Calculations of greenhouse gas (GHG) emissions throughout the liquefied natural gas (LNG) chain - Part 2: Natural gas production and transport to LNG plant (ISO 6338-2:2024)

This document provides a method to calculate the greenhouse gas (GHG) emissions during natural gas production (onshore or offshore), gas processing and gas transport to liquefied natural gas (LNG) liquefaction plant. NOTE          It can be applied to other gases as biogas or non-traditional types of natural gas. This document covers all facilities associated with producing natural gas, including: —     drilling (exploration, appraisal, and development) and production wells; —     gas gathering network and boosting stations (if any); —     gas processing facilities (if any), transport gas pipelines with compression stations (if any) up to inlet valve of LNG liquefaction plant. This document covers facilities associated with producing other products (such as, but not limited to, domestic gas, condensate, Liquefied Petroleum Gas (LPG), sulphur, power export) to the extent required to allocate GHG emissions to each product. This document covers the upstream facilities “under operation”, including emissions associated with commissioning, initial start-up and restarts after maintenance or upset. This document does not cover the exploration, construction and decommissioning phases or the losses from vegetation coverage. This document covers all GHG emissions associated with production, process and transport of natural gas to the LNG liquefaction plant. These emissions spread across scope 1, scope 2 and scope 3 of the responsible organization, as defined in ISO 6338-1. All emissions sources are covered including flaring, combustion, cold vents, process vents, fugitive leaks and emissions associated with imported energy. Gases covered include CO2, CH4, N2O and fluorinated gases. This document does not cover compensation. 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.

Chemical disinfectants - Quantitative suspension test for the evaluation of sporicidal activity of chemical disinfectants used in food, industrial, domestic and institutional areas - Test method and requirements (phase 2, step 1)

This document specifies a test method (phase 2/step 1) and the minimum requirements for sporicidal activity of chemical disinfectant products that form a homogeneous, physically stable preparation in hard water and that are used in food, industrial, domestic and institutional areas, excluding areas and situations where disinfection is medically indicated and excluding products used on living tissues except those for hand hygiene in the above considered areas. This European Standard applies at least to the following: a) processing, distribution and retailing of: 1) food of animal origin: - milk and milk products; - meat and meat products; - fish, seafood, and related products; - eggs and egg products; - animal feeds; - etc.; 2) food of vegetable origin: - beverages; - fruits, vegetables and derivatives (including sugar, distillery, etc.); - flour, milling and baking; - animal feeds; - etc.; b) institutional and domestic areas: - catering establishments; - public areas; - public transports; - schools; - nurseries; - shops; - sports rooms; - waste containers (bins, etc.); - hotels; - dwellings; - clinically non sensitive areas of hospitals; - offices; - etc.; c) other industrial areas: - packaging material; - biotechnology (yeast, proteins, enzymes, etc.); - pharmaceutical; - cosmetics and toiletries; - textiles; - space industry, computer industry; - etc. Using this European Standard, it is not possible to determine the sporicidal activity of undiluted product as some dilution is always produced by adding the inoculum and interfering substance. Products can only be tested at a concentration of 80 % or less. NOTE The method described is intended to determine the activity of commercial formulations or active substances on spores in the conditions in which they are used.

Health informatics - Audit trails for electronic health records (ISO/DIS 27789:2026)

This document specifies a common framework for audit trails for electronic health records (EHR), in terms of audit trigger events and audit data, to keep the complete set of personal health information auditable across information systems and domains. It is applicable to systems processing personal health information that create a secure audit record each time a user reads, creates, updates, or archives personal health information via the system. NOTE       Such audit records at a minimum uniquely identify the user, uniquely identify the subject of care, identify the function performed by the user (record creation, read, update, etc.), and record the date and time at which the function was performed. This document covers only actions performed on the EHR, which are governed by the access policy for the domain where the electronic health record resides. It does not deal with any personal health information from the electronic health record, other than identifiers, the audit record only containing links to EHR segments as defined by the governing access policy. It does not cover the specification and use of audit logs for system management and system security purposes, such as the detection of performance problems, application flaw, or support for a reconstruction of data, which are dealt with by general computer security standards such as ISO/IEC 15408 (all parts)[9]. Annex A gives examples of audit scenarios. Annex B gives an overview of audit log services.
