ČSN EN 12503-2 This European Standard specifies safety requirements (including performance requirements) for 3 types of high jump and pole vault mats used in school, training and competition (see Clause 4). This standard specifies performance and safety values for shock absorption of the mat and anti-slip characteristics of the base. NOTE: For the specific requirements of international official competitions, see appropriate international regulations.

ČSN EN 50290-2-38 This Part 2-38 of EN 50290 gives specific requirements for Polypropylene (PP) compounds to be used for the insulation of coaxial cables. It is to be read in conjunction with EN 50290 2 20, EN 50117 and other applicable product standards. Grades PP-S1 and PP-F1 correspond to materials specified in the previous version 50290-2-25. These relatively soft Polypropylene compounds have good low temperature properties and are highly stabilized. Grades PP-S2 and PP-F2 exhibit properties more typical of Polypropylene and are designed for general Coax applications where high crush resistance and superior dielectric properties are needed. Using raw material and type test data as outlined in this standard, the raw material supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application.

ČSN EN 50290-2-33 This Part 2-33 of EN 50290 gives specific requirements for Polyethylene (PE) compounds to be used for multi element metallic data cables for indoor application. The standard includes Low Density (LD), Medium Density (MD) and High Density (HD) Polyethylene compounds. It is to be read in conjunction with EN 50290 2 20, the product standard EN 50288 and other applicable product standards. Using compound and type test data as outlined in this standard, the compound supplier will have sufficient data to demonstrate compliance and warrant that the material is suitable for the specified application.

ČSN P CEN/TS 16969 This Technical Specification specifies a test method to evaluate the ability of coating materials to seal the end grain of wood against ingress of water. This procedure is relevant for joinery or wood based cladding materials whose service life can depend on the control of water penetration through the coated end-grain.

ČSN EN 16714-3 V této evropské normě jsou stanoveny termíny a definice pro termografické zkoušení.

Obsah

ČSN EN 16714-1 Tato evropská norma popisuje obecné postupy termografického nedestruktivního zkoušení. Termografické zkoušení se používá pro detekci a lokalizaci nehomogenit (např. trhlin, delaminací a vměstků) v různých materiálech (např. kompozitech, kovech a povlacích). Obvykle se používá tepelná stimulace. Výběr typu tepelné stimulace závisí na aplikaci (např. na druhu materiálu, geometrii zkoušeného objektu a typu vad, které mají být stanoveny). V této normě nejsou definována kritéria přípustnosti.

ČSN CEN/TS 16501 This Technical Specification specifies the technical, operational and maintenance requirements for Software Assurance Levels to support the demonstration of compliance with some elements of the Essential Requirements "Safety" and "Principles governing the construction of systems" of the Regulation (EC 552/2004) of the European Parliament and of the Council on the interoperability of the European Air Traffic network ("the Interoperability regulation"). This Technical Specification on Software Assurance Levels (SWAL) is intended to apply to software that is part of the EATMN, focusing only on its "ground" segment and providing a reference against which stakeholders can assess their own practices for software specification, design, development, operation, maintenance, evolution and decommissioning. Requirements in the present document which refer to "should" statements or recommendations in the normatively referenced material are to be interpreted as fully normative ("shall") for the purpose of compliance with the present document.

ČSN EN ISO 12966-3 Tato část ISO 12966 specifikuje metodu rychlé transesterifikace tuků a olejů pomocí bazické katalýzy s použitím hydroxidu trimethylsulfonia (TMSH), pro přípravu methylesterů mastných kyselin. Tato metoda je použitelná výhradně pro přípravu methylesterů tuků a olejů pomocí plynové chromatografie s kapalnou stacionární fází (GLC). Je použitelná pro všechny tuky a oleje, s výjimkou těch, které pocházejí z mléka a mléčných výrobků. K izomerizaci nenasycených mastných kyselin dochází pouze v malém rozsahu a izomerované mastné kyseliny jsou pak přítomny jen na úrovni meze stanovitelnosti. Protože dochází k izomerizaci, nedoporučuje se tato metoda pro konjugovanou kyselinu linolovou (CLA).
