The determination of the low levels of oxygen in OFMC Copper poses particular problems for industry. In 1978, the BCR has certified a reference material (CRM 054) with approx. 1 ug/g oxygen in copper. This material has become exhausted in 1986 which shows that this CRM still responds to a need of industry. The BCR has therefore undertaken the certification of a replacement material.
The certification of the replacement material (CRM 054R) was certified as (0.47 +/- 0.04) ug/g
Certification report : EUR 12240 (1989)
