- Specific details on test material used for the study:
- Test substance name: Isophthalonitrile
Chemical name: 1,3-dicyanobenzene
CAS number: 626-17-5
EC number: 210-933-7
LOT number: JB1906150101
Purity: 99.8 % (w/w %)
Appearance: Off white solid flakes
Manufacture date: 15 June 2019
Expiry date: 15 June 2020
Storage condition: Room temperature (15-25oC. below 70 RH%), protected from humidity
Safety Precautions: Routine safety precautions for unknown materials (lab coat. mask. gloves and safety glasses) were applied to assure personnel health and safety. - Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- Since the test item did not show ignition and did not propagate combustion during the 4 minutes test phase, it is classified as non-flammable.
Referenceopen allclose all
The test item was ground using a porcelain mortar. The sample mould was filled with the fine powdered test item. One end of the powder train was heated for 2 minutes with a hot flame using a gas burner, followed by 2 minutes-long observation period without heating. During the 4 minutes test period, the test item melted and carbonised, but no ignition or combustion was observed. According to the guideline, the test item shall be classified as non-flammable.
