Arc Rating: A value of the energy necessary to pass through any given fabric to cause with 50% probability a second or third degree burn. This value is measured in calories/cmÂ². The necessary Arc Rating for an article of clothing is determined by a Hazard/Risk Assessment and the resulting HRC. Usually measured in terms of ATPV or EBT. Simple put the ARC rating determines the protective characteristics of the fabric. The higher the ARC rating value the greater the protection.
Arc Length. Definition: The distance along the curved line making up the arc. (See also Angle measure of an arc .). Try this Drag one of the orange dots that define the endpoints of the blue arc. The arc length will be continuously calculated. The arc length is the measure of the distance along the curved line making up the arc. It is longer than the straight line distance between its endpoints (which would be a chord). There is a shorthand way of writing the length of an arc: This is read as The length of the arc AB is 10.
