3 Terminology
3.1 Quick-pull speed
The maximum moving speed of the tester when there is no sample. 3.2 Space inside the box
DC resistance test device
Elongation tester
Rebound angle tester
Snap break tester
Residual tester
Electric heating forced ventilation test box
Softening breakdown tester
One-way paint scraping tester
Solvent resistance tester
Breakdown voltage tester
Low voltage paint film continuity tester
High voltage paint film continuity tester
The space defined by the inner wall of the electric heating forced ventilation test box, i.e., by the dimensions of depth, width and height. 3.3 Space temperature deviation
The temperature deviation between different positions in the box space at the same time after being adjusted at a given temperature and reaching a thermally stable state. 3.4 Temporal temperature fluctuation
After reaching a thermally stable state under a given temperature regulation, the temperature fluctuation caused by the regulator working mode at different times at the same position in the box.
3.5 Temperature deviation
Approved by the Ministry of Machinery Industry on December 9, 1994
Implementation on June 1, 1995
JB/T 4279.1-94
The temperature deviation between different positions at the same time (spatial temperature deviation) and at different times at the same position (temporal temperature fluctuation). 3.6 Working space
The space used to place the sample in the box space that meets the temperature range specified in the relevant enameled winding wire test method standards. The working space is not less than the space occupied by the sample, and its interface is parallel to the interface of the box space. 3.7 Sensitivity of defect detection circuit
The minimum current of the counter action in the defect detection circuit. 3.8 Scraping force error
After the paint film of the sample is scratched and the tester stops scraping, the relative error of the product of the load and the corresponding scraping force coefficient compared to the force value of the scraping needle actually borne by the sample. Digital rounding of measurement results
The digital rounding of measurement results shall be in accordance with the provisions of GB8170. Verification and calibration of calibration instruments
All instruments used for calibrating test instruments and equipment in this standard shall be calibrated or calibrated regularly in accordance with the regulations to ensure the accuracy of the calibration instruments.
Verification certificate and verification result notice sample standard verification certificate and verification result notice of test instruments and equipment in each part. Except for the parts already given in the verification method, they shall be in accordance with the provisions of Appendix A and Appendix B of this standard.
