2 Column «Other elements» («Amount») includes all elements whose mass fraction is equal to or more than 0.01% of each of the elements individually. Other elements are not defined, but are guaranteed by the manufacturer of ligatures.

3 In ligatures, except for ligature AIZr10 (B), the maximum content of tin should not exceed 0.02%.

4 The manufacturer guarantees in the ligatures the content of lead + cadmium Grade R 53777-2010 Aluminum alloys. Technical conditions (with Change No. 1)0.0095%, and in ligatures not doped with beryllium, the content of beryllium Grade R 53777-2010 Aluminum alloys. Technical conditions (with Change No. 1)0.0001%.


(Changed edition, Rev. N 1).

3.4. The ligatures are made in the form of wafer plates weighing not more than 10 kg or as a rod with a diameter (9.5 ± 0.5) mm wound in a coil weighing not more than 180 kg. Ligature AISc is made in the form of plates cast into a mold, followed by pruning the gate. The brand name AIMn60 is supplied in the form of flakes of 1−10 mm in size. Some ligatures, due to their metallurgical characteristics and composition, are released in the form of pieces of irregular shape or broken wafer plates.

3.5. The dimensions of the wafer plates are subject to agreement between the manufacturer and the customer of the ligatures. Recommended size of waffle plates: 440x220x50, 500x200x50 or 300x200x50 mm.

3.6 The surface of the wafer plates should be clean. On the surface are not allowed slag and other foreign inclusions visible to the naked eye. On the surface, traces of oxide coatings, traces of cutting or defacing defects are allowed.

3.7 The presence on the surface of rods and macrosections of slag and other foreign inclusions visible to the naked eye is not allowed.

3.8 Melting must be identified by the appropriate number. The shape of the samples and the conditions for their selection for chemical and spectral analyzes are determined by technological instructions of the manufacturer. Each sample must be taken from the molten metal from the furnace, the liquid stream, the cast plate or rod after the processing has been completed.

4 Acceptance rules

4.1 Ligatures are accepted in batches of mass not exceeding 1000 kg. A party must consist of products of one brand, one size, one or several swimming trunks and be issued with one quality document containing:

— the trademark or the name of the manufacturer and the trademark;

— name of the consumer;

— product brand, product type, color marking according to Appendix A;

— lot number, melting numbers;

— number of packages, their masses are net and gross;

— results of chemical analysis of each melting in the volume of the requirements of Table 1;

— the designation of this standard.

The quality document must have a stamp of the manufacturer and the signature of the head of the quality service.

4.2 At the manufacturing plant, the control of the ligatures is carried out in the following volume:

— Requirements for the quality of the surface for defects — 100%;

— lot weight — 100%;

— Marking — 100%;

— Packaging quality — 100%;

— the chemical composition of the ligature — each melting.

4.3 When obtaining unsatisfactory results of chemical and spectral analyzes, at least one of the indices for it is repeated analysis on a doubled number of samples taken from the same lot. The results of the repeated analysis are distributed to the whole lot.

4.4 Customer enterprise, the reliability of the chemical analysis of the ligatures carried out by the manufacturer determines on the selected samples — two percent of the plates, bays from the lot, but not less than on one plate, the bay of each melting.

5 Test methods

5.1 Selection, preparation of samples and storage of spare samples for determining the chemical composition of ligatures — in accordance with GOST 24231. It is allowed to select the chips for chemical analysis by the method of milling the end face of a tempertlet cut at a distance of one-fourth the length of the wafer plate.

5.2 For the determination of the chemical composition of the master alloy, manufactured in the form of a rod with a diameter of 9.5 mm, wound up in a bay, samples up to 300 mm from the bay shall be taken. Of these samples, a chip is selected on a lathe, then — in accordance with GOST 24231 .

5.3 The chemical composition of the ligatures is determined in accordance with GOST 7727, GOST 11739.2 — GOST 11739.7, GOST 11739.9, GOST 11739.11 — GOST 11739.13, GOST 11739.15 — GOST 11739.21, GOST 11739.23 — GOST 11739.25, and also according to the methods of manufacturing enterprises agreed with the consumer.

5.4. The quality of the product surface is checked by inspection without the use of magnifying devices, the mass is determined by weighing on mechanical or electronic scales that provide the necessary weighing accuracy.

5.5 For the chemical analysis of the master alloy in the form of plates, samples 20 mm thick are selected in cross section from opposite ends of the fragment.

6 Marking, packaging, transportation and storage

6.1. For each plate and bay of ligatures from two opposite ends, indelible paint shall be marked with a strip or strip of width from 10 to 15 mm each in accordance with annex A.

6.2 Each ligature plate must be marked with an indelible paint indicating the melting number. Metal marking is allowed. The height of the digits is not less than 15 mm.

6.3 The marking of the ligatures shall be marked on a label affixed to the package of the unit or bay and contain the following information:

— the trademark or the name of the manufacturer and the trademark;

— name and brand of products, product type, color marking;

— batch number;

— gross and net masses;

— results of chemical analysis of each melting within the scope of the requirements of Table 1.

6.4 Ligatures plates are delivered in batches packed in blocks on wooden pallets. Bays of ligatures in the form of a rod are supplied packed in 2−3 bays on wooden pallets. The bay is wound up with one bundle (piece) of the rod. Blocks of plates or coils of ligatures are fastened with tape to wooden pallets and packed in polyethylene film to protect against moisture ingress.

6.5 Packing plates or coils should ensure their safety during transportation and should not be destroyed during loading, reloading and storage.

6.6 Flake ligature of the brand AlMn60 is supplied in big bags with a weight of 500 or 1000 kg, attaching a label with the marking according to 6.3.

6.7 Ligatures are transported by all modes of transport in covered vehicles.

6.8 Ligatures should be stored in covered, dry rooms in conditions that prevent moisture and active chemicals from entering it.

6.9 When marking ligatures, the requirements of GOST 31340 (regarding the warning of special risks) should be taken into account.

7 Safety and environmental requirements

7.1 In the manufacture of aluminum-beryllium master alloys, the safety requirements are determined by the presence of beryllium, which, according to the degree of exposure to the body, is classified as the first hazard class in accordance with GOST 12.1.007. Air in the working area must comply with the sanitary and hygienic requirements of GOST 12.1.005 .

7.2 In the manufacture of the remaining grades of ligatures according to Table 1, the safety requirements are determined by aerosols of aluminum of predominantly fibrogenic action, which, according to the degree of exposure to the body, are classified as the third hazard according to GOST 12.1.007. Air in the working area must comply with the sanitary and hygienic requirements of GOST 12.1.005 .

7.3 According to the conditions of transportation and storage of alloys all grades are referred to the 9th hazard class of category 923 according to GOST 19433 .

8 Manufacturer’s warranty

8.1 The manufacturer confirms compliance of the ligatures with the requirements of this standard, subject to the conditions of transportation and storage.
