introduction
0.1 GB/T 24803 “Safety Requirements for Elevators” is intended to consist of the following four parts.
--- Part 1.Basic safety requirements for elevators. The purpose is to specify basic safety requirements by analyzing the dangers and risks encountered on elevators.
However, the basic safety requirements only specify the safety objectives of elevators.
--- Part 2.Safety parameters that meet the basic safety requirements for elevators. The purpose is to specify the safety parameters that are applied and implemented on elevators.
Parameters provide guidance and criteria for compliance with basic safety requirements in order to eliminate the hazards described in the basic safety requirements or reduce
The risks described in the basic safety requirements. However, safety parameters are not mandatory.
--- Part 3.Preconditions for conformity evaluation of elevators, elevator components and elevator functions.
Sufficient prerequisites.
--- Part 4.Evaluation requirements. Specifies the procedures for conformity evaluation of elevators, elevator components and elevator functions, as well as the conformity evaluation
Institutional conditions.
0.2 The purpose of GB/T 24803 (all parts) is as follows.
a) To establish a common level of safety for all persons using or associated with elevators.
b) To promote innovation in elevator technology that is not covered by current national safety standards while ensuring that the same level of safety is maintained.
As these innovations become applied technologies, they may later be included in descriptive safety standards.
c) help remove trade barriers.
0.3 This document has been developed in response to the need for elevator safety parameters.
0.4 Chapter 4 of this document describes the approach and methods used to develop this document; Chapter 5 provides guidance on the application and implementation of security parameters.
