Line 4 is only used when more than three sections of the ASTM standard apply. Conductive Cd footwear is intended to provide protection for the wearer against hazards that may result from static electricity buildup and to reduce the possibility of ignition of explosives or volatile chemicals. The footwear must facilitate electrical conductivity and the transfer of static electricity build up from the body to the ground.
The electrical resistance must range between zero and , ohms. Electrical shock resistant EH footwear is manufactured with non-conductive electrical shock resistant soles and heals. The outsole is intended to provide a secondary source of electric shock resistance protection to the wearer against the hazards from an incidental contact with live electrical circuits, electrically energized conductors, parts or apparatus. It must be capable of withstanding the application of 14, volts at 60 hertz for one minute with no current flow or leakage current in excess of 3.
Static dissipative SD footwear is designed to provide protection against hazards that may exist due to excessively low footwear resistance, as well as maintain a sufficiently high level of resistance to reduce the possibility of electric shock. The footwear must have a lower limit of electrical resistance of ohms and an upper limit of ohms. Puncture resistant PR footwear is designed so that a puncture resistant plate is positioned between the insole and outsole. It is an integral and permanent part of the footwear.
The device must show no sign of corrosion after being exposed to a five percent salt solution for hours. The puncture resistant footwear must show no signs of cracking after being subjected to 1. It is intended to protect the foot area between the toe and lower leg. Dielectric insulation DI footwear is designed to provide additional insulation if accidental contact is made with energized electrical conductors, apparatus or circuits.
Protective Footwear Standards (USA) – ASTM F2412 and ASTM F2413
This specification covers the minimum design, performance, testing, and classification requirements, and prescribes fit, function, and performance criteria for footwear designed to protect against a variety of workplace hazards. It is not the intention of this specification to serve as a detailed manufacturing or purchasing specification. Instead, this specification can be referenced in purchase contracts to ensure that minimum performance requirements are met. Footwear conforming to this specification must meet the performance requirements for the following: impact resistance for the toe area; compression resistance for the toe area; metatarsal protection that reduces the chance of injury to the metatarsal bones at the top of the foot; conductive properties that reduce hazards resulting from static electricity build-up and reduce the possibility of igniting explosives and volatile chemicals; electric shock resistance; static dissipative SD properties to reduce hazards caused by exceedingly low footwear resistance that may exist where SD footwear is required; puncture resistance of footwear bottoms; chainsaw cut resistance; and dielectric insulation. The purpose of this standard is to summarize the requirements for certifying protective footwear by independent, third party laboratories. Following these assessments, the requirements of additional sections—such as metatarsal protection, conductive protection, electric hazard resistance, static dissipative protection, and protection against punctures—can be met. All footwear manufactured to the ASTM specification must be marked with the specific portion of the standard with which it complies.

You must reduce risks by employing certain protocols to protect the stakeholders and any other individuals that are involved in the workplace. If hazards are present you must enforce engineering and governmental controls. Wearing the proper personal protective equipment PPE is essential in the workplace. A very important aspect of any PPE package is the protective footwear. The particular type and kind of this footwear are dependent on the hazards that are present in the workplace. And, it is mandated by law that employees in potentially hazardous conditions are to wear footwear that is designed to protect the foot. This is important especially in areas where the dangers of acquiring foot injuries are at hand, or likely to be present.
ASTM F2413-11 - Performance Requirements for Protective Footwear
Print this page November 13, ASTM F covers minimum requirements for the performance of footwear to provide protection against a variety of workplace hazards that can potentially result in injury. ASTM F covers minimum requirements for the design, performance, testing and classification of protective footwear. All footwear manufactured to the ASTM specification must be marked with the compliance to the specific portion of the standard. One shoe of each pair must be clearly and legibly marked stitched in, stamped on, pressure sensitive label, etc. The marking must be enclosed in a rectangular border and a four-line format is suggested.
