ISO 8100-2:2026

Overview

ISO 8100-2:2026 is an international standard developed by the International Organization for Standardization (ISO), offering comprehensive requirements for the design, calculation, verification, and testing of essential lift components. It specifically applies to passenger lifts and goods passenger lifts, ensuring reliable transport of persons and goods. The standard covers critical aspects such as door locking devices, safety gears, overspeed governors, buffers, safety-related circuits, and mechanisms to prevent unintended movement or overspeed of lift cars.

This standard is part of the ISO 8100 series and complements safety rules outlined in ISO 8100-1. It is targeted at manufacturers, safety inspectors, and stakeholders involved in the design, installation, and maintenance of lifts, supporting safer and more efficient lift systems worldwide.

Key Topics

ISO 8100-2:2026 addresses the following major areas relevant to lift design and component verification:

• Verification of Door Locking Devices: Ensures door interlocks operate dependably under mechanical and electrical stress.
• Safety Gears Validation: Defines procedures to verify both instantaneous and progressive safety gears used to stop lift cars in emergencies.
• Overspeed Governor Testing: Specifies checks and tests to verify governor performance for overspeed protection.
• Buffer and Shock Absorption Tests: Details requirements for testing buffers that cushion lift movement extremes.
• Verification of Safety Circuits and SIL-Rated Circuits: Outlines how to validate circuits’ safety integrity levels (SIL) and protective functions.
• Ascending Car Overspeed and Unintended Movement Protection: Describes verification of protections against overspeed and unintended movement of the lift car.
• Suspension Means and Discard Criteria: Defines checks for ropes and compensation means, including criteria for discarding worn or damaged components.
• Calculation of Structural Components: Provides rules for calculating the strength and reliability of guide rails, rams, cylinders, rigid pipes, and fittings.
• Traction Calculation and Safety Factor Assessment: Covers how to evaluate traction drive systems and calculate safety factors for suspension means.
• Pendulum Shock Tests: Includes test requirements for assessing resilience of lift components to shock loads.
• Fault Exclusion for Electrical/Electronic Components: Details fault exclusion measures for safety-critical circuits and components.
• Design Rules for SIL-Rated Circuits: Ensures adherence to best practices in designing safety integrity level-rated circuits.

Applications

ISO 8100-2:2026 is vital for a range of practical applications in lift manufacturing, installation, and maintenance, including:

• Lift and Elevator Manufacturing: Ensures new lift systems comply with international safety and reliability benchmarks during design and production.
• Component Testing and Certification: Provides a basis for validating key components like doors, gears, and safety circuits before market release or installation.
• Regulatory Compliance and Safety Audits: Supplies authorities and safety inspectors with standardized criteria for auditing lifts.
• Maintenance and Modernization: Guides service providers in inspecting and maintaining critical lift elements, replacing or discarding components that fail to meet standards.
• Global Trade and Market Access: Facilitates access to international markets by harmonizing component requirements and testing protocols across regions.
