TEST REPORT
Object: Keofitt Sampling Valves (VALVE BODY M4 TYPE T)Material identification: W1.4404, Charge no. 438074Performed for: Keofitt A/S Industrivænget 6-8
DK-5700 Svendborg
MEASUREMENT INSTRUMENT
Roughness meter: Diavite DH-8Calibrated against: Test plate 528 PE5ALast calibrated: 30-01-2015
TEST PROCEDURE
Using a roughness meter with absolute stylus KEOFITT partner Søby CNC A/S, Sneppevang 1, DK-3450 Allerød, has performedsurface roughness measurement of the process connection measurements of the process connection and of inside surfaces in thevalve chamber and in-/outlets. Results are given in the table below.The area to be measured is aligned with respect to the instrument’s straight guide. 4 longitudinal scans are performed, labelled 1 - 4(see sketch below). 2,0 mm is scanned, corresponding to the test length of 1,5 mm and a filter with a cut-off of 0,25 mm. The stylusused has a rounding radius of approx. 2m.
