4.1.1. The tensile strength of abrasive paper in a wet state is determined as follows: prepared samples of abrasive paper are soaked in water at a temperature of (20±2) °C for two hours before testing. Excess water is removed with filter paper and immediately tested according to GOST 6456-82.

4.2. The method for determining the cutting ability of abrasive paper is in accordance with GOST 6456-82 with the additions specified in paragraphs 4.2.1, 4.2.2.

4.2.1. Before testing, sandpaper samples are subjected to drying for one hour at a temperature of (100±5) °C.

4.2.2. The cutting ability of the sanding paper is determined by:
clamping force - 25.5 N;
grinding time - 5 min.
Testing of 16-M40 grit sandpaper is carried out with air blowing.
The limit of permissible error in weighing samples of organic glass plates when testing sandpaper with grain sizes M63-M14 is ±0.001 g.

4.3. Control of dimensions, uneven thickness, appearance of the working surface of the sanding paper - in accordance with GOST 6456-82.

5. LABELING, PACKAGING, TRANSPORTATION AND STORAGE

5.1. On the non-working surface of the roll of abrasive paper, every (150±15) mm in the longitudinal and transverse directions the following must be applied:
manufacturer's trademark;
symbol;
batch number.
Note. By agreement with the consumer, the dimensions of the roll or sheet may not be applied.

(Changed edition, Amendment No. 1, 3).

5.2. Winding the sanding paper into rolls should be tight and even, preventing the formation of wrinkles, folds and crumpled areas.
The end surface must be smooth, the protrusions of the edges must not exceed 10 mm.

5.3. Each roll of sanding paper must be wrapped in paper in accordance with GOST 8273-75, GOST 18277-72, GOST 10127-75 or GOST 2228-81 and sealed at the joint. Layers of packaging paper must reliably cover the ends of the roll and ensure its safety during transportation.

5.4. Sanding sheets should be packed in packs of (50±1) pieces. or (100±2) pcs. The packs are sealed with paper or paper sanding tape with a grain size of 10 and finer, with a width of at least 35 mm across the width of the sheets.
(Changed edition, Amendment No. 1).

5.5. Packs of 5-10 pcs. placed in bags and sealed with paper or paper sanding tape with a grain size of 10 and finer, at least 35 mm wide, or with adhesive tape grade B according to GOST 18251-87. The sealed bag must be wrapped in paper in accordance with GOST 8273-75, GOST 18277-72, GOST 10127-75 or GOST 2228-81 so that its end is on the front side of the bag. The package is tied with twine.
(Changed edition, Amendment No. 1, 2).

5.6. (Deleted, Amendment No. 3).

5.7. Each packaged roll or bag must be affixed with storage instructions and a label indicating:
manufacturer's trademark;
batch numbers;
release dates;
symbol;
number of sheets for the package;
images of the state Quality Mark for sanding paper, which has been assigned the state Quality Mark in the prescribed manner;
technical control stamp.
The label must be stuck on the roll at the joint of the packaging paper.

5.8-5.19. (Excluded, Amendment No. 3).

5.20. Other requirements for labeling and packaging, as well as transportation and storage, are in accordance with GOST 27595-88.
