Test Simulator ( s ). A test simulator has comparable thermal characteristics with those of the great majority of foods , which typically contain 80% to 90% water , fibrous material , and salt . However , the simulator will not necessar – ily have exactly the same temperatures because different actual food products themselves will balance out at different temperatures in an identical environment due to differences in packaging , shape , conductivity , and related factors . These testsimulators are used in the test procedure as a standard measuring device , which can be duplicated in any laboratory . The simulator shall be a plastic container ( such as polyethyl – ene ) of at least473mL(1 US liquid pint ) volume , with alid conforming to the dimensions shown in Figure 3. The con – tainer shall be filled with any natural or artificial sponge material that is saturated with aheat transfer solution consist – ing of a 50/50±2% mixture ( by volume ) of propylene glycol and distilled water .
The temperature shall be measured within the simulator at the volumetric center point when the simulator height is between 50 and 70 mm (2 and 23/4 in .). If the simulator is more than 70 mm (23/4in.) high , the temperature sensor shall be located not less than 25 mm (1 in .) normore than 35mm(13/8in.) from the surface that is important in relation to the location of the simulator ( such as a surface subjected to radiant heat ). The temperature sensor shall be positioned at this measuring point either by routing it through one of the sides of the simulator and into the sponge material ( Method 1 in Figure 3b) or by routing it through the top , down one of the sides , and then into the sponge material ( Method 2 in Figure 3b).
There shall be a test simulator located in the display or storage area in the location that has the warmest temperature ( based on testing , prior experience , or judgment ).
filler material:
material consisting of water , or of a 50/50 mixture (±2%) of distilled water and propylene glycol , or wood blocks with an overall density not less than 480 kg / m (301b/ ft ); used for filling the refrigerator spaces not occupied by test simulators .
filler package:
a container with filler material that closely approximates food product characteristics ; used to fill the spaces between test simulators for product mass .
