UN Packaging codes reveal necessary information about a package\u2019s specifications.\u00a0\u00a0They provide concise answers to questions of:
\nwhat<\/strong> it can hold, how<\/strong> much, where<\/strong> it was authorized, when<\/strong> it was made, etc.
\nThe UN packaging code, however, doesn\u2019t always tell the whole story\u2026<\/p>\n

Although there may be other test levels achieved, these may not be reflected on the packaging itself.\u00a0 For example, take a steel drum that has successfully passed the most stringent tests (PG I), and is marked accordingly with the \u2018X\u2019 performance level.\u00a0 This package, in all probability, can\/has also passed the less rigorous tests required to meet both the \u2018Y\u2019 and \u2018Z\u2019 performance level. (Referencing a testing certificate, a test report, or the registration of a successfully tested package, will confirm this.<\/em>)
\n<\/p>\n

So what does this all mean?
\nFilling limits for single or composite packaging, containing less hazardous material for which they were tested & marked (e.g. PG III material in a PG I packaging), can be re-calculated as per below.<\/p>\n

Provided all the performance criteria can still be achieved by the higher relative density product, the following will apply:<\/p>\n

For liquids:<\/strong><\/p>\n

a.\u00a0 A packing group I packaging may be used for a packing group II material with a specific gravity not exceeding the greater of 1.8, or 1.5 times the specific gravity marked on the packaging.<\/p>\n

b. A packing group I packaging may be used for a packing group III material with a specific gravity not exceeding the greater of 2.7, or 2.25 times the specific gravity marked on the packaging.<\/p>\n

c. A packing group II packaging may be used for a packing group III material with a specific gravity not exceeding the greater of 1.8, or 1.5 times the specific gravity marked on the packaging.<\/p>\n

For Solids:<\/strong><\/p>\n

A single or composite packaging which has been tested and marked for liquids may be filled with solids to a gross mass not exceeding the capacity of the packaging in liters, multiplied by the specific gravity indicated in the package marking, or 1.2 if there is no indication in the marking.\u00a0 In addition,<\/p>\n

a.\u00a0 A single or composite packaging which has been tested and marked for packing group I liquids may be filled with a packing group II solid to a gross mass in kilograms not exceeding the capacity in liters multiplied by 1.5, multiplied by the specific gravity indicated in the package mark (or 1.2 if there is no indication in the marking).<\/p>\n

b.\u00a0 A single or composite packaging which has been tested and marked for packing group I liquids may be filled with a packing group III solid to a gross mass in kilograms not exceeding the capacity in liters multiplied by 2.25, multiplied by the specific gravity indicated in the package mark (or 1.2 if there is no indication in the marking).<\/p>\n

c.\u00a0 A single or composite packaging which has been tested and marked for packing group II liquids may be filled with a packing group III solid to a gross mass in kilograms not exceeding the capacity in liters multiplied by 1.5, multiplied by the specific gravity indicated in the package mark (or 1.2 if there is no indication in the marking).<\/p>\n
