This Japanese Industrial Standard specifies the performance of an automatic total ni"
trogen analyzer (hereafter referred to as "measuring instrument") for performing the
automatic meter reading of the total nitrogen concentration in water and its test method.
NOTE : Though this Standard specifies the performance of a measuring in-
strument and its test method, it is not intended for assessing the con"
formity of any instrument -- the performance specifications given in
this Standard are solely for the purpose of measurement of specific
target samples.
