TECHNICAL REQUIREMENTS

2.1. The woven mesh must be manufactured in accordance with the requirements of this standard according to the technological regulations approved in the established manner, from low-carbon uncoated or galvanized wire of normal manufacturing accuracy according to TU 14-4-1563-89.
Grids of the 1st group should be made of wire with minus limit deviations equal to the sum of the absolute values of limit deviations.
(Changed edition, Rev. No. 1, 3).
2.2. Each spiral should consist of one wire.
2.3. Adjacent spirals must be woven into each other with all turns without gaps.
2.4. The vertices of the turns of the spirals, when the mesh is stretched, must lie in the same plane.
(Revised edition, Rev. No. 2).
2.5. The ends of the spirals on both sides of the mesh must be cut off and each end at the junction must be bent to its own spiral.
2.6. Grids after production are rolled up into rolls. The roll must consist of one piece of mesh with a length of at least 5 m for meshes Nos. 5-60 and at least 3 m for meshes Nos. 80, 100.
It is allowed to roll rolls from two pieces sewn in a spiral.
For nets of the 1st group, the roll must consist of one piece with a length of at least 10 m for nets No. 5-60 and at least 5 m for nets No. 80, 100.
(Changed edition, Rev. No. 1, 2).
2.7. The mass of the roll should not exceed 80 kg. For nets No. 80 and 100, it is allowed to increase the mass of the net roll up to 250 kg.
(Revised edition, Rev. No. 1).

3. ACCEPTANCE RULES

3.1. Grids are accepted in batches. The batch must consist of nets of the same number, the same width, the same material and is issued with one quality document. The quality document must contain:
trademark or name and trademark of the manufacturer;
grid symbol;
the width in millimeters and the length of the grid in meters, the total amount of the grid in square meters;
number of rolls per lot.
(Revised edition, Rev. No. 1).
3.2. To check the quality of the weave, the bending of the ends of the spiral, the arithmetic mean of the size of the side of the cell in the light, the length, width of the mesh and the angle of the cell, 5% of the rolls are selected from the batch, but not less than two.
(Revised edition, Rev. No. 2).
3.3. Upon receipt of unsatisfactory test results for at least one of the indicators, it is re-tested on a doubled number of rolls.
The results of the re-inspection are extended to the entire lot.
(Revised edition, Rev. No. 1).

4. TEST METHODS

4.1. The quality of the weave and the bending of the ends of the spirals are determined visually when rewinding the mesh rolls.
4.2. The arithmetic mean value of the side of the cell in the light is determined in three places of the grid, spaced from the edge by at least 100 mm, counted in two directions parallel to the sides of the cell, 10 cells for grids No. 5-15 and 5 cells for grids No. 20 -100 and measure the length of the section, including one end wire, on which the counted cells are located. The length of the section to determine the arithmetic mean value of the size of the side of the cell in the light is measured with a meter or a ruler with a division value of 1 mm.
The arithmetic mean value of the size of the side of the cell in the light (a), mm, is calculated by the formula.
