Key requirements include minimum capture velocity at the welding arc, filter leakage limits, and system monitoring protocols. The standard also addresses the testing and certification of extraction units, making it easier for welding coordinators to select compliant equipment.
For welding engineers, understanding EN ISO 15012 is essential when setting up workstations or auditing existing ventilation. It directly supports compliance with occupational exposure limits (OELs) for welding fumes, such as those from manganese and hexavalent chromium.
