Top suggestions for Adhesive strength—Determine the adhesive strength of Tape that is made from fabric by cutting a strip of the Tape 2.54 cm wide and approximately 15 cm long, and applying 12.90 sq cm, 2.54 cm by 5.08 cm, of one end of the strip to a clean plastic or glass surface by means of a rubber roller under a pressure of 850 g, passing the roller twice over the Tape at a rate of 30 cm per minute. Adjust the temperature of the plastic or glass surface and the Tape to 37°, and conduct the test immediately thereafter as directed under Tensile Strength á881ñ, using a pendulum-type testing machine, the pull being exerted parallel with the warp and the plastic or glass surface: the average of not less than 10 tests is not less than 18 kg. ka vidio |
