Abstract
The test method covers procedures for determining pressure spots and adhesion or anti-adhesion properties of organic coatings applied to coil coated or factory coated metal substrates prior to fabrication. The coated metal is cut into at least four and, recommended, six sheets of suitable size, which are then placed under a specified pressure and temperature for a specified period of time. After stopping heating and cooling the sample, the sample was checked for any signs of adhesion or blocking and blotching.
