This is a test of a shoe's capacity to protect the toe area of the foot against falling objects. For Impact testing, a weight is dropped onto the protective toe cap area of the footwear. Each standard identifies the atmospheric conditions of the test, the shape of the striker, the amount of weight and distance from which the weight must be dropped, the velocity of the drop and the impact energy delivered. The clearance remaining inside the cap after impact is then determined.
This is a test of a shoe's capacity to protect the toe area of the foot against heavy rolling objects. For Compression testing, the toe cap area of the footwear is compressed between parallel platens at a given rate of speed until the required compressive force is reached. The clearance remaining inside the cap after the compression is then determined.
This test measures the level of protection provided to the upper foot (metatarsal bones) and toe areas. Footwear offering metatarsal protection is designed to prevent or reduce injuries when the toe and metatarsal areas of the foot are exposed to "drop" hazards. Metatarsal protection safety shoes may be constructed with either internal or external metatarsal guards. For testing, a wax form is fit into the footwear and a weight is dropped onto the protected metatarsal area of the footwear, similar to the impact test. The height of the wax form after impact is then determined.
Our footwear reduces the possibility of sharp objects (nails, glass or metal) penetrating through the outsole causing injury to the foot. Protection is provided by a steel or puncture resistant material imbedded in the insole of the footwear. Puncture resistant devices are tested using a sharp steel pin forced into the device at a given speed. The force required to puncture the device is measured. The devices are also tested for flexibility and corrosion resistance.
This type of footwear is designed to provide a secondary source of protection against accidental contact with live electrical circuits, electrically energized conductors, parts or apparatus under dry conditions, reducing the potential of electric shock. Protection is severely deteriorated in wet environments. To test electric shock resistant properties, the footwear is placed on a metal mesh platform acting as a large electrode. The footwear is filled with small metal spheres and a second electrode is placed within the spheres. A specified high voltage is applied to the footwear through the metal platform for a given length of time. Resistance is determined by the current flow (or leakage) through the footwear.
This footwear is constructed to reduce excess static electricity by conducting the charge from the body to the ground. The footwear allows for limited protection against incidental contact with live electrical circuits and should not to be worn around highly charged electrical equipment. It is recommended that static dissipative footwear be worn only in clean environments and worn in conjunction with static dissipative flooring. Test methods for Static Dissipation vary by standard, using either human subjects or metal spheres inside footwear that are placed on either a wet or dry base electrode plate. A specified voltage is applied for a prescribed time and the electrical resistance is measured. Test conditions also vary in specified atmospheric conditions.
Conductive footwear is designed to facilitate/ discharge static electricity from your body through your shoes into grounded floors. The floors must be grounded so that a charge can be dissipated properly, minimize static electricity and reduce the possibility of ignition of volatile chemicals or explosives. To test for conductivity, the footwear is placed on a base electrode plate. Depending on the standard, it is tested dry or in water. The footwear is filled with small metal spheres and a second electrode is embedded in the spheres. A specified voltage is applied for a prescribed time and the electrical resistance is measured
