IS 12817:1997 is the Indian Standard (BIS) for stainless steel butt hinges - specification. This standard specifies the requirements for materials, dimensions, manufacture, performance, and testing of stainless steel butt hinges. It covers various sizes of hinges used for doors, windows, and cabinets, ensuring quality through specifications on material grade (SS-304), dimensional accuracy, and durability via endurance and corrosion resistance tests.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Stainless Steel Material Grade | Grade 04Cr17Ni7 (similar to SS 304) or 02Cr17Ni12Mo2 (SS 316) per IS 6911 | Typically Austenitic Stainless Steel (e.g., Type 304, 316) to meet performance requirements | ANSI/BHMA A156.1-2022 |
| Endurance Test Cycles | 200,000 cycles for all hinges under the standard | Grade 7: 200,000 cycles (one of several durability grades available) | BS EN 1935:2002 |
| Endurance Test Cycles (Heavy Duty) | 200,000 cycles (no higher grade defined) | Grade 1: 2,500,000 cycles | ANSI/BHMA A156.1-2022 |
| Corrosion Resistance (Salt Spray) | 96 hours test pass required | Grade 4: 240 hours; Grade 5: 480 hours | BS EN 1935:2002 |
| Fire Resistance Rating | Not covered within this standard | Digit 4, Grade 1: Suitable for use on fire/smoke door assemblies | BS EN 1935:2002 |
| Hinge Flap Thickness (100 mm Hinge) | 2.5 mm (prescribed) | Not specified; hinge must pass performance tests for its designated grade and door mass | BS EN 1935:2002 |
| Static Load Test (Test 1 - Wear) | Vertical and lateral load applied to measure sag | Overload test: A hinge must support a door 75% heavier than its test mass rating without failure. | BS EN 1935:2002 |
