This document specifies the determination of nickel-59 and nickel-63 (59Ni and 63Ni) activity concentration in samples of all types of water using inductively coupled plasma mass spectrometry (ICP-MS). Using currently available ICP-MS, this test method can measure 59Ni activity concentrations of 300 mBq⋅l−1 and 63Ni activity concentrations of 200 Bq⋅l−1. These values can be achieved with a sample…

This document is focused on the management of the round robin study (RRS) and can provide guidance for the scope development, planning, and execution of the RRS study. It can provide guidance to identify the feedstock, machine operations, process controls, and post-processing operations prior to running the study. RR organizers can identify controlled and free parameters in the study. This…
