IS 14665:1999 Part 1 is the Indian Standard (BIS) for installation, operation and maintenance of electric passenger and goods lifts — part 1: passenger and goods lifts. This code of practice specifies the requirements for the installation, operation, testing, and maintenance of electric traction passenger and goods lifts. It ensures safety and reliability by detailing procedures for pre-installation checks, on-site work, final inspection, handover, and periodic maintenance schedules. It is a fundamental document for lift installers, inspectors, and building maintenance personnel in India.
Provides general requirements for the installation, operation and maintenance of electric passenger and goods lifts (commonly referenced for installations from its period).
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
