JJG (Light Industry) 61-2000 "Paper and Cardboard Burst Resistance Tester" standard mainly stipulates the verification, use and maintenance requirements of paper and Cardboard Burst Resistance Tester. It is suitable for paper bursting resistance testers with a range of not more than 1600kPa and Cardboard bursting resistance testers with a range of 6000kPa. The standard covers the principle, structure, calibration method and technical requirements of the instrument, including pressure indication Precision, hydraulic cylinder oil feeding speed error, film resilience resistance value, etc. The verification content includes Appearance inspection, pressure measurement system sealing, sample clamping force, chuck coaxiality, etc., to ensure reliable instrument performance and accurate measurement. When using, follow standard environmental conditions and verification cycle, generally no more than one year.
