All test data and calculations are to be recorded in Laboratory workbooks. Test results are then to be recorded through SiteManager.

==1045.6.2 Sample Record==
The sample record shall be completed in SiteManager, as described in [[:Category:101 Standard Forms#Sample Record General Information| Sample Record General Information]] [[image:bulldozer.jpg|20px]], and shall indicate acceptance, qualified acceptance, or rejection. Appropriate remarks, as described in [[106.20 Reporting|EPG 106.20 Reporting]], are to be included in the remarks to clarify conditions of acceptance or rejection. Test results shall be reported on the appropriate templates under the Tests tab.
