GB/T 2679.5-1995 《Paper and board－Determination of folding endurance (MIT tester)》 Related products

GB/T 2679.5-1995 "Determination of the folding resistance of paper and Cardboard (MIT folding tester method) " standard specifies the use of MIT Folding tester to measure the folding resistance of paper and Cardboard. The standard is equivalent to the relevant part of the international standard ISO 5626-1978. It applies to paper or Cardboard with a thickness of less than 1.00 mm. The standard describes the requirements of the tester in detail, including the technical parameters such as the chuck with adjustable spring tension, the folding angle, the folding speed, and specifies the sampling and processing methods of the sample, the test procedure, and the precision requirements of the test results. The standard needs to be strictly followed during the testing process to ensure the accuracy and Repeatability of the measurement results.
