Steel cord test method
1 Scope
This standard specifies the test principle, test equipment, sample preparation, test procedure for the performance test method of the steel cord for radial tire,
Test report and so on.
This standard is applicable to the test of steel cord for radial tire (hereinafter referred to as "steel cord"), including appearance quality, size performance, process
Mechanical properties, coating chemical properties and adhesive properties of the test.
2 Specimen General
For test steel cord samples, need to use the fuse from the finished product wheel, and to ensure that the sample without loose, bending, damage, etc.
Trap, outside the wire around the structure of the sample should ensure that both ends of the fuse around the wire and the core strand is not well connected between the loose. For chemical performance testing and bonding
The test specimen of the performance test shall ensure that the surface of the specimen is free of contamination. If necessary, pull out a certain length of steel cord discarded and then take the test sample.
3 appearance quality
Visual inspection of steel cord appearance whether there are back wire (back), as the core, flip, blister, coil, wave, hard bend and other defects.
4 size performance
4.1 steel cord diameter
4.1.1 Micrometer measuring steel cord diameter
4.1.1.1 Test equipment
The test equipment is as follows.
a) Public micrometer, recommended non-rotating mandrel micrometer, see Figure 1.
Measuring range. 0mm ~ 25mm, accuracy. 0.001mm.
Measuring end face. rounded face diameter greater than the measured sample a twist; measuring force range. < 10N, recommended 3N ~ 5N.
Recommended use. Flatness Tolerance range. 0.002mm; Parallelism Tolerance range. 0.015mm.
