What is ISO 8102‑6 - Electrical requirements for lifts, escalators, and moving walks about?
ISO 8102 discusses electrical requirements for lifts, escalators and moving walks. ISO 8102‑6 covers those aspects that need to be addressed when programmable electronic systems are used to carry out electronic safety functions for escalators and moving walks (PESSRAE).
ISO 8102‑6 is applicable for escalator and moving walk safety functions that are identified in escalator and moving walk codes, standards, or laws that reference ISO 8102‑6 for the PESSRAE application. The safety integrity levels (SILs) specified are to be valid for the PESSRAE application.
ISO 8102‑6 specifics: -
- The requirements for achieving safety integrity for a function and outlines the relationship between escalator and moving walk safety functions and their safe-state conditions
- Applies to phases and activities that are specific to the design of hardware and software and provides requirements relating to the hardware and software safety validation
- Defines a maximum level of performance (SIL 3) which can be achieved for a PESSRAE
Note: ISO 8102‑6 does not cover:
- Hazards arising from the PE systems equipment itself such as electric shock etc
- The concept of fail-safe that can be of value when the failure modes are well defined and the level of complexity is relatively low
- Other relevant requirements necessary for the complete application of a PESSRAE in an escalator and moving walk safety function, such as system integration specifications, temperature and humidity, the mechanical construction, mounting and labelling of switches, actuators, or sensors that contain PESSRAE
- Foreseeable misuse involving security threats related to malevolent or unauthorized action
Who is ISO 8102‑6 - Electrical requirements for lifts, escalators, and moving walks for?
ISO 8102‑6 on electrical requirements for lifts, escalators, and moving walks is useful for:
- Lift Manufacturers
- Escalators manufacturers
- Design engineers
- Lifts/Escalators maintenance personnel
- Quality control personnel
Why should you use ISO 8102‑6 - Electrical requirements for lifts, escalators, and moving walks?
ISO 8102‑6 intended to be by reference Harmonization within a national escalator and moving walk standards such as escalator and moving walk codes, standards, or laws.
ISO 8102‑6 sets out the product-specific requirements for systems comprising programmable electronic elements that are used to perform safety functions in escalators and moving walks.
ISO 8102‑6 has been developed so that consistent technical and performance requirements and rationale can be specified for a programmable electronic system in the safety-related application for escalators (PESSRAE) and moving walks.
