Test Method Stipulated in the Japanese Fire Services Law A

2 Test method stipulated in the Japanese Fire Services Law (A ) 

The purpose of this test is to evaluate the explosiveness of solid or liquid substances. For this purpose,measurements are made of the exothermic characteristics due to self-reactivity, such as the decomposition reaction induced in association with a rise in test article temperature. 

Use a differential scanning colorimeter (DSC) or differential thermal analysis (DTA) apparatus 1 with aluminium oxide ( a - alumina) as the reference substance. 

Set the hermetically sealed pressure cell 2 j containing a standard substance (lmg of DNT or 2mg of BPO) on the test apparatus, and heat at a rate of 10 0 C/min. Determine the exothermic start temperature and calorific value on the recording chart 4. Perform the test five times, and determine the average of the five runs. 

Same as (a) above except that the amount of sample is about 2mg (but modified according to the calorific value).
