<p>This part of ISO 834 specifies the procedures to be followed for determining the fire resistance of columns when</p>
<p>tested on their own.</p>
<p>Columns are normally tested with all sides fully exposed to heating. However, when in practice the exposure is</p>
<p>from fewer than four sides, appropriate exposure conditions have to be reproduced.</p>
<p>The application of this test to other untested forms of construction is acceptable when the construction complies</p>
<p>with the direct field of application as given in this part of ISO 834 or when subjected to an extended application</p>
<p>analysis in accordance with ISO/TR 12470. Since ISO/TR 12470 gives only general guidelines, specific extended</p>
<p>application analyses are to be performed only by persons expert in fire-resistant constructions.</p>
