| 1 | Applicable safety code | EN 81-20 and EN 81-50 are European standards covering safety rules for the construction and installation of lifts, including passenger and goods-passenger lifts. | The applicable standard and edition, conformity documents, and the exact lift model and configuration covered. | A standard’s applicability depends on the installation location and the lift design; a general brochure statement is not model-specific proof. |
| 2 | North American code pathway | ASME A17.1/CSA B44 is a safety code for elevators and related equipment in jurisdictions that adopt it. | Written confirmation of the locally adopted code and edition, plus required approvals or inspection records for the proposed installation. | Building and elevator requirements vary by jurisdiction, so the design must match local rules and authority requirements. |
| 3 | Energy-class method | ISO 25745-2 provides methods for calculating and classifying the energy performance of lifts. Its classification uses classes A to G. | An ISO 25745-2 energy calculation or classification report identifying the assessed model, assumptions, and operating conditions. | An A–G class is an energy-performance result, not a safety certification or a guarantee of a particular household bill. |
| 4 | Energy-class evidence | ISO 25745-2 classification depends on calculated energy performance under the method’s stated assumptions; actual use can differ with traffic and operating patterns. | The class and underlying calculation, including standby and operating-energy assumptions where applicable. | Comparisons are meaningful only when the models are assessed on a comparable basis. |
| 5 | Lift type and configuration | Residential lifts can differ in drive system, rated load, travel, speed, entrance arrangement, and intended building use. | A model-specific specification showing drive type, rated load, travel, speed, number of stops, and permitted installation conditions. | A specification suitable for one home or layout may not suit another; compare like-for-like configurations. |
| 6 | Emergency operation and rescue | Applicable lift safety rules and local requirements govern safety provisions; emergency arrangements depend on the lift design and installation. | The documented emergency communication, power-loss behavior, rescue procedure, and responsible service contact for the proposed system. | Residents and responders need clear instructions for a power failure or lift stoppage. |
| 7 | Door and access safety | Lift safety design includes requirements relevant to doors, access, and protection of passengers; exact provisions depend on the applicable code and lift type. | Technical details for landing and car doors, protective devices, clear opening, and any applicable access provisions. | Door operation and usable access affect both safe entry and everyday convenience. |
| 8 | Installation and site requirements | Lift installation requirements depend on the selected system, building conditions, and applicable regulations. | A site survey and written requirements for pit, overhead, shaft or enclosure, power supply, structural support, and building work. | Early confirmation can help avoid redesign, unexpected construction work, and installation delays. |
| 9 | Maintenance and service support | Maintenance needs and intervals are equipment- and jurisdiction-specific; the manufacturer’s instructions and local rules should be followed. | The maintenance schedule, service scope, response arrangements, spare-parts availability, and warranty terms. | Ongoing service affects reliability, safe operation, and the owner’s long-term costs. |
| 10 | Comparable final evaluation | Safety compliance, energy classification, suitability, and lifecycle service are separate evaluation factors and should not be treated as interchangeable. | A written quotation with model identification, code basis, energy evidence, installation scope, exclusions, warranty, and service costs. | A complete, model-specific proposal makes it easier to compare suppliers without relying on unsupported rankings or marketing claims. |
