Needle Sharpness & Puncture Resistance Testing

Mecmesin - Webinar event
Moses Da Rocha
Kathryn Hawkes

Hypodermic needles are tested to determine how their design influences the ease of insertion into the skin, patient pain and skin trauma. They are also tested to determine their efficacy in piercing elastomer closures on vials. Sharpness is determined by measuring the penetration force of a needle into a known medium which closely replicates skin as well as actual elastomer caps.

The ‘hardness’ of elastomers is also measured to ensure smooth needle penetration without ‘blunting’ the needle.

What You’ll Learn in the Webinar and Live Demonstration:

  • Overview of Puncture and Penetration Force Testing
  • The importance of Needle Sharpness / puncture testing
  • Industries that Use Puncture Testing
  • Selecting the Ideal Testing Equipment
  • Selecting the Ideal Test Fixtures
  • Measuring Puncture (Peak) and Penetration (Average) Forces
  • Measuring Removal Force
  • Establishing Pass/Fail Criteria
  • Troubleshooting Inconsistent test results or non-repeatable tests
