EC Directive stipulates new labelling requirements

Since beginning of 2009, the European CLP Directive (Classification,Labelling andPackaging) is in force. This EC regulation is set up to harmonise the classification and labelling of substances and mixtures all over the world as well as standardise safety data sheets (one substance = one classification/labelling worldwide). For this reason, changes in the hazard pictograms as well as in the hazard and safety notes become necessary, which can also be found on products of Quarzwerke.


The new symbols should be in the shape of a square set at a point (diamond shape), and should have a black symbol on a white background with a red border.

Many of the previous hazard and safety notes, which indicate in a simple way the safe handling and use of hazardous substances, are still familiar from chemistry lessons at school. The R- and S-phrases are substituted by “H”- and “EUH” for hazard information (hazard statement) and “P” for safety information (precautionary statement). Furthermore, the two signal words “Danger” and “Warning” are introduced. Producers and importers have to classify and label their products according to the new regulation as of 1stof December 2010 and to notify the classification to the European Chemicals Agency (ECHA).

For Quarzwerke, all products with a high content of respirable crystalline silica (RCS) have to be labelled within given thresholds [RCS concentration between 1 % and 10% as Specific Target Organ Systemic Toxicant category 2 (STOT 2) and exceeding 10 % as Specific Target Organ Systemic Toxicant category 1 (STOT 1)].

This implies also that besides quartz flours additionally other products as for instance feldspar, kaolin or wollastonite flours with a higher RCS content require an adequate labelling. Especially for products for end-users, a communication to the customer has to be initiated in due time.

For the definition of the RCS content a new, universally applicable and scientifically verified measuring method has been developed (SWERF:SizeWeightedRespirableFraction). Our central laboratories in Frechen and Hirschau are intensively investigating the RCS content of all concerned products.

For the use of chemicals and auxiliaries no big changes are to be expected. The labelling gives reference to the physical, environmental and health related hazards.
