Product Description

The measurement of surface roughness is essential for precision engineering. While expensive instruments provide high accuracy, they are often unsuitable for workshop environments. This range of Surface Roughness Comparison Specimens offers an inexpensive and reliable solution for assessing machined surfaces through visual and tactile comparison.

Standard Compliance: As standardized in ISO2632-1975.

This set contains standards for the six most important machining methods in prevalent "AA" values. These blocks are used to compare and determine surface finish degree by eye estimation or magnifying glass. The contrast blocks are manufactured from 45 super carbon steel, ensuring durability and consistent reference quality. All 30 specimens are calibrated in μ"AA" (arithmetic average) and metric Ra equivalents.
