Introduction
Welding and allied processes produce airborne particles and gaseous by-products, which can be harmful to human
health. Knowledge of the quantity and composition of the airborne particles and gases emitted can be useful for
occupational hygienists in assessing workplace atmospheres and in determining appropriate control measures.
Emission rates cannot be used directly to assess the welder's exposure, but it is expected that processes,
consumables and welding parameters giving low emission rates will result in lower welder exposures than
processes with high emission rates used in the same working situation.
The laboratory procedure described in this standard can be used to determine the emission rate of gases
generated by arc welding and provides a method of sampling the gases for chemical analysis. The gases
generated and their emission rates depend upon the welding process, welding parameters, work piece surface,
coatings, etc.
In the context of this standard emission rate means the total amount of a substance per unit time that is produced
under defined process conditions, by different reactions in the system defined in this standard.
Gases encountered in arc welding are so numerous that it would be impracticable to cover them all in this standard.
The scope of this standard has therefore been limited to those gases, which are commonly generated during arc
welding.
It has been assumed in the drafting of this standard that the executions of its provisions, and the interpretation of
the results obtained, is entrusted to appropriately qualified and experienced people.
