Foreword
GB/T 9978 "fire test method for building components" is expected to be divided into the following sections.
--- Part 1. General requirements;
--- Part 2. Fire test furnace calibration;
--- Part 3. Test methods and test data application notes;
--- Part 4. Bearing vertical separation member of the special requirements;
--- Part 5. load-bearing horizontal partition special requirements;
--- Part 6. Beam special requirements;
--- Part 7. special requirements of the column;
--- Part 8. Non-load-bearing vertical partition special requirements;
--- Part 9. Non-load-bearing ceiling components of the special requirements;
This section GB/T 9978 Part 5.
This part of the amendment uses ISO 834-5..2000 "fire test building components - Part 5. load-bearing horizontal partition member special
Seeking "(English version).
This section is based on ISO 834-5..2000 redrafted. Appendix A of the original ISO 834-5..2000 Appendix, Appendix B lists the headquarters
Sub-chapter number and ISO 834-5..2000 Chapter Article number control list.
Taking into account China's national conditions, the adoption of ISO 834-5..2000, made some changes in this section. The relevant technical differences have been incorporated into the text
And marked with a vertical single line in the margins of the terms of the articles they cover. These technical differences and their precursors are given in Appendix C.
Because of the list, for reference.
For ease of use, corresponding to ISO 834-5..2000, this section also made the following editorial changes.
--- "This part of ISO 834" was revised to "This part of GB/T 9978";
--- Use the decimal point "." Instead of as a decimal point comma ",";
--- Remove the foreword and foreword of the international standard.

Fire resistance test method for building components
Part 5. Particular requirements for load - bearing horizontal partition members
1 Scope
This section GB/T 9978 specifies the test method for determining the fire resistance of the load-bearing horizontal partition members whose surface is exposed to fire.
This section also applies to the horizontal load-bearing separation of such girders if the roof or floor elements are not supported by the girders and can not be tested
member. However, test data can not be transferred directly between the two specimen components.
When the structure of untested building components in line with the conditions of direct application scope given in this section has been carried out in accordance with the provisions of this section
Fire resistance test of the components of the fire resistance results can be applied to similar components of the building has not been tested.
