Reference

Endpoint:

oxidising solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From October 20, 2015 to October 26, 2015

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

EU Method A.17 (Oxidising Properties (Solids))

Interpretation of results:

GHS criteria not met

Conclusions:

According to EU A.17 test method, CJ307 is not considered as an oxidizing substance. Therefore, CJ307 was not met GHS criteria.

Executive summary:

The oxidizing property of CJ307 was determined according to EC REGULATION No 440/2008 Annex A.17 Oxidizing Properties (Solids). The result of preliminary test showed that the combustibility did not sustain, so the full train test is necessary. In train test, the result showed that the piles of sample cellulose-mixtures containing 10 to 90 % weight did not ignited in 2 min. Therefore, CJ307 is not considered as an oxidizing substance.

Description of key information

CJ307 is not considered as an oxidizing substance (EC A.17).

 

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

The result of preliminary test showed that the combustibility did not sustain, so the full train test is necessary. In Train Test, the result showed that the piles of sample cellulose-mixtures containing 10 to 90 % weight did not ignited in 2 min. Therefore, CJ307 is not considered as an oxidizing substance.
