Achtung! N.n.gepr.

Achtung - noch nicht vollständig geprüfter Stoff. (= Caution - Hazardous potential not completely determined)

According to article 8 of the Council Directive 67/548/EEC all compounds with not completely known properties, which are not to be classified according to § 5 Chemikaliengesetz, have to be labelled with the phrase given above. Additionally, all properties already known must be denoted as usual (symbol of hazard; R/S phrases).

Since according to § 5 Chemikaliengesetz a classification is only necessary when the production per year exceeds 100 kg (for scientific use and development only) or 10 kg, respectively, (all other purpose) practically all compounds prepared in the university with unknown hazardous potential may be labelled with this phrase. So in this case it is not necessary to examine the hazardous properties.
