Evidence includes:<BR/><BR/>a. A crater at the test site, <BR/>b. Damge to the witness plate beneath the package<BR/>c. Measurement of a blast<BR/>d. Disruption and scattering of the confining material. <BR/><BR/>For Type B, a mass explosion indicates a Division 1.1 finding. Evidence includes:<BR/><BR/>a. A crater at the test site larger than that given by a single package<BR/>b. Damge to the witness plate beneath the stack which is appreciably greater than that from a single package<BR/>c. Measurement of a blast which significantly exceeds that from a single package<BR/>d. Violent disruption and scattering of most of the confining material. <BR/><BR/>You may be thinking of the Type C test, where if there are any perforations to the 3 witness screens erected in each three quadrants 4m from the packages, the finding will be Division 1.2.Cindyhttps://www.blogger.com/profile/12440811848067737195noreply@blogger.comtag:blogger.com,1999:blog-8945604944587027387.post-27478356714660581542008-11-19T16:00:00.000+08:002008-11-19T16:00:00.000+08:00It is not clear in thse tests that there is perfor...It is not clear in thse tests that there is perforation of the plate.<BR/><BR/>I cannot see any holes.<BR/><BR/>Under the UN Manual of Tests and Criteria detonation giving it a 1.1 rating requires there to be perforation or fragmentation of the steel witness plate.<BR/><BR/>Also the sequential explosions indicate that a detonation wave was not propagated.<BR/><BR/>Anthony Lealand<BR/>Firework Professionals Ltd<BR/>New ZealandAnonymoushttps://www.blogger.com/profile/03369232477865988066noreply@blogger.com
