Aluminium and aluminium alloys - Terms and definitions - Part 1: General terms

This European Standard defines general terms relating to products of aluminium and aluminium alloys which are helpful for communication within the aluminium industry and with its customers . It includes terms dealing with aluminium products, processing, sampling and testing, product characteristics and different types of visual quality characteristics. It does not include terms dealing with bauxite mining, alumina and anode production and aluminium smelting. This European Standard tries to adhere as closely as possible to the terms and definitions used in other standards or documents. NOTE For materials other than aluminium, different definitions can apply to terms which are defined in this document. This European Standard tries to follow the "common language" as it is used in native English speaking countries, without giving preference to specific idioms of any one of these counties. In cases where in different English-speaking countries different terms are used for the same concept or different concepts refer to an identical term, the appropriate explanations are given.

Organo-mineral fertilizers - Extraction of phosphorus by formic acid

This document specifies the procedure for the extraction of different organic and organo-mineral fertilizers with 2 % formic acid (20 g/l) to enable a subsequent determination of phosphorus, representing the amount of soft natural phosphates. 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.

Metallic materials - Unified method of test for the determination of quasistatic fracture toughness (ISO 12135:2021, including corrected version 2022-08)

This document specifies methods for determining fracture toughness in terms of K, δ, J and R-curves for homogeneous metallic materials subjected to quasistatic loading. Specimens are notched, precracked by fatigue and tested under slowly increasing displacement. The fracture toughness is determined for individual specimens at or after the onset of ductile crack extension or at the onset of ductile crack instability or unstable crack extension. In cases where cracks grow in a stable manner under ductile tearing conditions, a resistance curve describing fracture toughness as a function of crack extension is measured. In some cases in the testing of ferritic materials, unstable crack extension can occur by cleavage or ductile crack initiation and growth, interrupted by cleavage extension. The fracture toughness at crack arrest is not covered by this document. Special testing requirements and analysis procedures are necessary when testing weldments, and these are described in ISO 15653 which is complementary to this document. Statistical variability of the results strongly depends on the fracture type, for instance, fracture toughness associated with cleavage fracture in ferritic steels can show large variation. For applications that require high reliability, a statistical approach can be used to quantify the variability in fracture toughness in the ductile-to-brittle transition region, such as that given in ASTM E1921. However, it is not the purpose of this document to specify the number of tests to be carried out nor how the results of the tests are to be applied or interpreted.

Method to calculate GHG emissions at LNG plant (ISO 6338:2023)

This document provides a method to calculate the GHG emissions from an LNG liquefaction plant, onshore or offshore. The frame of this document ranges from the inlet flange of the LNG plant’s inlet facilities up to and including the offloading arms to truck, ship or railcar loading. The upstream supply of gas up to the inlet flange of the inlet facilities and the distribution of LNG downstream of the loading arms are only covered in general terms. This document covers: —     all facilities associated with producing LNG, including reception facilities, condensate unit (where applicable), pre-treatment units (including but not limited to acid gas removal, dehydration, mercury removal, heavies removal), LPG extraction and fractionation (where applicable), liquefaction, LNG storage and loading, Boil-Off-Gas handling, flare and disposal systems, imported electricity or on-site power generation and other plant utilities and infrastructure (e.g. marine and transportation facilities). —     natural gas liquefaction facilities associated with producing other products (e.g. domestic gas, condensate, LPG, sulphur, power export) to the extent required to allocate GHG emissions to the different products. —     all GHG emissions associated with producing LNG. These emissions spread across scope 1, scope 2 and scope 3 of the responsible organization. Scope 1, 2 and 3 are defined in this document. All emissions sources are covered including flaring, combustion, cold vents, process vents, fugitive leaks and emissions associated with imported energy. The LNG plant is considered “under operation”, including emissions associated with initial start-up, maintenance, turnaround and restarts after maintenance or upset. The construction, commissioning, extension and decommissioning phases are excluded from this document but can be assessed separately. The emissions resulting from boil-off gas management during loading of the ship or any export vehicle are covered by this document. The emissions from a ship at berth, e.g. mast venting are not covered by this document. This document describes the allocation of GHG emissions to LNG and other hydrocarbon products where other products are produced (e.g. LPG, domestic gas, condensates, sulphur, etc.). This document defines preferred units of measurement and necessary conversions. This document also recommends instrumentation and estimations methods to monitor and report GHG emissions. Some emissions are measured and some are estimated. This document is applicable to the LNG industry. Applications include the provision of method to calculate GHG emissions through a standardized and auditable method, a means to determine their carbon footprint.

Emergency and danger systems - Part 3: Emergency and danger response systems (EDRS) - Risk management file and examples for applications

This document specifies the structure, construction, content and sequence of a technical risk management process and the technical risk management file in accordance with EN 50726-1. It also describes application examples for technical risk management according to EN 50726-1. An emergency and danger response system (EDRS) is used to minimize risks to life and limb. Its purpose is to report, verify and manage emergencies and dangers in order to prevent or limit personal injury. As already mentioned in the scope of application of EN 50726-1, the implementation of the Occupational Safety and Health Act and the subsequent regulations is intended in order to take particular account of the protection objective defined therein (physical integrity). However, this not only includes a risk assessment (e.g. prevention of acts of violence) for employees, but also for everyone in the property. The requirements of the Occupational Safety and Health Act are therefore intended to be observed when creating a safety concept and as part of the technical risk management process. Consequently, particular attention is drawn to paragraphs 5, 6 and 9 of the Occupational Safety and Health Act. Risks to life and limb can include emergencies and dangerous situations that can cause psychological or physical harm to people. As soon as the top management (e.g. operators, entrepreneurs, companies, approving authorities, building authorities, administrations) of a property has identified such risks to life and limb as part of risk management or similar risk assessments and/or independently became aware of them, this falls within the scope of EN 50726-1.
