3 APPROVED AND put INTO EFFECT by the Federal Agency for technical regulation and Metrology of 11 June 2014 No. 559-St

4 INTRODUCED FOR THE FIRST TIME

Application rules of this standard are established in GOST R 1.0−2012 (section 8). Information about the changes to this standard is published in the annual (as of January 1 of the current year) reference index «National standards» and the official text changes and amendments — in monthly information index «National standards». In case of revision (replacement) or cancellation of this standard a notification will be published in the upcoming issue of the monthly information index «National standards». Relevant information, notification and lyrics are also posted in the information system of General use — on the official website of the Federal Agency for technical regulation and Metrology on the Internet (gost.ru)

1 Scope

This standard specifies the gauge extruded profiles bulbous bandpass bandpass symmetrical and asymmetrical cross-sections of aluminum alloys manufactured by hot pressing and intended for use in shipbuilding.

2 Normative references

This standard used the reference standard to the following standard:

GOST 4784−97 Aluminum and aluminum deformable alloys. Brand

Note — When using this standard appropriate to test the effect of reference standards in the information system of General use — on the official website of the Federal Agency for technical regulation and Metrology on the Internet or in the annual information index «National standards» published as on January 1 of the current year, and the editions of the monthly information index «National standards» for the current year. If replaced with a reference standard, which was given an undated reference, then it is recommended to use the current version of this standard, taking into account all enabled in this version modifications. If replaced with a reference standard, which is given a dated reference, it is recommended to use the version of this standard referred to above by year of approval (acceptance). If after approval of this standard in the reference standard, which is given a dated reference, a change affecting a provision to which reference, the provision is recommended to be applied without taking into account this change. If the reference standard is cancelled without replacement, the position in which reference is made to him, recommended to be used in part not affecting this link.

3 Main parameters and dimensions

3.1 Form bulbous profiles bandpass symmetrical cross-section (bulb) and their sizes should correspond to the values given in figure 1 and in table 1, and reference indicators to the values specified in Annex A.

H — the height of the bulb; In — the width of the shelf; S — wall thickness;  — the radius of curvature of the edges of the shelves and the radius of the wall with shelf
