This document specifies the general safety requirements common to industrial furnaces and associated processing equipment (TPE).

This document deals with the significant hazards, hazardous situations or hazardous events relevant to TPE, as listed in Annex A, when TPE is used as intended and also under conditions of misuse that are reasonably foreseeable by the manufacturer.

Annex B provides a list of common industrial furnaces and associated processing equipment.

This document specifies the requirements intended to be met by the manufacturer to ensure the safety of persons and property during commissioning, start-up, operation, shut-down, maintenance periods and dismantling, as well as in the event of foreseeable faults or malfunctions that can occur in the equipment.

These general safety requirements apply to all TPE, unless an exception is given in other parts of EN 746 series dealing with specific equipment. The provisions of other parts of EN 746 that directly apply to specific types of TPE take precedence over the provisions of this document.

This document is not applicable to

—    blast furnaces, direct reduction furnaces and gas converters;

—    steam and hot water boilers;

—    fired appliances in the refining, petrochemical and chemical industries;

—    sulphur thermal reactors ("Claus plants").

As long as no other standard is applicable for thermoprocess equipment (TPE), the requirements of this standard are applicable.

This part of the EN 746 series also details the anticipated significant hazards associated with atmosphere gas systems and their use in TPE and specifies the appropriate preventative measures for the reduction or elimination of these hazards.

The pressure hazard of the piping and components covered by this standard is within the maximum pressure/size relationship of group I as described in Annex C.

This part of the EN 746 series

—    specifies the requirements to be met to ensure the safety of persons and property during installation, commissioning, start up, operation, shutdown and maintenance,

—    does not deal with the hazard of noise which is covered in prEN 746-1:2020,

—    is not applicable to generation and use of atmosphere gas in TPE and associated plant which is manufactured before the date of its publication, and

—    gives the necessary requirements for the information for use.

A TPE designed according to this part of EN 746 series does not create any potentially explosive atmosphere in the area around the TPE and is not designed to be located in an area with a potentially explosive or hazardous atmosphere.

A table of typical protective and reactive gases is given in Annex B.

This International Standard defines dimensions and specifies performance and safety requirements for traction aid winches used in forestry for assisting supported machines while going uphill and downhill (pulling and braking). It is applicable to fixed and detachable winches and their components, connections and communications, which are used with mobile and self-propelled forestry machinery as defined in ISO 6814 such as harvesters, forwarders, skidders, planting machines, machines for forest ground preparation and machines for extracting residual waste. It is also applicable to remote traction aid winch systems which are installed on a position away from the supported machine. It is not applicable to winches which are not using a controlled rope force while going downhill and winches used for skidding, hoisting operations on cranes, draglines, high lead logging, rope logging systems or yarding. This standard is intended to be applied to traction aid systems used on machines, where without use of these systems the machine would remain stationary on slopes under its independent control (see Appendix D).

Forestry machines, as defined in ISO 6814 that are used as anchor or supported machines, are not in the scope of this standard. For guidance refer to EN ISO 11850.

This document contains requirements for defining the seismic design procedures and criteria for offshore structures; guidance on the requirements is included in Annex A. The requirements focus on fixed steel offshore structures and fixed concrete offshore structures. The effects of seismic events on floating structures and partially buoyant structures are briefly discussed. The site-specific assessment of jack-ups in elevated condition is only covered in this document to the extent that the requirements are applicable.

Only earthquake-induced ground motions are addressed in detail. Other geologically induced hazards such as liquefaction, slope instability, faults, tsunamis, mud volcanoes and shock waves are mentioned and briefly discussed.

The requirements are intended to reduce risks to persons, the environment, and assets to the lowest levels that are reasonably practicable. This intent is achieved by using:

a)    seismic design procedures which are dependent on the exposure level of the offshore structure and the expected intensity of seismic events;

b)   a two-level seismic design check in which the structure is designed to the ultimate limit state (ULS) for strength and stiffness and then checked to abnormal environmental events or the abnormal limit state (ALS) to ensure that it meets reserve strength and energy dissipation requirements.

Procedures and requirements for a site-specific probabilistic seismic hazard analysis (PSHA) are addressed for offshore structures in high seismic areas and/or with high exposure levels. However, a thorough explanation of PSHA procedures is not included.

Where a simplified design approach is allowed, worldwide offshore maps, which are included in Annex B, show the intensity of ground shaking corresponding to a return period of 1 000 years. In such cases, these maps may be used with corresponding scale factors to determine appropriate seismic actions for the design of a structure.

For design of fixed steel offshore structures, further specific requirements and recommended values of design parameters (e.g. partial action and resistance factors) are included in ISO 19902, while those for fixed concrete offshore structures are contained in ISO 19903. Seismic requirements for floating structures are contained in ISO 19904, for site-specific assessment of jack-ups and other MOUs in ISO 19905 (all parts), for arctic structures in ISO 19906 and for topsides structures in ISO 19901‑3.

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.
