5.6. The microstructure profiles checked by metallographic method on a single sample or method of eddy currents according to the method of the manufacturer.

In the presence of burnout re-control of the microstructure is not allowed.

5.7. The presence of nitrate test applying to the surface profile in either place drops of 0.5% solution of diphenylamine in sulfuric acid (to the sample 0.5 g of diphenylamine poured 10 cmof distilled water and 25 cmof sulphuric acid of density 1.84 g/cm).

Upon dissolution of diphenylamine solution volume is adjusted to 100 cmby the addition of sulfuric acid density 1.84 g/cm. Intense blue drops of solution with 10−15 points to the presence in a given location nitrate. After the test drop is removed with filter paper and the tested area is washed thoroughly with water and wipe off.

Upon detection of nitrate party profiles must be re-washing and re-control the presence of nitrate in the surface profiles.

5.8. Electrical resistance profiles determined according to GOST 7229−76 or other methods to ensure the specified accuracy of the measurement.

In the presence of differences determination of electrical resistance is carried out according to GOST 7229−76.

(Added, Rev. N 3).

6. MARKING, PACKAGING, TRANSPORTATION AND STORAGE

6.1. Profiles are tied in bunches, to which is attached a label indicating the grade alloy, material condition, strength, batch number and the mark of the technical control Department of the manufacturer.

6.1.1. The profiles do not tie in bundles, must be embossed or painted: trademark of the manufacturer, the grade of aluminum or aluminum alloy as the material, strength, batch number and the stamp of the technical control of the manufacturer.

The mark is applied to the output end at a distance from the end of profile is not more than 20 mm for profiles with a flat part of more than 30 mm and not more than 50 mm for profiles with a flat portion from 15 to 30 mm.

(Added, Rev. N 1).

6.2. On profiles, from which were taken samples for mechanical testing, further cause the marking of the serial number.

6.3. Temporary corrosion protection, packaging, transportation and storage GOST 9.510−93.

(Changed edition, Rev. N 2).

6.4. Transport marking of packages — according to GOST 14192−77 with an additional label:

the name of the material;

grade;

the condition of the material and the kind of strength;

the number or code of the profile;

batch number.

6.4.1. Marking of profiles intended for export, is carried out in accordance with the order of foreign trade enterprises,
