ČSN EN ISO 10524-1 This document specifies the design, construction, type testing, and marking requirements for pressure regulators (as defined in 3.18) intended for the administration of medical gases and their mixtures in the treatment, management, diagnostic evaluation and care of patients or for gases used for driving surgical tools. Examples of gases include oxygen, medical air and oxygen/nitrous oxide mixtures. This document applies to pressure regulators: a) intended to be connected to cylinders by the operator; b) with integral flow-metering devices intended to be connected to cylinders by the operator; c) that are an integral part of medical equipment (e.g. anaesthetic workstations, lung ventilators, resuscitators). A pressure regulator can be provided with pressure outlet or flow outlet, and can be adjustable or pre-set. pressure regulators are intended to be fitted to refillable cylinders with a working pressure up to 30 000 kPa ( 300 bar) and can be provided with devices which control and measure the flow of the medical gas delivered.

ČSN EN 10524-2 This document specifies design, construction, type testing, and marking requirements for manifold pressure regulators (as defined in 3.7) and line pressure regulators (as defined in 3.5) intended for use in medical gas pipeline systems. Examples of gases include oxygen, medical air and oxygen/nitrous oxide mixtures. This document applies to manifold pressure regulators and line pressure regulators supplied as individual units or to the relevant components incorporated within an assembly. Manifold pressure regulators are intended to be connected to a manifold system which has a nominal inlet pressure, P1 of up to 30 000 kPa (300 bar). Line pressure regulators are intended to be connected downstream of the manifold pressure regulator with a supply pressure up to 3 000 kPa (30 bar). This document does not apply to pressure regulators for use with vacuum pipeline systems. NOTE: Requirements for pressure regulators for use with vacuum pipeline systems are covered in ISO 10079-3.

ČSN EN 17142 This document specifies characteristics, states requirements and gives test methods for modular multilayer floor coverings with an surface layer based on wood powder (as defined in 3.1). It includes a classification system, based on EN ISO 10874, giving practical requirements for areas of use and levels of use, to indicate where powder based floor coverings will give satisfactory service and to encourage the consumer to make an informed choice. It also specifies requirements for marking and packaging. Powder based floor coverings are considered for domestic and commercial levels of use.

ČSN EN 17071 This standard defines a concept for building data structures (including data elements, syntax and semantics) for type plates with a RFID transponder (including HF, UHF, NFC), 2D symbol (including Data Matrix, QR-Code) and human readable text in a consistent way.This standard also defines a minimum set of consistent data that are needed on the data carriers when multiple data carrier techniques are used on the same item.This standard also gives guidance for creating specific applications standards, to support interoperability and backward compatibility.The processes related to the usage of type plates are not in scope of this standard.

ČSN EN 17123 This document provides guidance on characterizing the modifications of the hydromorphological features of TraC waters described in EN 16503, enabling consistent comparisons of hydromorphological modification between TraC waters within a country and between different countries in Europe. Its primary aim is to assess "departure from naturalness" as a result of human pressures on TraC hydromorphology, and it suggests suitable sources of information that may contribute to describing the modification of hydromorphological features. The procedures set out in this standard will encourage the objective assessment and reporting of the variability in transitional and coastal waters, and contribute to the work needed to implement the WFD and the MSFD; however, it does not replace methods that have been developed for local assessment and reporting.

ČSN EN 4730 This document describes the application of anthropometric data for the dimensioning of aircraft passenger seats. The focus is on the use of statistical parameters of anthropometrical measurements as given in CEN ISO/TR 7250-2 and similar sources. Even if methods described in this document might be applicable for feasibility and safety issues the scope of this document is design for comfort. The aim of this document is to give advice to designers to include methods of human-centred design into the design of aircraft seats.
