This document defines the following elements for urban rail rolling stock:

— the functional requirements for a communication device between passengers and driver or Operations Control Centre (OCC);

— the dynamic behaviour of the Communication device.

This document is applicable to the categories I to III of Urban Rail rolling stock defined in CEN/CLC Guide 26:

— (I) Metros;

— (II) Trams;

— (III) Light Rail.

NOTE 1 CEN/CLC Guide 26 defines Metro, Tram and Light Rail as public transport systems permanently guided at least by one rail, intended for the operation of local, urban and suburban passenger services with self-propelled vehicles and operated either segregated or not from general road and pedestrian traffic.

This document applies to rolling stock both with and without driver.

NOTE 2 The communication device is different from the PAS, but it can share some parts of the PAS to achieve its functionalities.

NOTE 3 The PAS is regarded as a safety relevant system whereas communication device is non-safety relevant aid to passengers.

This document specifies the minimum requirements for the molten metal and resin socketing of steel wire ropes within the scopes of EN 12385-4:2002+A1:2008, EN 12385-5:2002, EN 12385-6:2004, EN 12385-7:2002, EN 12385-8:2002, EN 12385-9:2002 and EN 12385-10:2003+A1:2008.

The document is applicable only to those requirements that ensure that the socketing is strong enough to withstand a force of at least 100 % of the minimum breaking force of the rope (i.e. socket termination efficiency factor KT = 1,0).

NOTE Rope terminations made by socketing in accordance with this document can be used for determining the breaking force of wire ropes in accordance with EN 12385-1:2002+A1:2008, Annex A.

Socketing by the methods and materials described in this standard are for use within the temperature limits given in normative Annex E.

This document deals with all significant hazards, hazardous situations and events relevant to metal and resin socket terminations, when they are used as intended and under conditions of misuse which are reasonably foreseeable (see Clause 4).

This document specifies the technical requirements to minimize the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of AFE when used as intended, including misuse reasonably foreseeable by the manufacturer, when carried out in accordance with the specifications given by the manufacturer or his authorized representative. It also takes into account some performance requirements recognized as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines, airports and fuelling companies.

This document applies to all types of aircraft fuelling equipment:

a) aircraft refuellers;

b) hydrant dispensers;

c) defuellers;

d) hydrant pit servicing vehicles;

e) pit cleaner vehicles;

f) stationary dispensing units,

intended to service aircraft with aviation fuels and to be operated on airfields, heliports and other aircraft refuelling related areas such as maintenance bases.

This document does not apply to:

g) AFE whose only power source for aircraft refuelling is directly applied manual effort;

h) hydrant systems, tank farms, pipework and underground tanks;

i) specific hazards due to the operation of the AFE in a potentially explosive atmosphere;

j) built-in fire extinguisher systems.

No extra requirements on noise and vibration are provided other than those in EN 1915-3 and EN 1915-4.

NOTE EN 1915-3 and EN 1915-4 provide the general GSE vibration and noise requirements.

This document does not deal with hazards in respect to a standard automotive chassis and from other vehicles on the apron.

This document is not applicable to AFE which are manufactured before the date of publication of this document by CEN.

This part of the EN 12312 series when used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4 provides the requirements for AFE.

This document specifies a laboratory substitution method to determine the insertion loss without flow of ducted, mainly absorbent, circular and rectangular silencers, as well as other duct elements for use in ventilating and air-conditioning systems.

NOTE 1 Laboratory measurement procedures for ducted silencers with superimposed flow are described in ISO 7235.

This document is applicable to silencers where the design velocity does not exceed 15 m/s. As the method does not include self-generated flow noise, this document is not suitable for tests on silencers where this type of noise is of great importance for the evaluation of the silencer performance. As most silencers, particularly in offices and dwelling, have design velocities below 15 m/s this document can often be a cost efficient alternative to ISO 7235.

The insertion loss determined according to this document in a laboratory will not necessarily be the same as the insertion loss that will be obtained in an installation in the field. Different sound and flow fields in the duct will yield different results. In this document the sound field will be dominated by plane wave modes. As this document requires regular test ducts, the results may include some flanking transmission via structural vibrations in the duct walls, that sets an upper limit to the insertion loss that can be determined.

NOTE 2 ISO 7235 gives methods for determining this limit.

This document is intended to be used for circular silencers with diameters of 80 mm to 2000 mm or rectangular silencers with cross-sectional areas within the same range.

This part of ISO 3691 gives safety requirements and the means for their verification for the following

types of pedestrian-propelled trucks (hereafter referred to as trucks), equipped with load-handling

devices for normal industrial duties, e.g. fork arms and platforms, or integrated attachments for special

applications:

— pedestrian-propelled straddle stackers,

— pallet stackers,

— industrial trucks with capacities not exceeding 1 000 kg with manual or electrical batterypowered

lifting,

— low-lift pallet trucks with lift height up to 300 mm and rated capacity up to 2 300 kg,

— scissor-lift pallet trucks with lift heights up to 1 000 mm or rated capacity up to 1 000 kg with

manual or electrical battery-powered lifting.

It is applicable to trucks provided with either manual or electrical battery-powered lifting, operating on

smooth, level, hard surfaces.

NOTE On-board battery chargers are considered to be part of the truck. Attachments mounted on the loadcarrier

or on the fork arms which are removable by the user are not considered to be part of the truck.

This part of ISO 3691 deals with significant hazards, hazardous situations and events relevant to the

applicable machines when used as intended and under conditions of misuse which are reasonably

foreseeable by the manufacturer (see Annex C).

It does not establish the additional requirements for

a) climatic conditions,

b) operation in severe conditions (e.g. extreme environmental conditions such as freezer applications,

high temperatures, corrosive environments, strong magnetic fields),

c) electromagnetic compatibility (emission/immunity),

d) handling of loads the nature of which could lead to dangerous situations (e.g. molten metal,

acids/alkalis, radiating materials, especially brittle loads),

e) handling suspended loads which may swing freely handling,

f) use on public roads,

g) direct contact with foodstuffs,

h) operation on gradients or on surfaces other than smooth, level, hard surfaces,

i) lifting systems using belts,

j) lifting of persons,

k) trucks with overturning moment greater than 40 000 N·m,

l) scissor-lift trucks whose lifting is powered by external means (electric, pneumatic),

m) roll containers,

n) trucks that are intended to be towed by powered vehicles,

o) trucks designed for special applications (e.g. hospitals, restaurant trolleys),

p) winch-operated trucks,

q) mobile lifting tables.

Hazards relevant to noise, vibration and visibility are not significant and are not dealt with in this
