14、 that the ratio between the volume of the test load and the inner volume of the transport unit is equal to (50 f 5) %. If not otherwise stated, the test medium shall be water. For the test load, a minimum number of catering containers - made of stainless steel - shall be used. The containers shall h
15、ave the same size and the test load shall be distributed equally. The catering containers filled with the test medium and their lids shall be preconditioned at a temperature of a) 2 OC higher than the initial reference temperature (see 6.3), with a maximum dispersion of 1 OC, for hot conditions; b)
16、2 OC lower than the initial reference temperature (see 6.3), with a maximum dispersion of 0,5 OC, for cold conditions and for deep frozen conditions. The measuring test points shall be located at the geometrical centre of the test load of each catering container. Immediately prior to the measurement
17、, the transport unit shail be closed. 6.3 Measurement The measuring points sha be located at the geometrid centre of the test load of each catering container.
