NRMCA has released a checklist and power point presentation titled Code and Standards Requirements for Acceptance Testing developed by the NRMCA Research Engineering and Standards Committee with assistance from the Colorado Ready Mixed Concrete Association. More specifically, the presentation provides code and standard requirements on the following:
1. Purpose of acceptance testing
2. Differentiate between standard and field curing
3. Qualification requirements for third-party testing labs and lab and field testing technicians 
4. Distribution of test reports
5. Initial curing requirements for standard cured cylinders for acceptance testing
6. Effect of non-standard testing on concrete strength
7. Responsibilities related to initial curing
8. Reporting of initial curing data
9. Calculating testing variation by test data analysis
10. Criteria for core tests and establishing responsibility for low strength evaluations

The presentation is provided with notes. Ready mixed concrete industry personnel, testing labs, and architect and engineers can use this presentation as part of local seminars to help ensure that the acceptance testing conforms to industry codes and standards. The checklist can be used as a handout with the presentation and can also be used as part of pre-construction meetings and mixture submittals. TIP 16 on Evaluating Strength Test Results will also be provided and can be used as handout with the presentation. The presentation is available by contacting the undersigned.

For more information or for your copy of the presentation and handouts, contact Karthik Obla at or 240-485-1163 or Colin Lobo at
