EFFECT OF MOIST HEAT ON PROPERTIES OF PAPER AND BOARD

• This method specifies the procedure for humidified heat treatment of paper or board and the general procedure for testing the heat-treated materials.
• This method now is practically identical to ASTM D 4714 “Standard Test Method for Determination of Moist Heat (50% Relative Humidity and 90ºC) on Properties of Paper and Board.”
• This method was originally for 25% relative humidity.

It Provides information on:

• Test methods
• Sampling
• Test specimens
• Conditioning for subsequent testing
• Treatment of data
• Statistical significance
