• Testing can be done using a 21G, 25G or 28G needle<br />
• The tests below used a 25G needle<br />
• Puncture probe (25G needle) travels at a 90˚ angle into a<br />
specimen at a velocity of 500mm/min<br />
• Amount of force necessary to puncture through the material/<br />
specimen is recorded in Newtons* to the nearest .01 N<br />
• This test is done 12 times for every material/specimen<br />
• The average of the 12 results is reported<br />
*The Newton is the Standard International unit of force. One Newton is the force<br />
required to cause a mass of one kilogram to accelerate at a rate of one meter<br />
per second squared in the absence of other force-producing effects. We have<br />
converted Newton’s to grams.<br />
