ČSN ETSI EN 319 401 V3.2.1 The present document specifies general policy requirements relating to trust service providers (TSPs) that are independent of the type of TSP. It defines policy requirements on the operation and management practices of TSPs. Other specifications refine and extend these requirements as applicable to particular forms of TSP. The present document does not specify how the requirements identified can be assessed by an independent party, including requirements for information to be made available to such independent assessors, or requirements on such assessors. The present document aims to support the requirements on NIS2 Directive [i.13] and addresses the general requirements for security management and cybersecurity of trust services (qualified and non-qualified). NOTE - See ETSI EN 319 403 1 [i.2] for details about requirements for conformity assessment bodies assessing Trust Service Providers.

ČSN EN ISO 18166 (05 0070) This document specifies the execution, validation, verification and documentation of a numerical welding simulation within the field of computational welding mechanics (CWM) and performed with a scientific computational tool (SCT). This document is applicable to the thermal and mechanical finite element analysis (FEA) of arc, laser and electron beam welding processes for the purpose of calculating the effects of welding processes, and in particular, residual stresses and distortion, in support of structural integrity assessment.

ČSN EN IEC 62541-22 This part of IEC 62541 specifies an OPC UA Information Model for a basic set of network related components used in other Information Models. The initial version of this document defines parameter sets for TSN Talkers and Listeners as well as network interfaces and ports as shown in Figure 1. A future version of this document is expected to have a broader scope of other network technologies than Ethernet only.

ČSN EN IEC 60115-2-10 COMMENT - The text of this clause may repeat information already given in some fields of the above title block. Essential information on the special type of components covered by the drafted detail specification may be added, preferably at the place marked with ".". This detail specification specifies the characteristics and ratings of low-power film resistors with leads for use in electronic equipment, which are typically assembled in through-hole technology (THT) on circuit boards. The resistors covered herein are classified to level G, as defined in IEC 60115-1:2020, 3.4 for general electronic equipment, typically operated under benign or moderate environmental conditions, where the major requirement is function. Examples for level G include consumer products and telecommunication user terminals. This detail specification is based upon the blank detail specification IEC 60115-2-10:2023. This detail specification establishes test schedules and performance requirements permitting the quality assessment of the resistors covered herein according to the quality assessment procedures specified by IEC 60115-1:2020, Annex Q.

ČSN EN ISO 16958 This document specifies a method for the quantification of individual and/or all fatty acids content in the profile of milk, milk products, infant formula and adult nutritional formula, containing milk fat and/or vegetable oils, supplemented or not supplemented with oils rich in long chain polyunsaturated fatty acids (LC-PUFA). This also includes groups of fatty acids often labelled [i.e. trans fatty acids (TFA), saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, omega-6 and omega-9 fatty acids] and/or individual fatty acids [i.e. linoleic acid (LA), alpha-linolenic acid (ALA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)]. The determination is performed by direct transesterification in food matrices, without prior fat extraction, and consequently it is applicable to liquid samples or reconstituted powder samples with water having total fat >= 1,5 % (mass fraction). The fat extracted from products containing less than 1,5 % (mass fraction) fat can be analysed with the same method after a preliminary fat extraction using methods referenced in Clause 2. Dairy products, such as soft or hard cheeses with acidity level

ČSN EN ISO 11300-1 This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation, by means of renovation and trenchless replacement, of underground non-pressure and pressure drains and sewers and water supply networks, which transport water intended for human consumption, including raw water pipelines. It is applicable to polyethylene (PE) pipes, fittings and assemblies, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to the following technique families for renovation, intended to be used at an operating temperature of 20 °C as the reference temperature: - lining with continuous pipes; - lining with close-fit pipes. This document is applicable to the following technique families for trenchless replacement, intended to be used at an operating temperature of 20 °C as the reference temperature: - pipe bursting and pipe extraction; - horizontal directional drilling and impact moling. When used with lining with continuous pipes, lining with close-fit pipes and trenchless replacement technique families, this document is applicable to: - PE solid wall single layered pipes (nominal outside diameter, dn), including any identification stripes; - PE pipes with co-extruded layers on either or both the outside and inside of the pipe (total outside diameter, dn), as specified in Annex D, where all layers have the same MRS rating. Furthermore, when used with lining with continuous pipes and trenchless replacement this document is applicable to: - PE coated pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe ("coated pipe"), as specified in Annex D. This document is applicable to jointing by means of butt fusion and electrofusion and to fabricated and injection-moulded fittings and mechanical connections of PE.
