If CTM is used, are current certification copies of laboratory (TL) and acceptance testers (TL ) present 5a. If AASHTO is used, are current copies of laboratory's certification and acceptance testers's present. 5b. If ASTM is used, Independent Assurance Sampling and Testing (IAST) is required by another entity. 6. The Statewide Independent Assurance Database (SIAD) is a web application developed by the California Department of Transportation, Materials Engineering Testing Services (METS) to allow IA staff the ability to easily submit tester and laboratory information into Caltrans' database via the internet. The SIAD serves as a central repository for statewide Independent Assurance (IA) data pertaining to IA .

Obtaining Accreditation. Ensure that your laboratory's practices and quality management system (QMS) meet the requirements of the AASHTO Accreditation Procedure Manual, AASHTO R 18, and any other ASTM quality system specifications that you may need to comply with such as C, D, D, and E; Schedule an assessment with AASHTO re:source for asphalt binder, emulsified asphalt, hot. Included in the Appendixes/Lab Accreditation Manual is a list of Tulare County testing capabilities, Equipment List with related Calibration, also Test Frequencies that may be used for acceptance testing (all tabbed). Independent Assurance Program (IAP) IAP shall be provided by Caltrans, the Agency's certified materials laboratory, or. Autumnvale Drive, Unit E. San Jose. 4.

Verification of lab qualifications for the applicable materials on this project (e.g. ISO for steel, and AASHTO Accreditation Program (AAP) for concrete). Provide a list of verification tests to be performed by the implementing agency along with the frequency and applicable industry standards to be used/specified (ASTM, CTM, etc.). Caltrans IA Manual. This manual is basically the bible for getting your laboratory and technicians certified by Caltrans. If you have a laboratory, whether you are already certified or not, I would recommend that you read through this as it gives you a lot of insight into what to expect from the state and how to prepare for their visit.
