3.3. To test the strength of adhesions, the deviation from the flatness, elasticity, straightness, fragility, temporary tear resistance take 3% of the skeins, but not less than five skeins by weight of the party.

3.1−3.3. (Changed edition, Rev. N 1).

3.4. If unsatisfactory test results of at least one of the indicators it is carried out re-testing at twice the sample.

The results of repeated tests spread to the entire party.

4. TEST METHODS

4.1. For each test taken one sample from each end of the strand.

4.2. The height of the wire is checked with a micrometer according to GOST 6507 at the ends of the roll. Width and limit deviations on width is defined as the total value of the height of the wire.

4.3. The surface quality of the wire is checked visually. Allowed the use of a magnifying glass 5of the increase.

The differences in the assessment of the quality of the wire surface (availability not covered by the tin sites) monitoring for this indicator is carried out by immersion.

For the test samples of wire 150 mm in length cut from the roll without buckling and bending.

Before the test, samples of wire to remove dirt and grease washed with gasoline, benzene or ether, and then further distilled water. The washed samples wipe dry with cotton or a clean cloth.

The samples were then immersed in a solution of chemically pure hydrochloric acid density 1,088 g/cmto 10 s, to detect uncovered areas in zhelezovanadievoj solution of potassium with a mass fraction of 2.5% for 30 sec.

When testing wire, the temperature of the filtered solutions of hydrochloric acid and potassium relatoseroticos should be (20±10) °C.

After which the samples are immediately rinsed in water and wipe with cotton or a clean cloth.

The depth of immersion of samples in solutions of 100 mm.

Samples of wire must be solutions of acid and potassium relatoseroticos stationary, not in contact with each other and with the walls of the vessel.

The wire is considered satisfactory if not on its surface appear blue spots or faint blue coloration of the entire surface or entire sections of the blue or dark color.

Allowed blue wire surface at the height of the solution level and at a distance of 20 mm from the immersed in the solution of end of the wire.

4.4. To check the strength of adhesions of the constituent wires of the sample of wire round around a round core 360°, followed by a twist of the specimen ends a half-turn parallel to the rod. Splitting the wire into components is not allowed.

The diameter of the rod should be:

(3±0.1) mm — for wire size 0,34х0,68; 0,35х0,70; 0,40х0,80 mm;

(5±0,1) mm for wire size 0,50x1,00; 0,60х1,20; 0,70х1,40; 0,80х1,60 mm.

4.2−4.4. (Changed edition, Rev. N 1).

4.5. Check the wire on the deviation from the plane (screw) is performed using a device, scheme of which is given in the Appendix. Length check sample should be 750 mm.

To check the wire on the deviation from the plane of one end of a sample length of 40−50 mm is bent at a 90° angle to the longitudinal axis of the wire, then the sample is placed on a horizontal plate strictly control risk at the curved end to the protractor, is pressed against the plane of the table at two points A and To clamp and fix the deviation of the folded end of the scale of the protractor, then sample free point In and fix the new position of the folded end of the scale of the protractor.

The difference between the first and second deviation of the folded end of the sample on the scale of the protractor is the deviation from the plane (screw) in degrees (°).

4.6. To check the wire on the elasticity of the ends of the test sample, connect to receive shapes in the form of a circle, then the wire ends are released and the sample is placed on a surface plate according to GOST 10905. A sample of wire shall be in contact with the plane of the plate along the entire length.

The length of the sample to check the wire on the elasticity must be:

300 mm — for wire size 0,34х0,68; 0,35х0,70 mm;

400 mm — wire size 0,40х0,80; 0,50x1,00 mm;

500 mm — for wire size 0,60х1,20 mm;

700 mm — for wire size 0,70х1,40; 0,80х1,60 mm.

(Changed edition, Rev. N 1).

4.7. Check wire straightness is performed on the device, whose scheme is shown in the Appendix. Length check sample should be 700 mm.

To check the wire to check the straightness of the specimen put on the table of the device along the control risks and combine it throughout its length with a check mark.

Check the measurement deviation of the sample from the control risks carried out using a measuring ruler according to GOST 427, attached to the instrument device.

4.8. To check the wire on the fragility of the test sample and make a loop branches of the loop is stretched before the formation of a straight line and not twisting the formed loop, the branches of it together in the opposite direction stretch, until the convergence of the branches (drawing).

4.9. Check each component of the wire tension is carried out according to GOST 10446. Rupture strength is determined by the actual diameter of the check sample.
