ČSN EN ISO 7817-1 This document specifies concepts and principles to establish a methodology for specifying level of information need and information deliveries in a consistent way when using building information modelling (BIM). This document specifies the characteristics of different levels used for defining the detail and extent of information required to be exchanged and delivered throughout the life cycle of built assets. It gives guidelines for principles required to specify information needs. The concepts and principles in this document can be applied for a general information exchange and while in progress, for a generally agreed way of information exchange between parties in a collaborative work process, as well as for an appointment with specified information delivery. This document is applicable to the whole life cycle of any built asset, including strategic planning, initial design, engineering, development, documentation and construction, day-to-day operation, maintenance, refurbishment, repair and end-of-life.

ČSN EN ISO 10253 This document specifies a method for the determination of the inhibition of growth of the unicellular marine algae Skeletonema sp. and Phaeodactylum tricornutum by substances and mixtures contained in sea water or by environmental water samples (effluents, elutriates, etc.). The method can be used for testing substances that are readily soluble in water and are not significantly degraded or eliminated in any other way from the test medium.

ČSN EN ISO 10075-2 This document gives guidance on design principles and on design of work systems, including task and equipment design (comprising robotics and intelligent autonomous systems) and design of the workplace, as well as working conditions with the inclusion of social and organisational factors, emphasising mental workload and its effects as specified in ISO 10075-1. It applies to the design of work and use of human capacities, with the intention of providing optimal working conditions with respect to health and safety, well-being, performance and effectiveness, preventing overload as well as underload, in order to avoid impairing effects and fostering the facilitating effects described in ISO 10075-1. This document includes the design of technical, organisational and social factors only and does not apply to problems of selection or training. This document does not address problems of measurement of mental workload or its effects. This document refers to all kinds of human work activities (see ISO 10075-1), not only to those which can be described as cognitive or mental tasks in a restricted sense but also to those with a primarily physical workload. This document is applicable to all those engaged in the design and use of work systems, for example system and equipment designers, employers and workers and their representatives, where they exist. This document is applicable to the design of new work systems as well as to the redesign of existing ones undergoing substantial revision.

ČSN EN ISO 21535 This document specifies requirements for hip-joint replacement implants. With regard to safety, this document specifies requirements for intended performance, design attributes, materials, design evaluation, manufacture, sterilization, packaging, information supplied by the manufacturer and methods of test. This document applies to both total and partial hip joint replacement implants. It applies to components made of metallic and non-metallic materials. This document applies to a wide variety of hip replacement implants, but for some specific hip replacement implant types, some considerations, not specifically covered in this document, can be applicable. Further details are given in 7.2.1.2. The requirements which are specified in this document are not intended to require the re-design or re-testing of implants which have been legally marketed and for which there is a history of sufficient and safe clinical use. For such implants, compliance with this document can be demonstrated by providing evidence of the implant's sufficient and safe clinical use.

ČSN EN ISO 21536 This document specifies requirements for knee-joint replacement implants. Regarding safety, this document specifies requirements for intended performance, design attributes, materials, design evaluation, manufacture, sterilization, packaging, information supplied by the manufacturer and methods of test. This document applies to both total and partial knee joint replacement implants. It applies to these replacements both with and without the replacement of the patella-femoral joint. It applies to components made of metallic and non-metallic materials. This document applies to a wide variety of knee replacement implants, but for some specific knee replacement implant types, some considerations, not specifically covered in this document, can be applicable. Further details are given in 7.2.1.2. The requirements which are specified in this document are not intended to require the re-design or re-testing of implants which have been legally marketed and for which there is a history of sufficient and safe clinical use. For such implants, compliance with this document can be demonstrated by providing evidence of the implant's sufficient and safe clinical use.

ČSN EN ISO 23500-2 This document specifies requirements and recommendations for individual water treatment devices and water treatment systems assembled from one or more of such devices. This document is directed at the individual or company that specifies the complete water treatment system and, the supplier who assembles and installs the system. Since systems can be assembled from a number of individual water treatment devices, the provisions of this document are also directed at the manufacturers of these devices, provided that the manufacturer indicates that the device is intended to be used to supply water for haemodialysis and related therapies. This document is applicable to all devices, piping and fittings between the point at which water is delivered to the water purification system and the point of use of the purified water. Such components include but are not necessarily limited to water purification devices, online water quality monitors (such as conductivity monitors) and piping systems for the distribution of purified water. This document does not apply to - equipment used in the preparation of concentrates from powder or other highly concentrated media at a dialysis facility either for a single patient or multiple patients, - dialysis fluid supply systems that proportion water and concentrates to produce dialysis fluid, - sorbent dialysis fluid regeneration systems that regenerate and recirculate small volumes of the dialysis fluid, - dialysis concentrates, - haemodiafiltration or haemofiltration systems, - systems that process dialysers for multiple uses, and - peritoneal dialysis systems. Requirements for the ongoing monitoring of water purity in terms of chemical and microbiological quality are given in ISO 23500-3.

ČSN P CEN ISO/TS 19590 This document specifies parameters, conditions and considerations for the reliable detection, characterization and quantification of nano-objects in aqueous suspension by spICP-MS. Particle number concentration, particle mass, particle mass concentration, particle spherical equivalent diameter, and number-based size distribution are considered the main measurands, but the technique also allows for determination of the dissolved element mass fraction in the sample. This document provides general guidelines and procedures related to spICP-MS application, and specifies minimal reporting requirements.
