This report establishes performance requirements for sliding glass units to be used in residences as well as methods of test for these doors' resistance to force entry by unskilled and semiskilled burglars.
Abstract
This standard covers class 1 units, designed to prevent entry by most unskilled burglars, and class 2 units, designed to prevent entry by most semiskilled burglars. Class 1 units provide a minimum level of physical security, while class 2 units provide a moderate level of physical security. The report includes definitions for glazing, keeper, latch, latch operator, locking device, loiding (a method of manipulating a locking device from the outside), sliding glass door frame, sliding glass door unit, stile, and strike. There are requirements listed for classification, failure criteria, resistance to disassembly, and resistance to loiding. Locking device stability, door panel removal resistance, locking device strength, and fixed-panel fastening strength are further specifications, as are meeting stile fastening strength, and glazing impact strength. Test methods include standards for sample and sample preparation, test sequence, disassembly test, loiding test, latch operator loiding force test, and latch loiding force test. locking device stability tests, door panel removal tests, locking device strength tests, fixed-panel fastening strength tests, and stile fastening and glazing impact strength tests are additional methods covered. Test equipment includes low-range tensile loading device, medium-range tensile loading device, high-range tensile loading device, loiding tools, and impactor. Diagrams, a picture, and a table are included.
