(Introduced additionally, Rev. No. 4).

4. TEST METHODS

4.1. The main overall dimensions of tins are measured 10-15 minutes after they are filled with air.

The outside diameter and profile width are measured with a tire mounted on the appropriate rim, at an internal pressure corresponding to the maximum load capacity of the tire.

The profile width is measured along the smooth (without inscription and decorative protrusions) surface of the sidewall. Measurements are performed with a caliper according to GOST 166-89 in five sections equally spaced along the circumference.

The outer diameter is calculated from the circumference measured along the center line of the tire tread with a metal tape measure in accordance with GOST 7502-89.

The chamber is measured after complete removal of air from it.

The measurement errors of the chamber and rim tape thicknesses should not exceed 0.05 mm, the errors of other measurements should not exceed 0.5 mm.

4.2. The appearance of the tires is evaluated visually.

4.3. The tightness of the chambers is determined by the complete immersion of the air-filled chamber in water, while no air bubbles should be released from the chamber.

It is allowed to check the tightness by holding the chambers filled with air for 24 hours, while the chambers must retain their original appearance.

4.4. Conditional tensile strength and relative elongation at break of the rubber used for the manufacture of the tread is determined according to GOST 270-75 (sample type I or II).

4.5. Abrasion is determined according to GOST 12251-77 with a friction force of 30.0 ± 2.5 N (3.00 + 0.25 kgf) for black rubbers; (23.5 ± 1.5) N (2.35 + 0.15 kgf) for colored rubbers.

4.6. The Shore A hardness of the rubber used to make the tread is determined according to GOST 263-75.

4.7. To determine the bond strength when the tread is peeled from the carcass in the longitudinal direction, two samples are cut along the tread tread (one of two diametrically

opposite places of the circumference of the tire) with a width of (25.0 ± 1.0) mm and a length of 100-150 mm. At one end of the sample, the protector is first peeled off from the frame in a section 30-50 mm long to fix them in the clamps of the machine.

Tests are carried out on a sample section 50-60 mm long according to GOST 6768-75 at a moving clamp speed of (100 + 10) mm/min.

The exposure time before testing products after vulcanization is at least 6 hours, samples - at least 2 hours.

4.8. To determine the conditional tensile strength and relative elongation at break, the chambers are cut from any place in the chamber in the longitudinal direction of at least five samples.

Colored and two-color tires are transported packed in fabric, paper or film made of polymeric materials.

It is allowed, in agreement with the consumer, to send colored and two-color tires without

packaging.

METHOD FOR DETERMINING THE COEFFICIENT OF EASY RIDE

The ease of running coefficient of a tire is defined as the ratio of useful work to the work expended to overcome the rolling friction force of a tire on a smooth drum.

1. Hardware

1.1 Stand for determining the coefficient of ease of movement of tires

The scheme of the stand is shown in the drawing

2. Tire preparation for testing

2.1. The tire and chamber after vulcanization must be kept at a temperature of (25 ± 2.5) ° C for at least 5 days

2 2 Before installation, the tire and the tube must be kept in the test station for 12 hours at a temperature of (25 ± 5) ° C

2 3 The tire must be mounted on a pre-centered rim with radial and lateral runout of ±1.0 mm

2 4 The tire and rim assembly must be mounted on a special fork of the test stand

3. Testing

3 1 The metal rim shall be fixed in the fork of the test stand and pressed against the metal drum of the stand with a force (R) equal to

(45±0.5) kg - for all tires;

(30±0.5) kg - for tires for teenage bikes

3 2 The rim assembly with the tire is brought into contact with the middle of the treadmill of the drum The stopper is removed, while the tire must be pressed against the drum with force F Wind the thread with weights on the pulley by hand and raise them to position I (see drawing)

The system of weights is released from position I to fall freely, while it is necessary to pick up the load qb so that after splitting off the load q (position II) the load I returns to position IV

The load q\ selected in this way is weighed on scales of the type RP-15Shch or VNTs-20 according to TU 25 06 2068

3 3 Load q is determined according to item 3 2, while the test tire is mounted on the rim.

3.4. The tire running lightness factor (14) is determined by the formula

1-shia on the rim, 2-weights, 3-drum
