Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-10-10 to 2018-02-14
- 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)
- GLP compliance:
- no
- 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
- Remarks:
- The test item melted
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The flammability of the test item 5'-O-(4,4'-Dimethoxytrityl)thymidine was determined according to UN N.1. During the preliminary screening test, the substance could not be ignited with a flame and melted. Therefore, no main test was necessary.
- Executive summary:
The flammability of the test item 5'-O-(4,4'-Dimethoxytrityl)thymidine was determined according to UN N.1. During the preliminary screening test, the substance could not be ignited with a flame and melted. Therefore, no main test was necessary.
The test item is not a readily combustible solid in the sense of UN Manual of Tests and Criteria, Method N.1.
Reference
The test item could not be ignited with a flame. The test item melted. The main test was not necessary.

Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
