Specifically, you asked\nwhether you may combine parts of the three test methods outlined in 49 CFR, Part 173, Appendix\nB.\nSection 173.24(e) requires that plastic packagings used for liquid hazardous materials be capable\nof withstanding without failure the procedure specified in Appendix B to Part 173. The\nprocedure must be performed on all packagings used to transport liquid hazardous materials in\nPacking Group I. However, for Packing Group II and III materials, capability to withstand this\ntest can be demonstrated through previous handling and transportation experience or design\nspecification.\nSection 173.24(e)(3)(iii) permits alternative procedures to determine compatibility and\npermeation rate if they yield a level of safety equal to or greater than provided by paragraph\n(e)(3)(ii) and are approved by the Associate Administrator for Hazardous Materials Safety. The\nprocedures for submitting an application for approval are prescribed in 49 CFR 107.705.\nI hope this satisfies your request. Please contact us if we can be of further assistance.\nSincerely,\nHothe z Mitchels\nHattie L.

Would it be permissible to combine parts of the three test methods? Specifically,\ncould the first and last 24 hours (container inverted) of the test be run at room temperature with\nthe specified period upright at one of the specified higher temperatures (50 or 60°C)? For\nexample, 24 hours inverted at 25°C, 14 days upright at 60°C, then 24 hours inverted at 25°. The\ngel has a tendency to leak out of the inverted container at 60°C but does not do so at 25°C.
