test is dimensionless, but it means that it is expected that it would take a greater impact to detonate it than PETN. Therefore, an experienced ordnance technician who works with raw PETN will know that the new explosive is not as sensitive with regards to impact. However, it could be more sensitive to friction, spark, or thermal issues. These conditions must be taken into account before any compound is to be stored, handled, or used in the field. Fireworks In the Netherlands, the Netherlands Organisation for Applied Scientific Research tests the safety of fireworks. According to a 2017 report by the Dutch Safety Board, 25% of all fireworks tested failed to meet safety standards and were banned from sale. Since 2010, safety testing of fireworks is required in the entire European Union, but companies are allowed to test their products in one member state before importing and selling them in another.
