Requirements of an Ideal Delay Formulation

Some of the most important requirements of an ideal delay formulation with reproducible results are  

1) The formulation should be free flowing and should also be capable of being blended, filled and loaded in the delay device. 

2) The burning rate of the formulation must be uniform and reproducible. At the same time, its burning rate should not change with small variations in the proportions of ingredients. 

4) Its performance characteristics should not be affected significantly by changes in pressure and temperature. 

The formulations falling in the zone AA only are selected for actual Service use as these formulations satisfy one of the most important requirements of an ideal delay formulation that is, any minor change in the proportion of ingredients should not affect the burning rate adversely . The delay formulations are categorized in terms of IBR as shown in Table 5.8.
