- E.3.3 If the facestock breaks during the adhesion test, apply a self-adhesive tape to the surface to reinforce it. The tape shall be low stretch, e.g. polyester, and between 0.04 mm and 0.021 mm thick.
- E.3.4 The average adhesion value for each test specimen shall be in accordance with the requirements for adhesion specified in 5.1, 5.2 and 5.3. The results shall be expressed for each test specimen and shall be given in Newtons per 25 mm.
- E.3.5 If the facestock delaminates, or the reinforcing tape peels from the label surface on adhesion testing, these values shall be recorded in accordance with E.3.3 and used in E.3.4.
