Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
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:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
14 Jul 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Qualifier:
according to guideline
Guideline:
other: VDI 2263, sheet 1
Version / remarks:
1990
GLP compliance:
not specified
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
151 s
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

Preliminary Test

The burning time over a distance of 200 mm is 151 s. This is above the threshold of the burning time of 2 minutes to UN Transportation Regulation and GHS / CLP Regulation. Therefore the main test had not to be performed.

 

Main Test

In the preliminary test the burning time over a distance of 200 mm was 151 s. Thus, the performance of the main test was not necessary.

 

Final Results

The burning time over a distance of 200 mm is 151 s. This is above the threshold for classification.

The test item is classified as follows:

UN Transport Regulation: The test item has not to be classified as readily combustible solid in class 4.1 according to the UN Transport Regulation.

GHS (CLP Regulation EC 1272/2008: Annex 1: 2.7): The test item has not to be classified as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.

Description of key information

non flammable

no pyrophoricity

no flammability on contact with water

not self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The substance is not flammable according to UN Test N.1.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.

The substance is completely molten at a temperature below 160 °C, self-heating behaviour does not need to be determined.

Justification for classification or non-classification

The substance is not flammable according to UN Test N.1 and has not to be classified as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.

The available data on flammability in contact with water, pyrophoricity and self-heating of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.

The substance is completely molten at a temperature below 160 °C, self-heating behaviour does not need to be determined.
