1 In accordance with the method given in GB/T 20900-2007, this document carries out risk assessment on the elevator equipment body and construction-related items in use: Based on this, the safety evaluation method and procedure of the elevator in use are given: 0:

2 When evaluating the risk level of the in-use elevator equipment body and building-related items, the evaluation content and requirements shall be based on the latest current technology: Technical standards and engineering experience, with a view to meeting the basic safety requirements of the elevators in use, through gradual updates, renovations, repairs, as soon as possible Possibly up to the latest level of safety technology: 0:

3 Users can refer to GB/T 24804 to take protective measures to eliminate the Prioritize and reduce risk items, and gradually eliminate or reduce related risks in order of priority: 0:

4 In order to make the risk assessment results of different assessment agencies and assessors on specific risk scenarios as consistent as possible, the appended Appendix A and Appendix B give the risk assessment reference values of the equipment body and building-related evaluation items respectively: Safety assessors are on site to confirm When determining the risk level and risk category of specific evaluation items, you can also refer to the method given in 4:5 of GB/T 20900-2007, and comprehensively consider Factors such as the technical standards adopted in the manufacture and installation of the equipment, the actual safety conditions, and the operating environment shall be considered: Specifications for safety assessment of elevators in use

1 Scope

GB/T 42615-2023 addresses a problem that grows with every year of a building's life: a lift installed to the code of its day, maintained ever since, and now decades old. It still passes its periodic inspection, because inspection asks whether the lift conforms to what it was built to. It does not ask whether the machine as it now stands presents an acceptable level of risk. This document sets out how to answer that second question. It specifies the requirements a safety assessment body must satisfy - its basic standing, its personnel, its instruments and equipment, and its quality assurance system - and then the assessment procedure itself: the preparatory work and the determination of scope, the risk analysis and risk evaluation with the evaluation items and their requirements, the determination of an overall safety condition grade, and the risk reduction measures that follow from it, ending with the requirements for the assessment report. It applies to traction drive lifts with a rated speed up to 6.0 m/s and hydraulic drive lifts up to 1.0 m/s. Under ICS 91.140.90 and CCS Q78, it is the working document for lift inspection bodies, maintenance companies and the building owners who must decide between modernising a lift and replacing it.

This document specifies the requirements of safety assessment agencies and safety assessment procedures for elevators in use (including preliminary preparations, risk assessments, and comprehensive safety conditions): Level determination, risk reduction measures), basic requirements for assessment reports, etc: This document applies to traction drive elevators with a rated speed not greater than 6:0m/s, and hydraulic drive elevators with a rated speed not greater than 1:0m/s Move the elevator: For traction drive elevators whose rated speed is greater than 6:0m/s, this document can be referred to:

Note: In special cases (such as: disabled persons using elevators, fire situations, potentially explosive atmospheres, extreme weather conditions, earthquake situations or the transportation of dangerous goods In addition to the requirements of this document, relevant additional requirements may need to be considered: This document does not apply to utility lifts and home lifts:
