Surface roughness comp.shot SRC-340/ SRC-341
Common Characteristics
The SRC-340 ( G – Sand ) and SRC - 341 ( S – Wood ) models are used to estimate the surface gravel obtained after sand or coil cleaning, respectively, according to International Standard ISO 8503 and ASTM D4417. A suitable standard to be applied to the surface for visual comparison of four segments by a comparative method. For the best evaluation, it is recommended to use a magnifying glass with a seven - fold magnification and the study to be performed in good light.
