REPRINTING.

AMENDED, published in the IUS N 8, 1988

An amendment made by the manufacturer of the database

This standard applies to castings obtained by any method of unalloyed and alloyed cast iron with lamellar, compacted or spheroidal graphite and malleable cast iron.

Established by this standard indicators of technical level are provided for highest and first quality categories.

1. TECHNICAL REQUIREMENTS

1.1. Cast iron castings shall conform to the requirements of this standard, GOST 1215−79, GOST 1412−85 and GOST 1585−85, GOST 7769−82, GOST 7293−85.

1.2. The configuration of castings and grade of cast iron shall meet the requirements of detail drawing, designed according to GOST 3.1125−88.

1.3. Maximum deviations in sizes and weight, as well as machining allowances — as per GOST 26645−85*.
________________
* On the territory of the Russian Federation the document is not valid. Valid GOST R 53464−2009, here and hereafter. — Note the manufacturer’s database.

Forming a slope in accordance with the configuration of the casting appoint GOST 3212−92. The tolerance of the straightness of flat surfaces should be no more than 2/600.

1.4. Casting must be cleaned of sand and metal penetration.

Bays, growths, veining, profit and sprues must be removed in any way. Extraction of bays, growths, veining, profit and sprues must be stripped in accordance with the requirements of the casting drawing.

1.5. Castings should not have defects which deteriorate their appearance. Slight defects may be allowed in accordance with GOST 19200−80 within the allowance for machining.

1.6. Depending on the purpose of details in drawings or in specifications for concrete casting in agreement with the consumer allowed to define and standardize additional technological and operational properties in accordance with GOST 4.439−86 and the application of this standard.

(Amendment. ICS N 8−1988).

2. ACCEPTANCE RULES

2.1. To control the conformity of the castings to the requirements of this standard, the manufacturer conducts acceptance testing and periodic testing.

2.2. Castings take parties. The party should consist of castings of one grade of cast iron, one obtained by melting in furnaces of periodic action or in the course of one shift in conditions of steady cupola or the duplex process at constant charge held a joint heat treatment and furnished by a single document about quality that contains the following data:

trademark or name of the manufacturer and his address;

the drawing number and the name of the casting;

the batch number or melting, the volume of the party;

brand of cast iron and the designation of the standard;

test results and quality control Department stamp.

2.3. Compliance appearance drawing according to the PP.1.2, 1.4 put every casting batch.

2.4. The compliance of the properties characterizing the brand of cast iron, done by a lot of castings according to the norms of the state standards for a particular grade of cast iron.

2.5. The size of the casting and weight checked at periodic tests. Plan and control the scope of selection of the party set THAT in concrete casting.

2.6. The periodicity, sample size and rules for the control of additional properties are performing according to standards for specific products and in their absence on the other.

2.7. If unsatisfactory test results of at least one of the indicators, repeat tests are carried out at twice the sample. Allowed results are unsatisfactory re-testing to establish total control of casting. Casting after you correct the mismatch of properties, structures or defects are allowed to be resubmitted for acceptance.

3. TEST METHODS

3.1. The surface condition of casting is checked visually.

3.2. The size and weight of castings according to GOST 26645−85 check of the measuring tool and devices.

3.3. Quality inspection of castings and grade of cast iron is performed in accordance with the requirements of this standard, GOST 1215−79, GOST 1412−85 and GOST 1585−85, GOST 7293−85, GOST 7769−82.

3.4. Test properties, certain additional requirements of the drawing or specifications, perform according to applicable standards, and in the absence — according to the methods agreed between the manufacturer and the consumer.

4. MARKING, PACKAGING, TRANSPORTATION AND STORAGE

4.1. The casting provide a label with the marking stamps of iron and an indication of the number and weight of the castings in the batch.

4.2. Transportation marking is performed according to GOST 14192−96 and the order of foreign trade organizations with application of manipulation signs top, the size and weight of the individual packages.

4.3. Cast iron castings, if necessary, specified in the one Packed in boxes according to GOST 2991−85 or GOST 10198−91. The drawer type is selected depending on the dimensions and weight of castings specified in the SPECIFICATIONS.

The size of the boxes and placing them on a pallet must comply with GOST 21140−88.

4.3.1. Castings of high silicon cast iron under the package should be moved wood chips or rigid struts.

4.4. Casting transporterowych all kinds of transport in accordance with the rules of loading, lashing, carriage, valid for this mode of transport.

4.4.1. Formation of the transport package pointing to THAT and is produced by NTD.

4.4.2. Overall dimensions and gross weight of overpack — GOST 24597−81.

4.5. The conditions of preservation and storage indicate THAT for specific castings and shall meet the requirements of the GOST 9.014−78, GOST 15150−69.

AN EXAMPLE OF CALCULATING THE LEVEL REQUIREMENTS FOR CASTING

1. The level of basic and additional requirements (UT) expressed as a percentage of the amount of premiums or discounts on their performance in a certain price 25−01−81, 07−01−80 or 08−01−80 assigned to the base price of one ton of iron casting of a suitable type and casting method. UT is defined by the manufacturer and reflected in the routing.

2. In the appointment of additional requirements not covered by the price lists 07−01−80, 08−01−80, premium or discount is adjusted in accordance with the price list 25−01−81.
