This standard specifies the requirements for materials, components, dimensions, and performance for prefabricated modular steel scaffolds. It covers standards (verticals), ledgers (horizontals), transoms, and accessories to ensure their strength, stability, and interchangeability for use in construction and maintenance.
Specifies requirements for prefabricated steel modular scaffolds, their components, and assemblies.

Minimum slip load for a right-angle coupler6.0 kN
Practical Notes
Ensure all components are from the same manufacturer or system to guarantee compatibility and load-carrying capacity as per testing.
Visually inspect all components for damage, corrosion, or distortion before erection, as this code's specifications apply only to components in good condition.
Verify the manufacturer's mark and the third-party inspection mark on components as specified in Clause 9 to ensure compliance.
