AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.3 311 11 DECEMBER 2001 A13.4.1. Inner Receptacle Requirements. - Limit Class 2 substances to aerosol products containing non-toxic solutions and compressed gases packed in inner non-refillable non-metal receptacles not exceeding 120 ml (4 Fl. oz) capacity each, or in inner non- refillable metal receptacles not exceeding 820 ml (28 Fl. oz) capacity each. Flammable aerosols must not exceed 500 ml (17 Fl. oz) capacity each). The following provisions apply to all aerosols under this paragraph: - The pressure in the aerosol must not exceed 1,500 kPa at 55^oC (217 psi at 130^oF) and each receptacle must be capable of withstanding without bursting a pressure of at least 1.5 times the equilibrium pressure of the contents at 55^oC (130^oF); - If the pressure in the aerosol exceeds 970 kPa at 55^oC (160 psi at 130^o F) but does not exceed 1105 kPa at 55^oC (160 psi at 130^oF), use an inner metal IP7, IP7A, or IP7B receptacle. - If the pressure in the aerosol exceeds 1,105 kPa at 55^oC (160 psi at 130^oF) but does not exceed 1245 kPA at 55 ^oC (180 psi at 130^oF), use an inner metal IP7A or IP7B receptacle. - If the pressure in the aerosol exceeds 1,245 kPa at 55^oC (180 psi at 130^oF), use an inner metal IP7B receptacle. IP.7B metal receptacles having a minimum burst pressure of 1,800 kPa may be equipped with an inner capsule charged with a non-flammable, non-toxic compressed gas to provide the propellant function. In this case, the pressures indicated above do not apply to the pressure within the capsule. The quantity of gas contained in the capsule must be so limited that the minimum burst pressure of the receptacle would not be exceeded if the entire gas content of the capsule were released into an aerosol. - The liquid content must not completely fill the closed receptacle at 55^oC (130^oF). - Each aerosol exceeding 120 ml (4 Fl. oz) capacity must have been heated until the pressure in the aerosol is equivalent to the equilibrium pressure of the contents at 55^oC (130^oF) without evidence of leakage, distortion or other defect. - Protect the valves by a cap or other suitable means during transport. - For aerosols containing a biological or medical preparation that will be deteriorated by a heat test and which are non-toxic and non-flammable, packed in inner non-refillable receptacles not exceeding 575 ml (19.4 Fl. oz) capacity each, the following provisions apply: - The pressure in the aerosol must not exceed 970 kPa at 55^o C (140.7 psi at 130^oF). - The liquid contents must not completely fill the closed receptacle at 55^o C (130^oF). - One aerosol out of each lot of 500 or less, must be heated until the pressure in the aerosol is equivalent to the equilibrium pressure of the contents at 55^o C (130^oF) without evidence of leakage, distortion or other defect. - Protect the valves by a cap or other suitable means during transport. - The following apply to Class 3 and Division 6.1 substances: - Inner packagings of Class 3 substances must not exceed 500 ml (17 Fl. oz). - Inner packagings of Division 6.1 substances must not exceed 500 ml (17 Fl. oz) for liquids and 500 g (18 oz) for solids. A13.4.2. Packaging Requirements. Inner packagings must meet the requirements of A13.4.1. Tightly pack inner packagings in strong outer packagings. UN specification packaging is not required. Each completed package as prepared for shipment must not exceed a gross mass of 25 kg (55 lb). - To prevent leakage during air transport, design and construct each packaging for changes in altitude and temperature. - Packaging (including closures) in direct contact with dangerous goods must not contain substances that may react dangerously with the contents, form hazardous products or weaken the receptacles. - Pack and cushion inner packagings that are breakable (such as earthenware, glass or brittle plastic) to prevent any breakage, leakage or movement within the outer packaging during transport. Provide absorbent material for glass or earthenware inner packagings in Class 2 or 3, or liquids of Division 6.1. Include sufficient cushioning material to absorb the liquid contents of the largest inner packaging contained in the outer package. Absorbent and cushioning material must not react dangerously with the contents of the inner packagings. Notwithstanding the above, absorbent material may not be required if the inner packagings are so protected that breakage and leakage of their contents from the outer packaging will not occur. These completed packagings must be capable of withstanding a 1.2 m (4 ft) drop on solid concrete in the position most likely to cause damage. - Leave sufficient ullage (outage) when filling receptacles for liquids to ensure that neither leakage nor permanent distortion of the receptacle will occur as a result of an expansion of the liquid caused by
