CIS 90-1420 Water-soluble chromates in cement [Norway]
Vannløselige kromater i sement [en noruego]
This directive (effective 1 July 1988), stipulating a reduction of water-soluble chrome salts in cement, was issued because of the risks for chrome allergic eczema associated with the handling of unhardened cement. It applies to the production, importation and use of cement and unhardened cement products containing water-soluble chromates. In the directive the maximum chromate content of water-soluble chromates is set to 2mg per kg dry cement. Producers and importers of cement containing more than this amount must reduce chromate content to below 2mg/kg before they can use the cement.
