标准摘要
[中文适用范围]： 规定了检测硫化氢的程序。 可检测的下限为 1 m 气体中 4 mg 硫化氢。 甲硫醇（如果存在）会在醋酸铅纸上产生晶体管状黄色污点，但会在 5 分钟内完全褪色。 气体中存在的其他硫化合物不会干扰测试。 [外文原描述]： Specifies a procedure for the detection of hydrogen sulfide. The lower limit of detectability is 4 mg of hydrogen sulfide in 1 m^3 of gas. Methyl mercaptan, if present, produces a transistory yellow stain on the lead acetate paper which, however, fades completely in less than 5 min. Other sulfur compounds present in the gas do not interfere with the test.
