Student Text IAFF Training for Hazardous Materials: Technician© Note: “X” containers must meet the most stringent standards and severe package testing requirements, thus any packing group can be shipped in “X” containers. Testing requirements include, but are not limited to: • Drop Test • Vibration Test • Leakproof Test and • Stacking Test. The severity of the test requirement is indicated by the material the package can contain. If the package is designed to contain a Packing Group I material, then the most stringent performance requirements must be met. For example, the performance standards for the drop test of an “X” package require that the container be dropped from a height of approximately six feet without leaking or denting. A “Y” package is dropped from a height of approximately four feet, and a “Z” package is dropped from a height of about two feet without denting or leaking. The most dangerous materials will be shipped in the strongest package. Part 4 Packages intended to house solid materials will be tested in accordance with a pre-determined statistical quality control plan. Packages intended to house a solid will have an “S” in box four. The number listed in conjunction with the “S” indicates the gross mass (in kilograms) to be housed by the package. In the following example, the container is intended for only a solid and the maximum gross weight associated with the container is 165 kilograms. S 165 If a package is designated to contain liquids, two numbers will appear in box four. The first number communicates the maximum specific gravity the container can hold. The second number communicates (in kilopascal) the pressure the container was tested under. 1.4 160 Module 1: Regulations 1-53
