Note. Theoretical weight of 1 mГОСТ 89-73 Роли свинцовые. Технические условия (с Изменениями N 1, 2, 3)of roles given in the Appendix.

1.2. Limit deviations on width should not exceed ±1%.

1.3. (Deleted, Rev. N 2).

The legend is placed according to the scheme:

ГОСТ 89-73 Роли свинцовые. Технические условия (с Изменениями N 1, 2, 3)


when the following abbreviations:

manufacturing method: cold-drawn — D;

sectional shape: rectangular — OL;

length: random — ND.

Example of designation of a roller with a thickness of 10.0 mm, a width of 2800 mm from the lead of C1 grade:

The role DPRH 10,0х2800 ND C1 GOST 89−73.


(Changed edition, Rev. N 2).

2. TECHNICAL REQUIREMENTS

2.1 a. The role must be manufactured in accordance with the requirements of this standard for technological regulations approved in the prescribed manner.

(Added, Rev. N 2).

2.1. The role of produce from lead brands C1 and C2 according to GOST 3778−77.

2.2. The surface of the roles should be clean and smooth, no shells, bundles, deep dents, bubbles, scratches, pits and foreign inclusions.

On the surface the roles are not allowed defects when they control the sweep output dimensions within tolerances for thickness.

On the surface of the roles allowed white bloom.

The ends and edges of roles needs to be trimmed evenly. On the edge roles are not allowed damage to bigger than 10 mm from the edge.

Cut end Squareness, mm should take role over the limit deviations on width.

(Changed edition, Rev. N 2).

3. ACCEPTANCE RULES

3.1. Take the role of the parties. The party should consist of roles of the same size, the same brand of lead shall be furnished in one document about quality that contains:

trademark or the name and trademark of manufacturer;

designation of roles;

the weight of the batch;

batch number;

the number of seats.

(Changed edition, Rev. N 2).

3.2. Inspection and measurement needs to be subject to each party’s role.

3.3. To check the chemical composition of the three selected control from the party to the mass party is not more than 10000 kg and in addition one control from each subsequent 10000 kg weight of the batch is more than 10,000 kg.

Allowed the manufacturer of the sampling to produce from molten metal.

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

The results of repeated tests apply to the entire party.

3.3, 3.4. (Changed edition, Rev. N 2).

4. TEST METHODS

4.1. The surface inspection roles must be carried out without the use of magnifying devices.

4.2. The measurement of the thickness of roles carried out by micrometer according to GOST 6507−90 at a distance of not less than 100 mm from the corner of the monitor and not less than 20 mm from the edge.

Measurement of the width of the roles carried out metal measuring tape according to GOST 7502−89 or other tool, to ensure appropriate measurement accuracy.

4.3. To check the chemical composition of each selected control cut out one sample. Selection and preparation of samples for the determination of chemical composition is carried out according to GOST 24231−80. The chemical composition of roles is determined according to GOST 20580.0−80 — GOST 20580.8−80.

4.2, 4.3. (Changed edition, Rev. N 2).

4.4. (Deleted, Rev. N 2).

5. MARKING, PACKAGING, TRANSPORTATION AND STORAGE

5.1. Each role must be applied with branding on one of the outside corners:

trademark or the name and trademark of manufacturer;

brand lead;

dimensions of the role;

weight control;

batch number;

the designation of this standard.

5.2. The role should be rolled into rolls and Packed in lattice boxes type I-2 or II-2 according to GOST 10198−91.

Allowed products packaging during transport in covered vehicles.

Weight of cargo must not exceed 3000 kg.

5.3. Packaging of products transported in the far North and remote areas — according to GOST 15846−79, the group «Metals and metal products."

5.4. Transport marking — according to GOST 14192−96.

5.5. The role transporterowych by all kinds of transport in covered vehicles in accordance with cargo carriage regulations applicable to transport of this species. It is allowed to transport by rail on the open rolling stock in accordance with the conditions of loading and fastening of cargoes. Railway transportation — small, low-tonnage and carload shipments. In carload shipments the loading and unloading of roles carried out on access roads to the shipper and the consignee.

(Changed edition, Rev. N 3).

5.6. The role should be stored in covered premises. Consumer role properties are not changed.

(Changed edition, Rev. N 2, 3).
