Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 2 : determination of the emission rates of carbon monoxide (CO), carbon dioxide (CO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2) during arc welding, cutting and gouging
ISO 15011-2:2009 defines laboratory methods for measuring the emission rates of carbon monoxide (CO), carbon dioxide (CO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2) generated during arc welding, cutting and gouging, using a hood technique. The methodology is suitable for use with all open arc welding processes, cutting and gouging, but different designs of hood are used depending on the process and whether or not it can be conducted automatically.

<p>ISO 15011-2:2003 provides guidance on the determination of emission rates of gases generated by arc welding using a fume box technique. It describes the test principle, gives a possible fume box arrangement and considers methods for sampling and analysis.</p> <p>The following gases that can be produced during arc welding are covered:</p> <p>- carbon monoxide (CO);</p> <p>- carbon dioxide (CO<sub>2</sub>);</p> <p>- nitrogen oxide (NO);</p> <p>- nitrogen dioxide (NO<sub>2</sub>).</p> <p>The fume box described in this International Standard may also be used for the determination of organic gases produced in the arc welding of coated metals, e.g. primed, painted or plastic coated material.</p>

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
