Safety Consulting Engineers, Inc. (SCE) has extensive test facilities and test equipment for conducting Standard UN testing on UN 1.6 explosive candidates, Insensitive Munitions (IM), and Extremely Insensitive Detonating Substances (EIDS). We conduct these tests at our remote, secure test site facility in western Illinois, which is authorized to handle up to 100-lb. of detonable or explosive substances. Our test site has both open-air and bunkered test areas to accommodate these tests. The Standard UN test methods below, are required to properly classify substances’ safety and performance.

To determine whether a material is an extremely insensitive explosive article, we conduct UN Test Series 7 tests and any candidate for Division 1.6 should pass one of each of the ten types of tests comprising the series (listed below). The first six types of tests [7(a) to 7(f)] are used to establish if a substance is an Extremely Insensitive Detonating Substance (EIDS); while the remaining four types of tests [7(g), 7(h), 7(j) and 7(k)] are used to determine if an article containing an EIDS (s) may be assigned to Division 1.6.

The ten test types are:

  • Type 7(a): a shock test to determine sensitivity to intense mechanical stimulus;
  • Type 7(b): a shock test with a defined booster and confinement to determine sensitivity to shock;
  • Type 7(c): a test to determine the sensitivity of the explosive substance to deterioration under the effect of an impact;
  • Type 7(d): a test to determin the degree of reaction of the explosive substance to impact or penetration resulting from a given energy source;
  • Type 7(e): a test to determine the reaction of the explosive substance to an external fire when the material is confined;
  • Type 7(f): a test to determine the reaction of the explosive substance in an environment in which the temperature is gradually increased to 365° C;
  • Type 7(g): a test to determine the reaction to an external fire of an article which is in the condition as presented for transport;
  • Type 7(h): a test to determine the reaction of an article in an environment in which the temperature is gradually increased to 365° C;
  • Type 7(j): a test to determine the reaction of an article to impact or penetration resulting from a given energy source; and
  • Type 7(k): a test to determine whether a detonation of an article will initiate a detonation in an adjacent, like article.
