Explosion prevention and protection in underground mines - Protective systems - Part 2: Passive water trough barriers

This standard specifies the requirements for concentrated and distributed passive water trough barriers, and quick-deploy water trough barriers.
This standard specifies the requirements and test methods for water troughs which are used as components of the "water trough barrier" protective system for underground coal mines.
This standard does not apply to active water trough barriers.

Explosionsschutz in untertägigen Bergwerken - Schutzsysteme - Teil 2: Passive Wassertrogsperren

Diese Norm legt die Anforderungen an konzentrierte und aufgeteilte passive Wassertrogsperren und Wassertrog-Schnellsperren fest.
Diese Norm legt auch die Anforderungen und Prüfverfahren für Wassertröge fest, die als Komponenten des Schutzsystems "Wassertrogsperre" im Steinkohlenbergbau unter Tage Verwendung finden.
Diese Norm gilt nicht für aktive Wassertrogsperren.

Protection contre l'explosion dans les mines souterraines - Systèmes de protection - Partie 2: Arrêts-barrages passifs à bacs à l'eau

La présente norme définit les exigences relatives aux arrêts-barrages à eau passifs concentrés, répartis et rapides.
La présente norme définit également les exigences et les méthodes d’essais applicables aux bacs à eau utilisés dans les arrêts-barrages à eau dans les mines de charbon souterraines.
La présente norme ne s'applique pas aux arrêts-barrages à eau actifs.
