INFORMATION DATA

1. DEVELOPED AND INTRODUCED by the Ministry of ferrous metallurgy of the USSR

2. APPROVED AND promulgated by the Decree of the State Committee of standards of Ministerial Council of the USSR from 23.12.75 N 3982

3. REPLACE GOST 3120−46

4. Limitation of actions taken by Protocol No. 7−95 Interstate Council for standardization, Metrology and certification (ICS 11−95)

5. EDITION (March 2002) with amendment No. 1, approved in October 1987 (ICS 1−88)

This standard applies to steel aircraft cables, used in control systems for aircraft, and establishes a method of pre-exhaust before operation.

1. EQUIPMENT

1.1. The extrusion of a rope can be made by means of any mechanism or machinery (winches, gates, etc.) with the use of pointer force (dynamometer, pressure gauge, etc.) attached to the rope, or by means of cargo, suspended from the end of the rope (if the hood is made in one end) or to block (if the hood is manufactured in multiple finishes).

1.2. Installation, the hood can be horizontal or vertical.

1.3. The diameter of the guide rollers or drum shall be not less than 1000ГОСТ 3120-75 Канаты стальные авиационные. Метод предварительной вытяжки (с Изменением N 1), where ГОСТ 3120-75 Канаты стальные авиационные. Метод предварительной вытяжки (с Изменением N 1)the diameter of the outer wire rope.

The radius of the grooves of the rollers or drum should be 0.5ГОСТ 3120-75 Канаты стальные авиационные. Метод предварительной вытяжки (с Изменением N 1), where a ГОСТ 3120-75 Канаты стальные авиационные. Метод предварительной вытяжки (с Изменением N 1)is the diameter of the rope. Maximum deviation radius of the groove 0.1 mm.

(Changed edition, Rev. N 1).

2. PREPARING FOR THE TEST

2.1. The rope, under hood, should not have structural defects.

2.2. The attachment of the ends of the rope should be done with kousei, clips, snails or any other method that does not allow slippage of the rope in places of its fastening under the action of efforts in making the extract.

2.3. Before sealing rope in the connecting fixtures of the end of his tie with a soft wire to prevent arbitrary raspletanie rope.

3. THE TEST

3.1. The cable stretching can be done at one end (Fig.1) and in a few ends (Fig.2−3).

3.4. When drawing rope in a few tips the amount of force must be increased in proportion to the number of ends of the rope (see the devil.3).

3.5. Force drawing ropes set (45±5)% of the breaking strength of the rope as a whole.
