This document defines the general terms and basic requests for adhesive bonding and sealing work as well as the requirements placed on adhesive users (hereafter called user-companies) and represents the state of the art for organizing adhesive bonding and sealing processes in the railway industry.

This document applies for adhesive bonding and sealing adherends for:

— the development of rail vehicles and its components (pre-production),

— production of rail vehicles and its components (in-production),

— the maintenance incl. repair of rail vehicles and its components (post-production), and

— the quality assurance of production, inspection, maintenance incl. repair of rail vehicles and its components.

This document is valid for every adhesively bonded joint in railway vehicles and its components independent of the material of the adherend. It is also valid for all kinds of adhesives independent of their solidification mechanism, their strength and their deformation properties.

This document is not valid for:

— screw retention by the usage of adhesives, if a pure screw assembly of the same design is sufficient for the purpose,

— hybrid joints, if the expected function is given exclusively by another joining technology e.g. welding, screwing, riveting,

— production of vulcanizates which do not lead to adhesively bonded joints,

— production of plywood,

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.

NOTE 3 Protection of persons in case of using asphyxiant gases used in firefighting system is covered by this document, see Annex C.

This document deals with foreseeable significant hazards, hazardous situations and events relevant to strip processing lines, when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. It provides the requirements to be met by the manufacturer to ensure the safety of persons and property during transport, commissioning, use, de-commissioning and maintenance periods, as well as in the event of foreseeable failures or malfunctions that can occur in the equipment.

This European Standard 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, and include the movement of switches. 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 part of ISO 10218 specifies requirements and guidelines for the inherently safe design, protective measures and information for use of robots for an industrial environment. It describes basic hazards associated with robots and provides requirements to eliminate, or adequately reduce, the risks associated with these hazards.

This part of ISO 10218 does not address the robot as a complete machine. Noise emission is generally not considered a significant hazard of the robot alone, and consequently noise is excluded from the scope of this part of ISO 10218.

This part of ISO 10218 does not apply to undersea, defence, law enforcement, military and space robots, medical and healthcare, prosthetics and other aids for the physically impaired, service or consumer products, tele operated manipulators, and micro robots (displacement less than 1 mm).

NOTE 1 Requirements for robot systems, integration, and applications are covered in ISO 10218-2.

NOTE 2 Additional hazards can be created by specific applications (e.g. welding, laser cutting, machining). These system-related hazards need to be considered during robot system design. See ISO 10218-2.
