Elevator inspection certificate and Escalator inspection certificate, also known as an Elevator permit and Escalator permit is a certificate/permit that show whether the elevator[1] (or escalator) has passed an periodic examination or not. they usually in a form of regular A4-size paper, card or a sticker. For elevators, they are normally displayed inside the elevator car[2][3][4][5][6], either displayed on the elevator wall or hidden behind a cabinet. For escalators, they are normally displayed near the escalators entrances.

Some countries like the United Kingdom may don't need to present the inspection certificate but they also need to pass the periodic examination before they can operate to every users.[3]

Introduction

For the legal responsibility, every elevators (or escalators) must be inspected for every half of the year to two years (called periodic examination[7]). The inspection procedure mainly consists of inspection of either all the safety devices (like overspeed brakes and governor, braking system for traction elevators, pipe-broke stop value for hydraulic elevators, alarm, intercom, door interlocks, etc.) installed in the elevators or all the safety devices (like limit switches and emergency stop buttons) installed in the escalators (These include new installations). Sometimes, re-inspection will applied for major alterations (including modernization)[8].

Additionally, if the elevators (or escalators) fail the periodic examination (or not inspected after the specifc period), the "Order Prohibition" or similar sheet will be post on the elevators (or escalators) to notify that can't be operated.
