Paragraph 7
A package which includes thermal protection for the purpose of satisfying the requirements of the thermal test specified in paragraph 15 of Part III of Schedule 15 shall be so designed that such protection will remain effective if the package is subjected to the tests specified in paragraphs 6–11 and 14(a) and (b) or 14(b) and (c) of Part III of Schedule 15, as appropriate. Any such protection on the exterior of the package shall not be rendered ineffective by conditions likely to be encountered in routine handling or routine transport, or in accident conditions of transport, and which are not simulated in the tests referred to above, e.g., by ripping, cutting, skidding, abrasion, or rough handling.
