Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14 September 2017 – 04 January 2018
- 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)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- 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
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- During the preliminary screening, the test item melted to form small, spherical particles. No ignition or propagation was observed. It was concluded that no further testing is required. Dilithium tetraborate can be considered as non-flammable.
- Executive summary:
Following the UN method Test N.1, a preliminary screening test was conducted initially. During the preliminary screening, the test item melted to form small, spherical particles. No ignition or propagation was observed. It was concluded that no further testing is required. Dilithium tetraborate can be considered as non-flammable.
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14 September 2017 – 04 January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.12 (Flammability (Contact with Water))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Test procedure:
- step 1
- step 2
- step 3
- Max. rate of gas release:
- 0 L/kg h
- Identity of evolved gas:
- not applicable as no gas evolved
- Remarks on result:
- no reaction with water observed
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- No gas generation or spontaneous ignitions were observed when a small quantity of the sample was placed in contact with water. Dilithium tetraborate is therefore not classified as Division 4.3.
- Executive summary:
UN Test N.5 was used to test a sample of dilithium tetraborate to determine if it generates flammable gas when in contact with water.
No gas generation or spontaneous ignitions were observed when a small quantity of the sample was placed in contact with water. Dilithium tetraborate is therefore not classified as Division 4.3.
- Endpoint:
- pyrophoric solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14 September 2017 – 04 January 2018
- 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.2 (Test method for pyrophoric solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Test procedure:
- ignition time on contact with air
- Remarks on result:
- no ignition on contact with air (not further specified)
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- No ignitions were observed during the six tests. The sample is therefore exempt from classification as a pyrophoric solid of UN Class 4, Division 4.2, Packing Group I.
- Executive summary:
A sample of dilithium tetraborate was tested according to UN Test method N.2 to determine if the substance was a pyrophoric solid.
No ignitions were observed during the six tests. The sample is therefore exempt from classification as a pyrophoric solid of UN Class 4, Division 4.2, Packing Group I.

Description of key information
A preliminary screening test showed that the sample melted to form small, spherical particles. No ignition or propagation was observed. It was concluded that no further testing is required.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
A preliminary screening was conducted which showed no ignition or propagation was observed. It was concluded that no further testing was required. Dilithium tetraborate can be considered as non-flammable and does not require classification.
