Dear Greg:
Fire Test of Cable Trays.
Z~immer Nuclear Power Station On June 6, 1979, I witnessed a fire test of cable trays at Portland Cement Association laboratories, Skokie Illinois.
The intent of the test was to verify the resistance to fire exposure achieved with three 1 in. layers of Kaowool wrapped around cable trays.
Testing was conducted of four sections of loaded cable trays in the PCA beam furnace, following the ASTM E119 fire test procedure.
The protected trays successfully resisted the effects of the ex-posure fire for a period of not less than 90 min.
At that time, one bottom tray right over the burners recorded a maximum Cemper-ature of about 400 F (TC #9 in tray #4 -- see enclosure), and electrical failure in some cables occurred at about the same time.
Temperatures in the other bottom tray were somewhat lawgr, pre-sumably because one end was not sealed, and reached 400 F (at TC 47) at 1 hr. 45 min., shortly after the test had been stopped.
The two upper trays reached temperatures not exceeding 250 F average at the end of 90 min.
Sincerely, 7

I FIRE TEST THERMOCOUPLE LOCATIONS 7
T For the drawing showing the recommended thermocouple locations for each tray in the fire tests to be performed at 1
Portland Cement Association, please note the following:
l 1.
Thermocouples 1,2,3,4,5,6,7,8 and 9 are to be attached to the cables on the bottom of the tray.
2.
Thermocouple 14 is to be attached to a cable on the top of the tray.
e 3.
Thermocouples 10 and 11 are to be placed behind the first inch and second inch of Kaowool wrap on the tray.
4.
Thermocouple 12 is to be attached to the metal tray itself.
5.
Thermocouples 13 and 15 are to be attached to the outer wrap of Kaowool.
6.
Thermocouple 16 is to be located inside the seal, between the lid and the tray, t
l 7.
Thermocouples 17 and 18 are to be attached to the unistrut supports.
l All four cable trays will have the same thermocouple locations.
