- Conclusions:
- Ferbam belongs to combustion class 4 (glowing without sparks or slow decomposition without flame) .
When a glowing Pt-wire of approximately 1000°C or a flame of a gas burner is applied, ignition with flame and smouldering of the whole powder layer is observed (combustion class 4). The burning rate is approximately 3 cm/5min.
The smoulder temperature or minimum layer ignition temperature (MLIT) of Ferbam is 190°C for a layer with a thickness of 15 mm.
The following observations were made at a temperature of 190°C:
• Glowing or smouldering can be observed.
• The maximum temperature in the dust layer (> 450°C) is higher than the plate temperature (190°C).
• The fumes that are produced could be ignited by means of an external ignition source (gas flame). - Executive summary:
The flammability test for Ferbam was conducted according to DIN VDI 2263 Blatt 1, 1.2.5 and to EN 50281 -2 -1.
When a glowing Pt-wire of approximately 1000°C or a flame of a gas burner is applied, ignition with flame and smouldering of the whole powder layer is observed (combustion class 4). The burning rate is approximately 3 cm/5min.
The smoulder temperature or minimum layer ignition temperature (MLIT) of Ferbam is 190°C for a layer with a thickness of 15 mm.

Reference
The sample was tested as received. It was not dried, milled or sieved.
The particle size distribution of the original sample was determined by means of a laser diffraction analysis. The median size (d50) of the original sample is 186 μm.
The moisture content of the powder was measured by means of a halogen moisture balance (temperature = 105°C, stop criterion = 2 digits/60s, sensitivity = 1 mg, initial sample = 1.5 g, resolution moisture content = 0.1%).
Remark: volatile components which are liberated at or below the set temperature of the moisture balance are included in the moisture content.
The moisture content of the sample was 1.8 %.
Burning behaviour (combustion class)
Test at room temperature (20°C)
The sample Ferbam 76WG “original fraction” belongs to combustion class 4 (glowing without sparks or slow decomposition without flame) .
When a glowing Pt-wire of approximately 1000°C or a flame of a gas burner is applied, ignition with flame and smouldering of the whole powder layer is observed (combustion class 4). The burning rate is approximately 3 cm/5min.
Smoulder temperature – 15 mm layer – Ferbam (< 200 μm)
The smoulder temperature or minimum layer ignition temperature (MLIT) of Ferbam is 190°C for a layer with a thickness of 15 mm. The results of the tests are given in the following table:
surface temperature (° C) | test result (max. temperature) | time to ignition or to reach the highest layer value of temperature without ignition (min) |
300 | Ignition (512 °C) | 21 |
260 | Ignition (510 °C) | 40 |
200 | Ignition (> 450 °C) | 120 |
190 | Ignition (> 405 °C) | 337 |
180 | No ignition (158 °C) | 52 |
180 | No ignition (160 °C) | 44 |
180 | No ignition (160 °C) | 73 |
The following observations were made at a temperature of 190°C:
• Glowing or smouldering can be observed.
• The maximum temperature in the dust layer (> 450°C) is higher than the plate temperature (190°C).
• The fumes that are produced could be ignited by means of an external ignition source (gas flame).
The dust layer consisted of 57.7 g of sample. The ambient temperature was 20 ºC.
Description of key information

When a glowing Pt-wire of approximately 1000°C or a flame of a gas burner is applied, ignition with flame and smouldering of the whole powder layer is observed (combustion class 4). The burning rate is approximately 3 cm/5min.
The smoulder temperature or minimum layer ignition temperature (MLIT) of Ferbam is 190°C for a layer with a thickness of 15 mm.
The following observations were made at a temperature of 190°C:
• Glowing or smouldering can be observed.
• The maximum temperature in the dust layer (> 450°C) is higher than the plate temperature (190°C).
• The fumes that are produced could be ignited by means of an external ignition source (gas flame).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
Based on the EU-GHS-criteria the substance is not flammable because burning rate is with approximately 5cm/5min > than limitvalue of 2mm/s stated in EU-GHS-regulation.
