This draft European Standard defines a gas chromatographic analysis for the determination of the composition of fuel gases, as used in refinery heating gas. These results are used to calculate the carbon content and the lower calorific value. With this gas chromatographic analysis, an overall of 23 refinery heating gas components are determined in concentrations as typically found in refineries (see Table 1 for further details). Water is not analyzed. The results represent dry gases.
NOTE 1 Depending on the equipment used, there is a possibility to determine higher hydrocarbons as well.
NOTE 2 For the purposes of this draft European Standard, the terms “% (V/V)” is used to represent the volume fraction (φ).
IMPORTANT — This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations.

This document specifies a method for the determination of the oxidation stability of middle distillate fuels, fatty acid methyl ester (FAME) fuel and blends thereof, under accelerated conditions, by measuring the induction period to the specified breakpoint in a reaction vessel charged with the sample and oxygen.
NOTE 1 For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction (φ).
NOTE 2 The induction period is used as an indication for the resistance of middle distillates, fatty acid methyl ester (FAME) fuels and blends thereof against oxidation. This correlation can vary markedly under different conditions with different FAMEs and diesel fuel blends.
NOTE 3 The presence of ignition improvers can lead to lower oxidation stability results determined by this method. It has for instance been observed that the addition of 2-ethyl hexyl nitrate (2-EHN) can reduce the measured oxidation stability values. See [6] for details.
NOTE 4 For further information on the precision data at a test temperature of 120 °C see Annex D.

This document specifies requirements and test methods for marketed and delivered automotive liquefied petroleum gas (LPG), with LPG defined as low pressure liquefied gas composed of one or more light hydrocarbons which are assigned to UN 1011, 1075, 1965, 1969 or 1978 only and which consists mainly of propane, propene, butane, butane isomers, butenes with traces of other hydrocarbon gases.
This standard is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG.
NOTE For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction, µ, and the volume fraction, f.
WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard to health arising through inhalation of excessive amounts of LPG.
LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtures with air over the range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling, handling and testing of LPG. Naked flames, unprotected electrical equipment electrostatic hazards etc. are sources of ignition for LPG.
LPG in liquid form can cause cold burns to the skin. The national health and safety regulations apply.
LPG is heavier than air and accumulates in cavities. There is a danger of suffocation when inhaling high concentrations of LPG.
CAUTION - One of the tests described in this European Standard involves the operator inhaling a mixture of air and LPG vapour. Particular attention is drawn to the cautionary statement provided in A.1, where this method is referred to.

This document establishes the general principles for the evaluation and minimization of the effects of stray current corrosion on external surfaces of buried or immersed pipeline systems caused by AC and DC electrical interference.
Other stray current effects such as overheating, and interference with welding operations are not covered in this document.
A brief description of AC effects, general principles and some guidelines, are provided.
NOTE 1 See ISO 18086 for the effects of alternating current on buried or immersed pipelines.
Systems that can also be affected by stray currents include buried or immersed metal structures such as the following:
a) pipeline systems;
b) metal sheathed cables;
c) tanks and vessels;
d) earthing systems;
e) steel reinforcement in concrete;
f) sheet steel piling.
This document gives guidelines for
— the design of cathodic protection systems that might produce stray currents,
— the design of pipeline systems, or elements of pipeline systems, which are buried or immersed, and which can be subject to stray current corrosion, and
— the selection of appropriate protection or mitigation measures.
Internal corrosion risks from stray currents are not dealt with in detail in this document but principles and measures described here can be applicable for minimizing the interference effects.
NOTE 2 The impact of electromagnetic interference on above-ground appurtenances of pipeline systems is
covered in EN 50443, IEC 61140, IEC 60364-4-41, IEC 60479-1, IEC 60364-5-52, IEC/TS 61201 and IEC/TR 60479-5.
This document can also be used for pipeline systems outside of the petrochemical and natural gas industries and other buried or immersed structures.

This document presents general principles and gives requirements and recommendations for the assessment of the stability of non-metallic materials for service in equipment used in oil and gas exploration and production environments. This information aids in material selection. It can be applied to help avoid costly degradation failures of the equipment itself, which could pose a risk to the health and safety of the public and personnel or the environment. This document also provides guidance for quality assurance. It supplements but does not replace, the material requirements given in the appropriate design codes, standards or regulations.
This document addresses the resistance of thermoplastics to the deterioration in properties that can be caused by physical or chemical interaction with produced and injected oil and gas-field media, and with chemical treatment. Interaction with sunlight and ionizing radiation are excluded from the scope of this document.
This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.
The equipment considered includes, but is not limited to, non-metallic pipelines, piping, liners, seals, gaskets and washers.
Blistering by rapid gas decompression is not included in the scope of this document.

This document specifies requirements for the petroleum, petrochemical and natural gas industries, for producing and inspecting girth, branch and fillet welds in the pipeline part of pipeline transportation systems which meet the requirements of ISO 13623:2017 or equivalent.
NOTE 1 ISO 13847:2013 refers to the requirements of ISO 13623:2009 or equivalent. At the time of publication of this document, ISO 13623:2009 is superseded by ISO 13623:2017 and reference is made to this edition of ISO 13623 throughout this document. ISO 13623 is modified adopted as EN 14161 to exclude on-land supply systems used by the European gas supply industry from the input of gas into the on-land transmission network up to the inlet connection of gas appliances.
This document is applicable to the requirements for welding of carbon and low-alloy steel pipes, and includes guidance for the welding of corrosion-resistant alloy (CRA) and CRA-clad pipelines in Annex A. Application is restricted to pipes with a diameter of 20 mm or more and a wall thickness of 3 mm or more, a specified minimum yield strength of 555 MPa or less, and which are designed not to exceed permissible equivalent stresses as defined in ISO 13623:2017 or equivalent. It is also applicable to welding into pipelines of items such as spools, risers, launchers/receivers, fittings, flanges and pup pieces to pipeline valves. On-land supply systems used by the European gas supply industry from the input of gas into the on-land transmission network up to the inlet connection of gas appliances are excluded from the scope of this document.
Guidance for special welding applications is provided in:
