1 Scope
This Part of GB/T 9978 specifies the procedures to be followed for determining the fire resistance of non-loadbearing vertical separating elements when exposed to heating on one face. The test is neither appropriate for the evaluation of curtain walls (non-loadbearing external walls suspended from the ends of floor slabs) nor for walls containing doors or glazing.
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 document.
