New technologies and standards based on performance

What will the authorities AHJ inspectors?

Flowchart: Introduction

Explanatory block diagram is shown in an annex to the standard ASME A17.7-2007 / CSA B44.7-07 and shows the role of, the jurisdiction of which is the question (AHJ) in the process of adopting a new technology. Location and size of the function block body in the AHJ this scheme does not give an idea of ​​the importance of his role. The ancients said: «All roads lead to Rome.» So here: all the processes go through a body AHJ. Let’s first look at the process.

The new technology of the first type

There are three options for compliance with PBC. The first one refers to the equipment or systems conforming to standards

ASME A17.1 / CSA B44 («safety standard elevators and escalators»). Compliance is usually very clear, and this option is to establish a correspondence between the standards A17.7 / V44.7 and A17.1 / B44. AHJ Authority or administrative body usually give permission to install or request to make changes, depending on the situation. The block diagram can be seen a straight path from the design of a new product to the AHJ authority and, eventually, to the installation of the equipment.

The new technology of the second type

The second option provided for a standard RVS — this is a case where some parts of the system to meet the standard A17.1 / B44, while others do not, or are not described in this standard. In this case, the manufacturer will identify those parts which correspond to the standard. Parts that do not meet the standard or not specified in it, pass the evaluation process, which begins with the identification of significant global security requirements (GESR). Then, the risk assessment (RA) with the identification, where applicable, the security settings (SP), risk reduction and documenting compliance with a standard (CCD). CCD document is then sent to the authorized organization on certification of elevators / escalators (AESO). The organization estimates AESO CCD document in terms of the correctness of procedures performed, and accuracy of the technical content of the document and the security structure. If AESO accepts the document CCD, it gives the manufacturer a certificate of conformity (COC). If the CCD is not taken AESO organization, it is returned to the manufacturer to fix bugs or deficiencies of information needed AESO organization. The procedure is repeated for as long as AESO not approve the document of CCD and will not issue a certificate COC. Then, the manufacturer brings COC certificate in AHJ authority or regulatory body, which will review the documents and issue a permit.

The new technology of the third type

The third option involves the process of establishing compliance with the requirements of GESR, specified in the standard RVS. In this case, all components are described above evaluation process shown in the flowchart. This embodiment relates more to the components, and not to the whole elevator.

During the whole process is very important point to note: all pass through the body AHJ. According to the inscriptions on the block diagram, it is recognized that the body AHJ, based on their capabilities and resources in their jurisdiction may act as certification of the organization instead of AESO.

This process is provided for the standard RVS is an advantage for organ AHJ, which is no longer necessary to impose the previous version of section 1.2 of the standard A17.1 / B44, as allowed deviations and ensure the rights of providing equivalent safety systems using new technologies.

For the successful implementation of the entire process is essential:

1) adoption of the standard A17.7 / V44.7 in all jurisdictions;

2) the recognition of organizations AESO each jurisdiction;

3) adoption authority AHJ COC certificate issued by the organization AESO.


In one of the next issues of the journal «Elevator World» we elaborate on AESO organizations and their role in the evaluation of new technologies and the application of the standard RVS.
