N2 - Die seit 2003 gültige Nitroxnorm EN13949 ist in Taucherkreisen ein viel diskutiertes Thema. Vor allem das für Nitrox und Sauerstoff normierte Ventil nach EN144-3 mit dem M26x2 Anschluss sorgt in den letzten Monaten für rote Köpfe. Auch weil die 5jährige Übergangsfrist dafür Ende Juni 2008 in Deutschland abgelaufen ist. Mehrere Autoren aus dem In- und Ausland, welche auf EU-Niveau Experten in Tauchernormen sind, konnte DiveInside für diesen Beitrag gewinnen. Die Autoren Ciscato, Szypkowski und Aris, gehören dem CEN/TC 79/SC 7 (diving apparatus Normenkomitee) an und sind aktiv an der Erstellung und Revision von Tauchgerätenormen und Ventilnormen beteiligt.

T1 - Another dangerous practice in the SCUBA diving community N2 - The widely held incorrect belief in the self-contained underwater breathing apparatus (SCUBA) diving community, that oxygen-enriched gas mixtures, so-called NITROX, with an oxygen content of up to 40 vol. % can be considered as regular air, has already been refuted in many papers. Now, another dangerous practice has drawn the attention. In a market study, more than 60 representative SCUBA cylinder valves were examined. Sales offices claim that all of those valves can be used for oxygen-enriched gas mixtures. The fact is that some of these cylinder valves are for air use only. By exchanging the nonmetallic materials and applying additional cleaning procedures, these air valves become so-called “oxygen clean.” Then, the valves are on sale for oxygen-enriched service. This procedure is dangerous because the labeling pretends a pseudo-safety. All of the 60 SCUBA cylinder valves were tested applying the standardized oxygen pressure surge tester at BAM. As suspected, many of the cylinder valves are not burn-out safe. In addition, different test results were received for actual new valves, for so-called new but temporarily stored valves, and for used valves. This paper reveals another dangerous practice and wants to alert the SCUBA diving community.
