FOREWORD
This Indian Standard (Part 1) was adopted by the Bureau of Indian Standards, after the draft finalized by theExplosives and Pyrotechnic Sectional Committee had been approved by the Chemical Division Council.
An explosive is a compound or a mixture of compounds, which, when initiated by heat, impact, friction or shock,undergoes a very rapid self-propagating exothermic reaction. This reaction produces more stable products, usuallygases that exert tremendous pressure as they expand at high temperature.
Explosives can be classified into two broad groups, namely, the industrial explosives and the military explosives.Industrial explosives are also known as commercial explosives and include dynamites, slurries, emulsions andblasting powders. Military explosives are mainly used as ammunition in small arms as well as field guns androckets.
The nitroglycerine (NG) based explosives come under the category of industrial explosives. They were firstintroduced under the trade name of dynamites by Alfred Nobel, which was basically nitroglycerine absorbed inKieselguhr.
The nitroglycerine (NG) based explosives can be used at ambient and sub-zero temperatures. Under certainconditions, the nitroglycerine starts exuding from the explosive composition, creating safety hazards in thehandling and may cause severe headaches. This is particularly so, when nitroglycol is used in the explosivemixture.
The nitroglycerine (NG) content in explosives varies from as little as 5 percent to as high as 90 percent of thecomposition, according to the velocity of detonation, the energy release and the water resistance required forspecific applications.
This standard is the first in the series of Indian Standards on commercial blasting explosives. The other standardsin the series will follow.
There is no 1S0 specification on this subject. This standard has been formulated based on the data available forindigenous product.
The Committee responsible for formulation of this standard is given in Annex B.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standwd.

Measure the weight of the empty dry apparatus. Fillthe apparatus completely (up to the brim) with water,allow some time to escape air bubbles, if at all formed,and then measure the total weight of the apparatus.Now, empty the apparatus, and take again the weightmeasurement of the apparatus. Cut a slice of explosiveusing copper knife and place it (after removing itswrapper) in the empty apparatus. Measure the weightof the apparatus with explosive. Completely fill theremaining empty space of the apparatus with water andallow the air bubble to escape. Measure the weight ofthe apparatus containing explosive and water.
