sacks testing for UN approval

It is important that any bags or sacks which are used or sold for the transportation of dangerous goods are UN approved.  impact can offer sacks testing services to allow the approval of bags and sacks for the transport of dangerous goods.

Sacks tests involve the bag being subjected to drop impact tests to determine their suitability at retaining the hazardous substance inside upon impact.

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

sacks testing – what we need

A standard UN sack test can be carried out on 6 different bags.  These bags must come from the same batch and be identical in design and material to that of intended manufacture.

In addition to the sacks, we will need to know the material they are intended to carry.  In some cases we will require you to fill them with actual product, if there is no suitable placebo.  Finally we require a specification form which will form part of your certificate.

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 sacks, 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.
