GB/T3781.9-93 Isocyclic Carbon Black Resistance Measurement
Isocyclic carbon black is a odor-free, odourless coal-derived thermal black that is commonly used in rubber, plastics, inks and other industrial processes. This black absorbs ultraviolet light and improves surface colour, which makes it an essential component of many different products. GB/T3781.9-93 is a set of standards used to measure the resistance of isocyclic carbon black to electrical current. The standard specifies the voltage and current range that must be used and the accuracy of the results.
The electrical resistance of isocyclic carbon black must be determined in order to assess the performance of the material in various applications. Electrical resistance is the ratio of voltage to current in an electrical circuit. Isocyclic carbon black is particularly sensitive to electrical current, and its resistance must be precisely measured in order to obtain accurate results. GB/T3781.9-93 outlines the test procedure and accuracy required in order to accurately measure the electrical resistance of isocyclic carbon black.
In order to measure the electrical resistance of isocyclic carbon black, a specialized instrument called an electronic voltmeter is used. The instrument is used to measure the voltage and current between two points in an AC current, and the results are then reported as resistance. The tests must be conducted at room temperature, and the results must be recorded for at least 2 minutes in order to ensure accuracy.
GB/T3781.9-93 also specifies that a specified voltage and current range must be used when measuring the electrical resistance. The voltage and current range must be set between 0.5 and 200 volts, and the current must not exceed 2mA in order to prevent potential damage to the instrument or the isocyclic carbon black sample. The results must meet a accuracy level of 0.03%, and any readings that fall outside of this range must be re-measured.
Finally, GB/T3781.9-93 specifies several safety requirements. The instrument must be calibrated before and after each test, and the isocyclic carbon black sample must be handled with caution in order to prevent any potential hazardous accidents. The test must also be performed in a well ventilated area in order to reduce the risk of fire or explosions.
Isocyclic carbon black is an important industrial material, and its electrical resistance must be carefully measured in order to ensure correct performance in different applications. GB/T3781.9-93 outlines the test procedure and accuracy levels required to accurately measure the resistance of isocyclic carbon black. Following these standards helps to ensure the accuracy and safety of electrical resistance tests for isocyclic carbon black.
