Reference
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

The test item 4,4’-Dimethoxytrityl chloride could not be ignited with a flame in the preliminary burning phase and melted. The performance of the main test was not necessary as the test item is not a readily combustible solid.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The flammability of the test item 4,4’-Dimethoxytrityl chloride 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 4,4’-Dimethoxytrityl chloride 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 and is not a flammable solid according to chapter 2.7 of the GHS (CLP) regulations.

Description of key information
