A second batch of tantalum pentoxide foil reference material has been produced in an identical manner to that of the first batch known as CRM 261. As the batch was not completely homogeneous it has been subdivided, samples of sub-batch 1 are given the code number 261R and samples of sub-batch 2 are given the code number 261S. This addendum to the certification report of CRM 261 describes the production and certification of samples of CRM 261R and CRM 261S.
