标准范围

规定了检测硫化氢的程序。可探测性的下限是1立方米气体中的4毫克硫化氢。甲基硫醇（如果存在）会在醋酸铅纸上产生过渡黄色斑点，但在不到5分钟内完全褪色。气体中存在的其他硫化物不会干扰试验。

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.
