put the notes in new edition:

"Notes:

1. It is allowed to produce cuttings for garden shovels with a diameter of 35 mm.

2. For blades of LOW and LOU types, it is allowed to manufacture cuttings without a conical part.

3. It is allowed to produce conical seats for cuttings for garden shovels with 2 angles of inclination.

Clause 2.2. Second paragraph. Delete the words: "except construction shovels"; replace the reference: GOST 380-71 with GOST 380-88.

Clause 2.7. Delete the word: "ripples".

Clause 2.8. Replace the word: "welded" with "welded or riveted";

Table 2 is supplemented with a note: “Note. Shovels with a blade width of 150 mm must withstand a bending moment force when testing the blade 160 N * m. Tuleyka at the point of transition into the blade of shovels with a handle diameter of 35 mm must withstand a bending moment of 300 N * m.

Paragraph 2.9 shall be supplemented with the words: "By agreement with the consumer, it is allowed to manufacture shovels of LOW and LOW types with a cylindrical body."

Clause 2.14. Delete the first paragraph; delete the words: "(except for LR-type shovels)".

Clause 2.19. Replace the word: "coated" with "coated with NC-type nitro paints".

(Continued see p. 90)

Paragraph 2.23 shall be reworded as follows:<2.23. Черенки диаметром 40 мм должны выдерживать изгибающий момент 440 Н*м, а черенки диаметром 35 мм - 300 Н*м».

Clause 2.24. Replace roughness parameter: Rm max<60 мкм на #/я тах < <63 мкм.

Paragraph 2.28 shall be supplemented with the paragraph: “In agreement with the consumer, other packaging is allowed to ensure the safety of shovels from mechanical damage and corrosion during transportation and storage.”

Clause 2.29. Replace designations: P-2, P-3, P-4 with II-2, P-Z, 11-4.

Paragraphs 4.4, 4.5 shall be reworded: “4.4. The strength of the shovel blade is checked in a fixture that clamps the blade at a distance of 115 mm from the cutting edge.

After loading the web with a full bending moment and removing the load, the position of the handle is fixed at the same distance. The difference in measurements should not exceed 7 mm.

The zone of transition of the tulle to the web (from the advance line to the end of the tulle or the lining), as well as welded and riveted joints, are checked for strength in a device that ensures their loading with the bending moment specified in clause 2.8, while the lower support should be located on the advance line. The specified zone and connections must withstand a bending moment for 1 min.

4.5. The strength of the handle should be checked in a device simulating a tulle by applying a bending moment in accordance with paragraph 2.23. After testing, the handle should not have cracks or delaminations.

Delete the application.
