ČSN ETSI EN 319 142-1 V1.2.1 The present document specifies PAdES digital signatures. PAdES signatures build on PDF signatures specified in ISO 32000-1 [1] with an alternative signature encoding to support digital signature formats equivalent to the signature format CAdES as specified in ETSI EN 319 122-1 [2], by incorporation of signed and unsigned attributes, which fulfil certain common requirements (such as the long term validity of digital signatures) in a number of use cases. The present document specifies formats for PAdES baseline signatures, which provide the basic features necessary for a wide range of business and governmental use cases for electronic procedures and communications to be applicable to a wide range of communities when there is a clear need for interoperability of digital signatures used in electronic documents. The present document defines four levels of PAdES baseline signatures addressing incremental requirements to maintain the validity of the signatures over the long term, in a way that a certain level always addresses all the requirements addressed at levels that are below it. Each level requires the presence of certain PAdES attributes, suitably profiled for reducing the optionality as much as possible. Procedures for creation, augmentation, and validation of PAdES digital signatures are out of scope and specified in ETSI EN 319 102-1 [i.5]. Guidance on creation, augmentation and validation of PAdES digital signatures including the usage of the different attributes defined in the present document is provided in ETSI TR 119 100 [i.4]. The present document aims at supporting electronic signatures in different regulatory frameworks. NOTE - Specifically but not exclusively, PAdES digital signatures specified in the present document aim at supporting electronic signatures, advanced electronic signatures, qualified electronic signatures, electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU) No 910/2014 [i.2].

ČSN EN 13329 This document specifies characteristics, requirements and test methods for laminate floor coverings with a surface layer as defined in 3.2 to 3.5. It also specifies requirements for marking and packaging. It includes a classification system, based on EN ISO 10874, giving practical requirements for areas of use and levels of use, to indicate where laminate floor coverings will give satisfactory service and to encourage the consumer to make an informed choice. Laminate floor coverings are generally designed for floating installations and are considered for domestic and commercial levels of use, including domestic kitchens. This document does not specify requirements relating to the use in areas which are subjected to frequent wetting, such as bathrooms, laundry rooms or saunas. In general, laminate floor coverings can only be used in those areas when authorized by the manufacturer and under conditions described in the manufacturer's installation guidelines.

ČSN EN ISO 15614-13 Dokument specifikuje zkoušky postupu svařování, které mají být použity ke kvalifikaci specifikací postupů svařování (pWPS). Definuje podmínky pro provádění zkoušek a podmínky platnosti kvalifikovaného postupu svařování pro všechny zahrnuté praktické svářečské činnosti. Jsou uvedeny dvě třídy zkoušek svařovacích postupů, aby bylo možné použít širokou škálu svařovaných výrobků. Jsou označeny třídami A a B. Ve třídě A je rozsah zkoušek větší a rozsahy kvalifikace jsou více omezující než ve třídě B.

ČSN EN IEC 63203-402-3 This part of IEC 63203 specifies terms, a measurement protocol, and a test to evaluate the accuracy of wearables that measure heart rate with a photoplethysmogram (PPG) sensor. While this document can be used to measure a variety of different devices claiming to report heart rate, care will be taken when testing in countries that differentiate between heart rate and pulse rate. This measurement protocol is not intended to evaluate medical devices associated with the IEC 60601 series or ISO 80601 series.

ČSN EN 17878-2 (38 3383) This document specifies requirements and test methods for flexible, factory made, buried district heating pipe systems with plastic service pipes and bonding between the layers of the pipe assemblies. It is only applicable in conjunction with EN 17878-1. This document is applicable to pipes, fittings, their joints and to joints with components made of non-plastics materials intended to be used for district heating installations. This document is applicable to a maximum operating temperature of 80 °C and maximum operating design pressure up to 1,0 MPa for a design service life of at least 50 years. This document does not apply to cover surveillance systems. NOTE - For higher temperatures or for the transport of other fluids, for example potable water, additional requirements and testing are needed. Such requirements are not specified in this document.

ČSN EN ISO 22007-4 This document specifies a method for the determination of the thermal diffusivity of a thin solid disc of plastics in the thickness direction by the light flash method. This method is based upon the measurement of the temperature rise at the rear face of the thin-disc specimen produced by a short energy pulse on the front face. The method is applicable to homogeneous solid plastics as well as composites having an isotropic or orthotropic structure. In general, it covers materials having a thermal diffusivity, a, in the range 1 x 10-7 m2-s-1 < a < 1 x 10-4 m2-s-1. Measurements can be carried out in gaseous and vacuum environments over a temperature range from -100 °C to +400 °C.

ČSN EN ISO 10364 This document specifies methods for determining the pot life of multi-part adhesives, in order to be able to determine whether the pot life conforms to the minimum specified working life required of an adhesive. The different methods described in this document to measure the property do not necessarily provide identical results. The test methods described are suitable for assessing all multi-part adhesives, and especially epoxy based and polyurethane based adhesives, but they are not suitable for some acrylic-based adhesives.
