Division 2.1.4.2 Screening procedure
United Kingdom
Explosive properties are associated with the presence of certain chemical groups in a molecule which can react to produce very rapid increases in temperature or pressure. The screening procedure is aimed at identifying the presence of such reactive groups and the potential for rapid energy release. If the screening procedure identifies the substance or mixture to be a potential explosive, the acceptance procedure (see section 10.3 of the F1UN RTDG, Manual of Tests and Criteria) has to be performed.
