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

Preliminary test:

Experimental conditions:

Atmospheric pressure: 98.3 kPa

Type of test item: Powder

Application of the flame: 2 minutes

Test period: 2 minutes

Assay No. 1:

The test item melted. Neither ignition nor propagation of the flame was observed.

Assay No. 2:

The same observations as for the assay No. 1 were recorded

Main test:

Taking into account the results obtained during the preliminary test, no main test was performed.

Interpretation of results:
other: The test item is not classified as a flammable solid of Division 4.1 and is thus not assigned to any packing group, under the experimental conditions. According to EC No. 1272/2008 (CLP), the test item is not classified.
Conclusions:
The test item is not classified as a flammable solid of Division 4.1.
Executive summary:

The flammability of phenyl 4 -hydroxybenzoate was determined by the test method N.1 for readily combustible solids. During the preliminary test neither ignition nor propagation of the flame was observed and thus no main test was performed. In conclusion, the test item phenyl 4 -hydroxybenzoate is not classified as a flammable solid of Division 4.1 and thus is not assigned to any packing group, under the experimental conditions used.
