    According to GOST 17711-93 and STP M354-99 the total share of impurities should be ≤ 2,20%. Impurities not specified are taken into account in the total amount of impurities. The mass fraction of nickel in brass is allowed at the expense of copper and is not included in the sum of impurities. Upon the manufacturer's agreement with the consumer, the mass fraction of lead is allowed 1.20-2.00%.
