Overview

ISO/TR 22201-3:2016 is a technical report that provides a life cycle guideline for programmable electronic systems (PE systems) used in lifts (elevators), escalators and moving walks. It supplements ISO 22201‑1 (PESSRAL) and ISO 22201‑2 (PESSRAE) by specifying the content and process for the instruction manual manufacturers must provide for competent maintenance person(s). The objective is to help maintain the required safety integrity level (SIL) throughout the post‑installation life cycle (maintenance, repair, replacement, modification).

Key topics and technical requirements

• Instruction manual content: guidance on safety precautions, markings, signs and pictograms, and a checklist of elements to include (specifications, intended use, environment, restrictions, risk assessment results).
• Maintenance procedure and records: identifies required control documents (functional and production specifications, version control) and mandates recording of maintenance activities (preventative tests, failures, modifications).
• Validation of replacements/modifications: process to validate that changes do not reduce the minimum required SIL; treats changes to non‑SIL functions that interface with SIL parts with the same rigor.
• Identification and configuration management: clear identification of physical and software elements, version and configuration control, and interface documentation.
• Diagnostics, proof testing and test precautions: guidance on diagnostics, clarity about performing proof tests, and precautions to avoid introducing unintended faults during testing or via software tools.
• Environmental and operational sensitivities: address ESD, EMI, temperature, humidity and other factors that affect PE system reliability and safety.
• Verification/certification categories: outlines application tests, system certification, and function tests (field/factory) as methods to confirm conformity and SIL allocation.

Practical applications and users

ISO/TR 22201-3 is intended for:

• Manufacturers of safety components and PE systems for lifts, escalators and moving walks (to produce compliant maintenance manuals).
• Maintenance organizations and competent maintenance persons (to follow safe procedures, record actions, and validate changes).
• Owners/operators (to retain control documents and maintenance records for the life of the installation).
• Certification bodies, test laboratories and professional engineers (for witness testing and certification activities).

This guideline is especially relevant for organizations managing elevator/escalator safety, life cycle maintenance programs, and anyone responsible for maintaining SIL ratings for programmable electronic safety systems.

Related standards

• ISO 22201‑1 (PESSRAL) - Lifts (elevators)
• ISO 22201‑2 (PESSRAE) - Escalators and moving walks

• ISO 3864‑1 - Safety colours and safety signs

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
