This document in the series specifies a compliance test providing information on leaching of granular waste materials, sludges, soil, soil-like materials and sediments under the experimental conditions specified hereafter, and particularly a liquid to solid ratio of 2 L/kg dry matter. It applies to materials which have a particle size below 4 mm without or with size reduction. This document has been developed to investigate the leaching of inorganic and non-volatile organic substances from granular waste materials, sludges, soil, soil-like materials and sediments. It does not take into account the consequences of microbiological processes in organic degradable materials. The test procedure specified in this document produces an eluate which is subsequently characterized physically and chemically according to appropriate standard methods. This document includes two different procedures for eluate preparation prior to analysis, one procedure for non-volatile organic substances, inorganic substances and DOC and one for inorganic substances and DOC. When assessing only the leaching of inorganic substances and DOC, certain precautions are needed when assessing the leaching of organic substances can in some cases be omitted. This procedure cannot be applied to materials with a water content or such a water affinity that a good mixing of the solid with the predetermined quantity of liquid is not achievable. This procedure does not apply to materials reacting with the leachant, leading, for example, to excessive gas emission, a solidifying effect or an excessive heat release. In that case, the material can be wetted prior to carrying out the leaching test. This test cannot be used alone to determine the leaching behaviour of granular waste materials, sludges, soil, soil-like materials and sediments, as specified in EN 12920. This document does not address issues related to health and safety.

Sveikatos informatika. Įtaisų funkcinis suderinamumas. 10406 dalis. Ryšys tarp asmeninių medicinos įtaisų. Įtaiso specializavimas. Pagrindinis elektrokardiografas (EKG) (nuo 1 iki 3 EKG išvadų) (ISO/IEEE FDIS 11073-10406:2026)

Within the context of the ISO/IEEE 11073 family of standards for device communication, a normative definition of the communication between personal basic electrocardiograph (ECG) devices and managers (e.g. cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability is established in ISO/IEEE11073-10406:2012. Appropriate portions of existing standards including ISO/IEEE 11073 terminology and IEEE 11073-20601 information models are leveraged. The use of specific term codes, formats and behaviours in telehealth environments restricting optionality in base frameworks in favour of interoperability is specified. A common core of communication functionality for personal telehealth basic ECG (1- to 3-lead ECG) devices is defined. Monitoring ECG devices are distinguished from diagnostic ECG equipment with respect to support for wearable ECG devices, limiting the number of leads supported by the equipment to three, and not requiring the capability of annotating or analysing the detected electrical activity to determine known cardiac phenomena. ISO/IEEE 11073-10406:2012 is consistent with the base framework and allows multifunction implementations by following multiple device specializations (e.g. ECG and respiration rate).

Širdies ir kraujagyslių implantai bei ekstrakorporinės sistemos. Kraujagyslių protezai. Vamzdiniai kraujagyslių transplantantai ir kraujagyslių lopai (ISO/DIS 7198:2026)

ISO 7198:2016 specifies requirements for the evaluation of vascular prostheses and requirements with respect to nomenclature, design attributes and information supplied by the manufacturer, based upon current medical knowledge. Guidance for the development of in vitro test methods is included in an informative annex to ISO 7198:2016. It can be considered as a supplement to ISO 14630:2012, which specifies general requirements for the performance of non-active surgical implants. NOTE Due to the variations in the design of implants covered by ISO 7198 :2016 and, in some cases, due to the relatively recent development of some of these implants (e.g. bioabsorbable vascular prostheses, cell based tissue engineered vascular prostheses), acceptable standardized in vitro tests and clinical results are not always available. As further scientific and clinical data become available, appropriate revision of ISO 7198 :2016 will be necessary. It is applicable to sterile tubular vascular grafts implanted by direct visualization surgical techniques as opposed to fluoroscopic or other non-direct imaging (e.g. computerized tomography or magnetic resonance imaging), intended to replace, bypass, or form shunts between segments of the vascular system in humans and vascular patches intended for repair and reconstruction of the vascular system. Vascular prostheses that are made of synthetic textile materials and synthetic non-textile materials are within the scope of ISO 7198:2016. While vascular prostheses that are made wholly or partly of materials of non-viable biological origin, including tissue engineered vascular prostheses are within the scope, ISO 7198:2016 does not address sourcing, harvesting, manufacturing and all testing requirements for biological materials. It is further noted that different regulatory requirements might exist for tissues from human and animal sources. Compound, coated, composite, and externally reinforced vascular prostheses are within the scope of ISO 7198:2016. Endovascular prostheses implanted using catheter delivery and non-direct visualization are excluded from the scope of ISO 7198:2016. It includes information on the development of appropriate test methods for graft materials, referenced in ISO 25539‑1 for materials used in the construction of endovascular prostheses (i.e. stent-grafts). NOTE Requirements for endovascular prostheses are specified in ISO 25539‑1. The valve component of valved conduits constructed with a tubular vascular graft component, and the combination of the valved component and the tubular vascular graft component, are excluded from the scope of ISO 7198:2016. It can be helpful in identifying the appropriate evaluation of the tubular vascular graft component of a valved conduit but specific requirements and testing are not described for these devices. Cardiac and pericardial patches, vascular stents, accessory devices such as anastomotic devices, staplers, tunnelers and sutures, and pledgets are excluded from the scope of ISO 7198:2016. NOTE Requirements for vascular stents are specified in ISO 25539‑2. Requirements regarding cell seeding are excluded from the scope of ISO 7198:2016. Tissue engineered vascular prostheses that contain or are manufactured using cells present many distinct manufacturing (e.g. aseptic processing, cell seeding, etc.) and testing issues than those produced with synthetic or non-viable biological materials. The in vitro testing requirements that are outlined in ISO 7198:201

Vandens kokybė. Technecis 99. 2 dalis. Tyrimo metodas taikant induktyviai sužadintos plazmos masių spektrometriją (ICP-MS) (ISO/DIS 22125-2:2026)

Warning — Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices. Warning — It is absolutely essential that tests conducted in accordance with this document be carried out by suitably qualified staff. This document specifies methods to determine 99Tc by inductively coupled plasma mass spectrometry (ICPMS) in supply water, drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling, handling, and test sample preparation. The detection limit depends on the sample volume, the instrument used, the background count rate, the detection efficiency, the counting time, and the chemical yield. The detection limit of the methods described in this document, using currently available ICP-MS instrumentation, is approximately 0,2 ng·l−1 to 0,5 ng·l−1 (0,1 Bq·l−1 to 0,3 Bq·l−1), which is much lower than the WHO criteria for safe consumption of drinking water (100 Bq·l−1)[4]. The methods presented in this document are not intended for the determination of ultratrace amount of 99Tc. The methods described in this document are applicable in the event of an emergency situation, but not if 99mTc is present at quantities that could cause interference. Filtration of the test sample is necessary for the methods described in this document if suspended solids are present. The analysis of 99Tc adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is made on the different phases obtained. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.
