      JJG (Light Industry) 52-2000 "Paper and Cardboard asperity tester" standard specifies the method of verification for instruments measuring paper and Cardboard asperity by air leakage method. The standard applies to Bentsen Roughness Gauges with a Flow rate range of 5mL to 3000mL, including first verification, follow-up verification and inspection in use. The standard covers the technical requirements and methods of verification of the instrument's Measurement performance, system sealing, compressor, airflow buffer, Glass plate, gas line connection pipe, asperity probe and Porosity probe to ensure measurement accuracy and instrument Reliability. The standard also specifies the verification cycle and the issuance of certificates of conformity.
