This standard specifies the product classification, requirements, test methods, inspection rules and marks, Encasement, transportation and storage of paper and Cardboard tearmeters. The Elmendorf tearmeter is suitable for tearing strength testing of materials such as paper, Cardboard and Tobacco flakes, referred to as the tearmeter. At the same time, it is recommended to calibrate the tearmeter periodically. Miscellaneous documents are cited in the standard, including Encasement storage and transportation diagram signs, methods for determining tearing degrees of paper and Cardboard, signs, general technical conditions for Encasement of mechanical and electrical products, and general technical conditions for light industrial machinery. In terms of product classification, the tearing tester is mainly divided into specifications based on the maximum test force during tearing. For specific range series and applicable fields, please refer to Table 1 in the standard.
