This document describes the general principles for the implementation and management of a system of cathodic protection against corrosive attacks on structures which are buried or in contact with soils, surface fresh waters or underground waters, with and without the interference of external electrical sources. It specifies the protection criteria to be achieved to demonstrate the cathodic protection effectiveness.
For structures that cannot be electrically isolated from neighbouring influencing structures, it may be impossible to use the criteria defined in the present document. In this case, EN 14505 will be applied (see 9.4 "Electrical continuity/discontinuity").
To assist in forming a decision whether or not to apply cathodic protection the corrosion likelihood can be evaluated using Annex A. Annex A summarizes the requirements of EN 12501-1 [2] and EN 12501-2 [3].
Cathodic protection of structures immersed in seawater is covered by EN 12473 and a series of standards more specific for various applications.
Cathodic protection for reinforced concrete structures is covered by EN ISO 12696.
This document is applicable in conjunction with:
-   EN ISO 15589-1 for application for buried or immersed cathodically pipelines,
-   EN 50162 to manage d.c. stray currents,
-   EN ISO 18086 to manage corrosion due to a.c. interference from high voltage power sources and a.c. traction systems,
-   EN 13509 for cathodic protection measurement techniques
-   EN 50443 to manage protection for touch and step voltage.

This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes which are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip, or a profiled plastics strip and integral locking joiner strip, and used for the renovation of underground non-pressure drainage and sewerage networks.
It applies to spirally-wound pipes of fixed or variable diameter made of profiled plastics strips, with or without steel stiffening elements, and installed by one of two methods.
The first method employs a dedicated winding machine in front of the open end of an existing pipeline, e.g. in a manhole. The pipes thus formed are simultaneously inserted into the existing pipeline by the winding forces, and by certain techniques can also be expanded in diameter after or during insertion.
The second method employs a dedicated winding machine which forms the pipe as it traverses the existing pipeline from one manhole to the next.
It applies to profiled plastics strips of unplasticized poly(vinyl chloride) (PVC U) with integral locking mechanism, or of high density polyethylene (HDPE) with integrally welded joints.

The presence of ac power supply systems or of a.c. electric traction systems (in this standard also indicated as a.c. power systems) may cause voltages to build up in pipeline systems,(in this standard indicated as interfered systems) running in the close vicinity, due to one or more of the following mechanisms:
   inductive coupling,
   conductive coupling,
   capacitive coupling.
Such voltages may cause danger to persons, damage to pipelines or connected equipment or disturbance to the electrical/ electronic equipment connected to the pipeline.
This European Standard deals with the situations where these effects may arise and with the maximum tolerable limits of the interference effects, taking into account the behaviour of the ac power systems both in normal operating condition and/or during faults.
NOTE In the worst case, the pipe may not disperse current to ground. As a consequence, the prospective touch voltage coincides with the interference voltage.
This European Standard applies to all metallic pipelines irrespective of the conveyed fluid, e.g. liquid or gas, liable to be interfered by high voltage a.c. railway and high voltage a.c. power supply systems.
The objective of this standard is to establish:
   the procedure for evaluating the e.m. interference;
   the interference distance to be considered;
   the types of coupling to be considered for operating and fault conditions of the high voltage a.c. electric traction systems and high voltage a.c. power supply systems;
   the configurations to be considered for both metallic pipeline and high voltage a.c. electric traction systems or high voltage a.c. power systems;
   the limits of the voltages due to the electromagnetic interference;
   information on interference situations, calculation methods, measuring methods, mitigation measures, management of interference.
This European Standard is applicable to all new metallic pipelines and all new high voltage a.c. electric traction systems and high voltage a.c. power supply systems and all major modifications that may change significantly the interference effect.
This European Standard only relates to phenomena at the fundamental power frequency (e.g. 50 Hz or 16,7 Hz).
This European Standard does not apply to:
   all aspects of corrosion,
   the coupling from a.c. railway and power supply systems with nominal voltages less than or equal to 1 kV,
   interference effects on the equipment not electrically connected to the pipeline.

This European Standard specifies the requirements for the application of liquid applied epoxy internal linings, for the corrosion protection of steel tubes.
This type of lining is generally used in the transport and distribution, under pressure or by gravity, of water intended for human consumption and industrial use, sea water, waste water and also in fire water. The temperature of the water transported generally does not exceed 50 °C.
The choice of the lining and its limits of use depend on the type of product used, the pipe laying conditions, the temperature and the chemical composition of the fluid. The choice of the product for the medium to be transported and its qualification are not part of this European Standard.
The lining consists normally of one layer of liquid product, applied by spray airless technique after surface preparation.
All or some of the requirements of this European Standard can apply to the internal linings of fittings, if agreed by the purchaser and the coater.
The lining in this European Standard can be applied to longitudinally or spirally welded tubes and to seamless steel tubes used for the construction of pipelines for conveying liquids.
These tubes are not intended to be bent after the epoxy lining has been applied.
This European Standard does not cover in-situ applied or rehabilitation linings.
The constituent materials of epoxy linings, when used under the conditions for which they are designed, in permanent or temporary contact with water intended for human consumption, should not change the quality of that water to such an extent that it fails to comply with the requirements of European regulations at the end user. For this purpose, reference should be made to the relevant national standards transposing EN standards when available, dealing with the influence of materials on water quality.

This document specifies requirements and test methods of foam producing solutions for leak detection (hereafter called leak detection solution) used for leak detection of combustible gases of the 1st family (town gas), 2nd family (natural gas), and 3rd family (liquefied petroleum gases (LPG)) (see EN 437) within the temperature range of -15 °C or 0 °C to 50 °C. It is applicable for leak detection solutions, which are delivered as ready to use solutions, e.g. in spray cans.
Note   The leak detection solution covered by this document may also be used for other compressed gases. In this case the producer has to be consulted.

The purpose of this standard is to define the internal and/or external coatings of polyamide powders applied by dipping in a fluidised bed or by spraying, or by roto-coating. These coatings are intended for protecting the outer and inner surface of steel tubes and their fittings (components) used as pipeline component parts. This standard may be applied for accessories (such as valves, pumps, screens, etc ... ).
This type of coating is used for the protection of buried, submerged or above ground pipelines conveying fluids at working temperatures between 0 °C and + 60 °C. Other working service temperature may be used after agreement between the purchaser and the coater.
The coatings covered by this standard are applicable to longitudinally or spirally welded steel tubes and to seamless steel tubes and their fittings components used for the construction of pipelines conveying liquids.
The internal coating of tubes to be used for the transportation of water intended for human consumption shall not affect the quality of that water to such an extent that it fails to comply with the requirements of the EU and EFTA regulations.
For this purpose, reference shall be made to the relevant national regulations and standards, transposing EN standards when available, dealing with the influence of materials on water quality and to the requirements for coatings.
NOTE   An European Acceptance Scheme (EAS) is in course of development in relation to the CPD and the DWD. Its requirements will be introduced in this standard when completed.

This European Standard specifies the application requirements and methods of test of liquid applied epoxy paints on the internal surface for the reduction of friction of tubes and pipeline fittings for conveyance of non-corrosive gas.
Other paints or paint systems are not excluded provided they comply with the requirements given in this standard.
The coating consist of one layer of liquid product, normally shop applied onto abrasive blast cleaned steel by airless spray or conventional spray techniques. Brush application may be used only for repairs.
The coating qualified in accordance with this standard is considered suitable for operating temperatures between
- 20 °C and + 110 °C.
In this European Standard the word "components" is used for tubes and fittings.

This European Standard deals with the cathodic protection against corrosion of buried or immersed metallic structures, detailing the measuring methods to be used for assessing the effectiveness of cathodic protection as well as the measurements and measures taken to monitor cathodic protection during operation.
Throughout the text, the measurement techniques are described primarily for pipelines.
However, they are sufficiently general to apply to other kinds of buried or immersed (except offshore) structures.
General principles with regard to cathodic protection are described in EN 12954. Other measurement methods specific to particular cases are described in other European Standards e.g. prEN 50162.

The standard defines the requirements of liquid applied external coating, polyurethane (PUR) and polyurethane-modified (PUR-MOD), for the corrosion protection of tubes and pipeline fittings.
The coating in this standard can be applied to longitudinally or spirally welded and to seamless steel tubes and fittings used for the construction of pipelines for conveying liquids or gases.
In accordance with the elongation properties, if the component has to be cold bent the coating shall be applied after bending unless otherwise approved by the purchaser.
The coating shall consist normally of one layer of liquid product, applied by brush or by an airless spray technique.
Other application methods can be recommended by the product manufacturer, in accordance with the kind of product (spatula, injection, spreading, etc.).
This coating can be used for the protection of buried or submerged steel tubes for service at the following temperatures and with two thickness classes A (1000 *m) and B (1500 *m) based on the following combination.
Lower thickness can be agreed between the coating manufacturer and the purchaser.
- type 1   :   - 20 °C to 40 °C, thickness class A or B
- type 2   :   - 20 °C to 60 °C, thickness class B
- type 3   :   - 20 °C to 80 °C, thickness class B
Other temperatures can be agreed; in this case, tests shall be carried out at the required temperature.
In this standard the word components is used for tubes and fittings.
Frequencies of tests on fittings shall be agreed by the parties at the ordering stage.
Components coated with these types of coatings may be further protected by means of cathodic protection.

Establishes a simple classification of the main types according to the mode of actuation of their obturation device and disregarding their details of conception and construction. Three categories of steam traps can be distinguished: mechanical traps, actuated by the level of condensate; thermostatic traps, actuated by the temperature of the condensate; thermodynamic traps, actuated by fluid dynamics.

Specifies two test methods for steam traps. The object of these tests is to determine the amount of live steam, if any, that is lost through the steam trap. There is no measurement of the total heat energy lost by the trap. Such total heat loss would include radiation and convection components which can be established separately. Figure 1 shows the test arrangement for test method A, and figure 2 shows the test arrangement for test method B.
