impact are accredited to provide UN approval drum test (plastic and metallic) at our Scottish based facility.

UN drum test for UN marking

It is important that any UN drum which is used or sold for the transportation of dangerous goods is UN approved.  impact can offer UN drum test to allow the approval of drums (metallic, fibreboard or plastic) for the transport of dangerous goods.

UN drum test involve the drum being subjected to drop impact tests to determine their suitability at retaining the hazardous substance inside upon impact, stack tests for their long term storage and leak and hydraulic testing.

Once a UN drum has passed the testing, a report is prepared and an application made to the VCA-DGO who administer the UN marks for the UK.

UN drum test – what we need


The number of samples required for UN drum test varies depending on the contents to be carried in the drum and the method of closure.

For drums intended to carry solids we need 10 drums to complete the testing (stack, impact, leak and hydraulic) and for liquids a minimum of 13 drums are required.  If there is different cap types then there is a requirement to do extra testing.

It is always worthwhile having extra drums available in case of failures during the testing.

how it works

impact intend to make the UN approval system easy to navigate, and we can help handle all aspects of the process.

Once you have built your prototype drum, these should be sent to impact for the un approval testing to being.  We can either proceed directly to a full test, or, if you are still in the design stage, subject them to varying conditions to allow you to judge the future design.

After the full UN testing, if no failures have occurred, impact will provide a report to the VCA-DGO (Vehicle certification agency – dangerous goods office) who administer the UN marking scheme in the UK.  The VCA take 3 weeks to process a new application and will contact you directly for payment of application fees in order to issue the certificate.
