IS 3564:1995 is the Indian Standard (BIS) for hydraulically regulated door closers -specification. This standard specifies the requirements for materials, dimensions, manufacture, performance, and testing of exposed type hydraulically regulated door closers used in buildings.

Door Controls - Closers
Covers performance, cycle life, materials, and grading for various types of door closers, but uses a different classification system.
Key Differences
≠IS 3564 classifies closers into four sizes based on door mass (20 kg to 80 kg), whereas EN 1154 uses seven 'power sizes' based on closing moment in Newton-metres (Nm), providing a more precise performance-based classification.
≠The minimum endurance testing requirement in IS 3564 is 100,000 cycles, which is significantly lower than the 500,000 cycles mandated by EN 1154 for all closers.
≠EN 1154 includes a mandatory digit in its classification code for suitability on fire/smoke doors, which requires separate testing to EN 1634-1. IS 3564 addresses suitability for fire doors but does not integrate a specific fire performance rating into its primary classification system.
≠The thermal stability test in IS 3564 is conducted over a range of 0°C to 45°C, while EN 1154 requires satisfactory operation over a much wider and more demanding range of -15°C to +40°C.
Key Similarities
≈All standards fundamentally cover the same product: hydraulically regulated door closing devices, and share the primary objective of ensuring a door closes in a controlled and reliable manner.
≈Both IS 3564 and its international counterparts require closers to have adjustable features, specifically for controlling the general closing speed and the final latching speed.
≈The standards employ similar core testing principles, including measurements for closing time, operational efficiency (ratio of closing force to opening force), and durability through cycle testing.
≈All standards include requirements for material specifications and mandate corrosion resistance testing, typically a neutral salt spray test, to ensure product longevity.
