The 2020 GA meeting which normally takes place in May was postponed to November 4th due to the global pandemic. The November 4th meeting which was virtual saw 20 attendees and lasted an hour as most of the GA mandated task/decisions were addressed by way of votes prior to the meeting. Chaired by Interim Chairman Dr Bernd Friede, the meeting though brief was effective with some key decisions taken as follows:
Some highlights:
- Executive Committee: A new Executive team was endorsed with the 2nd Vice-Chairman becoming the Chairman and Secretary General maintained to ensure continuity
- Non-EU letter of Access Fees: Letter of Access fees and administration fees for non-EU REACH-Like regulations per substance, per legal entity for non-MARA members was established
- Members involvement in Non-EU regulations: MARA members wishing to register substances in non-EU REACH-like regulations will only pay administration fees as they own the data generated by MARA
- Technical update: Three dossiers updated this year lead to a new classification for manganese based UVCB’s
- 2020 Workplan and budget were ratified in Q1, 2020 via round robin votes.

DETERMINATION OF WATER SOLUBILITY/ SiMn slag (Silicomanganese slag)/ Method A6/ GLP
The water solubility of the test material, expressed as the total amount of total metal dissolved, has been determined using the flask method, Method A6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
The results can be seen in the table below:
Metal dissolved | Concentration range (g/l) |
Magnesium | ≤6.83 x 10-4 |
Aluminium | ≤9.45 x 10-4 |
Silicon | ≤2.26 x 10-4 |
Potassium | ≤3.60 x 10-4 |
Calcium | ≤2.64 x 10-4 |
Manganese | ≤3.27 x 10-4 |
Barium | ≤2.13 x 10-4 |
