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 itemizes programming language vulnerabilities to be avoided in the development of systems where assured behaviour is required for security, safety, mission-critical and business-critical software. In general, this guidance is applicable to the software developed, reviewed, or maintained for any application. This document explains how the vulnerabilities described in the language-independent writeup, ISO/IEC 24772-1:2024 “Programming languages -- Avoiding vulnerabilities in programming languages -- Part 1: “Language-independent catalogue of vulnerabilities”, manifested in Fortran and documents mechanisms that can be used to avoid the vulnerabilities.

 

 

This document specifies the logistical and technical equipment requirements for the working environments of conference signed language interpreters. This document builds upon the existing standards on interpreters’ working environment, interpreting equipment, simultaneous interpreting delivery platforms and conference equipment ISO 17651-1, ISO 17651-2, ISO 17651-3, ISO 20109, ISO 24019 and ISO 22259.

 

ISO 16440:2016 specifies requirements, including corrosion protection, for the design, fabrication, installation and maintenance of steel-cased pipelines for pipeline transportation systems in the petroleum and natural gas industries in accordance with ISO 13623. NOTE 1 Steel casings can be used for mechanical protection of pipelines at crossings, such as at roads and railways and the installation of a casing at a highway, railway, or other crossing can be required by the permitting agency or pipeline operator. NOTE 2 This document does not imply that utilization of casings is mandatory or necessary. NOTE 3 This document does not imply that cased crossings, whether electrically isolated or electrically shorted, contribute to corrosion of a carrier pipe within a cased crossing. However, cased crossings can adversely affect the integrity of the carrier pipe by shielding cathodic protection (CP) current to the carrier pipe or reducing the CP effectiveness on the carrier pipe in the vicinity of the casing. Their use is not recommended unless required by load considerations, unstable soil conditions, or when their use is dictated by sound engineering practices.

 

This document explains how to conduct an evaluation of a cryptographic protocol implementation based on the method framework provided in ISO/IEC 15408-4.

 

This document provides guidance to enhance organizational resilience for any size or type of organization.

This document specifies the logistical and technical equipment requirements and recommendations for the working environments of signed language interpreters. This document also ensures the usability and accessibility of workspaces of signed language interpreters. It draws from, and adds to, the existing standards on interpreters’ working environment, interpreting equipment, simultaneous interpreting delivery platforms and conference equipment ISO 17651-1 [5], ISO 17651-2 [6], ISO/FDIS 17651-3 [7], ISO 20109 [8], ISO 24019 [9] and ISO 22259 [10].

 

This document specifies mechanisms for arithmetic on approximate numbers. The mechanism was first introduced in.[5] The messages are vectors of complex numbers, represented as a fixed-point type. This mechanism natively supports arithmetic between these vectors in a SIMD manner. This document also specifies parameter selection and provides numerical examples.
