Correct.
The code text reads: 'When the total volume of a given class of concrete is less than 50 cubic yards (38 meters cubed ), strength tests are not required when evidence of satisfactory strength is submitted to and approved by the building official.' The 100 yd cubed, 150 yd cubed and 25 yd cubed figures do not appear in the provision; the threshold is 50 yd cubed, and it applies only with the building official's approval.
