Annotation of standard text ÖNORM EN ISO 11986 :

Dieses Dokument legt die allgemeine Vorgehensweise für die Auswahl von Prüfverfahren, die Vorbereitung von Prüfmustern und die Durchführung von Prüfungen der Aufnahme und Wiederfreisetzung von Konservierungsmitteln durch Kontaktlinsen fest. Die Prüfung auf Aufnahme und Wiederfreisetzung ist nicht als Routineprüfung für die Herstellung von Kontaktlinsen oder Kontaktlinsenpflegemittel gedacht, noch sollen die Prüfergebnisse in irgendeiner Weise zur Spezifikation von Endprodukten dienen. Solche Prüfungen werden bei der Entwicklung neuer Kontaktlinsenmaterialien und/oder Kontaktlinsenpflegemittel durchgeführt. ANMERKUNG 1 Aufgrund der offensichtlichen Schwierigkeit bei der Reproduzierbarkeit der Beschichtung von Kontaktlinsen mit mineralischen und organischen Ablagerungen, die beim Tragen der Linsen auftreten, sind diese Verfahren nur auf neue und unbenutzte Kontaktlinsen anwendbar. ANMERKUNG 2 Der Abbau von Konservierungsmitteln durch eine Kontaktlinse in dem begrenzten Volumen eines Kontaktlinsenbehälters könnte die Desinfektionsleistung beeinträchtigen. In diesem Dokument wird die Desinfektionsleistung nicht gemessen
