This document specifies the steps of the overall process of pipeline rehabilitation, comprising: — information on strategic and tactical activities: a) investigation and condition assessment of the existing pipeline; b) pipeline rehabilitation planning. — information on and requirements for operational activities: c) project specification; d) applications of techniques; e) documentation of the design and application process. Definitions and classification of families of renovation and trenchless replacement techniques are provided, and their respective features described. Areas of application covered include underground drainage and sewerage networks and underground water and gas supply networks. The following aspects are not covered by the scope of this document: — new construction provided as network extensions; — calculation methods to determine, for each viable technique, the characteristics of lining or replacement pipe material needed to secure the desired performance of the rehabilitated pipeline; — techniques providing non-structural pressure pipe liners; — techniques for local repair. It is the responsibility of the designer to choose and design the renovation or trenchless replacement pipeline system.

This document specifies the definitions and requirements for solid-wall pipes with or without internal skin and smooth internal and external surfaces extruded from the same compound throughout the wall, fittings and the system of polyethylene (PE) piping systems to be intended for use in non-pressure underground drains and sewers for foul wastewater.

NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water.

This document is applicable to:

a) non-pressure drains and sewers, which are intended to be used buried underground outside the building structure; reflected in the marking of products by “U”;

b) non-pressure drains and sewers, which are intended to be used buried underground both outside (application area code “U”) and within the building structure, reflected in the marking of products by “UD”.

This document specifies test methods referred to in this document and test parameters.

This document is applicable to pipes and fittings with or without an integral socket.

This document covers a range of pipe and fitting sizes, stiffness classes, tolerance classes and gives recommendations concerning colours.

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.

In conjunction with CEN/TS 12666-2 [1] it is applicable to PE pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure drains an sewers.

The fittings can be manufactured by injection moulding or can be fabricated from pipes and/or mouldings.

This document is applicable to PE pipes and fittings for the following types of joints:

— elastomeric ring seal joints;

— butt fused joints;

— electrofusion joints;

— mechanical joints.

NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in the Annex D (informative) can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Clause 7 and Table 13.

This document specifies the design and operational characteristics, the safety requirements, test methods and the marking of regulators and automatic change-over devices having a maximum regulated pressure of 4 bar, with a maximum capacity of 150 kg/h, for use with butane, propane and their mixtures in the vapour phase. The maximum supply pressures for devices covered by this standard are 7,5 bar for butane and 16 bar for propane and LPG. This document also applies to the safety devices which are included within regulating devices covered by this document. This document also includes requirements for: - adaptors for connecting to self-closing valves; - integral or auxiliary safety devices. This document covers devices used in locations where the temperature likely to be reached during use is between −20 °C and +50 °C Additional requirements for devices to be used at temperatures down to −30 °C and/or up to +80 °C are defined in Annex C. This document gives special requirements for: - devices intended to be used in caravans and motor caravans (Annex D); - devices intended to be used in boats (Annex M); - specific connections which are not defined in other standards (e.g. EN 15202:2019 for cylinder valve connections). NOTE Boats considered in this document are recreational crafts covered by European Directive 2013/53/EU.

This document provides requirements to and recommendations for the periodic inspection and testing of permanently mounted tubes of: 

• Composite with seamless metallic liners,

• Composite with non-loadsharing liners,

• Seamless steel.

and large tubes of:

·  Composite with seamless metallic liners,

• Composite with non-loadsharing liners,

 including frames and associated equipment.

NOTE 1: This scope includes battery vehicles and multi-element gas containers as defined in ISO 10286 using tubes and large tubes that are permanently mounted.

This document provides a method of describing the materials, impregnates and lubricants for various types of yarn and ribbon based packings intended for use as gland seals in mechanical equipment such as pumps, mixers, etc. It does not include similar products intended for other duties such as thermal insulation. Guidance is also given regarding dimensional and physical quality aspects of the packings and requirements for packaging and marking. Tests are specified for the determination of lubricant content, size and mass. NOTE 1 The information supplied by the purchaser at the time of enquiry and/or order is given in Annex B. NOTE 2 All packings are free from introduced asbestos fibres in conformance with Annex XVII of REACH.

1.1 This International Standard specifies the requirements for seal-less rotodynamic pumps that are driven with permanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemical processes, water treatment and petrochemical industries. Their use can be dictated by space, noise, environment or safety regulations. Seal-less pumps are pumps where an inner rotor is completely contained in a pressure vessel holding the pumped fluid. The pressure vessel or primary containment device is sealed by static seals such as gaskets or O-rings. 1.2 Pumps will normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection, electromagnetic compatibility), except where special requirements are specified herein. 1.3 This International Standard includes design features concerned with installation, maintenance and operational safety of the pumps, and defines those items to be agreed upon between the purchaser and manufacturer/supplier. 1.4 Where conformity to this International Standard has been requested and calls for a specific design feature, alternative designs may be offered providing that they satisfy the intent of this International Standard and they are described in detail. Pumps which do not conform with all requirements of this International Standard may also be offered providing that the deviations are fully identified and described. Whenever documents include contradictory requirements, they should be applied in the following sequence of priority: a) purchase order (or inquiry, if no order placed), see annexes D and E; b) data sheet (see annex A) or technical sheet or specification; c) this International Standard; d) other standards.

This document specifies procedures for periodic inspection and testing, for transportable refillable LPG cylinders with a water capacity from 0,5 l up to and including 150 l. This document is applicable to the following: - welded steel LPG cylinders manufactured to an alternative design and construction, see EN 14140 or equivalent standard; - welded aluminium LPG cylinders, see EN 13110 or equivalent standard; - composite LPG cylinders, see EN 14427 or equivalent standard; - over-moulded LPG cylinders designed and manufactured according to EN 1442 or EN 14140; see Annex F. This document can also be applied to stainless steel LPG cylinders designed according to national codes, see Annex A.3. This document can also be applied to composite LPG cylinders designed according to EN 12245. This document does not apply to cylinders permanently installed in vehicles.
