) NAVSEA letter Ser.. 03R42/454 o f 24 June 1996 "Authorization to Perform Qualification Testing on Chemguard's Fire Extinguishing Agent". (b) Military Specification, "Fire Extinguishing Agent, Aqueous Film-Forming Foam (AFFF) Liquid Concentrate, for Fresh and Sea Water," MIL-F-24385F, 7 January 1992. (c) Qualified Products List, QPL-24385-25, May 1992, which lists products that have been qualified in accordance with reference (b) 1. Chemguard Incorporated submitted a 3% Aqueous Film Forming Foam Fire Extinguishing Agent, designated as 3% AFFF C-301, Lot 061196A, to the Naval Research Laboratory (NRL) for qualification testing (reference (a)) for compliance with the requirements o f reference (b). Chemguard's 3% AFFF Lot 061196A passed the criteria required by reference (b) for qualification and inclusion in reference (c), except that it exceeded the cap opening torque required by paragraph 5.1.1.1.I f o f reference (b). The results o f the qualification testing that demonstrated compliance with the requirements are presented in Tables 1 through 7; the cap torque criteria that it was not in compliance with, and results o f the tests, are listed in bold, under lined print in Table 1, and outlined briefly below in paragraph 2a. 2-t The contents o f each Table are briefly outlined as follows, with a summary in 2a o f the failed criteria required by reference (b) for the cap opening torque. a.

Chemguard's concentrate was mixed individually with each o f the five concentrates in a 1:1 volume ratio, and with all the concentrates listed in Table 6 in a 1:1 volume ratio. These six concentrate mixtures were aged in accordance with reference (b) and then used to prepare the solutions used for fire performance testing. A slight cloudiness at the bottom of the container o f the mixture o f all the agent concentrates was noted. The cloudiness disappeared with agitation prior to mixing the working solutions.
