Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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
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. QA statement)

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.
