Customer’s request wire diameter 2,50 and 3,00 mm are made of high accuracy with extreme deviation (minus) 0,06 mm.
(Changed edition, Rev. N 3, 4).
The legend is placed according to the scheme:
when the following abbreviations:
manufacturing method: cold-drawn — D;
sectional shape: round — CU;
accuracy of manufacturing: normal — N, high — P;
length: in rolls, coils — BT.
Example of designation of a wire of normal accuracy of manufacturing a diameter of 2.50 mm
Wire DCMH 2,50 BT C1 GOST 13073−77.
(Changed edition, Rev. N 2, 3, 4).
1.2. The roundness of the wire must not exceed the limit deviation for diameter.
(Added, Rev. N 3).
2. TECHNICAL REQUIREMENTS
2.1. Wire produced in accordance with the requirements of this standard for technological regulations approved in the prescribed manner.
Wire should produce zinc brand of C1 with the chemical composition according to GOST 3640−79.
(Changed edition, Rev. N 2).
2.2. The surface of the wire must be clean, non-oxidized, no cracks and delamination.
Allowed individual surface defects not present in the control wire Stripping for limit deviation for diameter. On the surface of the wire allowed the grease.
Customer’s request wire is covered with preservative grease.
(Changed edition, Rev. N 4).
2.3. (Deleted, Rev. N 3).
2.4. (Deleted. Izm. N 4).
3. ACCEPTANCE RULES
3.1. Wire take parties. The party should consist of wire of the same diameter, the same precision workmanship and must be issued a document about quality that contains:
trademark or the name and trademark of manufacturer;
symbol wire;
the weight of the party;
batch number.
The weight of the batch shall not exceed 1000 kg.
(Changed edition, Rev. N 2, 3).
3.2. Checking size and quality of the surface subjected to each coil of wire.
(Changed edition, Rev. N 2, 3).
3.3. To check the chemical composition of the selected two rolls from each batch.
The manufacturer checks the chemical composition can produce by samples taken from the molten metal.
(Changed edition, Rev. N 1, 3, 4).
3.4. If unsatisfactory results of the determination of the chemical composition of at least one sample, repeat the test of the doubled sample taken from the same batch. The results of repeated tests apply to the entire party.
(Changed edition, Rev. N 3).
4. TEST METHODS
4.1. Inspection of the wire surface is produced without the use of magnifying devices.
4.2. Determination of the diameter and ovality of wire produce in two mutually perpendicular directions of the same section of wire at the beginning, end and middle of the strand with a micrometer with scale interval of 0.01 mm according to GOST 6507−90.
Allowed to control the diameter of the wire other tool, to ensure appropriate measurement accuracy.
If there is disagreement in the determination of the wire diameter is measured with a micrometer according to GOST 6507−90.
(Changed edition, Rev. N 3).
4.3. To determine the chemical composition of each selected coil cut on the same model. Selection and preparation of samples for the determination of chemical composition is carried out in the churchyard 24231−80.
The chemical composition of the wire is determined according to GOST 19251.0−79-GOST 19251.6−79 or other methods providing the required accuracy.
If there is disagreement in the assessment of the chemical composition wire analysis is carried out according to GOST 19251.0−79−19251.6 GOST-79.
(Changed edition, Rev. N 3).
