IS 2681:1993 is the Indian Standard (BIS) for non-ferrous metal sliding door bolts (drops) with padlocks -specification. This standard specifies the requirements for materials, dimensions, manufacture, and finish of non-ferrous metal sliding door bolts (commonly known as aldrops) provided with padlock arrangements. It ensures the hardware is durable, correctly sized, and resistant to corrosion for use in building doors.

Practical Notes
! Ensure the correct finish (e.g., anodized for aluminum, polished for brass) is specified when ordering to prevent tarnishing.
! When installing, verify the alignment of the hasp and the staple to ensure the padlock can be inserted smoothly without applying force.

Key Differences
≠IS 2681 is a prescriptive standard, specifying exact materials (e.g., Grade CZ 108 brass) and dimensions. International standards like EN 12051 are performance-based, allowing any material or design that meets graded performance tests (e.g., for corrosion, durability).
≠EN 12051 uses a comprehensive 8-digit classification system to grade bolts on factors like category of use, durability, mass, fire resistance, corrosion resistance, and security. IS 2681 primarily classifies bolts by nominal length and type.
≠The provision for a padlock is a mandatory part of the scope for IS 2681, with specified hole diameters. In EN 12051 and ANSI/BHMA A156.16, this is an optional feature and not a basis for classification.
≠International standards mandate rigorous, quantified testing for durability (e.g., 10,000-25,000 cycles) and static load resistance (e.g., 1.5 kN force). IS 2681 focuses on dimensional accuracy and smooth manual operation without specifying cyclic endurance or load-bearing capacity tests.
Key Similarities
≈All standards cover the fundamental application of manually operated sliding bolts for securing doors.
≈All standards include requirements for the product's finish, stipulating that bolts must be free from sharp edges, burrs, and other manufacturing defects that could impede function or cause injury.
≈A core requirement across all standards is that the bolt must operate smoothly throughout its travel without requiring excessive force.
≈All standards require clear marking of the product, typically including the manufacturer's name or trademark, although the specifics of the marking differ.
