Description of New/Revised Technical Requirements
ClauseVerdictComment
--The revision below is to clarify that routine, periodic, and acceptance inspections and tests are required on existing equipment.

Additions to existing requirements are underlined below.
1.1InfoScope
1.1.3InfoApplication. This Standard applies to new installations only except Part 10, which applies to new and existing installations.
--The revisions below are to remove the allowance of the uppermost doors to be located up to 75 mm (3 in.) from the edge of the landing sill and duplicating the language for the location of the other doors thus requiring flush mounted doors at all landings. This will remove the hazard created by the ledge at the upper most floors, which may cause a wheelchair to overturn on its descent and prevent the potential for anyone from standing on the ledge.

Additions to existing requirements are underlined and deletions are shown lined out below.

--The revisions below are to add the requirement for collection of oil leakage to ropedhydraulic and chain-hydraulic lifts, as they are no less susceptible to packing gland leakage than direct plunger hydraulic lifts. Language consistent with A17.1 is added, requiring the collection container to be covered, to prevent contamination of the fluid so it may be reclaimed, and to prohibit the container from overflowing, which can lead to a hazardous condition in the area underneath the lift.
2.3.2 Hydraulic Driving Machines. Direct-plunger hydraulic driving machines, where used, shall conform to the requirements of para. 8.1, except para. 8.1.2.
Roped-hydraulic and chain-hydraulic machines shall also conform to the requirements of para. 8.1 except for paras. 8.1.1, 8.1.3, and 8.1.4.3, and 8.1.4.7.
8InfoDriving Means
8.1.4.7 Collection of Oil Leakage. Means shall be provided to collect for removal any oil leakage from the cylinder packing gland. The amount collected before removal shall not exceed 20 L (5 gal). The container shall be covered and shall not be permitted to overflow.
--Research data from the State University of New York – Buffalo IDeA Center and the UK indicate that a minimum rated load of 250 kg (550 lb) will accommodate an estimated 90th percentile of users of powered wheelchairs in the U.S. (see attached memos). The corresponding section regarding inclined platform lifts is also included, as the increase in minimum rated load is viewed as achievable for this equipment and installation settings. Increasing the minimum rated load will increase safety, in that the lifts will be able to handle typical current day users and mobility bases and reduce the chances of overloading. Additionally, increasing the minimum rated load to 250 kg will harmonize A18.1 with EN81-41 and EN81-40, respectively.

Additions to existing requirements are underlined and deletions are shown lined out below.

--The revisions below are to clarify that other types of standby power may be used on lifts, but if the standby power source is to be used in lieu of manual operation complying with 2.10.10, it must meet certain criteria. Reworded the criteria to equally weight building and battery power sources and insure both systems are capable of cycling the lift under full load for five cycles. Added a requirement for automatic transfer similar to the requirement in A17.1 and the IBC building code for elevators.

Additions to existing requirements are underlined and deletions are shown lined out below.

--Manual operation to move a lift to a terminal landing is typically a slow process performed with a manual hand crank. Requiring all lifts installed to 3.6.8.2 to be capable of being manually folded would reduce the obstruction in the circulation path in less time during an emergency situation. Clarification is added to indicate that the arms as well as the platform itself must be capable of being folded, and must remain in the folded position, in order to eliminate the obstruction in the circulation path. Added a new reference to Requirement 3.12, to be consistent with 2.10.10 by allowing standby power in lieu of manual operation and to clarify where to find the standby (emergency) power requirements.

Additions to existing requirements are underlined and deletions are shown lined out below.
3.6InfoPlatforms
3.6.8.2.5 Means shall be provided to manually fold the platform and passenger restraining arms. The platform and passenger restraining arms shall remain in the folded position after being manually folded.
3.10InfoOperating Devices and Control Equipment
3.10.10 Manual Operations. Means shall be provided to permit authorized personnel from a position outside the platform to raise or lower the platform manually along the path of travel, unless standby (emergency) power complying with Requirement 3.12 is provided. The means to raise or lower the platform shall be capable of moving the platform to a landing. For lifts installed in compliance with para. 3.6.8.2, means shall be provided to manually fold the platform unless the lift can be manually moved to a dedicated storage location that is provided at the upper or lower terminal landing away from the circulation path.
--Revised language reflects ASME’s recent decision to discontinue accreditation of certifying organizations and allows organizations to seek accreditation elsewhere while continuing certification of inspectors and inspection supervisors to the QEI-1 Standard.

Additions to existing requirements are underlined and deletions are shown lined out below.
10InfoRoutine, Periodic, and Acceptance Inspections and Tests
