Overview
ISO/TS 8103-3:2024 - Escalators and moving walks - Part 3: Requirements from other standards (ASME A17.1/CSA B44 and Japanese codes) not included in ISO 8103-1 - is a Technical Specification that maps prescriptive requirements from ASME A17.1/CSA B44 and relevant Japanese codes to ISO 8103-1. It identifies section and requirement numbers in those external standards for items not covered in ISO 8103-1, and is intended to be used together with ISO 8103-1 to achieve equivalency where scopes overlap. The TS applies to new pallet- or belt-type escalators and moving walks and addresses significant hazards, foreseeable misuse, and related safety requirements.
Key topics and technical requirements
This document does not reproduce the full technical text from ASME or Japanese codes but references the specific clauses that users must consult. Major technical topics highlighted include:
- Structural design and component calculation - mapping of ISO clauses to ASME/JIS requirements for frames, steps, pallets and belts.
- Step, pallet and belt guidance and clearances - requirements for guidance, retention, and inter‑part clearances.
- Braking and drive systems - operational and auxiliary brake requirements, brake load determination and stopping distances; notes on allowable braking types (electro‑mechanical vs. electrical/permanent magnet as per referenced codes).
- Speed limits and protection - speed requirements for escalators and moving walks (ASME references define different speed definitions; escalator maximum often cited as 0.5 m/s in ASME guidance).
- Inspection covers, access and floor openings - locking, weight requirements and protection of floor openings in accordance with building codes.
- Ventilation apertures and balustrade dimensions - prevention of contact with moving parts, anti‑climb measures and dimensional constraints.
- Dynamic testing and fatigue evaluation - reference to ASME/JIS test procedures for step/pallet durability and crack evaluation.
Practical applications and users
This Technical Specification is practical for:
- Manufacturers and designers who need to design escalators and moving walks that comply with both ISO and region‑specific prescriptive codes.
- Safety engineers and risk assessors implementing hazard mitigation aligned with multiple jurisdictions.
- Regulatory bodies, code officials and procurement teams seeking to verify equivalency between ISO 8103-1 and ASME/Japanese requirements.
- Testing laboratories and certification bodies that must apply the referenced clauses when performing conformity assessments.
- Facility managers and installers planning new installations or retrofits to meet contemporary safety requirements.
