Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Comment

Run 1

Initial points as lower temperatures did not show linearity with measurements at higher temperature. It was suspected that sufficient time had not been allowed for equilibration. Therefore, they have been excluded from the results in the table above.

Excluded points:         20.1 °C, 0.0154 mbar (1.5 Pa)

                                   28.7 °C, 0.0634 mbar (6.3 Pa)

 

Run 2

The lower temperatures were allowed to reach equilibrium for a longer period of time. They show agreement with Run 1 for linearity.

Conclusions:
The results of testing completed on NeximidTM 300 (PETA): 7.0 Pa @ 20°C (mean of 2 runs).
The results of testing are highly dependent on the composition and physical nature of the sample. In dust explosion testing, for example, the particle size distribution, moisture content, particle shape and preparation method can all markedly affect results. For this reason, any change in manufacturing / handling procedures or composition should be accompanied by a review of the relevant data.
Executive summary:

The test was conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A4.
