ČSN EN IEC 60794-1-212 Tato norma definuje zkušební postup pro zkoumání chování útlumu (změna v útlumu), pokud je optický vláknový kabel s prvky kabelu upevněnými na obou koncích podroben teplotnímu cyklování. Tato zkouška hodnotí chování útlumu kabelu ve stavu bez pohybu, který je určen například pro zakončení spojovacími prvky nebo pasivními součástkami.

ČSN EN ISO 6134 This document specifies requirements for hoses and hose assemblies made of rubber and hose fittings made of metal, which are designed to convey saturated steam and hot water condensate. This document applies to the following two types of hoses and hose assemblies: - low pressure, with a maximum working pressure of 0,6 MPa (6 bar); - high pressure, with a maximum working pressure of 1,8 MPa (18 bar). Each type is divided into two classes, having either an oil resistant or non-oil resistant cover.

ČSN EN ISO 6806 This document specifies the minimum requirements for rubber hoses and hose assemblies for use in oil burners. The following two types of hose assembly are specified: - Type 1: Hose assemblies for flux and reflux, but not for insertion between the oil burner pump and the atomizing connection; maximum working pressure 1,0 MPa (10 bar); maximum oil temperature 100 °C; - Type 2: Hose assemblies for insertion between the oil burner pump and the atomizing connection; maximum working pressure 4,0 MPa (40 bar); maximum oil temperature 100 °C. The hose assemblies specified in this document are not intended to be used, without special assessment, for purposes other than oil burner installations.

ČSN EN 13016-1 This document specifies a method for the determination of the air saturated vapour pressure (ASVP) (total vapour pressure), exerted in vacuo, by volatile, low viscosity petroleum products, components, ethanol blends up to 85 % (V/V), and feedstocks containing air. A dry vapour pressure equivalent (DVPE) can be calculated from the air containing vapour pressure (ASVP) measurement. The conditions used in the test described in this document are a vapour-to-liquid ratio of 4:1 and a test temperature of 37,8 °C. The equipment is not wetted with water during the test, and the method described is therefore suitable for testing samples with or without oxygenates; no account is taken of dissolved water in the sample. The method described is suitable for testing air saturated samples with a DVPE between 15,5 kPa and 106,0 kPa; vapour pressures outside this range can be measured, but the precision has not been determined. This document is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant Council Directive 85/536/EEC, and for ethanol-fuel blends up to 85 % (V/V) ethanol.

ČSN EN ISO 6923 This document specifies a method for the quantitative determination of monomeric diisocyanate content in coating materials, adhesives and other liquid or pasty materials. This method is suitable for the quantification of the following monomeric diisocyanates: methylene diphenyl diisocyanate (MDI, 2,4'-MDI and 4,4'-MDI), toluene diisocyanate (TDI, 2,6-TDI, 2,4-TDI), (cis/trans) isophorone diisocyanate (IPDI) and hexamethylene diisocyanate (HDI,1,6-HDI) in various matrices for concentrations ranging from 0,01 % to 2,0 % mass fraction. For higher concentrations, a suitable dilution before the derivatization with p-nitrobenzyl-N-propylamine (PNBPA) is performed. The measurements are carried out using ultra high performance liquid chromatography (UHPLC) with a multiple wavelength detector.

ČSN EN 352-2 ed. 2+A1 This document specifies requirements on construction, design, performance, marking and user information for earplugs. In particular, it specifies requirements regarding the sound attenuation of the earplugs, measured in accordance with EN ISO 4869-1:2018. This document applies to earplugs designed for users who are able to follow supplied instructions and understand the related risks, can fit the earplugs correctly and can give feedback on the performance. Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the user, the device and where possible the working environment in which the device is likely to be used (see Annex ZA and EN 458).

ČSN EN 14404-6 This document specifies requirements for knee protectors (kneeling systems (type 4)) and performance levels for use when working in a kneeling position in order to reduce injuries to the knees caused by continuous pressure and penetration. Requirements for the marking of kneeling systems and the information to be supplied by the manufacturer are given. Where protection against additional hazards is claimed, performance requirements from other standards are applicable. This document does not apply to knee protectors which are not attached to the body in use and that are medical devices or are intended for sports and motorcycles.

ČSN EN 14404-2 This document specifies requirements for wearable knee protectors (type 1) and performance levels for use when working in kneeling position in order to reduce injuries to the knees caused by continuous pressure and penetration. Requirements for the marking of wearable knee protectors and the information to be supplied by the manufacturer are given. Where protection against additional hazards is claimed, performance requirements from other standards are applicable. This document does not apply to knee protectors that are medical devices or are intended for sports and motorcycles.

ČSN EN 14404-3 This document specifies requirements for the individual combination (type 2) of knee pads with garments and performance levels for use when working in a kneeling position in order to reduce injuries to the knees caused by continuous pressure and penetration. Requirements for the marking of knee pads and garments as well as the information to be supplied by the manufacturer are given. Where protection against additional hazards is claimed, performance requirements from other standards are applicable. This document does not apply to knee protectors that are medical devices or are intended for sports and motorcycles. In this part, requirements are given for a specific combination of an individual pad and accordingly designed garment; these forms of knee protection are thus subject to a joint examination. A combination of a garment with a fixed sized knee pad pocket and fixed sized knee pad (interoperable pad) is described in EN 14404-4 and is excluded from this part. The position of type 2 knee pads in or on trousers can be fixed or adjustable. The pads consist of foam plastic or other materials that are positioned in knee pockets of the garments or permanently fastened in or on the garments.
