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.

Agricultural machinery - Safety - Part 6: Sprayers and liquid fertilizer distributors (ISO/DIS 4254-6:2026)

This document, to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed and self-propelled agricultural sprayers for use with plant protection products (PPP) and liquid fertilizer application, as placed on the market by the manufacturer and designed for a single operator only. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. When requirements of this document are different from those which are stated in ISO 4254-1, the requirements of this document take precedence over the requirements of ISO 4254-1 for machines that have been designed and built according to the provisions of this document. This document, taken together with ISO 4254-1, deals with significant hazards, hazardous situations and events relevant to sprayers and liquid fertilizer distributors when they are used as intended and under the conditions foreseeable by the manufacturer (see Annex A), excepting the hazards arising from: — protection of the driver against spray when spraying (see Foreword); — automatically actuated height adjustment systems; — the environment, other than noise; — moving parts for power transmission except strength requirements for guards and barriers. This document is not applicable to sprayers and liquid fertilizer distributors which are manufactured before the date of publication of this document.

Fume cupboards — Part 9: Fume cupboards, ducted with filtered internal recirculation

This document specifies characteristics concerning the design and performance requirements together with type testing and on-site testing procedures especially for ducted filtration fume cupboards (DFFCs) not described in the other parts of EN 14175. Filters in DFFCs can be specific filters or a combination of filters dependent on the characteristics of the contaminants to be removed. This part of EN 14175 is related to and refers to other parts of EN 14175 regarding definitions, technologies, testing methodologies, design factors and functional aspects and is read in conjunction with these. This standard covers the specific layout version of ducted fume cupboards with integral filtration. These devices called ducted filtration fume cupboards can be designed to partially reuse filtered air for internal dilution. Therefore, the term “hybrid” fume cupboards is sometimes used. Fume cupboards with associated filters are considered as standard fume cupboards according EN 14175 1 to EN 14175 3. NOTE Their filter requirements, description and testing are listed in Annex A for information. The requirements for fume cupboards and filters for radioactive work are described in detail in EN 14175 8. Recirculatory filtration fume cabinets which return the filtered exhaust air back into the surrounding room are not part of this document but described in prEN 17242. DFFCs are not foreseen for work with pathogens. Appropriate microbiological cabinets are described in the EN 12469 series.

Paper and board intended to come into contact with foodstuffs - Determination of colour fastness of dyed paper and board

This document describes procedures for the testing of dyed paper and board intended to come into contact with foodstuffs. Some procedures depending on the foreseeable use of the material are given. Visual evaluation against a grey scale provides grading of the bleeding. For samples having significant different sides, a migration can occur from one glass fibre to the other and could lead to wrong interpretation of the fastness of one side. It is advisable to check these samples using large sampling procedure to prevent cross contamination of the glass fibre during the migration procedure. The procedure is described in Annex A. If lower limit of detection is required, this procedure could also be used.

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.
