ČSN EN 15154-2 This document is a product specification, giving performance requirements for emergency safety eyewash units connected to the water supply. It is applicable to plumbed-in eyewash units only. Requirements are given in respect of the performance, installation, adjustment and marking of the eyewash units, as well as installation, operation and maintenance instructions to be given by the manufacturer.

ČSN EN 18000-2 This document specifies the control and approval of in vitro diagnostic reagents used in animal health for immunological analyses with a qualitative expression of test results. This document is applicable to diagnostic reagents, as a priority for infectious (bacterial, viral, fungal or parasitic) or prion diseases and associated animal species for which harmonization of practices in this area is needed, i.e. those for which the national, regional or international regulatory framework provides for the control of trade in animals and/or animal products and/or the definition of a health status (absence of infection) of areas, establishments or individuals. While all reagents designated by the competent authorities fall under the scope of this document, the authorities or any other animal health stakeholder can choose to derogate in specific and exceptional situations such as emerging, exotic or rare diseases. This document is not applicable to all existing diagnostic reagents, in particular those for which certain parameters described in this document cannot be validly evaluated in accordance with international requirements, due, e.g. to the absence of a specific reference method and/or accessible and duly validated reference materials (RMs). This document does not cover the step in which the user verifies a reagent (analysis method adoption).

ČSN EN IEC 63522-4 This part of IEC 63522 is used for testing along with the appropriate severities and conditions for measurements and tests designed to assess the ability of DUTs to perform under expected conditions of transportation, storage and all aspects of operational use. The object of this test is to define a standard test method for the dielectric strength test.

ČSN P CEN/TS 17489-1 This document provides an overview of a framework on breeder documents. It introduces the document structure of CEN/TS 17489 (all parts) that specifies how citizens retain the control of breeder document data and how they can use them to support identity proofing and verification. Moreover, the framework provides methodologies to assess and increase the level of trust in breeder documents. This framework specifies methods for: - defining physical and logical/digital representations of a secure breeder document (hardware based, paper-based, server-based), - securing breeder document processes, - linking the document to its legitimate holder. The following types of breeder documents are in the scope of the framework: - birth certificates, - marriage and partnership certificates, - death certificates. The following breeder documents management processes including first-time application, later-in-life registration of an identity, and content update (e.g. name-changing) are in the scope of this framework: - registration, - issuance, - renewal, - inspection/verification, - revocation. The specification of policies is out of scope.

ČSN EN ISO 294-5 This document specifies a mould (designated the type F ISO mould) for the injection moulding of plates with a preferred size of 80 mm × 120 mm, and a preferred thickness of 2 mm for single-point and multi-point data acquisition. Suitable test specimens according to ISO 20753 type A22 or B3 are then machined or stamped from the plates and used to obtain information on the anisotropy. For the design of plastic parts, this will provide upper and lower bounds for the tensile properties. Investigation of the anisotropy of materials is a special procedure intended to provide guidance in the design of mouldings for end-use applications and is not intended as a quality control tool. In the injection moulding of thermoplastic materials, the flow of molten polymer can influence the orientation of fillers such as fibreglass or the orientation of polymer chains, resulting in anisotropic behaviour. For the purposes of this document, the flow direction is defined as the direction from the gate to the far end of the mould cavity and the cross direction as the direction perpendicular to the flow direction. The type F mould is not intended to replace the type D mould used to determine the moulding shrinkage of thermoplastics.

ČSN EN 13084-6 This document deals with special requirements and performance criteria for the design of lining systems made of steel for free standing chimneys. It specifies the requirements for cylindrical steel liners as stated in EN 13084 1. This document covers the design of the following three basic types of liners located in a load bearing structure: a) base supported liner; b) sectional liner; c) top hung liner. Additionally, this document applies to single wall chimneys regarding their contact with flue gases. For simplicity, these various designs will generally be referred to herein as "liners". The mechanical requirement is not part of this document; for information, see EN 1993-3. NOTE - Liners built from prefabricated metal chimneys in accordance with EN 1856 1:2009 and EN 1856 2:2009 are installed as base supported liners with additional supports and guides as defined in this document.

ČSN EN 15761 This document specifies a method for the determination of the dimensions and of the bulk density of pre-shaped growing media. In this document, "pre-shaped growing media": - includes solid, regular shaped, stable growing media sold, or which are ready for use, as a growing medium, where the dimensions and any corners are stable; - excludes plugs; NOTE - For the determination of the dimensions and the bulk density of plugs, EN 18250:-1 applies]. - excludes solid growing media that has to be hydrated for it to form, varies in dimension with varying water content - for example, coir or peat slabs or growing bags.
