JIS K 0170-2:2011 PDF

Scope: This Standard specifies the method of determination for the nitrite nitrogen and nitrate nitrogen contained in industrial water,industrial wastewater,etc. by using the flow analysis according to absorption spectrophotometry. The method is also applicable to surface water, ground water, seepage water, etc.
