34AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.311 DECEMBER 2001-A single or composite packaging which is tested and marked for PG I liquid hazardous materials may befilled with:-A PG II solid hazardous material to a gross mass, in kilograms, not exceeding the rated capacity of thepackaging in liters, multiplied by 1.5, multiplied by the specific gravity marked on the packaging, or1.2 if not marked; or-A PG III solid hazardous material to a gross mass, in kilograms, not exceeding the rated capacity of thepackaging in liters, multiplied by 2.25, multiplied by the specific gravity marked on the packaging, or1.2 if not marked.-A single or composite packaging which is tested and marked for PG II liquid hazardous materials may befilled with a PG III solid hazardous material to a gross mass, in kilograms, not exceeding the rated capacityof the packaging in liters, multiplied by 1.5, multiplied by the specific gravity marked on the packaging, or1.2 if not marked. A3.2.Air-Eligible Packaging Requirements.A3.2.1. Combination Packaging Pressure Standard. Inner receptacles (including closures) used to retain ahazardous liquid or semi-solid in a combination packaging must be capable of withstanding (without leaking) aninternal air gauge pressure of not less than 95 kilopascal (kPa) (14 psi); or 75 kPa (11 psi) for PG III liquids in Class3 or Class 6.1 and Consumer Commodities; or a pressure related to the vapor pressure of the liquid contained in thereceptacle, whichever is greater. This standard may be determined through actual test data or the shipper’sevaluation and transportation experience. Repack or overpack liquid hazardous materials in containers that do notmeet the internal hydraulic pressure standard, into United Nations (UN) certified specification containers that meetthis requirement. Determine the pressure related to the vapor pressure of the liquid by one of the followingmethods:-The total gauge pressure measured in the receptacle (that is, the vapor pressure of the liquid and the partialpressure of the air, or other inert gases, less 100 kPa (15 psi) at 55 degrees C (131 degrees F), multiplied bya safety factor of 1.5. The total gauge pressure is determined on the basis of a filling temperature of 15degrees C (59 degrees F) and a degree of filling such that the receptacle is not liquid full at a temperature of55 degrees C (131 degrees F).-times the vapor pressure at 50 degrees C (122 degrees F) less 100 kPa (15 psi ).-times the vapor pressure at 55 degrees C (131 degrees F) less 100 kPa (15 psi).HA3.2.2. Single and Composite Packaging Pressure Requirement. Single packagings containing liquidhazardous material must meet the hydraulic pressure test requirements of 49 CFR 178.605. A test pressure of notless than 250 kPa (36 psi) for liquids of PG I; 80 kPa (12 psi) for PG III liquids in Class 3 or Class 6.1; and 100 kPa(15 psi) for all other liquids is required. If shipping liquid hazardous materials in containers that do not meet theinternal hydraulic pressure requirement, repack or overpack into UN specification certified containers that do meetthe requirement.A3.2.3. Overpacking Containers. Pack containers holding liquids that do not meet the pressure requirement forair transport into an outer container that does meet the requirement. Separate interior containers by absorbentcushioning material as required by attachment 20. Do not overpack pressurized containers in sealed metal drums.See Figure A17.1 for certification instructions.A3.3. General Requirements Applicable to Hazard Class. In addition to A3.1 and A3.2, the following generalrequirements apply to each hazard class:A3.3.1. Class 1.A3.3.1.1. Forbidden Explosives. Do not offer explosives listed below for air shipment:-An explosive that has not been approved according to A3.3.1.2.-Bulk fulminates or other detonating compounds in dry condition.-Explosive compounds that ignite spontaneously or undergo marked decomposition when subjected to atemperature of 75 degrees C (167 degrees F) for 48 hours.-An explosive mixture or device containing a chlorate and also containing:- An ammonium salt including a substituted ammonium or quaternary ammonium salt.- An acidic substance including a salt of a weak base and a strong acid.-Leaking, dropped, or otherwise damaged explosives and ammunition.
