TQC Rugotest

TQC Rugotest No. 3 is Comparison standard for blasted surfaces, consisting of both 6 examples of grit-blasting and also shot-blasting. The method complies with ASTM D 4417/A, and also supplied with a case.

Surface finish specimens for testing surface roughness by the sight and touch method.

Rugotest kit is come with:

  • high quality metal reference plate with table in grit and shot scale in N6 –  N11.
  • Manual book.
  • Sturdy leather pouch.

Registered design L.C.A. – C.E.A.

The Sight and Touch method

The assembled specimens is to represent, for the most commonly-used machining methods. The limiting values of surface finish quality arranged in a geometrical progression in accordance with factor 2.

These among chosen value recommended for the criterion “Ra” in the both ISO standards 2632/I-1975 and 2632/II-1977.

Experience shows that the method of comparing a machined surface with a known sample, by sight and touch. Enables the quality of the finish of this surface to be estimated with remarkable accuracy.

The remotest method is particularly convenient when specifying surface finish for components which feature in sub-contracting arrangements, sales contracts, etc.

The samples supplied are for use only in sight and touch comparisons, not as references for calibrating surface finish measuring instruments of any type.

Although the Rugotest is a simple and inexpensive tool, the reliability of the results it provides makes it highly useful at the levels of any manufacturing industry.

When opened, the left-hand page gives the most important information for the design office, the workshop and the classroom, as well as a summary of the relevant ISO standards for surface finish and the graph showing the relationship between production cost and surface finish.


Surface roughness comparison standard, model RUG 3 for shot- and grit blasting.
Material : High-nickel test plate
Width : 90mm
Length : 118mm


Complies with standards NF/E05-051, ASTM D 4417/A, ISO 2632 / I 1975, ISO 2632/II 1977. Look up the appropriate standard for a correct execution of the test.


Use direction:

Only by positioning the comparing standard onto the test surfaces, a comparison to the reference examples of the standard is made. Assess the profile of the comparison standard most closely to match that of the test area and determine the result to the class: A for Shot and B for Grit. The fineness of the abrasive medium is further divided into A for coarse grain or B for fine grain. Comparison of average roughness Ra value is found in the table N6 – N11.
