ISO 16260:2016 defines the internal bond strength as follows: “average potential energy expressed as J/m2 relative to the surface area required to delaminate a specimen under test conditions.” Further above, the standard describes the Scott Bond method as “a method for determining the internal bond strength […] but in this method the delamination force is applied very rapidly (abruptly) which is much higher than in other methods. This method can therefore be used primarily to assess the performance of a sheet under printing and processing conditions.”
