ACI Concrete Strength Testing Technician Practice Test

Which of the following statements about the loading for calibration is true?

1. It must always be power operated

2. It can be either power or hand operated

3. It must be hand operated

4. It can only be done by a certified technician

The correct answer is: It can be either power or hand operated

The assertion that the loading for calibration can be either power or hand operated is correct because both methods are acceptable and commonly used in practice. In concrete strength testing, the method of applying the load during calibration can vary based on the type of equipment and the preferences of the testing facility. Power-operated devices tend to provide a consistent and controlled loading process, which can be beneficial for precise measurements. On the other hand, hand-operated methods can also achieve accurate results and might be more practical in certain situations, such as in field testing or where power equipment is not available. Ultimately, the flexibility to choose between these two loading methods is important for ensuring that calibration can be performed under various circumstances, reflecting common practices in the industry.
