Endpoint:
pyrophoric liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid
Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Endpoint:
self-heating substances / mixtures
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is completely molten at 160°C
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
Endpoint:
flammable solids

Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Lot/batch No.of test material: 0306-8715A
- Expiration date of the lot/batch: 2006-07

TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: The test item was grounded in a mortar.
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

The test item melted to a yellowish mass, but could not be ignited.

Conclusions:
The test substance was determined to be no flammable solid.
Executive summary:

A preliminary test according to Regulation EC 92/69, EU Test method A. 10 "Flammable solids" was performed to determine the flammability of the test substance. The test item was formed into a powder train. The flame from a gas burner was applied to one end of the powder train for 2 minutes. The burning of the pile was observed. The test was performed twice. In the preliminary test the test item could not be ignited. Based on the results of the preliminary test, no main test was performed. The test item is considered as a not readily combustible solid of Division 4.1. and is no flammable solid.

Description of key information

The test item is not classified as a flammable solid.

Based on its structure and experience in manufacture and handling the test item is not considered to have pyrophoric or self-heating properties or emit flammable gases in contact with water.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammability
A preliminary test according to Regulation EC 92/69, EU Test method A. 10 "Flammable solids" was performed to determine the flammability of the test substance. The test item was formed into a powder train. The flame from a gas burner was applied to one end of the powder train for 2 minutes. The burning of the pile was observed. The test was performed twice. In the preliminary test the test item could not be ignited. Based on the results of the preliminary test, no main test was performed. The test item is considered as a not readily combustible solid of Division 4.1. and is no flammable solid.

Pyrophoric solid

In accordance with section 2.10.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.2 the classification procedure for pyrophoric solids need not to be applied when experience in manufacturing or handling shows that the substance or mixture does not ignite spontaneously when coming into contact with air at normal temperatures. Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted and consequently the substance has not to be considered for classification as pyrophoric solid.

Substances which, in contact with water, emit flammable gases

In accordance with column 2 of REACH Annex VI and with Regulation (EC) No 1272/2008 Annex I section 2.12.4.1 the classification procedure for this hazard class need not be applied if:

a) The chemical structure of the substance or mixture does not contain metals or metalloids; or

b) Experience in handling and use shows that the substance or mixture does not react with water, e.g. the substance is manufactured with water or washed with water; or

c) The substance or mixture is known to be soluble in water to form a stable mixture.

The substance did not contain metals or metalloids. Therefore, the substance has not to be considered for classification as substances which, in contact with water, emit flammable gases.

Self-heating substances and mixtures

A study does not need to be conducted because the substance is completey molten at 160 °C.

Aerosols

A study does not need to be conducted because the substance is no aerosol.

Justification for classification or non-classification

In accordance with Annex I, Section 2.1, Section 2.2, Section 2.3, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008 and UN GHS Rev 6 (2015) the substance has not to be classified as readily combustible solid in class 4 Division 4.1, self-heating substance in Class 4 Division 4.2, substances which in contact with water emit flammable gases in Class 4 Division 4.3, pyrophoric liquid, pyrophoric solid in class 4 Division 4.2, flammable gases in class 2 or as aerosol in class 2.
