Технические условия (с Изменениями N 1-5)is determined by means of a square according to GOST 3749, lying on one side on the plane of location of the ingot, and measuring with a ruler according to GOST 427 or probes on the other 2−034−225. Cosine of the cut is measured in both end planes and expressed in millimeters. Each dimension must correspond to claim 2.4.

Cosine of the cut ingots supplied for the cable industry, measured with a protractor with a Vernier type UN GOST 5378. The measurement is performed at each plane in four locations around the edge of the end face located through 90°. When measuring a fixed line, rigidly coupled to the base of the protractor, tightly pressed to the forming of the ingot in place without defects. A movable range of the goniometer is applied strictly to the diameter of the end face of the ingot and carry out the measurement of the angle ГОСТ 19437-81 Слитки алюминиевые цилиндрические. Технические условия (с Изменениями N 1-5)characterizing the cosine of the cut. Each of the angle measurements ГОСТ 19437-81 Слитки алюминиевые цилиндрические. Технические условия (с Изменениями N 1-5)shall not exceed: ±25' — for bars with cut ends, ±15' — for bars with machined ends, ±10' — from 01.01.93.

Allowed to measure the skew of the cut bars are designed for the cable industry, by means of a square according to GOST 3749 type, UL class 1 and probes on the other 2−034−225. The maximum allowable amount ГОСТ 19437-81 Слитки алюминиевые цилиндрические. Технические условия (с Изменениями N 1-5)determined by the formula

ГОСТ 19437-81 Слитки алюминиевые цилиндрические. Технические условия (с Изменениями N 1-5),


where ГОСТ 19437-81 Слитки алюминиевые цилиндрические. Технические условия (с Изменениями N 1-5) — the maximum value of the angle (25' or 15');

ГОСТ 19437-81 Слитки алюминиевые цилиндрические. Технические условия (с Изменениями N 1-5) — diameter of ingot, mm.

The ingots are considered to comply with the technical requirements, if

5. MARKING, PACKAGING, TRANSPORTATION AND STORAGE

5.1. At the end of each ingot must be marked with the following information:

trademark or the name and trademark of manufacturer;

the room melt;

the number of the ingot (not affixed, if melting consists of a single ingot);

grade of aluminium.

The number of melt is applied with a metal stamp. The height of the letters and figures shall be not less than 10 mm. the Rest of notation is applied with a metal stamp or indelible ink.

Bullion designed for the cable industry, not stigmatized and not mark. Markings is the trademark or name and trademark of manufacturer, grade of aluminum, the melting number and the symbol of the ingot indicated in the packing list or other supporting documentation.

(Changed edition, Rev. N 2).

5.2. Ingots weighing up to 500 kg formed into bundles weighing not more than 5 so the Formation of packages of ingots is carried out according to the rules of carriage of goods approved by the relevant departments. Each package should be sealed with bindings (one binding — one turn of wire rod), the amount of which depends on the mass of the package. For package weight not exceeding 2 tonnes, the number of studs must be at least 4, for packages weighing no more than 4 t — not less than 6, for packages weighing no more than 5 tonnes not less than 8.

As materials for bonding packages used aluminum rod with a diameter of not less than 9 mm according to GOST 13843, or other normative and technical documentation or annealed steel wire of diameter not less than 6 mm according to GOST 3282, or steel packing tape according to GOST 3560, GOST 4986 or other regulatory-technical documentation. Weight of wire rod is included in the net weight of the package and the party.

Means of binding is not designed to capture packets while performing loading and unloading operations.

Ingots with a mass of 500 kg and more no package.

At customer’s request bars weighing more than 500 kg package.

Bullion designed for the cable industry, must be Packed in boxes or containers made according to normative-technical documentation.
