This document gives rules for improving the safety of existing escalators and moving walks with the aim of reaching an equivalent level of safety to that of a newly installed escalator and moving walk by the application of today’s state of the art for safety.

NOTE          Due to situations such as the existing machine or building designs, it may not be possible in all cases to reach today’s state of the art for safety. Nevertheless the objective is to improve the level of safety wherever possible.

This document includes the improvement of safety of existing escalators and moving walks for:

a)     users;

b)    maintenance and inspection personnel;

c)     persons outside the escalator or moving walk (but in its immediate vicinity);

d)    authorized persons.

This document is not applicable to:

a)     safety during transport, installation, repairs and dismantling of escalators and moving walks;

b)    spiral escalators;

c)     accelerating moving walks.

However, this document can usefully be taken as a reference basis.

This ECSS Engineering Standard specifies the fracture control requirements to be imposed on space segments of space systems and their related GSE.

The fracture control programme is applicable for space systems and related GSE where structural failure can result in a catastrophic hazard in accordance with the definition of ECSS-Q-ST-40 or alternative applicable document specified by the customer like those applicable to the ISS or Exploration systems or payloads.

The requirements contained in this Standard, when implemented, also satisfy the fracture control requirements applicable to the NASA and ISS.

The NASA nomenclature differs in some cases from that used by ECSS. When ISS or Exploration-specific requirements and nomenclature are included, they are identified as such.

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

This document specifies the initial and the retained performance requirements and laboratory test methods for solar powered, hardwired and communicating active road studs intended for use as permanent road marking materials.

In accordance with Low Voltage Directive 2014/35/EU, product characteristic electrical safety is applicable only to those active road studs which are designed with voltage rating between 50 and 1 000 V for alternating current and between 75 and 1 500 V for direct current. Voltage ratings refer to the voltage of the electrical input or output, not to voltages that may appear inside the equipment.

This document is to:

—    define the geometrical and non-geometrical acceptance criteria for inspection of layouts assembled whether in the fabrication plant, or trackside in the case of layouts that are delivered as components, part assembled or in “kit” form;

—    determine the extent of supply;

—    define the minimum requirements for traceability.

This document applies only to layouts that are assembled in the manufacturing plant or that are assembled for the first time at trackside.

Other aspects such as installation and maintenance also influence performance; these are not considered as part of this standard.

This document determines the interface between moveable parts and the actuation, locking and detection equipment, and defines the basic criteria for switches and crossing with moveable parts in respect of the interface.

It concerns:

—    rules, parameters and tolerances for alternative positions of the moveable parts;

—    criteria and limits for the forces which move and restrain the moveable parts.

This document provides an accepted “terminology” for switch and crossing work. With the assistance of diagrams, the various components are given definitions, and these specific names are regarded as obligatory.

The definitions cover the constituent parts and design geometry of switch and crossing work. Additional terminology of a more specific nature will be defined in the relevant part of the series.

The present definitions set out the terms most generally used for the geometrical form and the construction of switches and crossings, omitting those of too special a nature.

This document covers the following subjects:

—    the design process for switches and crossings, and the use of the other parts of this standard;

—    geometric design principles for wheel guidance;

—    definition of basic limits of supply;

—    applied forces and their adequate support;

—    tolerance levels.

These are illustrated herein by application to a turnout. The main switch and crossing components are represented in turnouts and the principles used in turnouts apply equally to more complex layouts.

This document defines the main wheel/track interaction criteria to be taken into account during the geometrical design of switches and crossings (S&C) layouts.

It specifies:

—    characterization of wheel and track dimensions;

—    geometric design principles for wheel guidance;

—    design principles for wheel load transfer;

—    whether movable crossings are needed.

These are illustrated by their application to turnout components:

—    switches;

—    crossings;

—    check rails,

but the principles apply equally to more complex layouts. There are also simplified definitions of the safety and functional dimensions, which can be used in conjunction with the general principles as the basis for more in-depth assessment.

This document defines the minimum requirements to ensure the interoperability of hydrogen refuelling points, including refuelling protocols that dispense gaseous hydrogen to road vehicles (e.g. Fuel Cell Electric Vehicles) that comply with legislation applicable to such vehicles.

The safety and performance requirements for the entire hydrogen fuelling station, addressed in accordance with existing relevant European and national legislation, are not included in this document.

NOTE          Guidance on considerations for hydrogen fuelling stations is provided in ISO 19880-1.
