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 applies to pipes and N-shaped cross section high precision and surface finish of aluminium and aluminium alloys intended for the manufacture of waveguides.

2 Normative references

This standard uses the regulatory references to the following standards:

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 it, it is recommended to accept in part not affecting this link.

3 Classification

3.1 Pipe waveguides are divided as follows:

in the form section:

— rectangular — OL,

— H-shaped — BUT;

for precision manufacturing:

— normal accuracy — no symbol,

— high precision — V.

3.2 N-shaped tubes are made only of high accuracy for pipes — normal and high precision.

3.3 Rectangular and H-shaped pipe is supplied in cold-worked condition — N.

4 Basic parameters and dimensions

4.1 the cross-sectional Dimensions of and tolerances for rectangular tubes of normal accuracy should conform to the values given in figure 1 and in table 1.
