IS 17464:2020 Part 2 is the Indian Standard (BIS) for safety rules for the construction and installation of lifts — lifts for the transport of persons and goods — examination and tests — part 2: periodic examinations and tests. This standard specifies the rules for periodic examinations and tests of existing passenger and goods lifts after they are put into service. It defines the schedule and procedures for checking safety devices and key components to ensure the lift remains safe for use throughout its operational life.
Specifies procedures for periodic examinations and tests of lifts to ensure continued safe operation.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! This standard is harmonized with the European standard EN 81-80, focusing on improving the safety of existing lifts.
! Maintaining a detailed logbook for the lift is mandatory as per this standard and is the primary document reviewed during any inspection.
! The frequency of tests in Annex A (e.g., weekly, monthly, annual) is the minimum requirement; local statutory bodies (like the State Lift Inspectorate) may require more frequent or additional tests.

Key Differences
≠IS 17464 references Indian national standards for materials (e.g., IS codes for steel) and electrical components, whereas EN 81-50 refers to European Norms (EN) or ISO standards.
≠The administrative framework for type examination in India involves the Bureau of Indian Standards (BIS) and its accredited laboratories, differing from the European system of Notified Bodies operating under the EU Lifts Directive.
≠While harmonized, IS 17464 includes national annexes and considerations for Indian environmental conditions (e.g., higher ambient temperature and humidity ranges) which may affect component testing protocols.
≠For fire resistance testing of landing doors, IS 17464 references IS 3614 (Part 2), while the EN framework specifies its own dedicated standard, EN 81-58.
Key Similarities
≈The methodology for testing safety gears (both instantaneous and progressive types), including the required deceleration range (0.2 gₙ to 1.0 gₙ), is identical.
≈Both standards specify the same pendulum shock test procedures (for both soft and hard body impacts) for verifying the mechanical strength of car and landing door panels and glass walls.
≈The type examination procedures for overspeed governors, including verification of tripping speed ranges and the required tension force for engagement, are directly aligned.
≈Testing requirements for energy-dissipation type buffers (oil buffers) are consistent, specifying criteria for retardation, limits on peak deceleration, and post-test condition.
≈The test methods and performance criteria for Unintended Car Movement Protection (UCMP) devices are harmonized, ensuring a consistent level of safety against uncontrolled movement.

Table A.1 - Schedule of Periodic Examinations and Tests
The safety gear, overspeed governor, and buffers must be tested at least once a year (Annex A).
What load is used for the annual brake test?+
The braking system is tested with the car carrying 125% of its rated load (Clause 5.3.2).
Who is qualified to perform these periodic tests?+
The tests must be performed by a 'competent person' or an authorized body as recognized by the relevant statutory authority.
What does a routine monthly lift check involve?+
Monthly checks typically include testing of levelling accuracy, door operation, safety edges, light curtains, and the alarm/intercom system (Table A.1).
