352AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.311 DECEMBER 2001packaging. The quantities of different hazardous materials contained in each outer packaging must be such that "Q"is less than or equal to 1.0, "Q" is calculated using the formula:nl/Ml + n2/M2 + n3/M3 . . . = Q(nl, n2, etc. is the actual net quantity of each different hazardous material. Ml, M2, etc. is the maximum net quantitypermitted for the material and packing group in the outer packaging according to table A19.1.)For example:-There are 15 inner packages at 20 ml each of Class 3, PG II , and 5 inner packages at 30 ml each of Class 8,PG II in one outer packaging: 300 ml/500 ml + 150 ml/500 ml = 0.6 + 0.3 = 0.9. The result is lessthan 1.0, so the material can be shipped in one outer packaging.-There are 5 inner packages at 30 ml each of Class 3, PG II, and 15 inner packages at 30 g each of Class 8,PG II in one outer packaging: 150 ml/500 ml + 450 g/500 g = 0.3 + 0.9 = 1.2. The result is greater than1.0, so the item can not be shipped in one outer packaging.A19.2.12. Package Performance Tests. The complete package (inner plus outer packaging), must be capable ofwithstanding the test specified in A19.2.12.1 without breakage or leakage of the inner packaging and withoutsignificant reduction in effectiveness. Tests must be carried out on the packaging prepared as for transport. Innerreceptacles must contain at least 95 percent of their capacity for solids and 98 percent of their capacity for liquids.The material to be transported in the packaging may be replaced by another material, except where this wouldinvalidate the results of the tests. When another material is substituted for a solid, the material must have the samephysical characteristics (i.e., mass, grain size) as the material to be shipped. When another material is substituted inthe drop test for liquids, its relative density (specific gravity) and viscosity shall be similar to the material to beshipped.A19.2.12.1. For packaging with six sides (i.e., fiberboard box), the following free drops onto a solid, unyielding,flat, and horizontal surface from 1.8 m (6 ft) is required. Each test may be performed on different but identicalcontainers.-One drop flat on the bottom.-One drop flat on the top.-One drop flat on the long side.-One drop flat on the short side.-One drop on a corner at the junction of three intersecting edges.A19.2.12.2. For cylindrical packaging, the following free drops onto a solid, unyielding flat and horizontal surfacefrom 1.8 m (6 ft) is required:-One drop diagonally on chime or circumferential seam edge.-One drop on the weakest part (i.e., a closure) not tested by the first drop.A19.2.12.3. A force applied to the top surface for a duration of 24 hours, equivalent to the weight of identicalpackages if stacked to a height of 3 m (10 ft), including the test sample.HA19.3. Dangerous Goods in Limited Quantities.Limited quantities may be certified to this paragraph or to themost current ICAO Technical Instructions or IATA Dangerous Goods Regulation. Comply with all requirements ofthe document used including the inner packaging and outer packaging quantity limits. Pack limited quantities ingood quality combination packagings using only the inner and outer packaging combinations authorized. Thepackagings must also meet the general packaging requirements of attachment 3. Single packagings, includingcomposite packagings, are not permitted. The gross weight of a "limited quantity" package must not exceed 30 Kg(66 pounds). Quantity limits must not exceed the amounts authorized by table A19.2. If all the requirements of thisparagraph and the quantity limits of table A19.2 are met, the combination packaging need not meet (or be marked)with the UN packaging specification requirements.A19.3.1. Dangerous Goods not Permitted in Limited Quantities:-Materials forbidden in table A4.1.-Materials identified as “Cargo Aircraft Only” in table A4.1.-All materials in PG I.-Class 1 and 7 materials.-Class 2.3 and 6.2.-Class 2.1 materials (other than aerosols).-Refrigerated liquefied gases.
