requirements of Table 2. The allowable deviation of the diameter of the straight steel
wire shall meet the requirements of Table 3.
6.1.2 For the length deviation of the straight steel wire, it shall select an appropriate

such as pull marks, tears, rust, burrs, etc., which have obvious adverse effects on the
application of the steel wire.
7.3.2 The steel wires (DM and DH), for dynamic load springs, shall be subjected to
surface inspection. The radial depth of cracks or other surface defects shall comply with
the requirements in Table 6. By mutual agreement, eddy current testing can be carried
out.

galvanized or plated with zinc-aluminum alloy. If there is requirement, it shall be
negotiated separately.
7.5 Process performance
7.5.1 Winding test
When requested by the purchaser, the steel wire, which has a nominal diameter of less
than 3.00 mm, may adopt winding test; it shall not have any cracks.
7.5.2 Torsion test
7.5.2.1 The torsion test shall be carried out, for the steel wire which has a nominal
diameter in the range of 0.70 mm < d ≤ 6.00 mm. For the steel wire, which has a nominal
diameter in the range of 6.00 mm < d ≤ 10.00 mm, the torsion test shall be determined,

8.3 Surface quality
8.3.1 Visual inspection shall be adopted, for the appearance and surface quality.

metallographic method. Acid leaching can be used for steel wires, which have a nominal
diameter of not less than 2 mm; there shall be no surface defects after acid leaching. In
case of dispute, it shall use the metallographic inspection. The acid leaching test method
is as follows: Before the test, the specimen can be subjected to stress relief treatment;
then the normal temperature specimen is immersed in a solution, which has a

leaching is terminated, after the diameter is reduced by about 1%. Visually check
whether there is surface defect.
8.4 Mechanical properties
The tensile strength shall be calculated, from the measured diameter.
When measuring the size required for calculating the reduction of cross-section, the
measurement error shall not be greater than ±1%.
8.5 Process performance

which has a diameter equal to its own diameter. Then the surface is visually inspected.
8.5.2 Method of bending test: Bend the steel wire 180° around a mandrel into a U shape;
then visually inspect the surface. For steel wires, which have a nominal diameter greater
than 3.00 mm but not greater than 6.50 mm, the diameter of the mandrel is twice the
nominal diameter of the steel wire. For steel wires, which have a nominal diameter
greater than 6.5 mm, the diameter of the mandrel is three times the nominal diameter
of the steel wire.
8.5.3 Coil spring test method: Take a specimen, which is about 500 mm long. The steel
wire is tightly wound, by a relatively uniform slight tension. The diameter of the
mandrel is 3 ~ 3.5 times the nominal diameter of the steel wire, which is not less than
1.00 mm. Then pull open the steel wire ring next to each other, so that the static length
after unloading is about 3 times the original length.
8.6 Other test methods
Other test methods shall comply with the provisions of Table 8.
9 Inspection rules
9.1 Inspection and acceptance
Unless there is a special agreement between the supplier and the buyer, all tests shall
be carried out at the supplier's premises.

number (or the same production batch number), the same shape, the same dimension,
the same delivery state.
9.3 Spot check and sampling
The sampling location is any end of a piece of steel wire; take one sample from each
piece.
Sampling ratio requirements shall be in accordance with Table 8. When taking 10% of
the number of steel wire pieces, in each production batch, take a maximum of 10 pieces;
but for a batch of 20 pieces or less, take at least 2 pieces.
9.4 Re-inspection
