Foreword
This standard ISO 6944-1.2008 "fire separation - structural member - ventilation ducts" (in English) of the degree of non-conformity
Equivalent.
This standard replaces GB 17428-1998 "fire resistance test method of ventilation ducts."
This standard and GB 17428-1998 more significant changes are as follows.
--- Increase the "warning" content, suggesting that the user of this standard should be noted that matters (Excerpts of the "scope" before);
--- Modify the scope of a chapter, to further clarify the application of the criteria objects (Chapter 1, 1998 edition and this edition);
--- Modify the normative references (1998 edition and the edition Chapter 2);
--- Increased terms and definitions (see Chapter 3);
--- Modify the requirements of the test device (5th edition 1998, chapter 4 of this edition);
--- Modify the test conditions (1998 Edition Chapter 4, Chapter 5 edition);
--- Revised requirements for specimen (1998 Edition Chapter 6, Section 6 edition);
--- Increasing the installation requirements of the specimen (see Chapter 7);
--- Increased specimen conservation requirements (see Chapter 8);
--- Increased equipment requirements (see Chapter 9);
--- Modified test procedure (1998 Edition Chapter 7, Chapter 10 edition);
--- The observation, measurement, recording and incorporated into the revised test procedure (1998 Edition Chapter 8, edition Chapter 10);
--- Modify the determination criterion condition, and its contents have been modified (1998 Edition Chapter 9, edition Chapter 11);
--- Increasing the test results are expressed (see Chapter 12);
--- Modify the content of the test report (1998 edition Chapter 10, edition Chapter 13);
--- Increasing the direct application of test results (see Chapter 14).

Ventilation ducts resistance test methods
Warning.
Organizations and all those involved in this test should be noted that the fire resistance test can be dangerous. It is possible to produce in the fire resistance test in the process of
Toxic and/or harmful fumes and smoke. After the specimen installation, test procedures and test cleanup process residues, or it may appear dangerous machinery
Harm and dangerous operation.
After the fire resistance test before dismantling pipes, pipe should be completely cooled reach combustible residue without the possibility of resurgence.
Deal with all potential hazards and assess the health risks and make safety notice. It should enact rules to enter the relevant personnel
Line the necessary training to ensure that the laboratory staff by the rules and operations.
1 Scope
This standard specifies the level of ventilation ducts fire resistance test methods under standard fire conditions used to test the ventilation pipe to withstand external fire
(Pipeline A) and an internal fire (duct B) fire resistance effect when. Fire Test vertical duct may refer to this standard.
This standard does not apply to.
a) fire resistance depends on the ceiling fire resistance of the pipeline;
Pipe b) with access door, unless the access door into the pipe tested together;
c) both sides or three sides of the pipeline;
d) exhaust pipes;
e) to the wall or floor attachment hanging fixture.
