While the corresponding International Standard requires tests to be performed in normal humidity, this Standard specifies the humidity required for power consumption tests to be (70 ± 5) % at an ambient temperature of 32 °C ± 0.5 °C or (55 ± 5)% at an ambient temperature of 16 °C ± 0.5 °C based on the household kitchen environment survey (annual average temperature and humidity of 90 researched cases) in Japan.
