Puncture Resistant Standard
Puncture Resistance – The purpose is to test shoe's capability in the function of Penetrate Resistant. Result shows the resistance ability which sharp objects such as nails, glass or metal penetrating through the outsole. Protection is provided by a steel pad or puncture resistant material imbedded in the insole of the safety shoes. The steel resistant pad are tested using a sharp steel pin forced into the pad at a determine speed. The force required to puncture the device is measured. The protection pad is also tested for flexibility and oxidation (rust) resistance.
ASTM
Puncture Resistant (PR) footwear must also meet the Class 75 requirements for impact and compression resistant footwear.
The puncture resistant insole must withstand a puncture force of 270 lbs., will not crack after 1.5 million flexes and show no signs of corrosion when exposed to a 5% salt solution for 24 hours.
CSA
Footwear with protective sole inserts must also meet the Grade 1 requirement for impact resistant footwear. The protective insert shall cover the sole including the heel area.
The puncture resistant insole must withstand a puncture force of 1200 newtons, will not crack after 1.5 million flexes and show no signs of corrosion when exposed to a 5% salt solution for 24 hours.
Footwear is labeled with a green triangle.
EN
Penetration Resistant Footwear must be tested in accordance with EN ISO 20344:2004. The force required to penetrate the sole unit shall not be less than 1,100 newtons. The metal insole must not crack after 1 million flexes and show no more than 5 areas of corrosion smaller then 2.5 mm2 when exposed to a 1% salt solution for 7 days. Non-metallic penetration resistant insoles will be tested according to EN 12568:1998.
SINGAPORE
Tested in accordance with SS 513 : Part 2 : 2005
