The temperature may:
not fall below 263 °K (-10 °C), or exceed 269 °K (-4 °C)
for more than three consecutive minutes.
3.1.2. The test cell temperature monitored during testing must be measured at the output of the cooling fan (section 5.2.1 of this Annex). The ambient temperature reported must be an arithmetic average of the test cell temperatures measured at constant intervals no more than one minute apart. U.K.
