The maximum of these average shall be <br />documented for each thermocouple location. <br />See attachment 6 Pass <br />9.2.17 <br />Thermocouples shall be secured to gypsum surfaces <br />by the use of staples placed over the insulated portion <br />of the wires. <br />See attachment 1 Pass <br /> <br />The thermocouple tip shall be depressed into the <br />gypsum so as to be flush with the gypsum surface at <br />the point of measurement and held in thermal contact <br />with the surface at that point by the use of pressure- <br />sensitive paper tape. <br />See attachment 1 Pass <br />9.2.18 <br />Heat flux shall be measured with the sensing element <br />of at least two water-cooled Schmidt- Boelter gauges <br />at the surface of each instrumented wall: <br />See attachment 7 Pass <br /> a) Both are collinear with the vertical thermocouple <br />array; See attachment 7 Pass <br /> <br />b) One is positioned at the elevation estimated to <br />receive the greatest heat flux due to the thermal <br />runaway of the initiating module; and <br />See attachment 7 Pass <br /> <br />c) One is positioned at the elevation estimated to <br />receive the greatest heat flux during potential <br />propagation of thermal runaway within the initiating <br />BESS unit. <br />See attachment 7 Pass <br />9.2.18.1 <br />Heat flux measurements on walls may be waived for <br />residential units that are tested with the cheesecloth <br />indicator of 9.2.22. <br />Non-residential units N/A <br />9.2.18.2 <br />With reference to 9.2.18, if b) and c) are deemed to be <br />at the same location, only one gauge may be installed <br />on the wall for the measurement. <br />Non-residential units N/A
