Terminology explanation and practical application
Surface resistance: The ratio of the voltage applied between two electrodes to the current flowing on a certain surface of the test material. Mainly used for the evaluation of the conductive properties of optical functional films.
Actual case: When using a high resistance meter to directly measure the surface resistance of PET film, it is necessary to ensure that the test environment meets the requirements of GB/T2918-1998 standard (temperature 23±3℃, humidity 50±5%) to avoid external interference affecting the test results.
Background of Standard Formulation
With the widespread application of optical functional films in the optoelectronic field, especially the rapid development of polyethylene terephthalate (PET) films, it is urgent to formulate a unified surface resistance measurement method. This standard is proposed by the China Petroleum and Chemical Industry Federation and managed by the National Technical Committee for Standardization of Optical Functional Film Materials, ensuring its scientificity and authority.
Technology Evolution Analysis
From the measurement principle, the GB/T33398-2016 standard adopts the high resistance meter direct measurement method, generates the test voltage through a DC high voltage generator, and combines an analog/digital converter and a microprocessor to achieve accurate measurement. Compared with traditional resistance measurement technology, this method significantly improves the measurement accuracy and efficiency.
Implementation Suggestions
1. Before testing, ensure that the high resistance meter is preheated for 5 minutes and adjust the test environment to standard conditions as required. 2. The sample preparation should be a square film without visible defects, with a size of at least 10cm×10cm. 3. Avoid touching the sample surface with your hands during the operation to prevent static electricity from affecting the measurement results.
