The scope of this standard is to define a nomenclature for communication of information from point-of care medical devices. Primary emphasis is placed on acute care medical devices and patient vital signs information. The nomenclature also supports concepts in an object oriented information model that is for medical device communications. This amendment extends IEEE Std 11073-10101-2019 to include additional terms primarily related to infusion pumps, ventilators, dialysis and other key medical devices as well as event and alert identifiers for devices and systems used in acute care

Specifies the requirements and the relevant tests for sterilizers intended to be used for the terminal sterilization of health care products (medical devices or medicinal products) presented as aqueous liquid in sealed containers. The container can be rigid, semi rigid or flexible. The sterilizing agent, moist heat, is created internally from the product, heating being achieved by use of saturated steam, mixtures of steam and a pressure ballasting non-condensing gas such as air or super-heated water in the sterilizer chamber. The sterilizers can be used in both a health care and industrial setting. This standard does not apply to sterilizers using saturated steam for the sterilization of the surfaces of medical devices or sterilizers used in laboratories. NOTE 1 Sterilizers using saturated steam for sterilizing the surfaces of medical devices are covered by EN 285 and EN 13060. Laboratory sterilizers are covered by some national standards. NOTE 2 Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of other aqueous liquid in sealed containers such as veterinary products or some foodstuffs. Note 3 Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of a contained product enclosed within a sterile barrier system conforming to the EN ISO 11607 series of standards.

This International Standard establishes an evaluation methodology for nuclear criticality safety with burnup credit. It identifies important parameters and specifies requirements, recommendations, and precautions to be taken into account in the evaluations. It also highlights the main important technical fields to ensure that the fuel composition or history considered in calculations provides a bounding value of the effective neutron multiplication factor, keff. A more practical approach is also presented.

This International Standard is applicable to transport, storage, disposal or reprocessing units implying irradiated fissile material from pressurized water reactor (PWR) fuels that initially contain enriched uranium oxide (UOX). Uranium could originate either from natural uranium or recycled uranium.

Fuels irradiated in other reactors (e.g. boiling water reactors) and fuels that initially contain mixed uranium-plutonium oxide are not covered in this International Standard.

This International Standard does not specify requirements related to overall criticality safety evaluation or eventual implementation of burnup credit.

This document specifies a test method for the determination of bond strength between an underlayment produced with cementitious or calciumsulfate-based floor levelling compounds and a standard substrate. This document applies to cementitious, and calcium sulphate-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.

This document specifies a calculation method to determine the thermal transmittance of glass with flat and parallel surfaces. This document applies to uncoated glass (including glass with structured surfaces, e.g. patterned glass), coated glass and materials not transparent in the far infrared which is the case for soda lime glass products, borosilicate glass, glass ceramic, alkaline earth silicate glass and alumino silicate glass. It applies also to multiple glazing comprising such glasses and/or materials. It does not apply to multiple glazing which include in the gas space sheets or foils that are far infrared transparent. The procedure specified in this document determines the U value (thermal transmittance) in the central area of glazing. The edge effects due to the thermal bridge through the spacer of an insulating glass unit or through the window frame are not included. Furthermore, energy transfer due to solar radiation is not taken into account. The effects of Georgian and other bars are excluded from the scope of this document. NOTE EN ISO 10077 1:2017 provides a methodology for calculating the overall U value of windows, doors and shutters [1], taking account of the U value calculated for the glass components according to this document. Also excluded from the calculation methodology are any effects due to gases that absorb infrared radiation in the 5 to 50 µm range. The primary purpose of this document is product comparison, for which a vertical position of the glazing is specified. In addition, U values are calculated using the same procedure for other purposes, in particular for predicting: - heat loss through glass; - conduction heat gains in summer; - condensation on glass surfaces; - the effect of the absorbed solar radiation in determining the solar factor [2]. Reference can be made to [3], [4] and [5] or other European Standards dealing with heat loss calculations for the application of glazing U values determined by this standard. Reference can be made to [6] for detailed calculations of U values of glazing, including shading devices. Vacuum Insulating Glass (VIG) is excluded from the scope of this document. For determination of the U value of VIG, please refer to EN 674 or ISO 19916-1. A procedure for the determination of emissivity is given in EN 12898. The rules have been made as simple as possible consistent with accuracy.

This document specifies a laboratory method for the extraction of microplastics from compost matrices originating from industrial or home composting. The method outlines various extraction steps assuring polymer stability, and high recovery rate. This extraction process separates microplastics from the compost matrix that can be further analysed either by number-based or by mass-based techniques.

The method is applicable for microplastics up to 1 mm in size.

The method is applicable for microplastics with densities lower than 1,4 g/cm3.

This document will not specify downstream detection methods for the identification and quantification.

The method in this document has not been validated for microplastic extraction from other matrices, except for composts.

This document defines methods that measure amounts of bacterial cells or a marker gene DNA to obtain the total abundance in environmental aqueous samples, such as seawater and river water, for biodegradability assessment. Amounts of a marker gene DNA enable to give a prediction of abundance of bacterial cells by using a conversion factor such as average number of the marker gene homologues in a bacterial cell. The methods could be also applicable to aqueous samples artificially enriched with bacterial cells released from environmental sediments. In addition, this document is applicable to solution with bacteria extracted from environmental sediments and plastic surfaces, where appropriate pre-treatment might be defined elsewhere. In the document, the method provides measurement of prokaryotic bacterial cells, though eukaryotic microorganisms are out of scope.

NOTE   Eukaryotic microorganisms, especially fungi, are well known to be primary decomposers in land, but the role in hydrosphere has been less documented and is largely unknown yet. Actually, the proportion of fungi in the ocean whole microbial metagenome has been reported as low (fungal reads make up 1,4 % to 2,9 % [2]).
