Easily trigger burning, blast, cause casualties, the serious consequence such as environmental pollution and property loss.The species of chemicals is various,
Using relatively extensively, chemicals progress correctly must be classified and be managed in fields such as its production, transport, identification, supervision.
There is the properties such as poison, burn into explodes, burns, be combustion-supporting in chemicals, there is harm to human body, facility, environment
Severe poisonous chemicals and other chemicals are referred to as hazardous chemical.At present, it is not higher than for dangerous material flash-point in closed cup test
60.5 DEG C or the liquid in open cup test not higher than 65.5 DEG C, sustained combustion experiment, the test of sustained combustion characteristic need to be added
Method mainly uses the United Nations《Recommendation model constitution on Dangerous Goods Transport》17th revised edition (first volume) the 2.3rd
The class flammable liquid part of chapter the 3rd, and《Manual of tests and criteria》Described in STSGAC.1011Rev.532.5.2 experiments L.2
" test method for determining sustained combustion "；In China, standard GB/T/T21622-2008《Dangerous material flammable liquid sustained combustion
Test method》Referring generally to above-mentioned the United Nations's standard method.During experiment described in standard, experimenter is by a certain amount of examination
Test sample to be placed in sample groove, then removed after applying the flame of certain time at the regulation and whether viewing test sample can be held
Afterflame burns.The incendiary source used at present in standard is the gas arc lamp using butane as fuel, there is certain safety to testing crew
Hidden danger；And total Test personnel's manual switching, it is less efficient.
In summary, during substance combustion screening test is screened, generally require fast and effectively to judge flammability
As a result, thus improve experiment automatization level be necessary, automatic test effectively increase testing efficiency safety
Property, there is wide application prospect.
