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
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: scientifically acceptable
Qualifier:
according to
Guideline:
other: Brennverhalten VDI 2263, Blatt 1, Kap. 1.2.
Qualifier:
according to
Guideline:
other: UN-Recommendations on the Tranport of Dangerous Goods, Manual of Tests and Criteria, 2nd revised edition, Part III, Test N.1, Abschnitt 33.2.1.4
GLP compliance:
no
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: The Preliminary screening test was negative, therfore the main test was not performed.

1.) Brennzahl bei Raumtemperatur BZ3, Brennzahl bei 100 °C BZ5.

2.) Pre-screening test negative, not easily igniteable.

Interpretation of results:
GHS criteria not met
Endpoint:
pyrophoric solids
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: scientifically acceptable
Principles of method if other than guideline:
other: measured (burning rate)
GLP compliance:
no
Key result
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition on contact with air (not further specified)

1.) Start of an exothermal reaction at 110 °C; maximum of the reaction at 145 °C; temperature rise 30 °C.

2.) Above 157 °C, formation of flammable gases

2.) In a closed glass vessel, no exothermal reaction occurs below 350 °C.

4.) Substance does not ignite when in contact with a glowing rod.

5.) Dust explosion potential.

Rationale for reliability incl. deficiencies:
other: scientifically acceptable
Qualifier:
according to
Guideline:
other: UN-Recommendations on the Transport of Dangerous Goods, Model Regulations, Section 2.4.3.2f and Manual of Tests and Criteria, Section 33.3
GLP compliance:
no
Key result
Test procedure:
100 mm sample cube at 140°C
Remarks:
The result was negative. Therefore, the test item is not subject to classification under Class 4.2.

During storage in 10 cm sample cube at 140 °C the result was negative. Therefore, the test item is not subject to classification under Class 4.2.

Interpretation of results:
GHS criteria not met

Description of key information

No pyrophoricity

Non flammable

No flammability on contact with water

Not self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Non pyrophoric, non flammable and not self-heating solid.

Based on the chemical structure and experience in handling and use, flammability on contact with water is not to be expected.

Justification for classification or non-classification

The available data on flammability, pyrophoricity and flammbility in contact with water do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC and are therefore conclusive but not sufficient for classification: Based on the chemical structure and experience in handling and use, pyrophoricity and flammability in contact with water are not expected.
