Nickel

Although these improvements are welcome, they have significant implications. The accurate analysis of solutions containing low concentrations of nickel requires the use of more sensitive equipment, such as ICP (Inductively Coupled Plasma – Optical Emission Spectrophotometry) requiring major capital investment and experienced staff.  The standard also specifies a minimum of three samples to be tested “wherever possible”, adding to both testing and stock write off costs. …

The Birmingham Assay Office has fought these unhelpful changes hard via the BSI, our voice in CEN, but the UK has been outvoted. The inevitable consequence is that some alloys which are currently nickel compliant will no longer be so. The Laboratory are undertaking extensive research, comparing data from both tests in order to understand the implications more fully. If you would like to discuss this further with Laboratory staff please call 0871 871 6020 or emailtesting@theassayoffice.co.…
