Type of use column, the medium and surface blood state . Increase the diameter of the pin to about 1:
In the diameter deviation of the element, increase the diameter deviation from 3 to 3, and increase the test length.
The tensile strength and elongation of different grades are obtained. For the linearity of different wire densities, the vertical method and the chord method are used to test the test results. The attached requirements are written, and the calculation formula for converting the wire weight of 200 strands of wire into the average diameter is given. The theoretical treatment of each grade of tungsten wire is given.
During the test period, the normal sampling plan is replaced by the standard for the household distribution. . Appendix A of this standard is a normative appendix, and Appendix and Appendix C are informative appendices.

Take three measuring points at a distance of 1= from the end. The value is the average of the three-point measurement results. For tungsten wire with a diameter of less than 350 mm, use a 200 mm wire segment to measure the diameter. Take 2 mm segments at both ends of the wire and measure with a dynamic balance or electronic balance. The balance value is the mass of the 2 m segment. The balance should comply with the requirements of Table 5.
