Kiln drying of timber sometimes makes use of air at well above 100 °C and at very high humidities. The psychometric charts of Carrier and Mollier do not normally accommodate such air states and so they are not useful. Charts are given herein which use the axes ln r and ln ps where r is the relative humidity and ps is the pressure of water vapour at saturation.
According to the JESD22-A110 standard, THB and BHAST subject a device to high temperature and high humidity conditions while under a voltage bias with the goal of accelerating corrosion within the device. THB and BHAST serve the same purpose, but BHAST conditions and testing procedures enable the reliability team to test much faster than THB.

Jan 03, 2019· The CSS of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large an angle causes boiling in the crushing chamber; this is where the jaw plates cannot grip onto the rock and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine is set tighter.
