3 Terms and Definitions
GB/T 19267.1 and GB/T 20162 defined and the following terms and definitions apply to the GB/T 18294 this document.
3.1
Characteristic frequency region characteristicfrequencyregion
Fire scene organic residue having a spectrum at 4000cm-1 ~ 1250cm-1 region.
3.2
Fingerprint region fingerprintregion
Fire scene organic residue having is within 1250cm-1 ~ 400cm-1 spectral region.
Principle 4
When the infrared light is irradiated to the fire scene organic residues, the infrared light is absorbed by a certain frequency of the vibration frequency of the same bond yield
Health and energy transition. Different structures composed of different substances, absorption of infrared light is different, based on the structure of this feature can be of unknown composition of
Identification.
5 Test conditions
5.1 condition setting
