This document gives requirements and recommendations for the selection and qualification of carbon and low-alloy steels for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments, whose failure can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements of the appropriate design codes, standards or regulations. This document addresses the resistance of these steels to damage that can be caused by sulfide stress cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking (SOHIC) and soft-zone cracking (SZC). This document also addresses the resistance of these steels to hydrogen-induced cracking (HIC) and its possible development into stepwise cracking (SWC). This document is concerned only with cracking. Loss of material by general (mass loss) or localized corrosion is not addressed. Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions. This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see ISO 15156-1:2020, Clause 5. Annex A lists SSC-resistant carbon and low alloy steels, and A.2.4 includes requirements for the use of cast irons. This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.

This document specifies requirements and gives recommendations for assessment of the service environment, and the selection of metallic materials used in oil and gas production in H2S-containing environments, where the failure can pose a risk to the functionality of the equipment, to the health and safety of the public and personnel or to the environment. This document is not intended for application to equipment for carbon capture, utilisation and/or storage (CCUS, CCS) or downstream oil and gas (for downstream applications see ISO 17945/NACE MR0103), but the guidance and principles can be applied by the equipment user for these applications. This document addresses the selection of carbon and low alloy steels, cast irons, corrosion-resistant alloys and other alloys for resistance to damage mechanisms that are a consequence of H2S, or which are exacerbated by H2S. This includes sulphide stress cracking, hydrogen-induced cracking, stepwise cracking, stress-oriented hydrogen-induced cracking, soft-zone cracking, galvanically induced hydrogen stress cracking and stress corrosion cracking. Some of these mechanisms can also occur in environments that do not contain H2S, but these are not included in the scope of this document. These are not included in the scope of this document. Materials with established service limits, or which have a successful history of application are listed. A path for qualifying and accepting materials that are not listed is described in ISO 15156-3. NOTE H2S can also influence degradation mechanisms other than cracking, including general and localized corrosion. This document is intended primarily for equipment users and other parties that select and accept materials and equipment for service in H2S-containing environments. It stipulates when materials need to be specified to be in conformance with ISO 15156-1 or qualified in conformance with ISO 15156-3. All oil and gas production equipment categories handling H2S-containing fluids are within the scope of this document, including but not limited to: a) drilling, well construction, and well-servicing equipment; b) wells including subsurface equipment, gas lift equipment, wellheads, and tree equipment; c) flow-lines, gathering lines, field facilities, and field processing plants; d) water-handling, injection and disposal equipment; e) gas-handling and injection equipment including those used for CO2 enhanced oil recovery; f) natural gas treatment plants (for gas sweeting plants see also API RP 945); g) transportation pipelines for liquids, gases, and multi-phase fluids. Exclusions to the scope of this document are given in Table 1.

 

This document specifies the definition and classification of steels. It defines the term "steel" (see clause 3) and it classifies the steel grades as main criteria by the chemical composition into non-alloy, low-alloy and high-alloy steels. Micro-alloy steels are a subclass of low alloy steels and stainless steels are a subclass of high-alloy steels.

 

This document specifies a method for the determination of the bio-based carbon content in products, based on the 14C content measurement. This document also specifies three test methods to be used for the determination of the 14C content from which the bio-based carbon content is calculated: — method A: Liquid scintillation-counter (LSC); — method B: Accelerator mass spectrometry (AMS); and — method C: Saturated-absorption cavity ring-down (SCAR) spectroscopy. The bio-based carbon content is expressed by a fraction of sample mass or as a fraction of the total carbon content. This calculation method is applicable to any product containing carbon, including bio-composites. NOTE This document does not provide the methodology for the calculation of the biomass content of a sample, see EN 16785 1 and EN 16785 2.

 

This document specifies a method for the extraction of phosphorus soluble in neutral ammonium citrate in inorganic fertilizers.

 

This document specifies the procedure for extraction of different organic and organo-mineral fertilizers with water to enable a subsequent determination of boron (B), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), phosphorous (P) and zinc (Zn). NOTE Extracts prepared by the procedure given in this document can also be applied for determination of other elements. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

 

This document describes methods for the measurement of the insertion loss of hearing protection devices at supra-threshold levels of impulsive noise using an acoustical test fixture (ATF). The ATF is an anthropometric fixture and contains two ear simulators for the purpose of testing hearing protection devices. The standard establishes uniform instrumentation, calibration, and electroacoustic requirements including details regarding the sound field of test facilities, and the acoustical characteristics of ATFs. The procedures described utilize signals at sound levels representative of applications in which hearing protection devices are worn, ranging from 130 dB to 170 dB peak sound pressure level (SPL). These procedures are intended to provide quick, economical, and repeatable objective (not psychophysical) measurement techniques that can be used as additions or complements to the real-ear attenuation at threshold (REAT) measurement method specified in ISO 4869-1. Methods for estimating attenuation values are provided, combining the measured insertion loss with real-ear attenuation measurements of the device with deliberate active or passive sound transmission mechanisms occluded or disabled, resulting in the impulsive level-dependent attenuation (ILDA). Other metrics are defined (the impulsive A-weighted level attenuation (ILAA) and impulsive peak-level attenuation (IPLA)); these are intended for use in estimating effective SPLs when hearing protectors are worn.
