The work

5、 of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmen

6、tal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the

7、 ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possi

8、bility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

11、re resistance tests Fire dampers for air distribution systems Part 1: Test method AMENDMENT 1 Page 14, 6.3 The amendment adds reference to new Annex A at the end of the first paragraph. 6.3 Thermal release mechanism The thermal release mechanism shall be included in the specimen construction. If the

12、re are alternative release mechanisms where these are in series with the basic thermal release and can be shown to not inhibit the basic release, then only the one thermal release mechanism is required to be tested (see Annex A). New Annex A The amendment adds new informative Annex A. Annex A (infor

13、mative) Alternative thermal mechanism A.1 The following procedure may be adopted by the sponsor with the consent of the testing laboratory to evaluate alternative thermal release mechanisms. A.1.1 Alternative thermal release mechanism(s) can be installed in series with the basic thermal release and

14、tested in accordance with this International Standard. It must be shown that the alternate release mechanism does not inhibit the basic release. A.1.2 The thermal release that is installed with the damper is randomly selected from five identical units. Three of the remaining release mechanisms shall

15、 be evaluated to the requirements in ISO 10294-4 to determine a threshold response time. The threshold shall be the average response time of the three links when tested to the requirements of ISO 10294-4. The response time is used to evaluate the comparative performance of other alternative thermal release mechanisms that are evaluated to the requirements of ISO 10294-4.
