Foreword

GB/T 9978 "building components resistance test methods" is expected to be divided into several parts as follows.

--- Part 1. General requirements;

--- Part 2. fire resistance test furnace calibration;

--- Part 3. Test methods and test data application notes;

--- Part 4. load-bearing vertical partition member of the special requirements;

--- Part 5. horizontal load-bearing partition member of the special requirements;

--- Part 6. Particular requirements for the beam;

--- Part 7. Particular requirements for the column;

--- Part 8. Particular requirements for non-load-bearing vertical partition member;

--- Part 9. Particular requirements for non-load-bearing ceiling member;

This section GB/T 49978 Part of.

The partial modification of the use of ISO 834-4:2000 "Fire resistance tests for building elements - Part 4. load-bearing vertical partition member special to Seeking "(in English).

This section according to ISO 834-4:2000 redrafted. Appendix A of ISO 834-4:2000 original Appendix and Appendix B lists headquarters Sub-reg number and ISO 834-4:2000 reg control list numbered.

Taking into account China's national conditions, in the use of ISO 834-4:2000 when this part has made several modifications. About the technical differences have been incorporated into the text and identifies a single vertical line in which they are involved with the provisions margin. Given these technical differences and its prime in Appendix C Because the list for reference.

For ease of use, corresponding to ISO 834-4:2000, this section also made the following editorial changes.

--- "This part of ISO 834" was changed to "GB/T 9978 to the present section";

"." --- With a decimal point instead of a comma as the decimal point, "";

--- Remove the foreword and introduction of international standards.

This part of the Annex A, Annex B, Annex C is informative appendix.

1 Scope

This section GB/T 9978 specifies the fire resistance test method for testing load-bearing vertical partition member side when exposed to fire.

This section applies to the vertical load-bearing partition member of the fire resistance test; when the building structure member untested section gives a straight line with the Applications received when a predetermined condition, fire resistance test has been carried out according to provisions of this Part of building elements, the fire resistance test results can be applied without Similar building components.
