When variations in the evenness of the? When a stair-rail system is higher than 0. The vertical clearance between the handrails shall be at least 9 in. The members shall be arranged to discourage climbing. The top of the toe board shall not be less than mm 4 in. The hardware chosen for attaching handrails to balusters or walls shall be such that projecting lugs, devices, or other construction elements shall have no sharp edges or dangerous protrusions.
Wall handrails at stairs and ramps and other handrails that are not continuous shall be extended horizontally for a distance of at least mm 2 12 in. The handrail shall project no more than 89 mm 31? The vertical clearance in a recess shall be in accordance with the provision in 4.
The hardware chosen for attaching the transfer rails shall be such that projecting lugs, devices, or other construction elements shall not interrupt the continuous sliding of arm or hand or catch loose clothing. The transfer rails, including their fasteners, shall have no sharp edges or dangerous protrusions. The transfer rail top surface shall not be abrasive.
Design Considerations 6. Railing systems and rails are usually not provided at the landing side of loading docks and where the vertical distance between adjacent levels is 0. In different environments and for different applications, these building elements serve different purposes; therefore, the design and performance requirements vary.
Applicable building speci? Minimum Criteria for Static Loads and De? The horizontal and vertical loadings as well as the concentrated and uniformly distributed test loads shall not be applied concurrently. The exceptions to these test loads are indicated in 7. The test loads are applicable for railing systems with supports not more than 2. When subject to impact or panic loading, the designer shall evaluate the system for increased test-load requirements.
If an end post is not included in the rail system to be evaluated, the load shall be applied at the midspan of the rail system. Product Condition 8. Keywords 9.

Standard Specification for Permanent Metal Railing Systems and Rails for Buildings
Powered by mwForum 2. Not logged in American Welding Society Forum. By yojimbo Date Couldn't decide which formum was most approriate, hopefully this might get some traffic and answers. A google search has provided web pages offering to sell the relevent information, but I can likely locate them at the university engineering library. Is anyone familiar with these codes? I am trying to determine if they require the fabricator to provide engineering and or testing for the railings.
