Notes:

1. The index of tensile strength in radial compression to 01.01.92 rejection is not a sign and is defined for statistical purposes.

2. The minimum acceptable hardness value of the material items (ГОСТ 26719-85 Материалы антифрикционные порошковые на основе меди. Марки (с Изменением N 1)) megapascal is determined by the formula:

ГОСТ 26719-85 Материалы антифрикционные порошковые на основе меди. Марки (с Изменением N 1),


where ГОСТ 26719-85 Материалы антифрикционные порошковые на основе меди. Марки (с Изменением N 1)is the minimum value of the hardness according to the table, MPa;

ГОСТ 26719-85 Материалы антифрикционные порошковые на основе меди. Марки (с Изменением N 1) — a correction factor characterizing the variation of hardness and porosity of the material. For materials brands PA-Man, PA-Bragr, PA-БрОГр2, PA-БрОГр4 and PA-Bloggr it should be 12.3; 8,3; 25,0; of 26.7 and 16.6, respectively;

ГОСТ 26719-85 Материалы антифрикционные порошковые на основе меди. Марки (с Изменением N 1) — the maximum value of the porosity of the material according to the table, %;

ГОСТ 26719-85 Материалы антифрикционные порошковые на основе меди. Марки (с Изменением N 1)the maximum porosity value for a prescribed interval porosity of the material in the normative-technical documentation for specific products, %.

3. The limit of Flexural strength, the tensile strength tensile and toughness of the antifriction powder materials based on copper in the reference Appendix 1.

4. Conditions of work and the scope of the materials is given in recommended Appendix 2.

5. Compliance notation antifriction powder materials based on copper previously used in the normative-technical documentation in the reference enclosure 3.

6. The symbol marks consists of letters and numbers. The letters indicate: P — belonging to the powder material, And assign material — antifriction, after the dash — based material and alloying elements: Br — bronze, D — copper, tin, Gr — graphite, W — iron, X — chrome.

The figures after the letters indicate the content of a particular element in materials of similar compositions, different percentages of the same elements.
