Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 9 dec 2008 to 27 march 2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
yes
Remarks:
The ignition source is a platinum wire heated by electrical power instead of a direct flame. This deviation is judged to have no effects on the results.
GLP compliance:
yes (incl. certificate)

The test item did not burn. It melted in contact of the ignition source, ignited slightly- not spread of the flame. No further testing was required.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
4-tert-butylpyrocatechol is not "highly flammable" under the conditions of the test.
Executive summary:

In a study (CRTL, 2009), the flammability of 4 -tert-butylpyrocatechol was performed according to the regulation (EC) n°440/2008, A.10.

The test item did not burn. It melted in contact of the ignition source, and no further testing was required.

4 -tert-butylpyrocatechol is not "highly flammable" under the conditions of the test and according to the EC A.10 criteria.

This study is classified as acceptable and satisfies the guideline requirements for a flammability study.

Description of key information

4-tert-butylpyrocatechol is non flammable when tested according to A10 method.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

One experimental study (CRTL, 2009) with reliability 1 according to Klimisch was available and was selected as key study. Flammability was determined according to the regulation (EC) n°440/2008, A.10.

The test item did not burn. It melted in contact of the ignition source. No further testing was required.

In these conditions, 4-tert-butylpyrocatechol was considered as not highly flammable.

Justification for classification or non-classification

4-tert-butylpyrocatechol is non flammable when tested according to A.10 method, so it is not classified according to EU classification criteria.
