Тезис

This part of ISO 834 specifies the procedures to be followed for determining the fire resistance of columns when

tested on their own.

Columns are normally tested with all sides fully exposed to heating. However, when in practice the exposure is

from fewer than four sides, appropriate exposure conditions have to be reproduced.

The application of this test to other untested forms of construction is acceptable when the construction complies

with the direct field of application as given in this part of ISO 834 or when subjected to an extended application

analysis in accordance with ISO/TR 12470. Since ISO/TR 12470 gives only general guidelines, specific extended

application analyses are to be performed only by persons expert in fire-resistant constructions.

General guidance on this test method is given in annex A.
