1 Scope

This standard applies to profiles of aluminium alloys aluminium-magnesium-silicon made by hot pressing and intended for use in translucent enclosing structures of buildings and structures.

The requirements of this standard apply to profiles-semi-finished and finished profiles (more profiles) with a diameter of circumscribed circle of 300 mm, as well as for combined profiles with a diameter of circumscribed circle of each of the aluminum element to 300 mm inclusive.

The requirements set out in paragraphs 4.6, 4.7, paragraphs 5.2.1, 5.2.2, 5.2.5, 5.2.6, 5.2.8−5.2.10, 5.2.12, 5.3.1−5.3.5, sections 5.4, 5.6, sections 6 and 7 of this standard are mandatory.

Allowed the use of profiles for the manufacture of opaque enclosing structures of buildings and structures with a corresponding feasibility study.

(Changed edition, Rev. N 1).

2 Normative references

The list of normative documents, links to which are used in this standard are given in Appendix A.

3 Definitions

In this standard use the following terms with respective definitions:

Profile — extruded product with desired size and shape of the cross section.

Solid profile profile in cross section which lacks an internal hollow space (figure 1).

Figure 1

The hollow profile is a profile section which includes one or more inner hollow spaces (figure 2).

Figure 2

The combined profile — a product in which the inner and outer elements are made of aluminium profiles one brand of alloy, connected by a thermometer insert from a material with lower thermal conductivity and to which, along with other requirements as to the resistance to heat transfer.

Combination profiles may consist of solid and hollow profiles of any configuration, connected by a thermostatic (figure 3).

1, 4 — hollow profiles; 2 — heat insulation chamber filled with air or foam
insulating material; 3 — thermometer insert

Figure 3

Ready profile — a profile that has a decorative and protective layer (hereinafter, profiles).

Profile-prefabricated profile having a protective and decorative coating.

The front surface profile — the surface profile, which is visible in the assembled condition of the structure and which impose requirements in terms of appearance.

Deviation from straightness — deviation of the longitudinal axis, or any edge profile from a straight line.

The deviation from flatness is the maximum distance from surface points of the profile adjacent to a horizontal or vertical plane.

Waviness is the deviation from flatness, having the character of periodically alternating ridges and troughs.

Torsion — deviation form, characterized by the rotation of the cross section around the longitudinal axis of the product.

Profile system — a set of sections forming a structural system enclosing translucent structures specified purposes (Windows, doors, stained glass Windows, storefronts, etc.), as reflected in technical (design) documentation.

4 Classification and designation

4.1 Profiles klassificeret:

— condition of the material;

hardened and artificially aged — T1, T6, T64;

fully hardened and artificially aged T5;

hardened and artificially aged high strength — T1 (22), T1 (25), T66.

4.3 According to the type of cross section profiles are divided into solid and hollow.

Composite profiles should be attributed to the hollow profiles with multiple interior spaces.

4.4 accuracy of manufacturing, the profiles are divided into types:

N — normal	precision	of manufacture;
P — high	»	"
PR — precision	"	"

4.5 Ready-made profiles are made treatment:

APPENDIX B
(required)

The essence of the method consists in determining effort, in which there is displacement of thermostable along one of the aluminum elements combined profile.

The requirements of this method apply to combined profiles with a protective and decorative coating and without it (profiles-semi-finished products).

B. 2 preparation for the test

To determine the bearing capacity of composite profile in terms of resistance to shear upon application of a short-term shear loading from the monitored party select three profiles of the same section. From the edge profile of each cut perpendicularly to the longitudinal axis of the profile of one sample with a length of (100±1) mm. the Test is carried out at a temperature of (20±3) °C and relative humidity (60±5)%.

Determination of bearing capacity of combined profiles in the device for testing the shear stability is carried out according to the scheme And, in a tensile testing machine according to the scheme B (figure B. 2).

B. 2 preparation for the test

From the monitored party selected three profiles. From each edge of each profile cut perpendicular to the longitudinal axis of one sample of a given length. The length of the sample depends on the type of used tensile machine and is usually (100±1) or (50±1) mm. the Test is carried out at a temperature of (20±3) °C and relative humidity (60±5)%. Depending on the type of testing machine allowed the use of samples of length less than (18±1) mm subject to obtaining results comparable to the results obtained when testing samples with a length of (100±1) mm.

B. 3 testing

The sample is rigidly fixed in a universal clamping device according to figure B. 1, is placed in a universal tensile machine and carry out the loading of the sample with a velocity of (1±0,1) to (3±0,1) mm/min to effort, corresponding to the destruction of the composite profile on the thermometer insert. The force is determined by a pronounced stop the arrows or the digital indicator of the force measuring device.
