The re-release (as of April 2008)


This standard applies to sheets of aluminium and aluminium alloys, designed for the needs of the national economy and exports.

(Changed edition, Rev. N 3).

2*. CLASSIFICATION

_______________
* Numbering corresponds to the original. — Note the manufacturer’s database.

1.1. The leaves are divided:

a) according to the method of manufacture:

replacerange — without additional marking;

clad — with technological plating — B,

with normal plating — And, thickened by plating.

b) as materials:

without heat treatment — without additional marking.

Note. The leaves are manufactured without heat treatment, in addition to sheets of alloy grade VD1 is allowed to be annealed;


annealed — M;

Note. Annealed sheets are allowed to manufacture without heat treatment if they meet the requirements of annealed sheets for mechanical properties, surface quality and flatness. Such leaves are marked with a letter M in brackets (M);


polunagartovannye — H2,

cold-worked — N,

hardened and naturally aged — T

hardened and artificially aged — T1

cold-worked after quenching and natural aging — TN;

C) the quality of surface finish:

high finish,

high finish — P,

the usual finish — no symbol.

Notes:

1. Leaves a high finish are manufactured with a thickness up to 4.0 mm.

2. Marking the quality of surface finish and P is after the last two digits of the approval year of the standard.

3 Sheets with high surface finish are made from aluminum grades A7, A6, A5, A0, AD00, AD0, AD1, HELL, and aluminum alloys AMTS, Amg2, and leaves with high and normal surface finish manufactured from all grades of aluminum and aluminum alloys;

d) for precision manufacturing:

high accuracy in thickness, width, length, or one or two of these parameters — P;

normal accuracy in thickness, width, length — without additional marking.

(Changed edition, Rev. N 1, 2, 3).

Notes:

1. Limit deviation of the sheets annealed and without heat treatment with a thickness of 5 mm or more from the alloys of AMGZ, AMg5 and AMg6 installed ±5% of nominal thickness.

2. In the manufacture of sheets of intermediate sizes thickness tolerances for sheet thickness for these sizes are accepted as the nearest smaller size.

3. Theoretical mass () of the running meter of the sheet, kg, is calculated by the formula:

where and  — maximum size limits on thickness and width, mm;

and the smallest size limits on thickness and width, mm;

 — density aluminum alloy, g/cm.

The theoretical mass of one running meter of the sheet is given in Appendix 2 (table 1−3) and calculated with a density of 2.85 g/cm, which corresponds to the density of aluminum alloys V95, and V95−1, B95−2.

To calculate the theoretical weight of sheet of other aluminum alloys should use the conversion factors listed in Annex 3.


(Changed edition, Rev. N 2).

Notes:
1. At the request of the consumer annealed sheets of aluminium are manufactured with a temporary temperature- tion not exceeding 110 MPa (11 kgf/mm). 2. Sheets of alloy grade AMC thickness from 1.0 to 4.0 mm in polonikeman condition at the customer’s request is made with the temporary resistance from 147 MPa (15,0 kgf/mm) to 196 MPa (at 20.0 kgf/mm).

(Changed edition, Rev. N 1, 2).

3.5. The mechanical properties of the annealed sheets subjected to quenching and aging, as well as hardened and aged sheets that have passed pertamaku and aging of the consumer, shall meet the requirements specified in table.8.

3.6. The leaves should be cut off at the ends at right angles. Cut end Squareness, mm shouldn’t print the sheets for tolerances for width and length. On the edges of cut sheets are not allowed burrs and separation, tears and cracks. The sheets, manufactured widened in accordance with the note to table.3, allowed tears and cracks on the edges, if they cannot make the sheet beyond the nominal width.

3.5−3.6. (Changed edition, Rev. N 1).

3.7. The surface of leaves of all groups finish should be gloss or frosted, without cracks, flaws, delaminations, bubbles, burned, RAID nitrate, spots of corrosion origin, diffusion spots (on the leaves with a thickness of more than 0.6 mm with normal and thickened plating), inclusions, exposed from the plating sections (on leaves with normal and thickened plating), as well as blurred whitish spots, resulting in the hardening, and non-metallic inclusions of metallurgical origin, if they are not removed in the control etching of 5−6%-nom solutionat 50 °C for 1−3 min with further clarification in 30% strength solution . On sheets of alloy grade AMC is not allowed grain size determined by the surface roughness of specimens subjected to tension in excess of the amount specified in mandatory Appendix 1.

3.8. On the front side of sheets of high surface finishes are not permitted: spots and stripes from the burnt grease, fingerprints from the rolls in the form of light and dark bands and tears.

The roughness parameter of the surface of the sheet should be no more than =1,25 µm according to GOST 2789.

(Changed edition, Rev. N 1, 3).

3.8.1. On the face of the leaves high finish allowed:

a) metal fine sunsets with a total area of not more than 20 mmper 1 mof the surface sheets with the width up to 1200 mm inclusive not more than 50 mmper 1 mof the surface sheets of a width more than 1200 mm;
