This International Standard specifies a methylene blue
spectrophotometric method for the determination of
sulfur in steel and iron.
The method is applicable to sulfur contents between
0,000 3 % (m/m) and 0,010 % (m/m). However,
niobium, silicon, tantalum and titanium interfere in the
determination of sulfur. 86
Depending on the concentration of the interfering el-
ements, the application ranges and test portion
masses given in table 1 apply.
