Sentence examples for a roughness value of from inspiring English sources

Since toothpaste manufacturers change the composition of the toothpastes on a regular basis also regarding the abrasive part and since the RDA value is the only measurement of abrasivity that is being tested, it is important to measure also a roughness value of the abraded material.
