No terms and definitions are listed in this document.
The test piece is rotated on a vertical axis against the sliding rotation of two abrading wheels which arepressed against the test piece with a specified force.One abrading wheel rubs the test piece outwardstowards the periphery, the other inwards to the centre.Any damage to the test piece is noted alongwith any change in colour.
Abrasive wheels, tungsten carbide (“S” series,e.g.”S-35′, see Annex A), rubber-based (“CS” series,e.g.”CS-10″, see Annex A) or silicon carbide (“H” series,e.g.”H-22″, see Annex A), width (12,7± 0,1) mm,maximum diameter 51,7 mm and minimum diameter 44,0 mm.Abrasive wheels are gradually abradedaway during use. The maximum diameter of 51,7 mm is the diameter of a new wheel. Used wheelsshall be discarded when the diameter falls to 44,0 mm. The type of abrasive wheels to be used shouldbe agreed with the client and the type of wheel used reported in the test report [8 c)]. Other types ofabrasive wheels can also be used at the client’s request. The abrasive wheels used in the test should be ofthe same diameter.
Suitable apparatus for preparation and reconditioning of the rubber-based and siliconcarbide abrasive wheels and ensuring that the re-faced wheel is within the permissible unbalances ofgrinding wheels specified in lSO 6103, and that there is full surface and perpendicular contact with thetest pieces. A diamond re-facing tool is required for preparing silicon carbide abrasive wheels (Annex A).ISO 17076 pdf download.
