Evropa Ittifoqining ekologik standartlari 2.0. Qo'rg'oshin (PB) tarkibi 1000pp.pm dan kam, chunki Cinkou Cinkou kam sonli C17300 ga teng, shuningdek, Cinkou C17300.Kinkou bilan birgalikda misli p17200 bilan ham etakchiliksiz Misole-Me Alloyda bepul misli pirovarde-misol. . Ushbu C17200 ning kesilishi ham yaxshi.
