ČSN EN 17333-4 This document specifies test methods for the evaluation of the mechanical properties for moisture curing, self-curing activatable or water drying foams dispensed from single pressurized foam containers. This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. The following test methods are described: - Method 1 - Compression strength: This test method describes how to determine the compressive strength of a cured foam. It gives an indication of the foams resistance against area distributed pressure. The maximum endurable stress is determined. - Method 2 - Movement capability: This test method describes how to determine the movement capability of cured foam. The result gives an indication of the degree of flexibility of the cured foam. - Method 3 - Bonding strength: The method displays the measurement of the bonding power of a One Component (Foam) Adhesive, dispensed from a pressurized foam container, between two substrates with direct contact. - Method 4 - Tensile strength: This test method describes how to determine the maximum stress a cured foam can withstand while being stretched before breaking. The result gives an indication of the elasticity of the cured foam. - Method 5 - Shear strength: This method displays the behaviour of a foam system towards shear forces. It shows the strength and the bonding power of the foam as the sandwich element between wooden plates. The test is conducted according to EN 12090.

ČSN EN 16729 This document is applicable to testing of rails installed in track for detecting rail surface cracks. This document applies to testing equipment in inspection-trains or reprofiling machines and manual systems. This document specifies the requirement for testing principles and systems in order to produce comparable results in respect to the location and the characteristic of surface cracks. This document is not aiming to give any guidelines for managing the result of eddy current rail testing. This document does not define the requirements for vehicle acceptance. This document is not concerned with production testing of rails in a production plant. This document applies only to rail profiles meeting the requirements of EN 13674-1.

ČSN P CEN/TS 17073 This document will specify the interface between the e-merchant (any commercial customer sending parcels) and the first logistic operator, including both public and private carriers. For the application of this document, a cross border parcel is a parcel crossing a border into and within Europe. The interface is composed of two items: - the physical label attached on the parcel: contents, sizes, minimum requirements to guarantee the quality and efficiency of the logistic process (sorting, delivery). - the electronic exchanges between the sender and the logistic operator with the description of the data to be provided, the format of the exchanges. While designated operators of UPU have drawn up business requirements using proprietary standards and related data components, online merchants have developed open, not-for-profit standards for final delivery which are integrated into their existing supply chain management environment. NOTE 1 - The data element enables the growth of integrated, data-driven systems which support highly efficient and customer-driven cross-border ecommerce. This reflects the current trend to B-to-B-to-C delivery solutions in the European and international cross border e-commerce markets. Delivery from original source to final consumer can be split over more than one service provider. NOTE 2 - C-to-B-to-B-to-C solutions will be an extension, in particular when returns are specified. The "first C" would indicate that consumers wishing to return items, or induct items themselves, will be able to print labels following the fundamentals specified in this standard. E-merchants exchange data with logistic operators (i.e. the postal operators, but not limited to those designated to fulfil the rights and obligations of UPU member countries) to help, simplify and enable the consequential logistic and transactional tasks. The establishment of common definitions and electronic formats safeguards the reliability and decreases the overall costs by avoiding software development costs, multiple printing equipment, over-labelling during the process, and the manual sorting.

ČSN EN ISO 9170-1 ed. 2 ČSN EN ISO 9170-1 ed. 2 je technickou revizí předchozího vydání z roku 2009 a jsou v ní zavedeny podrobnosti ke značení kyslíku 93 a upřesněny obrázky pro podmínky zkoušení. Norma platí pro terminální jednotky, u kterých obsluha připojuje a odpojuje přívod stanovených medicinálních plynů u anestetických přístrojů, plicních ventilátorů nebo jiných zdravotnických přístrojů. Terminální jednotky se rovněž používají pro potrubní systémy s podtlakem. Chybné připojení může znamenat pro pacienta nebo obsluhu nebezpečí. Záměrem je zejména zajistit specifičnost sestavy terminálních jednotek pro určitý plyn a zabránit vzájemné záměně mezi různými plyny a různými přípojkami. Dbá se, aby terminální jednotky a jejich součásti byly navrženy, vyrobeny, instalovány a udržovány tak, aby vyhovovaly základním požadavkům stanoveným v této části ČSN EN ISO 9170. Norma klade zvláštní důraz na vhodnost materiálů, specifičnost pro určitý plyn, čistotu, zkoušení, identifikaci a poskytované informace. V této části ČSN EN ISO 9170 je rovněž specifikováno zajištění informací pro instalaci a následné zkoušení terminálních jednotek před použitím. Zkoušení terminálních jednotek před použitím je z hlediska bezpečnosti pacienta kritické a je zásadní, aby terminální jednotky nebyly použity, dokud jejich zkoušky podle ČSN EN ISO 7396-1 ed. 2 nejsou zcela dokončeny.

ČSN EN IEC 61163-2 This part of IEC 61163 provides guidance on RSS techniques and procedures for electrical, electronic, and mechanical components. This document is procedural in nature and is not, and cannot be, exhaustive with respect to component technologies due to the rapid rate of developments in the component industry. This document is: a) intended for component manufacturers as a guideline; a) intended for component users as a guideline to negotiate with component manufacturers on RSS requirements; b) intended to allow the planning of an RSS process in house to meet reliability requirements or to allow the re-qualification of components for specific, upgraded, environments; c) intended as a guideline to sub-contractors who provide RSS as a service. This document is not intended to provide test plans for specific components or for delivery of certificates of conformance for batches of components. The use of bi-modal Weibull analysis to select and optimize an RSS process without having to estimate the reliability and life time of all items is described.

ČSN EN ISO 28927-1 Tento dokument stanovuje laboratorní metodu měření emise vibrací přenášených na ruce na rukojetích ručních mechanizovaných úhlových a svislých brusek. Jedná se o postup typové zkoušky ke stanovení velikosti vibrací v oblastech úchopu mechanizovaného nářadí vybaveného stanoveným zkušebním kotoučem a za podmínek běhu bez zátěže. Metoda byla stanovena jen pro úlohy broušení povrchu. Při rozbrušování a hrubování se obecně vytvářejí nižší vibrace. Záměrem je, aby se výsledky používaly k porovnání různých modelů stejného typu nářadí. Tento dokument platí pro ruční nářadí (viz kapitola 5) poháněná pneumaticky nebo jinými prostředky, která jsou určena pro broušení, rozbrušování a hrubování pomocí nástrojů z pojeného brusiva, z brusiva na podložce a ze superbrusiva pro použití na všech druzích materiálů. Neplatí pro brusky s upínacím pouzdrem nebo přímé brusky. POZNÁMKA - Aby se v anglickém originálu normy předešlo nejasnostem v používání termínů "power tool" (mechanizované nářadí) a "inserted tool" (vložený nástroj), používá se v originálu tohoto dokumentu namísto termínu "power tool" termín machine (stroj).
