Ammonium Nitrate Testing (Detonation Resistance Testing)

The HSE Science and Research Centre is a UKAS accredited testing laboratory [No.1751] for Ammonium Nitrate Detonation Resistance Testing (AN DRT).

The schedule can be viewed at: Testing Laboratory 1751

The Ammonium Nitrate Materials (High Nitrogen Content) Safety Regulations 2003 prohibit the importation, manufacture, supply or keeping of ammonium nitrate materials where the nitrogen content derived from ammonium nitrate is greater than 28% by weight unless the material has a certificate attesting that it has passed a Detonation Resistance Test (DRT) or is otherwise exempt.

This confirms that it has an appropriate degree of resistance to detonation.

Please e-mail TestingEnquiries@hse.gov.uk to discuss your DRT requirements.
