Dutch Stability Test. This test, which may be considered as a modification of "Simon Thomas Fume Test , was devised in 1920 by Van Duin and Van Lennep (Ref 1). Here the loss of weight on hearing of a propellant (or explosive) served as a criterion of stability...

An explosive is considered harmless if the first test produces a maximum of 32 I carbon monoxide and a maximum of 4.0 I nitrous gases per kg of explosive. If the result for carbon monoxide exceeds 32, but not 40 I per kg of explosive or the result for nitrous gases is over 4.0 but not over 5.0 I per kg of explosive, the fume test must be repeated. The mean values for carbon monoxide and nitrous gases from the results of the first and the second test must not exceed 40 I of carbon monoxide per kg of explosive and 5.0 I of nitrous gases per kg of explosive.

Cyanoacrylates are also used by forensic scientists to collect fingerprints at crime scenes. The object to be tested is suspended inside a container with at least one transparent side. A few drops of Super Glue or similar cyanoacrylate product is added to the container and the container is sealed and heated to about ioo°C (2i2°F). That heat causes vaporization and polymerization of the cyanoacrylate, resulting in the formation of distinctive white print patterns, a process that make take two hours or more. This cyanoacrylate fuming test has now become the procedure of choice for the detection of latent prints deposited on non-porous objects, such as glass, plastic, rubber, and leather. 

The use of PVC in cable in Europe may be affected if the EU s Fire Regulatory Committee incorporates an optional provision for an acid fume test in its construction products directive, as mged by Sweden.
