Comprehensive Guide to Door Handles Specifications and Manufacturing

Foreword

The Indian Standard for door handles, now in its fifth revision, has been adopted by the Bureau of Indian Standards. Previous revisions were made in 1965, 1972, 1979, and 1987. This latest revision reflects practical experience, updates to referenced standards, and changes in dimensions and sampling clauses.

The technical committee responsible for this standard is listed in Annex C. Compliance is assessed by rounding off the final values according to IS 2: 1960.

Door Handles - Specification

1. Scope

This standard defines the requirements for the materials, manufacture, dimensions, and finish of door handles. It applies to handles commonly fixed to doors.

2. References

Essential Indian Standards are listed in Annex A and are integral to this standard.

Door handles are categorized by material:

• Type 1: Cast iron, malleable cast iron, cast brass, cast aluminium, or zinc alloy die-casting.
• Type 2: Mild steel.

• Type 4: Cast brass, aluminium alloy pressure die casting, and extruded aluminium alloy.

4. Materials

Materials must conform to the standards outlined in Table 1:

• Mild Steel: Grade 0 of IS 1079: 1994.
• Cast Brass: LCB 2 of IS 292: 1983.
