This document gives requirements and recommendations for the selection and qualification of CRAs (corrosion-resistant alloys) and other alloys 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 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 materials to damage that can be caused by sulfide stress cracking (SSC), stress corrosion cracking (SCC), and galvanically induced hydrogen stress cracking (GHSC). 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. This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm. The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.

Vandens kokybė. Žarninių lazdelių (Escherichia coli) ir koliforminių bakterijų skaičiavimas. 4 dalis. Žarninėms lazdelėms (Escherichia coli) taikomas membraninio filtravimo metodas, skirtas vandeniui, kuriame yra didelis foninių bakterijų kiekis

This document describes a highly specific method for the enumeration of Escherichia coli (E. coli) in water. The method is based on membrane filtration followed by culture at 44 °C on chromogenic agar medium containing an ingredient for the detection of the enzyme β-glucuronidase, and calculation of the number of target organisms in the sample[5,6,13]. Because of the high specificity of the method, this document is suitable for waters with high levels of background bacteria, such as surface waters including bathing water and wastewater provided that they contain little particulate or colloidal matter relative to the E. coli concentration. The method can be used for fresh water and, with an adaptation, for marine water. E. coli strains which do not grow at 44 °C and those that are β-glucuronidase negative, such as E. coli O157, will not be detected as E. coli by this method. This method is not applicable to the enumeration and detection of coliform bacteria other than E. coli.

This document specifies the European Standards to which products have to conform in order to support the claims for microbicidal activity which are referred to in this document. This document also specifies terms and definitions which are used in European Standards. It is applicable to products for which activity is claimed against the following microorganisms: vegetative bacteria (including mycobacteria and Legionella), bacterial spores, yeasts, fungal spores and viruses (including bacteriophages). It is intended to: a) enable manufacturers of products to select the appropriate standards to be used in order to provide data which support their claims for a specific product; b) enable users of the product to assess the information provided by the manufacturer in relation to the use for which they intend to use the product; c) assist regulatory authorities in assessing claims made by the manufacturer or by the person responsible for placing the product on the market. It is applicable to products to be used in the area of human medicine, the veterinary area and in food, industrial, domestic and institutional areas. In the area of human medicine (Working Group 1, i.e. WG 1), it is applicable to chemical disinfectants and antiseptics to be used in areas and situations where disinfection or antisepsis is medically indicated.
