SATRA, the research organisation, is helping to develop new European standards for stab-resistant body armor.

The company has made a new stab test rig that will measure the resistance of body armor.

"The wider implications for improved safety are clear," said SATRA's safety test expert David McKeown. "In addition to protecting police officers, this type of vest clothing is worn by nightclub staff and security guards as well as other workers who come into contact with the public such as hospital employees."

Several manufacturers have already submitted pre-production samples for test at SATRA's Safety Products Centre.
