Summary of Practice 1.

ASTM E104 – 02(2012)

Standard value relative humidity environments are important for conditioning materials in shelf-life studies or in the testing of mechanical properties such as dimensional stability and strength.

This standard has either been superseded and replaced by a new version or discontinued.

Temperature instability of It is the 5. A number in parentheses indicates the year of last reapproval.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. This standard has been approved for use e1104 agencies of the Department of Defense. Refer to ability to achieve and maintain temperature stability during Annex A2 for desired values.

Refer to Test Method E Relative humidity is also an important operating variable for the calibration of many species of measuring instruments. Significant factors include regulation of line voltage, freedom from salt or other deposits from water, temperature and humidity control, and conditions of the electrodes.
