In accordance with ASTM E2008, “Standard test Method for Volatility Rate by Thermogravity,” measure the average volatility rate of the cleaner and of a control sample of n-butyl acetate. The volatility rates shall each be the average of three measurements, each measurement performed at a constant temperature of 50°C. Divide the average volatility rate of the cleaner by the average volatility rate of n-butyl acetate to obtain comparative volatility ratio.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel components are to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activities within the Military Service or Defense Agency, or within the military service’s system commands. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
