IS 2502 vs BS 8666: Key Differences in Rebar Detailing Standards

When working on international rebar detailing projects, one of the first questions is: which standard applies? The two most common standards are IS 2502 (India) and BS 8666 (UK and Middle East).

IS 2502 ? Indian Standard

IS 2502 is the Code of Practice for Bending and Fixing of Bars for Concrete Reinforcement published by the Bureau of Indian Standards. It specifies bend radii, hook lengths, and lap lengths for Indian construction projects.

BS 8666 ? British Standard

BS 8666 is the British Standard for Scheduling, Dimensioning, Bending and Cutting of Steel Reinforcement for Concrete. It is widely used across the UK, UAE, Qatar, and other Gulf countries.

Key Differences

• Shape codes differ significantly between the two standards
• Bend radii vary based on bar diameter
• Hook and cog dimensions are specified differently
