Testex replica tape is used in conjunction with an analog or digital spring-loaded micrometer for acquiring surface profile measurements according to Method C in ASTM D4417. The replica tape is rubbed onto the abrasive blast cleaned surface forming a reverse replica of the peak-valley pattern in the steel. The replica is quantified using a spring-loaded micrometer to determine the maximum peak-to-valley depth. Each roll of tape contains 50 pieces.
