no
Key result
Relative self-ignition temperature:
600 °C
Remarks on result:
other: Submitted to a hot surface of ≥170ºC the substance decomposes (exotherm and smoke), "verpuffung" of the product can be expected. The autoiginition temperature of Halamid powder is 600ºC.

The Auto Ignition Temperature (AIT) of Chloramine-T is 600ºC. Submitted to a hot plate of 160°C Chloramine-T melts and decomposes slowly without a measurable thermal effect. Submitted to a 170ºC plate the material decomposes suddenly after about one minute. There is an exotherm and smoke ("verpuffung"). Therefore the Ingnition temperature (Tign), of Chloramine-T is 170°C.

Conclusions:
Submitted to a hot surface of ≥170ºC the substance decomposes (exotherm and smoke), "verpuffung" of the product can be expected. The autoiginition temperature of Tosylchloramide sodium, trihydrate powder is 600ºC.
Executive summary:

According to inhouse AkzoNobel methods the Auto Ignition Temperature (AIT) was determined. The Pruefer oven (or Godberg-Greenwald furnace) was used for the determination of the AIT of the product. The AIT of Tosylchloramide sodium, trihydrate powder is 600ºC. Submitted to a hot surface of ≥170ºC the substance decomposes (exotherm and smoke), "verpuffung" of the product can be expected

Description of key information
