1 Scope
This standard specifies alterative fire heating curves and other procedures that may need to be adopted under special fire circumstances of the elements of building construction. The alternative fire heating curves include hydrocarbon (HC), external fire exposure, slow heating, electric fire and tunnel fire RABT-ZTV heating curves; the additional test procedures include (weight and spray water) impact test and measurement of radiation.
This standard is applicable to the elements or accessories of building construction which need to be subject to fire resistance test under special fire heating curve conditions and/or to be subject to other additional tests during fire resistance test.
Unless one of the alternative fire heating curves is specifically required, the standard temperature-time curve given in GB/T 9978.1 shall be used. Similarly, the (weight and spray water) impact test and measurement of radiation shall only be undertaken when they are specifically requested.
