Cut-Resistant Hand Protection

A company has to safeguard it's employees and Protect them from on-the-job injuries. This Is a difficult task for the safety officers especially with all the sources of false information, myths and misnomers surrounding personal protective equipment (PPE). As you get more into detailed study of a particular PPE in our case cut-resistant gloves the information could certainly exacerbate the issue.

A study of industrial Workplace injuries reveals that arm, Hand and finger injury Statistics are higher than other body parts. 

The first chart illustrates, in percentage ters the incidence of injury that occurs to hands and fingers in the workplace- relative to other body parts. The second chart illustrates in percentage terms, the incidence of cut injury to workers in the US for year 2006. It has been noticed hat percentage of cut injuries are more 12.4% out of which 23.2% are hand / wrists area.

Cut resistant Test Methods

“The two globally acceptable  performance standards for cut resistance: the European standard EN388, used in Europe, APAC, South America, Mexico and parts of Canada and the US; and the ANSI/ISEA 105 standard, mainly used in North America,”  “These different standards are non identical and do not correlate, with a possibility to  confuse the implementation of the correctly specified PPE  for the job.”

We need to study  the differences between these standards, as well as the test methods specified in these standards, in order to comprehend the capabilities and the performance of a  ppe against per the specification label.

Both the ASTM F1790’05 and ISO 13997 standard explain the methods for testing the cut resistance; the TDM and the updated CPP test, while the ASTM F1790’97 only describes the old CPP test for measuring cut performance. From a principle point of view,  the functionality of both the CPP and TDM method similar. They measure the pressure one can apply to a razor blade, while moving the blade over the fabric without cutting through the fabric at least 0.8 inch (20mm). CPP/TDM indicates how much force load is needed to slash / cut through a fabric

EN388 standard describes the coup test method for cut resistance, which is that, a circular blade is moving back and forth across the sample under a fixed load of 5N/500 gr, while rotating in the opposite direction of the linear movement.

Coup test indicates how much repetitive cuts on the same positions are needed to cut through.
