Scope
GB/T 38216.7-2026 is the English-translated version of 钢渣 碳和硫含量的测定.
GB/T 38216.7 specifies how carbon and sulfur are determined in steel slag, and it is Part 7 of the Chinese series on steel slag analysis. Steel slag is produced by the hundred million tonnes a year in China and is no longer treated as waste: it goes into cement, road base and aggregate, and its acceptance for those uses depends on knowing what is in it. Carbon and sulfur matter because they affect the stability and the environmental behaviour of the material once it is bound into concrete or laid under a road. The document fixes the sample preparation, the determination method and the precision expected, so that a figure from one laboratory can be compared with another. For a slag processor or a cement plant buying it, this is the method a Chinese acceptance test refers to.
