INFORMATION DATA

REFERENCE NORMATIVE AND TECHNICAL DOCUMENTS

________________
* On the territory of the Russian Federation there are GOST 6674.2−96 and GOST 6674.3−96, respectively. Here and further. — Note the manufacturer’s database.


This standard applies to copper-phosphorous alloys used in the manufacture of alloys of non-ferrous metals and products from them, manufactured for the needs of national economy and for export.

1. Technical requirements

1.1. Copper-phosphorous alloys are manufactured in accordance with the requirements of this standard technological instruction, duly approved.

1.2. Brand and chemical composition of the copper-phosphorous alloys shall be as specified in the table.


Table

1.3. Mass fraction of bismuth, antimony and iron is determined by the requirement of the user.

1.4. The alloy grade MF10 is made out of copper according to the GOST 859* with a mass fraction of copper not less than 99.9% and the technical red phosphorus according to GOST 8655.
______________
* On the territory of the Russian Federation GOST 859−2001. — Note the manufacturer’s database.

1.5. The alloys manufactured in the form of tiles overall size (370±10)(215±10)(30±5) mm.

Tiles separated by intersecting 40 a share.

Bays some intersecting on certain tiles (up to 10% of the tiles in the game) are not a sign of rejection.

1.6. By agreement with the consumer allowed the production of alloys in the form of strips (tapes) in the thickness from 0.3 mm to 1.2 mm bars and on the agreed dimensions.

1.7. The tile surface must not have foreign inclusions.

1.8. The metal in the fracture of the tiles must have a uniform structure and should not contain slag and other foreign inclusions.

Example of symbols tiles from alloy grade MF9:

ПлМФ9 GOST 4515−93

2. Acceptance rules

2.1. The alloys present to the acceptance of the parties. The party should consist of tiles (strips) of the same grade alloy and melting the same.

The presence of fractional parts of tiles (up to 10% of the batch weight) is not a rejection symptom.

The results of the acceptance tests reflected in the accompanying document about the product quality, which indicate:

trademark or the name and trademark of manufacturer;

grade;

the weight of the batch;

the room melt;

batch number;

the results of chemical analysis;

the designation of this standard.

2.2. Control of surface quality is performed on all or at least twenty tiles away from the party.

2.3. To control chemical composition, size and quality of the break taken at least three tiles (strips) from the party.

To control the chemical composition of the manufacturer is permitted sampling from each ladle of liquid metal.

2.4. If unsatisfactory test results of at least one indicator thereon, a second test of the doubled sample taken from the same batch.

The results of repeated tests apply to the entire party.

3. Test methods

3.1. Quality control of the surface of the fracture and the mass of individual tile (strip bar) is carried out visually.

3.2. Size control is carried out universal measuring tool according to GOST 166 and GOST 427.

3.3. To determine the chemical composition of each selected tile, a sample is taken by drilling with subsequent grinding; from each selected thin strip (tape) — chopping.

Drilling is performed by drill diameter 10−20 mm, without lubricant, with minimum possible speed, in five points: in the middle and four points on the diagonal on the distance to the diagonal from the corner. Designated entry and exit of the drill is pre-cleaned to a depth of not less than 0.5 mm.

The resulting merged sample is treated with magnet mix and, if necessary, cut and used for chemical analysis.

3.4. Chemical composition is determined by GOST 6674.1* — GOST 6674.4*. Allowed to use other methods of determining the chemical composition, if they are not inferior to the accuracy specified in the standard.
________________
* On the territory of the Russian Federation GOST 6674.1−96 and GOST 6674.4−96, respectively. Here and further. — Note the manufacturer’s database.

If there is disagreement in the assessment of the chemical composition determination is carried out according to GOST 6674.1 — GOST 6674.4.

4. Marking, packaging, transportation and storage

4.1. Each tile shall be marked:

trademark or the name and trademark of manufacturer;

the room melt;

the color coding.

4.2. The color marking is applied indelibly the entire length of the tile and equity units in the form of bands for grades:

MF10 — white (for export only);

MF9 — black.

4.3. Tiles transporterowych by all kinds of transport in covered vehicles in accordance with cargo carriage regulations applicable to transport of each type.

4.4. Storage is carried out in closed rooms in conditions excluding ingress of moisture.

4.5. Tiles transportyour transport packets in accordance with the requirements of GOST 21399 and GOST 24597 or means as agreed with the consumer. The package should consist of tiles (bars, rods) of one brand and one bathing suit. The absence of a trademark on certain tiles in the package is not a rejection symptom.

Weight and dimensions of the package must meet the requirements of GOST 24597.

Packages tied with steel strips, packing tape according to GOST 3560, strained and stapled to the castle. The free end of the strip in the belt is cut at an angle of 90 °. The length of the free end after cutting must not exceed 50 mm.

Allowed to use other means to bond the tiles in packages that meet the requirements of GOST 21650.

On the side of the package to the uld wire with diameter not less than 1.5 mm is attached a metal or wooden label transport marking under GOST 14192.

Export tiles transporterowych Packed according to GOST 24634 in boxes type III according to GOST 2991.

4.6. Tape (strip) Packed in wooden boxes according to GOST 2991, each of which put a document according to the requirements of section 2.1 and each of which is glued tag where you indicate:

trademark of the manufacturer;

the symbol of the alloy;

batch number;

the designation of this standard.
