Overview
ISO/TR 14799-2:2023 is a technical report that provides an abbreviated comparison and expert comments on worldwide safety standards for escalators and moving walks. Published as the third edition (May 2023) by ISO/TC 178, it compares selected topics from the leading regional documents: EN 115‑1:2017 (Europe), ASME A17.1/CSA B44:2016 (North America), and the principal Japanese codes (BSLJ-EO, MOC‑N, JEAS). The report is intended to help standards writers and users understand differences, commonalities and the technical rationale behind key safety requirements - it is not a replacement for the underlying standards.
Key Topics
ISO/TR 14799-2:2023 focuses on abbreviated topic-by-topic comparisons and includes comments on:
- Terminology and definitions - harmonizing terms used differently across EN 115‑1, A17.1/B44 and Japanese codes (e.g., balustrade, skirting, moving walk terminology).
- Design and construction elements - construction and installation safety principles referenced to EN 115‑1.
- Operational parameters - rated speed, rated load and structural/supporting load considerations.
- Mechanical safety items - brake loads, auxiliary brakes, safety factors, multiplex chains.
- Guarding and panels - balustrade panelling, deck boards, comb plates and skirt-guard provisions.
- Inspection, maintenance and detection - overview of comparable detection events and inspection cover/plate requirements.
- Standards structure & technical basis - historical origins, rationale and how each code functions (mandatory vs. voluntary, performance vs. design orientation).
Notes: due to copyright limits, A17.1‑2016/CSA B44‑16 text is referenced by clause numbers rather than reproduced.
Applications
ISO/TR 14799-2 is practical for:
- Standards developers and committees seeking background and consensus points when drafting or revising national codes.
- Regulators and authorities having jurisdiction who need to understand alignment and differences between regional codes.
- Manufacturers, designers and safety engineers comparing compliance routes for international projects.
- Facility owners, inspectors and maintenance teams using the report as a roadmap to interpret which requirements overlap or diverge across jurisdictions.
Practical uses include harmonizing procurement specifications, cross-border compliance assessments, risk analyses, and informing training or inspection protocols.
