Full title and description

ISO 15370:2021/Amd 1:2023 — Ships and marine technology — Low-location lighting (LLL) on passenger ships — Arrangement — Amendment 1. This amendment updates the 2021 edition of ISO 15370 and provides a short, targeted change to the arrangement guidance for low-location lighting systems used on passenger ships.

Abstract

This amendment is issued to modify ISO 15370:2021, the international standard that specifies requirements for the approval, installation and maintenance of low‑location lighting (LLL) systems as defined in SOLAS Chapter II‑2, Regulation 13.3.2.5.1, and as detailed in Chapter 11 of the International Code for Fire Safety Systems (FSS Code). The amendment document itself is brief and intended to be applied together with the full 2021 edition of ISO 15370.

General information

• Status: Published.
• Publication date: March 2023 (published 23 March 2023).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 47.020.99 (shipbuilding and marine structures / maritime safety).
• Edition / version: Amendment 1 to ISO 15370:2021 (Edition 3, 2021 — amendment text published 2023).
• Number of pages: Amendment document: 1 page; full base standard (ISO 15370:2021): 30 pages.

Scope

The amendment applies to the arrangement provisions of ISO 15370:2021 for low‑location lighting on passenger ships. The base standard itself specifies requirements for approval, installation and maintenance of LLL systems referenced in SOLAS Chapter II‑2, Regulation 13.3.2.5.1 and the FSS Code (Chapter 11); the amendment refines or corrects specific arrangement details without replacing the full standard. Users should apply the amendment together with ISO 15370:2021.

Key topics and requirements

• Arrangements for low‑location lighting (LLL) on passenger ships: placement and continuity of LLL along escape routes.
• Requirements for approval, installation and maintenance of LLL systems referenced to SOLAS and the FSS Code.
• Performance and installation considerations for electric and photoluminescent LLL systems (strip width, mounting height and location relative to deck level).
• Coordination with other safety standards and normative references (for example IEC lighting and marine equipment standards cited in ISO 15370's normative references).
• Practical editorial/technical correction(s) or clarifications introduced by Amendment 1 to ensure consistent application aboard passenger ships.

Typical use and users

Ship designers, naval architects, shipyards, classification societies, flag administrations, maritime safety officers, ship operators (particularly passenger ship operators), and manufacturers/suppliers of LLL systems use ISO 15370 and its amendment to ensure escape routes are marked and lit in compliance with SOLAS and the FSS Code and to support approval and installation processes.

Related standards

International Maritime Organization (SOLAS) Chapter II‑2 (Regulation 13 series) and the International Code for Fire Safety Systems (FSS Code, Chapter 11) are the regulatory references driving ISO 15370. ISO 15370 also references relevant IEC standards for luminaires and marine equipment (examples include IEC 60529, IEC 60598‑2‑22, IEC 60945) and IMO guidance such as A.752(18) for evaluation and testing of LLL applications.
