Klijai. Cementinių ir kalcio sulfato grindų išlyginimo mišinių bandymo metodas. Traukimosi nustatymas

This document specifies the measurement of dimensional change of set cementitious and calcium sulfate-based floor levelling compounds after mixing with a liquid, e.g. water. This document applies to cementitious and calcium sulfate-based floor levelling compounds used for the preparation of subfloors to ensure the suitability of the substrate prior to the installation of floor coverings. By using the floor levelling compound, a homogeneous layer is built up on the load-bearing substrate, to ensure consistent absorbency, evenness and strength.

Neorganinės trąšos. Tam tikrų parametrų nustatymas

This document specifies a reference to the method for the determination of the following specific parameters in inorganic fertilizers: — granulometry; — organic carbon content; — dry matter content. 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: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic 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.

The document is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature and a boiling range of at least 100 °C. The document is applicable to distillates with initial boiling points (IBP) above 100 °C and final boiling points (FBP) below 750 °C, for example, middle distillates and lubricating base stocks. The test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphtha’s, reformates, gasolines) or middle distillates like Diesel and Jet fuel. Petroleum or petroleum products containing blending components which contain heteroatoms (for example alcohols, ethers, acids, or esters) or residue are not to be analysed by this test method. NOTE For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction. WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

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.

Sveikatos informatika. Elektroninių sveikatos priežiūros įrašų audito seka (ISO 27789:2021)

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.
