This specification applies to repositionable coloured note paper with Pressure sensitive adhesive strips on the back of each sheet. Manual steel rollers are used for the manufacture of paper pads and cylindrical spindles are used for marking tests. The standard specifies a minimum number of papers for the pad, and the paper should be firmly gluing through Pressure sensitive adhesive. The performance of the paper, including writing mass, paper clearability, multiple lifts, fiber optic pulls, etc., needs to be tested. Note paper should be kept clean, free of dirt, holes or tears, and uniform in Color and shape with smooth edges. The specification provides detailed criteria for note paper, ensuring that its mass and performance meet requirements.
