Note on standard condition: "standard condition" referred to herein is dened as follows:
5 to 35
of temperature, 45 to 85% relative humidity, and 86 to 106kPa of air pressure.
When there are questions concerning measurement results:
In order to provide correlation data, the test shall be conducted under condition of 20
2
of temperature, 60 to 70% relative hu-
midity, and 86 to 106kPa of air pressure. Unless otherwise specied, all the tests are conducted under the "standard condition."
(Note 1)
measurement shall be made after 48
