5.1 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. Relative humidity is also an important operating variable for the calibration of many species of measuring instruments. Hand held test measures require a 30 s (± 5 s) pour followed by a 10 s drain, with the measure held at a 10 degree to 15 degree angle from vertical, touching off any adhering drop from the neck, during calibration and use. Provers are emptied by gravity drain, followed by a 30 s final drain after the cessation of flow.
