Version / remarks:

Screening procedure

Deviations:

no

GLP compliance:

no

Key result

Test procedure:

other: The sample in its delivery state and an inert reference sample are heated up to 380 °C at a rate of 0.5 K/min in an air flow of about 20 L/h.

Max. temp. reached:

380

Result:

negative outcome (no effect observed)

Remarks on result:

other: No exothermic effects were determined up to the point at which the test substance melted.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Norandrostendione is not a self-heating substance in the sense of CLP Annex I, 2.11.The determination according to UN-MTC Procedure N.4 (Bowes-Cameron-Cage-Test) is not necessary.

Reference 2

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2015

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

other: UN test procedure `Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria' (UN-MTC), Part III, sub-section 33.2.1.4.1, Test N.1 `Test method for readily combustible solids'.

Deviations:

no

GLP compliance:

no

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: The test substance melted when approached by the ignition flame. The substance did not burn up. No further testing was required.

The test substance melted when approached by the ignition flame. The substance did not burn up.

Interpretation of results:

non flammable

Remarks:

Migrated information not readily combustible solid

Conclusions:

The substance melted when approached by the ignition flame and also did not burn up.

Executive summary:

The substance in its delivery state melted when approached by the ignition flame. The substance did not burn up. Therefore estr-4 -ene-3,17 -dione is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1. No classification is needed.

Description of key information

a.) Flammability: The substance is a not readily combustible solid according to UN-MTC Procedure N.1.

b.) Pyrophoric properties: The substance did not deliver indications of pyrophoric properties during the realization of other tests. The determination according to UN-MTC Procedure N.2 is not necessary.

c.) Contact with water: The substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied.

d.) Self-heating substances: The substance is not a self-heating substance in the sense of CLP Annex I, 2.11.

Key value for chemical safety assessment

Flammability:

not classified
