Product Description
Smoke Toxicity Hazard Classification Experiment with Mice Test Machine
Application:
The test equipment applicable to the smoke toxicity risk classification of materials for the stable production of smoke.It is suitable for the classification of smoke toxicity risk of material stable smoke production, but not for the classification of smoke toxicity risk of unsteady smoke production.
The GB standard USES mice to do experiments to determine the smoke toxicity risk classification of the material.
ISO standard USES the gas analyzer to determine the smoke toxicity risk classification of the material (the gas analyzer is optional for users)
Execution standard:
In accordance with GB/T20285-2006 material to produce smoke toxicity Hazardous classification, ISO19700-2006 "Controlled Equivalence thewire Method for the Determination of Hazardous Components of Fire Effluents,

Test preparation:
Sample size: the sample size needs to be able to put into the quartz boat and put into the ring furnace for heating. The inner diameter of the quartz boat is less than 30mm, so the sample size meets the following requirements: the length is 400mm, the width and thickness are not more than 20mm.At the same time, the sample mass size control is restricted by the flue gas flow, and it is best to control the sample mass loss to meet M= (5~10) C.
The samples should be made into uniform long strips, which can be spliced, and the powder experiment should be distributed evenly in the quartz boat.The test deformation material shall be prepared with chrome wire tied, and the granular material shall be evenly spread in the quartz boat.
8 samples were prepared for each group and randomly selected for test.Samples must be in temperature (23 + 2) ºC, relative humidity (50 + 5) % under the condition of adjustment to a constant weight or regulations adjustment cycle.
Test mice: the test mice were purchased from the unit with the experimental animal production license, which met the requirements of inbreeding or closed group, and were weighed in the laboratory for 2 days of adaptive feeding, with weight gain and meeting the requirements (21 + 3) g.
Number of mice: 8 mice were randomly divided into male and female groups.
Before the experiment, the experimental mice should be raised in IVC cages that meet the requirements of standard GB14925 "experimental animal facility environment". In the process of feeding, the cage-changing and mat material should be changed on the super-clean working table of the cage-changing.Keep the room clean and tidy.The mice were contaminated and could no longer be raised in IVC cages.Test mice drinking water, feed, pad materials purchased from qualified units and confirmed to meet the requirements.
During the experiment, the dead mice were frozen in the freezer. After observation for several days, the mice should be treated in time and frozen in the freezer. After a period of time, the mice were sent to Shanghai harmless treatment center for treatment.
