Health and safety in welding and allied processes. Equipment for capture and separation of welding fume - Determination of the minimum air volume flow rate of capture devices Ingestion-build-79769 It does not cover safety

It does not cover safety issues nor does it conflict with ITU-T efforts concerning the protection of telecommunications equipment [2]2

specific adjustment factors for calculation of characteristic values are given in EN 384

The smoke density test enables the calculation of the amount of smoke given off by a material that is burning or smouldering

methods of testing and acceptance levels are not covered in this standard as they depend on the service conditions of the fabrication

This will lead to better value for money for local authorities as the repairs will be more durable

Health and safety in welding and allied processes. Equipment for capture and separation of welding fume - Determination of the minimum air volume flow rate of capture devices Ingestion-build-79769 It does not cover safety1 Scope This document specifies two methods for establishing the minimum air volume flow rate. One method is dedicated for use with captor hoods, nozzles and slot nozzles with a ratio of slot length to hose diameter of 8: 1 or less. The other method is dedicated for use with on gun extraction devices. These methods are not applicable to down draught tables.
