What we check:

  • Deformation

  • Burrs
  • Cracks and Fissures
  • Corrosion or Oxidation
  • Pins and Springs
  • Moving Parts

Deformation: 

If any metal parts or metal devices are deformed in any way (compare them with the same, unused model), the product should be retired.

Abrasion:

If abrasion on any part of the product is more than 10% (compare with same, unused model), the product should be retired.

Burrs:

Burrs and other sharp edges must be filed off using a needle file. However, the maximum amount is 10% compared to a same, unused model. If the damage exceeds 10%, the product should be retired.

 

Cracks and Fissures :

If visible cracks or fissures are seen on the product or its components, the product should be retired.

 

Corrosion or oxidation:

If any metal parts or metal devices exhibit corrosion or oxidation, the product should be retired.

 

Pins and Springs:

If any metal parts or metal equipment show pin deformation, or other damage listed above, or if the springs do not work properly, the product should be retired.

 

Moving Parts:

If movement of any moving parts is limited, use the recommended lubricant. If the problem persists, the product needs to be retired from further use.
