3 Terms and definitions

The terms and definitions defined by IEC 61196-1 apply to this document.

4 Ellipticity test

4.1 Principle The ellipticity of the cable is determined by measuring two orthogonal diameters on the cross-section of the finished cable specimen. 4.2 Test Equipment The resolution of the instrument is 0.01mm. The following instruments can be used. --- Microscope. Can be read to the third decimal place; --- Projection measuring instrument. Magnification at least 10 times; --- Caliper; ---micrometer. 4.3 sample preparation Three specimens were taken from the finished cable, each specimen having a cut-off interval of at least 100 mm. According to the relevant sub-specification or detailed regulations Make sure that the cross-section of each specimen should be cut flat and carefully clean the burrs. 4.4 Procedures The outer diameter of the cable was measured twice for each cross-section and the diameters measured should be perpendicular to each other. Each time a measurement is taken, an appropriate position is selected. Both diameters are perpendicular to each other and give their maximum difference. ......
