ASTM C31 Standard Practice for Making and Curing Concrete Test Specimens in the Field ACI Concrete Field Testing Technician Level 1. Michigan Concrete Association
Molds used for test specimens should be placed on a level, rigid surface, free of vibration and other disturbances! A flexible table or tailgate of a truck are not acceptable places to mold test cylinders per ASTM C31.
