Abel test
The Abel test is a common method of checking the quality of nitric acid esters - explosives such as nitrocellulose , nitroglycerin, and nitroglycol . The Abel test measures the chemical stability of these explosives.
The method was proposed by Frederick Augustus Abel in 1875 . The time is measured within which the gases evolved by 1 g of explosive at 82.2 ° C on a filter paper prepared and moistened with potassium iodide - starch solution turns blue or purple. In a more sensitive version, a zinc iodide solution is used. In the case of commercial explosives, this discoloration should occur after 10 minutes at the earliest.
