ISO 8102-2:2021

Overview

ISO 8102-2:2021 specifies electromagnetic compatibility (EMC) immunity requirements for apparatus used in lifts, escalators and moving walks that are permanently installed in buildings. It defines immunity performance criteria and test levels intended to protect basic safety functions in the electromagnetic environments typical of residential, office and light‑industrial buildings. ISO 8102-2:2021 replaces ISO 22200:2009 and is a type‑C standard aligned with ISO/IEC directives.

Keywords: ISO 8102-2, electromagnetic compatibility, EMC immunity, lifts escalators moving walks, safety circuit immunity

Key topics and technical requirements

• Scope and exclusions: Applies to apparatus and assemblies integrated into lift/escalator/moving‑walk systems; excludes environments such as radio transmitter stations, railways/metros, heavy industrial plants and power stations, and equipment manufactured before publication.
• Immunity performance criteria: Two immunity levels are defined - higher levels for safety circuits and lower levels for general function circuits. A new performance criterion C is included for voltage dips and interruptions.
• Test types and references: Tests are specified by reference to IEC/EN EMC test standards, including:
  • IEC 61000‑4‑2 (ESD),
  • IEC 61000‑4‑3 (radiated RF fields),
  • IEC 61000‑4‑4 (electrical fast transient/burst),
  • IEC 61000‑4‑5 (surge),
  • IEC 61000‑4‑6 (conducted RF),
  • IEC 61000‑4‑11 (voltage dips/interruptions).
• Practical test guidance: Assemblies may be tested together, but where safety circuits are present the immunity of those circuits must meet the safety circuit requirements. Travelling cables likely >5 m must be represented by a sample of at least 5 m in tests. It is assumed mobile phones/radios are not placed within 200 mm of safety circuits and that safety‑only ports are ≤100 A unless otherwise stated.
• Ports and measurement: Tests target enclosure ports, signal/control ports, monitoring/remote‑alarm ports, and AC/DC power ports with different criteria based on current rating.

Applications and users

ISO 8102-2 is intended for:

• Lift, escalator and moving‑walk manufacturers (design and compliance),
• System integrators and installers (installation and EMC environment assessment),
• EMC testing laboratories (type and assembly testing),
• Safety engineers and regulators (certification, conformity assessment),
• Maintenance/service providers and building owners concerned with operational safety under electromagnetic disturbance.

Practical benefits include reduced risk of unintended behavior caused by ESD, radiated RF, power disturbances and conducted interference, and clear guidance for specifying and testing safety‑critical equipment.

Related standards

• ISO 12100 (type‑C standard context)
• IEC 61000 series and CISPR 32/35 (referenced test methods and product immunity/emission guidance)

For compliance planning, pair ISO 8102‑2 immunity requirements with ISO 8102‑1 emissions guidance and the referenced IEC/CISPR test standards.
