No, these went through the UN Series 6a,b, and c tests.
6a - put an igniter in one of the articles in a carton. Set on a steel witness plate. Contain with earth for 0.5m on all sides. Ignite. Observe. Based on the feebleness of the reaction, 6b may be waived. Remember that these tests are screening for assignment to 1.1, 1.2, 1.3, or 1.4, thus the use of the terminology of explosive effects.6b - multiple carton version of 6a. 6b determines if the explosive reaction (if observed) in the 6a test is sufficient to propogate the explosive effect to other packages in a stack.
6c - external bonfire test. In the bonfire test they actually do build a "standard" bonfire and put a case on top of it."This is a test on packages of an explosive substance or explosive articles, or unpackaged explosive articles, to determine whether there is a mass explosion or a hazard from dangerous projections, radiant heat and/or vilent burning or any other dangerous effect when involved in a fire."
Three vertical witness screes, 2m x 2m by 2mm thick aluminum, are placed at three quadrants, leaving the downwind side open.
Then they film it, observe it etc. The criteria between 1.3 and 1.4 involve such things as projectiles denting a witness plate 2m away, flame lengths, irradiance level, those sorts of things.
At the end of all this you get a recommendation for classification and a test report. The competent authority then reviews it and assigns a classification, normally based on the recommendation made by the testing agency, unless they have some specific objection in which case they can assign a more severe classification.
The details are all in the UN TDG Manual of Tests and Criteria.
