IS 9106:1979 is the Indian Standard (BIS) for rising butt hinges. This standard specifies the requirements for materials, dimensions, manufacture, finish, and marking for rising butt hinges. It covers hinges made of mild steel, brass, and aluminium in standard sizes of 75, 100, and 125 mm, intended for general building purposes.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Durability Test | 200,000 cycles under test conditions. | Graded system; e.g., Grade 7 is 200,000 cycles for heavy/severe duty. | BS EN 1935:2002 |
| Load Capacity Specification | Implied by hinge size for standard door types. | Explicitly tested and graded by door mass (e.g., Grade 11 = 80 kg door). | BS EN 1935:2002 |
| Hinge Rise | 10 mm min. rise for 100 mm hinge over 180°. | Not specified; it is a design feature of a specific product type, not a universal performance parameter. | BS EN 1935:2002 |
| Flap Thickness (100 mm Hinge) | 3.15 mm (for mild steel). | Not specified; thickness is a result of design choices made to meet performance grades. | BS EN 1935:2002 |
| Fire Door Suitability | Not specified. | Grade 1: Suitable for fire/smoke door use (requires specific testing). | BS EN 1935:2002 |
| Corrosion Resistance Test | Not specified; relies on finish adherence. | Required; e.g., Grade 3 = 96 hours in Neutral Salt Spray test (EN 1670). | BS EN 1935:2002 |
| Pin Material | Steel (for steel hinge) as per IS 1079. | Not specified, but material must allow hinge to pass all performance tests. | ANSI/BHMA A156.1-2016 |
