JJG (light industry) 49-2000 "Cardboard compressive strength tester" standard, suitable for the verification and use of Cardboard compressive strength tester with a maximum test force of not more than 3000N. This procedure is based on ISO3035:1982, ISO3037:1987 and ISO7263:1985 and other international standards, combined with the technical requirements of JJG157-1995. Cardboard compressive strength tester is used to measure the ring compressive strength and edge compressive strength of Cardboard, etc., using the method of gradually increasing the pressure until the sample is destroyed. The standard specifies the force value Precision, Test speed error, operating performance and Safety protection requirements of the tester, and details the verification environmental conditions and methods of verification to ensure the Reliability and accuracy of the instrument performance.
