What is 1880 B about?

A unit of SRM 1880b consists of four sealed vials, each containing approximately 5 g of portland cement ground to pass through a 75 um (no. 200) sieve. Certified values for 13 constituents are reported in Table 1 as mass fractions on an as-received basis. Reference values are noncertified values that are the present best estimates of the true values. The certification is nullified if the SRM is damaged, contaminated, or otherwise modified
