3. ACCEPTANCE RULES

3.1. The mesh is accepted by the parties. The party should consist of grids of the same rooms, same width, same material and decorated by one document on quality. The document about quality should contain:

is the trademark or name and trademark of manufacturer;

— the symbol grid;

— the width in millimeters and the length of grid in meters, the total number of mesh in square meters;

— number of rolls in the party.

(Changed edition, Rev. N 1).

3.2. To check the quality of the weave, turning end of the spiral, the average value of the width of the cell in the light, length, mesh width and angle of the cell from the party take 5% rolls, but at least two.

(Changed edition, Rev. N 2).

3.3. If unsatisfactory validation results of at least one of the indicators, it conducted a re-verification at twice the number of rolls.

The results of re-examination extends to the whole party.

(Changed edition, Rev. N 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 rolls of mesh.

4.2. The arithmetic average of the width of the cell in the light is determined at three places of the grid distant from the edges of not less than 100 mm, counting in two directions parallel to the sides of the cell to 10 cells for the grids NN 5−15 and five cells for the mesh and 20−100 NN measure the length of the plot, including one extreme wire, which is counted cells. The length of the site to determine the average value of the width of the cell in the light measuring meter or a ruler with a scale division of 1 mm.

The arithmetic average of the width of the cell in light (), mm, is calculated by the formula

,

where  — the length of the plot on which are arranged successively measured in the respective directions five or 10 cells, mm.

 — the number of counted cells.

 — nominal wire diameter, mm.

The final value of the arithmetic mean size of the cell under light is defined as the arithmetic mean of six measurements.

4.3. Wire diameter is measured with a micrometer according to GOST 6507 before the production of the grid.

(Changed edition, Rev. N 2).

4.4. The width of the mesh measured at the exposed angled ends of the wires with a meter or a tape measure with a scale division of 1 mm. Length of the mesh measured under tension, eliminating the change in shape of the cells, a meter or a tape measure with a scale division of 1 mm, or counter.

4.5. The corner of the cell to check a protractor according to GOST 5378 or template in three places of the grid, but not closer than two cells from the edge of the grid.
