ČSN EN ISO 15753 Tato mezinárodní norma popisuje dvě metody pro stanovení 15 polycyklických aromatických uhlovodíků (PAU) v živočišných a rostlinných tucích a olejích. Obecná metoda a specifická metoda pro kokosový olej a rostlinné oleje s mastnými kyselinami s krátkým řetězcem. Tyto metody nejsou kvantitativní pro velmi těkavé sloučeniny jako naftalen, acenaften a fluoren. Vzhledem k interferencím způsobovaným samotnou matricí, nemůže být palmový olej a olivový olej z pokrutin analyzován pomocí této metody.

ČSN EN ISO 16409 This International Standard specifies requirements and test methods for performance criteria for manual interdental brushes with a round cross-section of the brush head and consisting of a wired stem with inserted filaments. It also specifies the accompanying information such as manufacturer's instructions for use and labelling of the packaging. Excluded are interdental brushes with a plastic core. This International Standard is not applicable to powered interdental brushes, manual toothbrushes, dental floss, tapes, and strings and to interdental cleaners that do not include filaments.

ČSN EN ISO 3964 This International Standard specifies the coupling between handpieces and motors connected to dental units. This International Standard specifies the nominal dimensions, tolerances and the extraction force of coupling systems for use between handpiece and motor which supply the handpiece with water, air and light and rotation energy.

ČSN EN ISO 14801 This International Standard specifies a method of dynamic testing of single post endosseous dental implants of the transmucosal type in combination with their premanufactured prosthetic components. It is most useful for comparing endosseous dental implants of different designs or sizes. This International Standard is not a test of the fundamental fatigue properties of the materials from which the endosseous implants and prosthetic components are made. This International Standard is not applicable to dental implants with endosseous lengths shorter than 8 mm nor to magnetic attachments. While this International Standard simulates the functional loading of an endosseous dental implant under "worst case" conditions, it is not applicable for predicting the in vivo performance of an endosseous dental implant or dental prosthesis, particularly if multiple endosseous dental implants are used for a dental prosthesis.

ČSN ETSI EN 301 489-15 V2.1.1 The present document, together with ETSI EN 301 489 1 [1], covers the assessment of commercially available amateur radio equipment, and associated ancillary equipment, in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of commercially available amateur radio equipment are not included in the present document. Such technical specifications are found in the relevant product standard ETSI EN 301 783 [i.2] for the effective use of the radio spectrum. The present document specifies the applicable EMC tests, the methods of measurement, the limits and the performance criteria for radio equipment intended for use by radio amateurs within the meaning of article 1, definition 53 of the Radio Regulations [i.3] and associated ancillary equipment, which is commercially available. Examples of amateur radio equipment covered by the present document are given in annex B. The provisions of the present document apply to amateur radio equipment manufactured commercially either as ready to-use equipment, modules, or components having an intrinsic functionality for the customer. The expression "amateur radio equipment" in the context of the present document is taken to mean "commercially available amateur radio equipment" only. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and ETSI EN 301 489 1 [1], the provisions of the present document take precedence. The environment classification and the emission and immunity requirements used in the present document are as stated in ETSI EN 301 489 1 [1], except for any special conditions included in the present document. The applicable environments referred to in ETSI EN 301 489 1 [1] where equipment covered by the scope of the present document may be used, are to be declared by the manufacturer.
