General Information

Not classified
Implementation:
EU
Remarks:
In the case of cristobalite, although there is no harmonised EU classification for this substance under the former European Dangerous Substances Directive, it has been the practice for many years to self classify and label cristobalite flours as harmful with the label Xn and the risk phrases R48/20. Harmful: danger of serious damage to health by prolonged exposure through inhalation.
The CLP Article 8.6 specifies that “Tests that are carried out for the purposes of this Regulation shall be carried out on the substance or mixture in the form (s) or physical state(s) in which the substance or mixture is placed on the market and in which it can be reasonably expected to be used". In addition the ECHA Guidance to the CLP Regulation published on 13 July 2009 mentions that “for human health different forms (e.g. particle sizes, coating) or physical states may result in different hazardous properties of a substance or mixture in use” and therefore they may be classified differently. It is therefore justifiable to consider cristobalite in its respirable form for the purpose of classification.
It is considered to classify respirable cristobalite as STOT RE 1 for the silicosis hazard.
Consequently, mixtures and substances containing cristobalite in the form of an identified individual constituent, shall be classified according to CLP as:
STOT RE 1: if the cristobalite respirable fraction is equal to, or greater than 10%;
STOT RE 2: if the cristobalite respirable fraction is between 1 and 10%.
In the case the cristobalite respirable fraction in mixtures and substances is below 1%, no classification is required.
As kieselguhr soda ash flux calcined comes in a variety of different grades/forms containing variable amount of cristobalite respirable, each grade will have to be classified accordingly as described above.
