This document specifies requirements for two types, seven classes and three grades of wire- or textile-reinforced dredging hoses with nominal sizes ranging from 100 to 1 200. Within each class, all grades and sizes have the same maximum working pressure. Such hoses are suitable for the delivery or suction of seawater or freshwater mixed with silt, sand, coral and small stones with a specific gravity in the range from 1,0 to 2,3 at ambient temperatures ranging from −10 °C to +40 °C.

This document covers two types of hose, as follows:

— type 1: floating type, for delivery only, which includes flotation material to give the hose buoyancy;

— type 2: submarine type for delivery and suction.

This document does not specify requirements concerning the service life of hoses or hose assemblies. Specifying such requirements is the responsibility of the customer, in consultation with the hose manufacturer.

This European Standard is applicable to all types of fans other than fans that are household appliances intended for domestic use.

NOTE 1 Fans intended for household purposes are typically used on desks, ceilings, free standing or, partitions (e.g. window and wall fans) and ducts. They are assumed to have mainly electricity related risks. These fans are in the scope of EN 60335-2-80.

It deals with all significant hazards, hazardous situations and events relevant to fans during transport, assembly and installation, commissioning and use as defined in EN ISO 12100:2010, Annex B, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see 3,24).

NOTE 2 This standard deals a.) with standalone fan units, ready for operation, complete with control systems and all other features that ensure safety in use and b.) with fans for installation (e.g. in ventilation systems) or incorporation with other equipment where control systems and all other features that ensure safety are provided by others, (details should be provided by the fan manufacturer).

This European Standard applies to electrically driven fans and, apart from the hazards related to the drives, it shall also apply to fans driven from other energy sources.

Further safety measures may be required for the additional hazards due to the application.

This European Standard does not deal with the hazards due to the use of fans in a potentially explosive atmosphere (see e.g. EN ISO 14986).

This European Standard is not applicable to fans, which are manufactured before the date of its publication.

This document specifies the definitions and requirements for single wall corrugated piping systems used in the field of non-pressure underground drainage, made out of polyethylene (PE) or polypropylene (PP)

NOTE 1 Unplasticized poly(vinyl chloride) (PVC-U) is not covered by this document because this material is not known to be used in such applications.

Products complying with this standard are intended to be used in deep burial applications where the tightness of the system is not relevant, such as collection of water from mine leachate and transversing an embankment with a culvert.

Products complying with this standard are not intended for the transport of any kind of effluents and neither for sewer applications in general (foul water / wastewater).

In conjunction with ISO/FDIS 19469-1, this document covers a range of pipe and fitting sizes, materials, pipe constructions, nominal ring stiffnesses and perforations. It is applicable to PE and PP single wall corrugated pipes and fittings, to their joints and to joints with components of other plastics and non-plastic materials.

NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

This document covers pipes and fittings sizes up to DN 1500.

NOTE 3 For dimensions larger than DN 1500, this standard may serve as general guideline.

This document specifies the definitions, general requirements and performance characteristics for single wall corrugated piping systems used in the field of non-pressure underground drainage, made of polyethylene (PE) and polypropylene (PP).

Products complying with this standard are intended to be used in applications where the tightness of the system is not relevant, such as collection of water from agricultural drainage, land drainage, water control around buildings, highway drainage, culvert drainage and surface water applications.

NOTE 1 Surface water application is understood as conveying surface water from collecting surface to sewer with smooth inside wall.

Products complying with this standard are not intended for the transport of any kind of effluents and neither for sewer applications in general (foul water/wastewater).

This document also gives guidance for the structural design of single wall corrugated pipe systems.

For most applications, single-wall corrugated pipes have perforations to allow the infiltration or exfiltration of water.

In conjunction with ISO/FDIS 19469-3, this document covers a range of pipe and fitting sizes, materials, pipe constructions, nominal ring stiffnesses, perforations and gives recommendations concerning colours.

It is applicable to polyethylene (PE) and polypropylene (PP) single wall corrugated pipes and fittings, to their joints and to joints with components of other plastics and non-plastics materials.

NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

NOTE 3 For dimensions larger than DN/ID 1500, this standard may serve as general guideline.

This International Standard provides specification and testing requirements for high pressure flexible hose assemblies intended to be connected to gas cylinders, bundles of cylinders or trailers for use when filling and emptying gas at production sites and also for customer use. This International Standard applies to flexible hose assemblies with rated pressures up to 1 000 bar for use in the temperature range of −40° C to +65° C.

This International Standard is not applicable to:

— rubber and plastics flexible hose assemblies for welding, cutting and related processes up to 45 MPa (450 bar) for customer use (see ISO 14113);

— high pressure flexible hose assemblies for use with medical gas systems for customer use (see ISO 21969);

— low pressure hose assemblies for use with medical gases, for customer use (see ISO 5359);

— rubber and thermoplastic low pressure hose assemblies for welding, cutting and related processes for customer use (see ISO 3821 or ISO 12170);

— flexible hose assemblies for cryogenic applications (see ISO 21012);

— flexible hose assemblies for liquid petroleum gas (LPG).

NOTE Flexible hose assembly designs which pass the type test approval test described in this International Standard can have a lower ratio of burst pressure to rated pressure than stated in other standards.

This European Standard specifies the requirements for the structural design of water supply pipelines, drains and sewers, and other water industry pipelines, whether operating at atmospheric, greater or lesser pressure.

In addition, this European Standard gives guidance on the application of the nationally established methods of design declared by and used in CEN member countries at the time of preparation of this European Standard.

This guidance is an important source of design expertise, but it cannot include all possible special cases, in which extensions or restrictions to the basic design methods may apply.

Since in practice precise details of types of soil and installation conditions are not always available at the design stage, the choice of design assumptions is left to the judgement of the engineer. In this connection the guide can only provide general indications and advice.

This European Standard specifies the requirements for structural design and indicates the references and the basic principles of the nationally established methods of design (see Annexes A and B).
