In the preliminary assessment, the test item boiled rapidly and then the residue produced grey fumes.

Results of the flash point determination are shown in the following tables:

Temperature (ºC)	Observations
25.0 (fresh sample) to 75.0^*	No flash for each temperature assessed.
75.0 (fresh sample) to 95.0*	No flash for each temperature assessed.
100.0 (fresh sample) to 130.0^*	No flash for each temperature assessed.
135.0	No flash was observed, the sample was boiling.
135.0 (fresh sample)	No flash was observed, the sample was boiling.
130.0 (fresh sample)	No flash was observed, the sample was boiling.
125.0 (fresh sample)	No flash was observed, the sample was boiling.
120.0 (fresh sample)	No flash was observed, the sample was boiling.
115.0 (fresh sample)	No flash was observed, the sample was boiling.
110.0 (fresh sample)	No flash was observed.
111.0 (fresh sample)	No flash was observed.
112.0 (fresh sample)	No flash was observed.
113.0 (fresh sample)	No flash was observed, the sample was boiling.
113.0 (fresh sample)	No flash was observed, the sample was boiling.
111.0 (fresh sample)	No flash was observed.

*Assessments in steps of 5 °C.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item can be considered as not a flammable liquid.

Executive summary:

The test item has been determined not to have a flash point below its boiling temperature,using a closed cup equilibrium method designed to be compatible with Method A.9 Flash Point ofCouncil*Regulation (EC) No 440/2008 of 30 May 2008and to satisfy the data requirements of Regulation (EU) No 528/2012, III, 4.6and Section 32 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria.The test item can be considered as not a flammable liquid.

The pile was not ignitable upon 2 minutes contact with a flame. The test substance melted but did not burn; therefore, no main test was performed.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

The test substance CIT was not ignitable with a flame.

Executive summary:

The flammability of 5 -chloro-2 -methy-2H-isothiazol-3 -one was investigated according to EU method A.10. A defined pile of the test substance was brought into contact with a flame.

No ignition of the test substance was observed upon a 2 -minutes contact with the flame.
