ISO 18903:2002 specifies a method for determining the dimensional change of photographic films and papers caused by:
- variations in equilibrium moisture content due to change in the relative humidity (RH) of the atmosphere (humidity coefficient of expansion);
- change in temperature (thermal coefficient of expansion);
This International Standard is not suitable for determining the dimensional change of instant photographic film.
