The specimens shall be positioned in a single layer within the centre portion of the cable tra
5、y, with one end of each specimen not more than 100 mm above the bottom end of the tray. Each specimen or group of specimens shall be separately attached to the rungs of the tray, using metal wire ties of suitable size, such that the specimens remain in position throughout the test. There shall be on
6、e attachment at 0.2 m from the bottom end of the tray and other attachments spaced no more than 0.45 m apart.6.16.10.2 The individual specimens shall be attached to the cable tray with spacings one-half the diameter of the conduit or tubing, except that the spacings shall not exceed 15 mm. The tray

The upper portion of the tray shall be firmly fixed in position.6.16.11.2 The burner shall be ignited and gas flows shall be adjusted to the values in Clause 6.16.9, with the burner positioned
9、 away from the specimen. The burner, at an angle of 20 from the horizontal, shall then be positioned in front of the tray and 75 5 mm from the nearest conduit or tubing surface.

Wher
14、e the surface of the conduit or tubing changes from a resilient surface to a brittle (crumbling) surface, the limit of char has been determined.6.16.12.3 The conduit or tubing damage (char) shall be recorded to the nearest 50 mm.6.16.13 CriterionThe length of the char after completion of the test sh

The conduit or tubing shall be considered FT6 if it meets the requirements specified in Clause 6.17.1.3.6.17.1.2 The test specimens shal
16、l be arranged in accordance with Clause 6.17.2.6.17.1.3 Using the test apparatus and method described in ULS S102.4 or NFPA 262, the conduit or tubing shall be considered acceptable if it meets each of the following conditions:a) The maximum flame-propagation distance shall not be greater than 1.5 m
17、 beyond the initial 1.4 m of test flame.b) The peak optical density of the smoke produced shall not exceed 0.50 (32% light transmission).(c) The average optical density of the smoke produced shall be 0.15 or less.(Replaces p. 14, January 2005)14Update No. 2C22.2 No. 211.0-03September 2006Note: Gener
