This Korean Industrial Standard 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 loading heat test of fire-protection clad steel column shall comply with this Standard,
and when the non-loading heat test as needed it shall comply with Annex 2.
Remark 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 text or when subjected to an extended application analysis in accordance with ISO/TR 1270. 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 1.
