This standard practice is used for the creasing of paper and other thin sheet materials to provide
reproducibly creased specimens for testing water vapor transmission. It is not applicable to paperboard.
This is a standard practice for static creasing; for kinetic creasing see TAPPI T 512 "Creasing of Flexible
Packaging Material Paper Specimens for Testing."
This procedure can be used with water vapor transmission tests TAPPI T 448 "Water vapor transmission
rate of sheet materials at standard temperature and humidity", TAPPI T 464 "Gravimetric determination of water vapor
transmission rate of sheet materials at high temperature and humidity," and TAPPI T 523 "Dynamic measurement of
water vapor transfer through sheet materials."
