Equipment Overview: the use of a pendulum, tear samples and pointed tear strength. Paper tearing tester is dedicated equipment paper tear strength. Meet the criteria: performance parameters in line with ISO1974 "Paper - Determination of tearing resistance (Elmendorf love Lee Law" and GB455 relevant provisions of a "paper tearing assay" and other industry standard applications:?. Is the paper, research and Product Quality Supervision, Inspection and other industries and sectors ideal testing instrument technical parameters: 1. Model ZL-9010B 2. Measuring range a standard swing: (10-1000) mN, dividing the value of 10 mN b Qingbai: (10 -500) mN ,, dividing the value of 5 mN c heavy pendulum:. (100-8000) mN, dividing the value of 100 mN 3. instruments were equipped with standard pendulum, Qingbai, heavy pendulum 4 shows special orders according to user requirements. Value Accuracy (1) Indication error: within the range of 20% -80% in the measurement limit ± 1%, outside the range of ± 0.5% FS (2) Repeatability error: upper limit of the 20% -80 measurements % within the range of <1%, outside the range of <0.5% FS.
