ČSN EN 13592 This European Standard specifies the general characteristics, test methods and requirements for sacks, bags and bin liners, made from plastic films, used for household waste collection, or household selective waste collection including the collection of biodegradable waste for organic recycling (biodegradation and composting). For the purpose of this European Standard biodegradable and compostable sacks, including ties if any, are those which comply with EN 13432. This European Standard applies only to sacks, bags and bin liners for which the first use is for household waste collection or household selective waste collection. This European Standard does not apply to sacks used to protect bins and that are not lifted at the emptying operation and thus do not require the same mechanical characteristics. NOTE - For editorial reasons, in this document the terms "sack" and "bag" are synonymous.

ČSN ETSI EN 301 489-1 V2.1.1 The present document covers the essential requirements of article 3.1(b) of Directive 2014/53/EU [i.1] and article 6 of Directive 2014/30/EU [i.2] for radio equipment and associated ancillary equipment, excluding broadcast receivers, in respect of ElectroMagnetic Compatibility (EMC). Where the present document is being used to evaluate the EMC performance of "combined radio and non-radio equipment", ETSI EG 203 367 [i.3] provides guidance upon the application of the various harmonised standards, including the present document, that could potentially apply to such equipment. Product dependent arrangements necessary to perform the EMC tests on dedicated types of radio communications equipment, and the assessment of test results, are detailed in the appropriate relevant radio technology parts of ETSI EN 301 489 series [i.13]. The present document, together with the relevant radio technology part, where required, specifies the applicable EMC tests, the methods of measurement, the limits and the performance criteria for radio equipment and associated ancillary equipment. In case of differences (for instance concerning special conditions, definitions, abbreviations) between part 1 of ETSI EN 301 489 series [i.13] and the relevant radio technology part of ETSI EN 301 489 series [i.13], the relevant radio technology part takes precedence. Technical specifications related to the antenna port of radio equipment and radiated emissions from the enclosure port of radio equipment and combinations of radio and associated ancillary equipment are not included in the present document. Such technical specifications are normally found in the relevant product standards for the effective use of the radio spectrum. The environment classification used in the present document refers to the environment classification used in: " CENELEC EN 61000 6 3 [i.4] and CENELEC EN 61000 6 1 [i.5] for the residential, commercial and light industrial environment; or " CENELEC EN 61000-6-2 [i.15] and CENELEC EN 61000-6-4 [i.14] for the industrial environment; or " ETSI TR 101 651 [i.6] for the telecommunication centre environment; or " ISO 7637 2 [8] for the vehicular environment. The EMC requirements have been selected to ensure an adequate level of compatibility for equipment intended to be used in the environments mentioned above. The levels, however, do not cover extreme cases which may occur in any location but with low probability of occurrence. The present document may not cover those cases where a potential source of interference which is producing individually repeated transient phenomena or a continuous phenomenon is permanently present, e.g. a radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference or the interfered part or both. Where none of the existing specific relevant radio technology radio parts covers the required conditions for a particular radio equipment/service e.g. in case of the initial introduction of a new radio service or a special application, the present document can be used for the purposes of testing to the EMC requirements set out in the present document. In all cases where a radio product falls within the scope of a specific relevant radio technology radio part of the standard, the relevant radio technology part takes precedence. Compliance of radio equipment to the requirements of the present document does not signify compliance to any requirements related to spectrum management or to the use of the equipment (licensing requirements). Compliance to the requirements of the present document does not signify compliance to any safety requirements. However, it is the responsibility of the assessor of the equipment to record in the test report any observations regarding the test sample becoming dangerous or unsafe as a result of the application of the tests called for in the present document. NOTE 1: The present document does not yet fully address the industrial environment and industrial equipment, including ISM equipment. These will be addressed in a future edition. NOTE 2: The immunity requirements in the present document may not reflect the severity of electromagnetic phenomena present in the industrial locations, in such cases different requirements may be more appropriate, see for example CENELEC EN 61000-6-2 [i.15].

ČSN EN 60034-18-42 Tato část souboru IEC 60034 stanovuje kritéria pro hodnocení izolačních systémů statorových/rotorových vinutí jednofázových nebo vícefázových střídavých strojů, které jsou vystaveny opakovaným impulzním napětím, generovaným např. měniči s pulzně šířkovou modulací (PWM). U těchto izolačních systémů se předpokládá, že během provozu odolají aktivitě částečných výbojů. Norma předepisuje elektrické kvalifikační a přejímací zkoušky na reprezentativních vzorcích, které ověří způsobilost pro provoz s napěťovými měniči. Popisuje rovněž systém doplňkové klasifikace, který stanovuje meze spolehlivých funkčních vlastností při napájení z měniče. I když se norma zabývá napěťovými měniči, připouští se existence jiných typů měničů, které mohou generovat opakovaná impulzní napětí. U takových měničů lze při zkouškách v případě potřeby použít podobný přístup. Kvalifikace izolačních systému nesmí být vyžadována u točivých strojů, které jsou napájeny z napěťových měničů pouze při rozběhu, a proto nejsou předmětem této normy.
