标准范围

ISO 4496:2017规定了铁、铜、锡和青铜粉末中不溶于普通矿物酸的非金属材料近似含量的测定方法。所指的不溶性物质通常被认为是酸不溶性二氧化硅和硅酸盐、碳化物、氧化铝、粘土或其他难熔氧化物，它们存在于制造粉末的原材料中，或在制造过程中引入。

ISO 4496:2017 specifies methods for determining, in iron, copper, tin and bronze powders, the approximate content of non-metallic materials which are insoluble in the ordinary mineral acids.The insoluble matter referred to is generally considered to be acid-insoluble silica and silicates, carbides, alumina, clays or other refractory oxides which are either present in the raw material from which the powders are manufactured or introduced during the manufacturing process.
