The sign of portion's content blast.One section of safe waiting time of test mechanism regulation should be observed after initiation, and test should carry out three
It is secondary, unless occurred conclusive result (such as whole content blasts) when earlier.If the test number (TN) of suggestion is obtained
The result that can clearly can't make an explanation, then test number (TN) should be increased.
Single parcel post tests the method for [6 (a) of test] assessment result --- represents if there is the sign of overall blast
Product is contemplated that and puts 1.1 under, and this sign includes:A there is a hole in () testing ground；B the witness plate below () parcel post is damaged
It is bad；C () measures shock wave；(d) closed material division and four dissipates.As fruit product is put into 1.1, then need not be in addition
Do experiment again；The test of type 6 (b) should otherwise be carried out.
The method of stacking test [test 6 (b)] assessment result is --- more than one parcel post or without the built-in of packing article
Thing actually instantaneously explodes, then product should put 1.1 under.The sign that this thing happens includes：The one of (a) testing ground appearance
Individual hole is much greater than single parcel post or without what is occurred in packing article test；Witness plate damaged condition ratio below (b) parcel post
Single parcel post is much greater without the damage caused in packing article test；C () measures shock wave and substantially exceeds in single bag
Part or without measuring in packing article test；(d) closed material division and four dissipates terribly.Otherwise, class is then carried out
The test of type 6 (c).
In the underground superficial test closed using loose sand, a heatable adobe sleeping platform is typically dug, checking iron plate and sample are put into
In hole, filled with loose sand.But after off-test, heatable adobe sleeping platform due to explode impact, situations such as easily there is fragmentation and disintegrate, it is impossible to
Tested next time in original soil hole, heatable adobe sleeping platform is excavated again can expend very big human cost and time cost.
