ASTM F2957-13(2019)e1

Standard Specification for Ornamental Aluminum Fence Systems

ABSTRACT
This specification establishes the minimum requirements for architecturally coated, tubular picket, ornamental aluminum fence systems, namely, aluminum wrought iron fence, architectural metal fence, ornamental aluminum fence, ornamental fence, ornamental metal fence, picket fence, tubular picket fence, and vertical tube fence. The standard covers materials and their manufacture, structural testing, physical dimensions of the fence systems, workmanship, testing of surface finish, and certification.
SCOPE
1.1 This specification establishes the minimum requirements for architecturally coated, tubular picket, ornamental aluminum fence systems.  
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
