GB/T 9978.9-2008Fire-resistance tests -- Elements of building construction -- Part 9: Specific requirements for non-loadbearing ceiling elements (English PDF)

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 is Part 9 GB/T 9978's.

The partial modification of the use of ISO 834-9:2003 "Fire resistance tests Part 9 building elements. a special non-load-bearing member to the partition level Seeking "(in English).

This section according to ISO 834-9:2003 redrafted. Appendix A of ISO 834-9:2003 original Appendix and Appendix B lists headquarters Sub-reg number and ISO 834-9:2003 reg control list numbered.

Taking into account China's national conditions, in the use of ISO 834-9:2003 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 834-9:2003, this section also made the following editorial changes.

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

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

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

This section in Appendix A, Appendix B and Appendix C are informative appendices.

1 Scope

GB/T 9978 in the lower part of this section provides test procedures for determining the non-load-bearing properties of the ceiling element fire by the fire, the ceiling member class Fire performance has not affected the upper portion of any building components. This section applies to non-load-bearing ceiling member, including self-supporting ceiling, Suspended ceiling and simply supported Ceiling.

When untested structural building elements eligible direct application of this section gives the provisions of this section have been made according to the provisions of Element fire Fire Test performance results can be applied to similar building components untested.

This section does not apply to horizontal fire separation member above the load-bearing member to protect its ceiling, the ceiling fire resistance class member You can press GB/T 9978.5 test.
