GB/T37977.23-2019 is a part of the electrostatic standard, which is dedicated to testing the resistance and resistivity of anti-static solid flat materials. It clearly defines the scope of applicable materials, explains the testing principle, and specifies the preparation and operation procedures of instruments and equipment, samples. Operating according to this standard, the material resistance and resistivity data can be accurately obtained, providing a key basis for the mass evaluation of anti-static solid flat materials, and the rational selection of electrostatic sensitive fields such as electronics and medical care. It helps to ensure the stable operation of equipment and personnel safety in relevant places.
