6 acceptance Rules

6.1 General rules for the acceptance of rails — according to GOST 7566.

6.2 the parties accept the Rails. A party is considered one of melting rails, of the same type and accompanied by a quality document certifying the compliance of rails the requirements of this standard and containing:

is the name or symbol of the manufacturer;

— rail type;

— grade of steel;

— number of rails with their length and weight;

— date of issuance of the document of quality;

— the number of the wagon or other vehicle;

— the name and address of the buyer;

— order number (contract).

The document about quality should be signed by the technical control service of the manufacturer.

The acceptance of rails conducted by the office of technical control of the manufacturer. Acceptance is performed according to the results of the acceptance inspection including acceptance tests and continuous monitoring.

6.3 Control of dimensions and surface quality is carried out on each rail.

6.4 acceptance testing of rails is carried out for each heat. The quality control of rails taken:

one Causeway a sample for analysis of the chemical composition of the steel;

— one sample from one rail or trim — to determine of mechanical properties of rails by tensile test and hardness on the running surface of the head.

In the control placenow taken one sample from one rail of each of the fifth heat.

Mechanical properties and hardness of the rails is provided by the steel chemical composition and manufacturing technology of rails and at a total mass fraction of carbon and one-fourth of the mass fraction of manganese (C+¼ Mn) of at least 0.72 percent are not subject to control. Determination of mechanical properties and hardness of the rails in this case is carried out at the request of the consumer.

The templates should be calibrated in the prescribed manner and conform to precision rolling of rails of a certain type.

7.3 the Length of the rails measure metal measuring tape according to GOST 7502 or other means to ensure the required measurement accuracy.

7.4 General the curvature of the rails evaluated visually in the «standing on the sole».

If necessary, the total curvature of the rails is calculated by the amount of deflection of which is measured by the maximum gap between the rail surface and the steel string stretched between its ends.

7.5 Determination of deviations from straightness of the rails is carried out by the largest gap between the rail surface and the reference line (chord or tangent).

7.6 the twist of the rails is determined at the end of the rail in the position «standing on the soles» the magnitude of the maximum clearance measured with a feeler gauge, between the surface control rack and the base of the foot rail.

7.7 surface Quality of rails checked visually.

7.8 the Bundle at the ends of the rails controlled trial logging of chips, a split which is considered a sign of stratification.

7.9 Determination of mechanical properties of rails when a tensile test is carried out according to GOST 1497 on cylindrical samples of initial diameter 6 mm and the initial estimated length of 30 mm Sample is cut from the top of the head in the area of the fillet as close as possible to the surface.
