Notes 1 In the complexly alloyed brass grades except LAN59−3-2, L75mk, LA77−2U, is allowed the mass fraction of Nickel up to 0.5%, which is not included in the total amount of other elements, and is counted as the mass fraction of copper. 2 In brass brand Lmc58−2 at the customer’s request mass fraction of manganese is set in the range of 3.0%-4,0%. 3 In brass LKBO62−0,2−0,04−0,5 mass fraction of boron content should be within the range of 0.03% to 0.10%, which does not include the amount of other elements. 4 In brass brand LA77−2U mass fraction of iron less than 0.03% is not a rejection symptom. 5 In brass brand Lamsh77−2-0,04 total mass fraction of phosphorus and arsenic should not be more than 0.04%. 6 Manufacturer of brass stamps Lomsh70−1-0,04 permitted without the mass fraction of arsenic. 7 the Calculated density is specified to calculate the reference theoretical mass of products. 8 the «— «Sign affixed simultaneously to the upper and lower limits of the mass fraction of the element indicates that this element is not specified and is determined only by specified in the order the request of the consumer, and in this case, the content of this element is included in the total of other elements. 9 Impurities that are not specified in the table take into account in the total amount of other elements, the list of which is determined by agreement between the consumer and the manufacturer. The admixture should be considered as the element from which specified only a maximum limit to its content.

(Changed edition, Rev. N 1).

2.2 Requirements for physical and mechanical properties of brass set in the standards for specific types of products and (or) by agreement (contract) between the consumer and the manufacturer.

2.3 Chemical composition of brass depending on the grades determined according to GOST 1652.1 — 1652.13 GOST, GOST 9716.1 — 9716.3 GOST, GOST 24978, GOST 25086.

Allowed to use other methods of analysis, accuracy is not inferior to the above.

Arbitration methods of analysis point in the standards for specific types of products.

2.4 the results of the analysis of each element are rounded according to the rounding rules established ST SEV 543, to the number of characters provided for by tables 1, 2 and 3.

If there are differences in the analysis results determined with the accuracy specified in the arbitration method of measurements.
