The JJG (Light Industry) 61-2000 Paper and Cardboard Burst resistance tester verification specification aims to standardize the method of verification of paper and Cardboard Burst resistance testers to ensure their measurement accuracy. It is suitable for paper bursting resistance testers with a range of not more than 1600 kPa and Cardboard bursting resistance testers with a range of 6000 kPa. This procedure includes verification of environmental conditions, requirements for the use of standard equipment, and verification items such as pressure indication Precision, hydraulic cylinder oil feeding speed, sample holding force, etc. The standard specifies the Appearance, Function, Performance and Safety protection requirements of the equipment to ensure the Reliability and Stability of the instrument in actual use.
