JJG (Light Industry) 115-2000 "Carton Compression Testing Machine" specifies the verification and inspection requirements for carton compression testing machines with a maximum test force of not more than 50kN. The procedure is based on international standards such as ISO 2872:1985 and ISO 2874:1985, combining the technical requirements of JJG 157. The testing machine is used for corrugated carton compressire strength and stacking strength testing, mainly composed of force application system and measurement and control system. The procedure details the technical requirements such as Precision of force value, error of indication of deformation amount, Test speed error, etc., and specifies verification conditions, methods and cycles to ensure the accuracy and Reliability of the testing machine.
