Reference 2

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

Reference 3

Endpoint:

flammable gases

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a solid

Reference 4

Endpoint:

pyrophoric liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a solid

Reference 5

Endpoint:

pyrophoric solids

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 known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Endpoint:

self-heating substances / mixtures

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

Description of key information

The test item diammonium persulfate was determined to be not flammable. Additionally, no flammability in contact with water and no pyrophoric abilities were expected. Thus, the latter two studies were waived.

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

The test item diammonium persulfate was determined to be not flammable. (BZ = 1, no flame expansion)

Justification for classification or non-classification

Based on the results obtained from the flammability test (non flammable, Key study) and taking into account the provisions laid down in Regulation 1272/2008/EC (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182, diammonium persulfate was not considered a flammable solid.
