That may be a good starting point for a blank grade. Click to expand... We currently use rocklabs products, But IF a customer submits his own blank, What is the acceptable grade?

J JonSnow New Member Dec 1, 2009 #5 Dec 1, 2009 #5 I welcome customers to supply blanks and or standard reference materiel if they wish. My only requirement is that is certified. http://www.cdnlabs.com/Certificates/CDN ... ficate.pdf This SRM has recommended values of <0.01g/t in Au,Pt,Pd Notice, that the round robin is made up of 10 major labs Last edited by a moderator: Nov 21, 2013
