DZ/T 0064.86-2021Groundwater analysis methods - Part 86: Determination of cyanide. Flow injection on-line distillation method (English PDF)

1 Foreword

DZ/T 0064.86-2021 is issued by Ministry of Natural Resources.

It is one of 13 parts of the DZ/T 0064 series.

The DZ/T prefix marks a recommended standard. It is not law in itself: it becomes binding when a contract names it, when a regulation or a mandatory standard refers to it, or when a producer declares conformity with it.
