Endpoint:

self-heating substances / mixtures

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

Reason / purpose for cross-reference:

data waiving: supporting information

Specific details on test material used for the study:

- Name of test material: PURACAL PP/USP (Calcium-L-Lactate 5-Hydrate Powder USP)
- Physical state: white crystalline solid
- Analytical purity: 99.9%
- Lot/batch No.: 1107003133
- Expiry date: 2016-07-26
- Storage condition of test material: 15-30 °C

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

Preliminary test:

The test item could not be ignited. Based on the results no main test was performed.

Interpretation of results:

GHS criteria not met

Conclusions:

Based on the preliminary test, calcium (S)-lactate is considered as 'not highly flammable'.

Executive summary:

In a GLP study conducted according to EU Method A.10, the preliminary screening test showed no propagation of combustion of the test substance along 200 mm length of the pile. In compliance with the test guidance, the main test was therefore not required. The test substance is considered as 'not highly flammable'.

Description of key information

Calcium (S)-lactate is a non-flammable substance.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The test item is not classified as a flammable solid, flammable gas, pyrophoric liquid, pyrophoric solid, self-heating substance or as substance which emits flammable gases in contact with water.

Justification for classification or non-classification

The test material is not flammable. No classification is required.
