Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 2014-06-17 to 2014-09-05
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
other: UN ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Part III: Classification Procedures, Test N.4: “Test Method for Self-heating Substances”,
Version / remarks:
(2009)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks on result:
other: No spontaneous ignition occurred and no exothermic effect of the test substance was observed in the test using a 100 mm sample cube at 140°C.

After the experiment, the test sample had turned into a hard white yellow lump. It indicated that the test substance had been decomposed and/or reacted during the experiment. 

 

Conclusions:
In a GLP-compliant study performed in accordance with UN-MTC Section 33.3.1 (Test N.4), the substance has been determined to be not a self-heating substance.
Executive summary:

Self-heating of test item was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”.

From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that CA-1S is not a self-heating substance.

Description of key information
