Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Name of the test material (as cited in study report): Tellurium diethyldithiocarbamate
- Batch No.: 60700109
- Expiration date of the lot/batch: 10-07-2018
- Purity: 99.19% (HPLC)
- Appearance: Light orange to yellow powder

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
The test item was stored in a tightly closed vessel at room temperature (15.8 – 21.5 °C) under dry conditions in the dark.

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

Since ignition did not occur within two minutes of the preliminary test, the test item was classified as not highly flammable. No observations were made which might cause doubts concerning the validity of the study outcome.

No determination of burning rate was necessary. Therefore, the determination of Burning Rate was not carried out.

Interpretation of results:

GHS criteria not met

Description of key information

No ignition was observed throughout the course of the test. The test item Tellurium diethyldithiocarbamate should be considered as not highly flammable. No observations were made which might cause doubts concerning the validity of the study outcome. The substance does not react with water to emit flammable gases. Furthermore, the substance has no pyrophoric or self-heating properties.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on the available information, classification on flammability is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
