ASTM F1592 is a Standard Test Method for Detention Hollow Metal Vision Systems (spy holes in prison doors).
This standard was created by the American Society for Testing and Materials, ASTM International, which was founded in 1898 as an international standard developing organization that publishes standards for a wide range of materials, products, systems, and services.
This standard was published by ASTM F33, which is a committee that specializes in developing standards for detention and correctional facilities. F33 has published 14 standards in this area.
ASTM F1592 deals with fixed detention hollow metal vision systems of various materials and types of construction. The detention hollow metal vision systems are used by several organizations.
Hollow metal vision systems are used in wall openings, such as hollow metal doors of the type commonly used in correctional and detention facilities. These vision systems allow the doors to function effectively as barriers while enabling correctional officers, etc. to observe activity on the other side of the door. Vision systems in hollow metal doors can be permanently sealed with security glass, or can be designed to allow limited passing of items through the door (such as meal trays, reading materials, etc.).
ASTM F1592 was developed to provide for standardized determination of a vision system's ability to withstand an inmate's attempt to remove, disable, or vandalize the system, and to prevent escape, passage of contraband, or unauthorized access to secure spaces. The standard can be used to evaluate vision system's in other than hollow metal as long as procedures are adhered to.
