This document specifies requirements for, and gives guidance on, the application of life cycle costing for the development activities and operations associated with drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. This document covers facilities and associated activities within different business categories (upstream, midstream, downstream and petrochemical).
The life cycle costing process as described in this document is applicable when making decisions between competing options that are differentiated by cost and/or economic value implications. This document is not concerned with decision making related to the economic performance of individual options or options differentiated by factors other than cost or economic value.
Guidance is provided on the management methodology and application of life cycle costing in support of decision making across life cycle phases. The extent of planning and management depends on the magnitude of the costs involved, the potential value that can be created and the life cycle phase. It also provides the means of identifying cost drivers and provides a cost-control framework for these cost drivers, allowing effective cost control and optimization over the entire life of an asset.
This document specifies the procedure to be used for deposition of a weld metal pad for chemical analysis. This document applies to deposition of a weld metal pad by use of covered electrodes, wire electrodes for gas shielded metal arc welding, tubular cored electrodes for gas shielded metal arc welding and for non-gas shielded metal arc welding, solid rods and tubular cored rods for gas tungsten arc welding, and wire-flux and strip-flux combinations for submerged arc welding or electroslag welding. This document is applicable to welding consumables for non-alloy and fine grain steels, high strength steels, creep-resisting steels, stainless and heat-resisting steels, nickel and nickel alloys, and copper and copper alloys.
This document specifies a method for determining the adhesion of a bituminous emulsion coated onto aggregate when immersed in water.
The method considers two different aspects of adhesivity, i.e. immediate adhesivity and water effect on binder adhesion.
The method may be used with a reference aggregate. In that case, it measures the intrinsic adhesion behaviour of a bituminous emulsion. The method may also be used with a specific aggregate as used on a job site.

It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
This document sets out the requirements relative to the development and manufacture of food intended for sports people and food supplements to reduce the risk of the presence - without fully guarantying the absence - of substances prohibited by the World Anti-Doping Agency (WADA) [5].
This document specifies a framework of good practices with the objective of preventing the presence of substances prohibited in sport in food intended for sports people and food supplements.
This document does not lead to any form of product endorsement.
This document excludes the so-called “energy drinks”.
This European Standard specifies the common requirements and test methods, as well as the classification, marking and energy labelling of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as “boilers”.
This European Standard is to be used in conjunction with the specific Parts 2 (Part 2-1 and following ones).
This European Standard applies to boilers of types B and C.
NOTE For further background information on appliance types see CEN/TR 1749:2014 [1].
a) that use one or more combustible gases of the three gas families at the pressures stated in EN 437;
b) where the temperature of the water is below or above 105 °C during normal operation;
c) where the maximum operating pressure in the water circuit does not exceed 6 bar;
d) which can give rise to condensation under certain circumstances;
e) which are declared in the instructions for installation to be either a "condensing" boiler or a "low temperature boiler" or a "standard boiler" or an "other boiler". If no declaration is given the boiler is to be considered both a "standard boiler" and an "other boiler";
NOTE The Ecodesign Directive defines "other boilers", "low temperature boilers" and "condensing boilers". The Boiler Efficiency Directive defines "standard boilers", "low temperature boilers" and "condensing boilers". Depending on the legislation applied, a boiler can be both "a standard boiler" and an "other boiler"."
f) which are intended to be installed inside a building or in a partially protected place;
g) which are intended to produce also hot water either by the instantaneous or storage principle as a single unit.
This European Standard applies to boilers designed for sealed water systems or for open water systems.
NOTE This general standard and the specific standards (see Part 2) provide requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard or a specific standard, the risk associated with this alternative construction will need to be assessed.
An example of an assessment methodology, based upon risk assessment, is given in Clause 11.
This European Standard is not intended to cover appliances intended for connection to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex EE).
This European Standard is not intended to cover appliances designed and constructed to burn gas containing toxic components.
This document specifies safety and hygiene requirements of clipping machines (hereafter referred to as machine) for closing of casings filled with foodstuffs (hereafter referred to as product) by using a clip, and which are intended to be used in butcheries, meat processing factories, main kitchens and other food processing factories.
Clipping machines are used to close tubes with a single clip (one side) or a double clip (end locking and start locking).
The machines are equipped with closing tools (punch/die), which create the closure by deforming the locking element (clip).
This document deals with all significant hazards, hazardous situations and hazardous events relevant to machinery when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This document covers the following types of machines:
— semi-automatic machine (see Figure 1 and Figure 2);
— automatic machine (see Figure 3).
This document does not cover any machines whose closing procedure is only performed manually.
This document is not applicable to machinery manufactured before the date of publication of this document by CEN.
This European Standard specifies the characteristics and performance requirements for tubing and hoses made of either rubber or plastics for use with commercial propane and commercial butane and mixtures thereof, in the vapour phase, for connection of appliances, from:
- pressurized gas container to a regulating device,
- pressurized gas container to an appliance,
- regulating device to an appliance, and
- regulating device to installation pipework,
in environments of a temperature range from -30 °C to +70 °C. Working pressures are from 0 bar to 30 bar.
Three classes are defined in Table 1 according to the maximum working pressures and minimum ambient temperatures.
This European Standard only covers the tubing or hose part of assemblies. The assemblies themselves will be covered by EN 16436-2.
This European Standard does not apply to hoses for:
- welding purposes (see EN ISO 3821, EN 1327);
- propulsion purposes;
- LPG transfer purposes (see EN 1762).
This document specifies a procedure for carrying out impressed current electrochemical chloride extraction from chloride bearing concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement and/or post-tensioned tendon ducts embedded in concrete. In the latter case, it is essential to verify that there is no risk of hydrogen embrittlement, if necessary by conducting trials and installing monitoring during the treatment.
This document does not apply to concrete containing pre-stressing steel which can suffer hydrogen embrittlement during chloride extraction, or to concrete containing epoxy-coated or galvanized reinforcement.
In case of post-tensioned, pre-stressing concrete, the endangered tendon strands may be shielded by the tendon ducts from unwanted and/ or exceeded polarization into the cathodic range and respective water reduction.
This European Standard specifies a method for the detection of foods containing crystalline sugars which have been treated with ionizing radiation, by analysing the electron spin resonance (ESR) spectrum, also called electron paramagnetic resonance (EPR) spectrum, of the food.
Interlaboratory studies have been successfully carried out on dried figs, dried mangoes, dried papayas and raisins.
This European Standard specifies a method for the detection of foods containing cellulose which have been treated with ionizing radiation, by analysing the electron spin resonance (ESR) spectrum, also called electron paramagnetic resonance (EPR) spectrum, of the food.
Interlaboratory studies have been successfully carried out with pistachio nut shells, paprika powder and fresh strawberries. However, it has been shown that false positive results can appear when analysing bleached nuts. For further information, see Clause 7 on limitations.
