Specifies requirements for hasps and staples for doors and windows.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Product Classification | By nominal length (e.g., 75, 90, 115, 150 mm) and type. | By performance grade (Grade 1, 2, 3) based on strength, cycle, and finish tests. | ANSI/BHMA A156.16-2018 |
| Strength Test (Tensile Load for ~115mm size) | 1500 N (153 kgf) for 1 minute without failure. | 1780 N (400 lbf) for Grade 3; 4450 N (1000 lbf) for Grade 1. | ANSI/BHMA A156.16-2018 |
| Corrosion Resistance Test (Typical) | Prescribes coating thickness (e.g., Zinc plating min 5 microns per IS 1573 SC2) without mandatory hours test. | Performance-based: must pass a salt spray test (e.g., 96 hours for Grade 1) per ASTM B117. | ANSI/BHMA A156.16-2018 |
| Hinge Pin Diameter (for 115mm safety hasp) | Prescribed as 4.50 mm (nominal). | Not specified; determined by manufacturer to meet performance grade. | ANSI/BHMA A156.16-2018 |
| Hasp Plate Material | Mild steel sheet conforming to IS 1079 or cold-rolled mild steel strip conforming to IS 513. | Not prescriptively specified; any material (typically carbon steel) that meets performance requirements is acceptable. | ANSI/BHMA A156.16-2018 |
| Hasp Plate Thickness (for 115mm safety hasp) | Prescribed as 2.00 mm (nominal). | Not specified; determined by manufacturer to meet performance grade. | ANSI/BHMA A156.16-2018 |
