JJG (Light Industry) 58.2-2000 "Horizontal Paper Tensile Testing Machine" standard applies to the verification and use of horizontal structure paper tensile testing machines with a maximum test force of not more than 1000N. The standard is based on the relevant technical content of ISO 1924-1:1933 and ISO 1924-2:1985, and combines the technical requirements of JJG 157-1995. The standard specifies in detail the appearance requirements of the testing machine, zero adjustment mechanism, clamping device, dynamic chuck positioning, operating performance Safety protection and verification conditions. The testing machine is used to test the physical indicators such as tensile strength, tensile strength and energy absorption of paper and Cardboard to ensure the Precision and Reliability of the instrument.
