ČSN EN IEC 61300-3-55 Norma stanovuje metody měření extinkčního poměru polarizace (PER) jednovidových optických součástek zachovávajících polarizaci (PM) založených na vláknech typu PM. Norma také stanovuje metody detekce vstupní a výstupní orientace hlavních os součástek PM, jakož i metody pro odhadování přesnosti klíčování, tj. úhlového vychýlení mezi hlavními osami a mechanickým referenčním vodicím klíčem konektorů, pokud ho obsahují. Norma obsahuje informativní přílohu A, která uvádí generování lineárních stavů polarizace, informativní přílohu B udávající přesnost klíčování pro vlákna PM a informativní přílohu C udávající srovnání mezi vypočtenými a naměřenými hodnotami extinkčního poměru.

ČSN EN IEC 62386-105 Tato část IEC 62386 platí pro ovládací zařízení. Obvykle sběrnicová jednotka podle IEC 62386 (soubor) obsahuje firmware. Existují okolnosti, kdy může být nutné změnit firmware po výrobě nebo odeslání produktu. Například pokud sběrnicová jednotka nefunguje tak, jak bylo zamýšleno. V takovém případě je výhodná aktualizace firmwaru sběrnicové jednotky přes rozhraní. Tento proces aktualizace firmwaru je primárně navržen jako proces opravy chyb, nikoli jako proces rozšíření funkcí. Proces aktualizace firmwaru však lze použít pro rozšíření funkcí. Je však důležité, aby bylo podrobně zváženo riziko negativních dopadů na celý systém.

Tyto metody mohou být použity v případě sporu mezi dvěma stranami, nejsou povinné pro řízení výroby. Jiná měřicí zařízení je možné použít, pokud lze prokázat, že jejich přesnost je stejná nebo lepší než přesnost uvedená v této normě. Je nezbytné, aby veškerá zařízení pro vážení, měření a zkoušení byla kalibrována nebo navázána na měřící standardy, pravidelně kontrolována podle zdokumentovaných postupů, četností a kritérií. Je důležité, aby vyjádření rozměrových charakteristik bylo v souladu s příslušnou třídou měřeného výrobku.

ČSN EN 13598-1 This document specifies the definitions and requirements for ancillary fittings and shallow chambers installed underground in non-pressure drainage and sewerage systems and manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) intended for use for: - non-pressure underground drainage and sewerage outside the building structure (application area code "U"), and - non-pressure underground drainage and sewerage for both buried in ground within the building structure (application area code "D") and outside the building structure. This is reflected in the marking of products by "U" and "UD". It also covers the jointing of the ancillary fittings and shallow chambers to the pipework system. The ancillary fittings covered by this standard are the following: - sealed access fittings; - rodding point covers; - rodding tees; - mechanical saddles. Ancillary fittings according to this document are intended for use in pedestrian areas, except rodding tees and mechanical saddles which can also be used in vehicular trafficked areas.

ČSN EN ISO 29200 The purpose of this International Standard is to describe a method for assessing genotoxic effects (chromosome breakage or dysfunction of the mitotic spindle) of soils or soil materials on the secondary roots of a higher plant: Vicia faba (broad bean). This method allows the assessment of genotoxicity (toxicity for genetic material) of soils and soil materials like compost, sludge, waste, fertilizing matters, etc. Two ways of exposure can be considered: a direct exposure of plants to the soil (or soil material) which is relevant for the real genotoxic potential and an exposure of plants to the water extract of the soil (or soil material). This last way of exposure to a leachate or an eluate allows the detection of the mutagens which are not adsorbed to soils and which may be transferred to aquatic compartments. Moreover, this test may be used to evaluate genotoxic effects of chemical substances and to waters, effluents, etc.

ČSN EN ISO 21285 This document specifies a chronic test method for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Hypoaspis aculeifer by - mainly - alimentary uptake. This method is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, industrial, agricultural or other sites under concern and waste materials (e.g. dredged material, municipal sludge from a wastewater treatment plant, composed material, or manure, especially those for possible land disposal). The reproduction (= number of juveniles) is the measured parameter of the test. The test reflects the bioavailability of a mixture of contaminants in natural soils (contaminated site soils) to a species which represents a trophic level which is not covered by other ISO standards. This test is not intended to replace the earthworm (see ISO 11268-2) or Collembola (see ISO 11267) reproduction tests since this species belongs not only to a different trophic group but also a different taxonomic group (= mites; i.e. arachnids) than those used usually. Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects are determined in the soil to be tested and in a control soil. Depending on the objective of the study, the control and dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (reference soil) or a standard soil (e.g. artificial soil). This document provides information on how to use this method for testing samples (soils or substances) under temperate conditions. This document is not applicable to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa at 25 °C. NOTE - The stability of the test substance cannot be ensured over the test period. No provision is made in the test method for monitoring the persistence of the substance under test.

ČSN EN ISO 14239 This document specifies six suitable incubation systems for measuring the rates and extent of mineralization of organic compounds in soil by measurement of carbon dioxide (CO2) evolution. All incubation systems are applicable to soluble or insoluble compounds but choice of system depends on the overall purposes of the study. This document does not apply to the use of such systems for material balance studies, which are often test-substance specific.

ČSN EN ISO 21286 This document specifies a protocol to identify ecotoxicological test specimens (mainly invertebrates and plants) to the species level, based on the DNA barcoding technique. This protocol can be used by laboratories performing DNA barcoding in order to standardize both the wet-lab and data analysis workflows as much as possible, and make them compliant with community standards and guidelines. This document does not intend to specify one particular strain for each test method, but to accurately document the species/strain which was used. NOTE 1 - This does not imply that DNA barcoding is performed in parallel to each test run, but rather regularly (e.g. once a year, such as reference substance testing) and each time a new culture is started or new individuals are added to an ongoing culture. This document does not aim at duplicating or replacing morphological-based species identifications. On the contrary, DNA barcoding is proposed as a complementary identification tool where morphology is inconclusive, or to diagnose cryptic species, in order to ensure that the results obtained from different ecotoxicological laboratories are referring to the same species or strain. This document is applicable to identifications of immature forms which lack morphological diagnostic characters (eggs, larvae, juveniles), as well as the streamline identification of specimens collected in field monitoring studies, where large numbers of organisms from diverse taxa are classified. NOTE 2 - In principle, all species regularly used in ecotoxicological testing can be analysed by DNA barcoding. Besides the earthwoms Eisenia fetida and E. andrei, further examples for terrestrial species are Lumbricus terrestris, L. rubellus, Allolobophora chlorotica, Aporrectodea rosea, and A. caliginosa, Dendrodrilus rubidus, Enchytraeus albidus, and E. crypticus (Haplotaxida); Folsomia candida, F. fimetaria, Proisotoma minuta, and Sinella curviseta (Collembola); Hypoaspis aculeifer and Oppia nitens (Acari); Aleochara bilineata and Poecilus cupreus (Coleoptera); Scathophaga stercoraria, Musca autumnalis (Diptera) or Pardosa sp. (Arachnida). Nematodes or snails and even plants can also be added to this list.
