** Please Note:

Standards with an RSD of near or less than 5 % are certified, RSD’s of between 5 % and 15 % are Provisional, and RSD’s over 15 % are Indicated. Provisional and Indicated values cannot be used to monitor accuracy with a high degree of certainty.

1) CDN-CM-37 : Au value is “provisional” (RSD = 6.8%)
2) CDN-CGS-30 : Au value is “provisional” (RSD = 7.1%)
3) CDN-GS-1X : Ag value is “provisional” (RSD = 8.5%)
4) CDN-CM-31 : Ag value is “indicated” (RSD = 18.5%)
5) CDN-CM-32 : Ag value is “provisional” (RSD = 8.9%)
6) CDN-CM-33 : Ag value is “provisional” (RSD = 7.1%)
7) CDN-CM-37: Ag value is “provisional” (RSD = 10.5%)
8) CDN-CM-18 : Mo value is “provisional” (RSD = 6.0%)
9) CDN-CM-31 : Mo value is “provisional” (RSD = 7.3%)
