Correct answer is:
  • (A)  Sound or ring Test
Explanation:
According to OSHA, an abrasive wheel must be sound- or ring-tested for cracks and defects before it is mounted. To test the wheel, one should tap the wheel lightly with a nimble, non-metallic instrument. If the wheel sounds dead or cracked, it should not be used, as it can break apart during operation. If a “ring” or clear metallic tone is heard, it means that the wheel is undamaged.
