ČSN EN IEC 60749-22-1 Tato norma poskytuje informace pro určování síly pro poruchový režim drátku, který je připevněn na povrch čipu nebo pouzdra, a který může být realizován na nezapouzdřených nebo odpouzdřených součástkách. Tato zkušební metoda může být použita pro termosonické spoje (kulička a steh) ze slitiny zlata, slitiny mědi a slitiny stříbra vytvořené drátky o průměru od 15 µm do 76 µm (0,0006" do 0,003") a ultrazvukové spoje (klín) ze slitiny zlata, slitiny mědi a slitiny hliníku vytvořené drátky o průměru od 18 µm do 600 µm (0,000 7" do 0,024"). Zkušební metoda odtržení spoje drátku je destruktivní. Je vhodná pro použití při vývoji procesů, řízení procesů nebo zajišťování kvality. Tato zkušební metoda je založena na dvou rozdílných metodách trhání drátků: a) První metoda zahrnuje použití háčku, který je umístěný pod drátek a potom je potažen. b) Druhá metoda vyžaduje, aby po utržení drátku byl tento přichycen svěrkou a připojení drátku je zkoušeno na odtržení tahem. Tato zkušební metoda stanovuje tři zkoušky tahem. Zkouška tahem pro drátek (WPT) je vhodná pro všechny připevněné drátky. Zkoušky tahem pro kuličku (BPT) a pro stehovou zkoušku (SPT) jsou vhodné pro drátky připojené termosonicky. Tato zkušební metoda nezahrnuje zkoušení pevnosti spoje použitím zkoušky smykem. Zkoušení smykem pro připojení drátku je uvedeno v IEC 60749-22-2.

ČSN P CEN/TS 17489-5 This document is intended for the use of breeder document issuing authorities both policymakers and technical, for having uniform formats that conform to printed as well as digital requirements of CEN member and associated states (including EU member states). The objectives are: - provision of a common set of formats of breeder documents - printed and digital to be implemented by CEN member and associated states (including EU member states), with the extended objective of their acceptance internationally; - the focus is on having common recognizable formats as well as prevention of identity fraud, particularly related to the use of breeder documents to obtain national and international ID documents, such as passports, and residence permits. Each country's identity management system also provides a framework for observing and protecting many of the human rights embodied in international declarations and conventions. Depending on the provisions in place, the system can ensure that citizens can exercise a wide range of rights, such as rights to property, privacy, freedom of movement and free choice of place of residence, as well as access to social services such as education, healthcare and social security. In states with more advanced technological infrastructure, population registration provides the basis for the establishment of a number of citizen-oriented computerized services, also known as e-services and e-government. Identity management is also central to prevention of discrimination in exercising guaranteed rights. The identity management infrastructure provides the backbone for a functioning and viable state by securing ci-vil, population and tax registers, as well other systems such as healthcare benefits, voter lists and the issuance of travel and identity documents based on verifiable identities. Such flaws may become visible during elections, where shortcomings in voter lists can affect confidence in the election process. In essence, a secure identity management system can be seen as the foundation, a root level, that is able to then feed into and help numerous other branches of key state services function effectively and accurately.

ČSN P CEN ISO/TS 15916 This document provides guidelines for the use of hydrogen in its gaseous and liquid forms as well as its storage in either of these or other forms (hydrides). This document identifies the basic safety concerns, hazards and risks, and describes the properties of hydrogen that are relevant to safety. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards. "Hydrogen" in this document means protium (the most common isotope of hydrogen) (1H), not deuterium (2H) or tritium (3H).

ČSN EN ISO 11295 This document establishes the steps of the overall process of pipeline rehabilitation, comprising: - strategic and tactical activities: a) investigation and condition assessment of the existing pipeline; b) pipeline rehabilitation planning. - operational activities: c) project specification; d) applications of techniques; e) documentation of the design and application process. This document defines general terms of pipeline rehabilitation and establishes the classification of families of renovation and trenchless replacement techniques, with description of their respective features. This document is applicable to underground drains and sewers and underground water and gas supply networks. This document does not apply to: - new construction provided as network extensions; - calculation methods to determine, for each viable technique, the characteristics of lining or replacement pipe material needed to secure the desired performance of the rehabilitated pipeline; - techniques providing non-structural pipe liners; - techniques for repair.

ČSN EN 71-8 ed. 2 This document specifies requirements and test methods for activity toys. This document also specifies requirements for: - separately sold accessories for, and components of activity toys; - separately sold swing elements that are ready for use on or in combination with an activity toy; - construction packages for activity toys including components used to build activity toys in accordance with a scheduled building instruction. The scope of this document excludes: - playground equipment intended for public use dealt with in the EN 1176 series; - bow-mounted rocking activity toys such as rocking horses and similar toys, which are covered by specific requirements in EN 71-1; - toy pools with maximum depth of water over 400 mm measured, between the overflow level and the deepest point within the pool; NOTE 1 - For information regarding the classification of pools as toys see European Commission guidance document No. 8 on the application of the Directive 2009/48/EC on the safety of toys - Pools [1]. - pools with maximum depth of water over 400 mm measured, between the overflow level and the deepest point within the pool, without play elements covered e.g. by the EN 16582 series or EN 16927. NOTE 2 - There is an enhanced risk of drowning in pools where the depth of water is in excess of 400 mm. - toy slides designed to be used in conjunction with domestic in-ground swimming pools; - trampolines for domestic use dealt with in EN 71-14; - powered blowers used to continuously inflate inflatable activity toys. NOTE 3 - Powered blowers used to continuously inflate inflatable activity toys are considered to be a household appliance and covered by requirements given in EN 60335-2-80. See also Clause A.1.

ČSN EN 14198 This document specifies basic requirements for the braking of trains hauled by locomotives. This document is applicable for trains hauled by locomotives and vehicles intended for use in general operation or in fixed or predefined formation. NOTE - This ensures technical compatibility of the brake function between vehicles of various origins in a train (see 5.4). If concerned, the EN-UIC brake architecture described in this document (see 5.4) is also applicable to brakes for multiple units and high-speed trains and urban rail described in the EN 16185 series and the EN 15734 series and the EN 13452 series respectively. This document also takes into account electrical and electronic control functions and additional brake systems like dynamic brakes and adhesion independent brakes. The brake system requirements, which are specific for railbound construction and maintenance machines are set out in EN 14033-1.
