Foreword

This standard is modified in relation to "Fire-resistance Tests - Door and Shutter

Assemblies" (ISO 3008 2007) (English edition).

This standard is redrafted according to ISO 3008.2007.For the convenience of

comparison, the "Comparison List of Chapter and Article Numbers between ISO

5 in this edition);

--- the requirements of test specimen are modified, and the relevant clauses are

rearranged (Chapter 4 in 1987 edition and Chapter 6 in this edition);

--- "design of test specimen" is added (see Section 6.3);

--- "verification" is added (see Section 6.5);

--- the installation requirements of test specimen are modified and arranged as an

independent chapter (Section 4.4 in 1987 edition and Chapter 7 in this edition);

--- the conditioning requirements are changed to adjustment and arranged as an

independent chapter (Section 4.5 in 1987 edition and Chapter 8 in this edition);

--- "Application of Instrumentation" is added (the Chapter 6 in 1987 edition is

modified and changed to Chapter 9 in this edition);

--- the test procedures are modified (Chapter 5 in 1987 edition and Chapter 10 in

this edition);

--- the judgment conditions are modified (Chapter 7 in 1987 edition and Chapter 11

in this edition);

--- the requirements of test report content are modified (Chapter 8 in 1987 edition

and Chapter 12 in this edition);

--- "Field of Direct Application of Test Results" is added (see Chapter 13);

--- "Comparison List of Chapter and Article Numbers between ISO 3008.2007 and

This Standard" is added (see Appendix A);

--- "Technical Differences between this Standard and ISO 3008.2007 and Their

Reasons" is added (see Appendix B);

--- normative appendix "Conditioning Requirements for Supporting Constructions"

is added (see Appendix C);

--- informative appendix "Estimation of Radiant Heat Flux Using Measured Surface

Temperature and the Stefan-Boltzmann Law" is added (see Appendix D).

In this standard, Appendix C is normative while Appendixes A, B and D are

informative.

Fire Resistance Tests - Door and Shutter Assemblies

Caution. the attention of all persons concerned with managing and carrying out

this fire-resistance test is drawn to the fact that fire testing may be hazardous

and that there is a possibility that toxic and/or harmful smoke and gases may be

evolved during the test. Mechanical and operational hazards may also arise

during the construction of the test elements or structures, their test and

disposal of test residues. Therefore, an assessment of all potential hazards and

risks to health shall be made and safety precautions shall be identified and

provided. Appropriate training shall be given to relevant personnel. Laboratory

personnel shall ensure that they follow written safety instructions at all times.

1 Scope

This standard specifies the fire resistance test method for the door and shutter

assemblies installed at the opening of the vertical separating members, such as.

2 Normative References

The following normative documents contain provisions which, through reference in

this text, constitute provisions of this standard. For dated references, subsequent

amendments to (excluding amending errors in the text), or revisions of, any of these

publications do not apply.

3 Terms and Definitions

For the purposes of this standard, the terms and definitions specified in GB/T 5907

and GB/T 9978.1 as well as those listed below apply.

4 Test Equipment

Instrumentation of heat flux from the unexposed surface of test specimens shall

be made as described in Article 9.3.2.

5 Test Conditions

The temperature and pressure conditions in the test furnace shall meet the

requirements of GB/T 9978.1.

6 Test Specimen

The test specimen shall be manufactured according to the method specified in GB/T

7 Installation of Test Specimen

The fire resistance of the supporting construction shall not be lower than that of the

test specimen, and shall not be determined during the test of test specimen.

8 Conditioning of Test Specimen

Where some product standards require mechanical performance test before the start

of the fire resistance test, test shall be carried out by reference to the requirements of

corresponding product standard.

9 Application of Instrumentation

The measurement of heat-flux from the unexposed surface of specimens shall be

made by an instrument complying with the following specifications.

The measurement shall be taken at the following positions.
