Administrative data
Link to relevant study record(s)
- Endpoint:
- explosiveness, other
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 July 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: “Go/No Go” screening test which is detailed in ASTM E1226-10, “Standard Test Method for Explosibility of Dust Clouds”
- Deviations:
- not specified
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- - Sample received: 23 June 2011
- Key result
- Parameter:
- other: Explosion Overpressure (bar)
- Value:
- 7
- Remarks on result:
- other: Go to further testing
- Key result
- Test series:
- other: St2 cladd dust
- Remarks:
- very energetic
- Method:
- other: ASTM E1226-10 - Standard Test Method for Explosibility of Dust Clouds
- Parameter:
- other: bar
- Remarks:
- m/sec
- Value:
- 206
- Remarks on result:
- other: Go to further testing
- Conclusions:
- The dust explosibility of the test item results indicate that the sample produced a KSt value of 206 bar m/sec, thus, classifying it as St2 class dust and is considered very energetic. The test item may present an explosion and deflagration hazard risk when dispersed and ignited in air.
Secondary explosions may also pose a risk once an initial explosion occurs with the presence of a combustible dust or powder in the area. The KSt and Pmax values are used in designing plant explosion relief and suppression/ containment systems. - Executive summary:
The dust explosibility of the test item results indicate that the sample produced a KStvalue of 206 bar m/sec, thus, classifying it as St2 class dust and is considered very energetic. The test item may present an explosion and deflagration hazard risk when dispersed and ignited in air.
Secondary explosions may also pose a risk once an initial explosion occurs with the presence of a combustible dust or powder in the area. The KStand Pmaxvalues are used in designing plant explosion relief and suppression/ containment systems.
