Hygiène et sécurité en soudage et techniques connexes — Équipements de captage et de filtration des fumées — Partie 4: Détermination du débit volumique minimal d’air des dispositifs de captage
| Published By | Publication Date | Number of Pages |
| ISO | 2020-02 | 18 |
Le présent document spécifie deux méthodes qui permettent de déterminer le débit volumique d'air minimal. Une méthode est applicable pour l'utilisation avec des dispositifs de captage, des buses et des fentes aspirantes ayant un rapport longueur de fente sur diamètre du tuyau inférieur ou égal à 8:1. L'autre méthode est applicable pour l'utilisation avec des torches aspirantes de soudage.
Ces méthodes ne s'applique aux tables aspirantes.
