Scope
This standard specifies two methods for determining the color fastness of dyed paper and cardboard in contact with food.
Method A of this standard is suitable for determining the color fastness of dyed paper and cardboard in contact with food for a long time (contact time ≥ 24 h) (e.g., food packaging paper), and Method B is suitable for determining the color fastness of dyed paper and cardboard in contact with food for a short time (contact time < 24 h) (e.g., napkins, kitchen paper).
