This standard applies to cold-formed profiles of aluminum and aluminum alloys, manufactured by roll forming mills and intended for cladding of building structures.

1. ASSORTMENT

1.1. The purpose of the profiles are divided into types:

A — for walls, partitions and coverings;

PA for skins of sandwich panels;

SA — for suspended ceilings, cover strips, protective devices and other structures for special purposes.

1.2. The symbol of the profiles taken in accordance with the scheme.

Example of designation of the aluminium profile of type SA with a height of 20 mm, a width of 300 mm, a sheet thickness of 0.8 mm, having perforation (p) from the aluminum strip alloy grade AMC, annealed (M) according to GOST 13726−78:

1.3. Form of sections, dimensions, square cross sections, weight of 1 m length and 1 m, and the reference size profiles should match those in hell.1−14 and in table.1−14.

(Changed edition, Rev. N 1).

1.4. Profiles should be made:

lengths from 1.2 m to 7.8 m for profiles such As;

multiple (300 mm) lengths from 1.2 m to 7.8 m — type profiles of the PA and the SA.

2. TECHNICAL REQUIREMENTS

2.1. Profiles shall be manufactured in accordance with the requirements of this standard working drawings, approved in the prescribed manner.

(Changed edition, Rev. N 1).

2.2. Profiles shall be made of aluminum strip according to GOST 13726−78 or sheets according to GOST 21631−76 aluminum brand AD1 and alloys AMTS, Amg2 thickness 0,6; 0,8; 1,0 mm normal accuracy in thickness and a normal surface finish.

The delivery condition of the material profiles for all brands: no heat treatment, annealed (M) and polunagartovannye (N).

2.3. On the surface of the profiles is not allowed:

crack, flaw, delamination;

risks depth exceeds the value of the negative deviation of the thickness profile.

Other requirements to the surface quality of the profiles according to GOST and GOST 21631−76 13726−78.

2.4. Limit deviations of the dimensions of the profiles from the nominal shall not exceed specified in table.15.

Table 15

mm

Profile settings	Limit deviation of the profile
highest quality	the first category of quality
Height	±1,0	±1,0
Width:
up to 1000	±3,5	+3,5
St 1000	±5,0	±5,0
Length:
to 3000	±6,0	±8,0
St 3000	±8,0	±10,0

Dimensions for which the maximum deviations are not installed, the profiles are not in control. Step width, radius of curvature and depth of the corrugations is controlled in bore rolls.

(Changed edition, Rev. N 1).

2.5. Maximum deviations in thickness of sections should correspond to the limit deviations on thickness of metal blanks according to GOST and GOST 21631−76 13726−78. Maximum deviations do not apply to variations in the thickness profile in areas of bending.

2.6. Waviness of the edges of profiles should not exceed 5 mm per 1 m length of the profile. In the profiles with the free side edges 70 mm is allowed waviness with an amplitude of 25 mm.

2.7. The perpendicularity tolerance of the edges of profiles should not exceed 5.0 mm in width. For profiles of the highest quality tolerance Squareness of the edges shall not exceed 3.0 mm in width.

(Changed edition, Rev. N 1).

2.8. On the end and side edges of the profiles are not permitted by local crushing depth of more than 3 mm.

2.9. In agreement with the manufacturer of profiles can be supplied with protective coatings in accordance with SNiP II-28−73.

3. COMPLETENESS

3.1. Package should include:

profiles of the same size and brand aluminum alloy;

the document about quality (certificate) for shipped products.

4. ACCEPTANCE RULES

4.1. Profiles must be accepted by the technical control of the manufacturer parties. The party should be considered to be profiles of the same size, made during the shift from one kind of workpiece, with one installation of main rolls, one of alloy grades and the delivery conditions of the metal.

4.2. The appearance test is subject to each profile.

4.3. For the control profiles for compliance with the requirements of PP.2.4−2.8 take away 5% of profiles from the party, but not less than 3 pieces.

4.4. Party is considered accepted if the indicators of the quality of the profiles meet the requirements of this standard.

4.5. If unsatisfactory results control at least one of the quality indicators, it is carried out repeated monitoring on twice the number of samples taken from the same batch.

If re-inspection will be at least one profile that does not meet the requirements of this standard, the entire batch is subjected to routine acceptance.

4.6. The consumer has the right to make test verification of compliance profiles with the requirements of this standard, respecting the order of selection profiles and applying these control methods.

5. CONTROL METHODS

5.1. The surface quality of the profiles is determined visually.

5.2. Control of linear dimensions of profile measurement tool: measuring tape according to GOST 7502−80, class 2, metal ruler according to GOST 427−75, changereason according to GOST 164−80 caliper according to GOST 166−80. The width and height of the profiles measured at a distance of 500 mm from the ends of the profiles or in the midline.

(Changed edition, Rev. N 1).

5.3. Waviness profile and check using the calibration line according to GOST 8026−75 and caliper according to GOST 166−80 or gauges according to GOST 162−80.

5.4. The perpendicularity tolerance and the crushing of the edges of the profiles, check a square churchyard 3749−77 and a set of probes according to GOST 882−75 or ruler according to GOST 427−75.

5.5. The quality and thickness of the protective coating is controlled according to SNiP III-23−76.
