Dirvožemio kokybė. Dirvožemio užterštumo ekologinės rizikos vertinimo vietoje procedūra (dirvožemio kokybės vertinimo būdas TRIAD) (ISO/DIS 19204:2026)

ISO 19204:2017 describes in a general way the application of the soil quality TRIAD approach for the site-specific ecological risk assessment of contaminated soils. In detail, it presents in a transparent way three lines of evidence (chemistry, ecotoxicology and ecology) which together allow an efficient, ecologically robust but also practical risk assessment of contaminated soils. This procedure can also be applicable to other stress factors, such as acidification, soil compaction, salinization, loss of soil organic substance, and erosion. However, so far, no experience has been gained with these other applications. Therefore, this document focuses on soils contaminated by chemicals. NOTE 1 This document focuses on ecological risk assessment. Thus, it does not cover human health end points. In view of the nature of this document, the investigation procedure is described on a general level. It does not contain details of technical procedures for the actual assessment. However, this document includes references relating to technical standards (e.g. ISO 15799, ISO 17616) which are useful for the actual performance of the three lines of evidence. In ecological risk assessment, the effects of soil contamination on the ecosystem are related to the intended land use and the requirements that this use sets for properly functioning soil. This document describes the basic steps relating to a coherent tool for a site-specific risk assessment with opportunities to work out site-specific details. ISO 19204:2017 can also be used for the evaluation of clean-up operations, remediation processes or management measures (i.e. for the evaluation of the environmental quality after having performed such actions). NOTE 2 This document starts when it has already been decided that an ecological risk assessment at a given site needs to be performed. In other words, the practical performance of the soil quality TRIAD and the evaluation of the individual test results will be described. Thus, nothing will be said about decisions whether (and if yes, how) the results of the assessment are included in soil management measures or not. NOTE 3 The TRIAD approach can be used for different parts of the environment, but this document focuses mostly on the soil compartment. Comparable documents for other environmental compartments are intended to be prepared in addition (e.g. the terrestrial aboveground compartment) in order to perform a complete site assessment, based on the same principles and processes.

This document gives general requirements and tests for residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (hereafter referred to as RCBOs), for rated operational voltages not exceeding 440 V AC, with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A and rated short-circuit capacities not exceeding 25 000 A. RCBOs are intended to provide fault protection (previously referred to as protection against indirect contact), the exposed conductive parts of the installation being connected to an appropriate earth electrode. These devices are also intended to protect against overcurrents in the wiring installations of buildings and similar applications. They are also intended to be used to provide protection against fire hazards due to a persistent earth fault current. RCBOs having a rated residual operating current not exceeding 30 mA are used for fault protection and additional protection in the case of failure of the protective provisions against electric shock. This document applies to RCBOs performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value. These devices also perform the function of making, carrying and breaking overcurrents under specified conditions. RCBOs are intended to be operated by ordinary or uninstructed persons and designed not to require maintenance. The requirements of this document apply for standard conditions (see 7.1). Additional requirements can be necessary for RCBOs used in locations which have severe environmental conditions. RCBOs within the scope of this document are intended for use in an environment with pollution degree 2 (see 7.3). RCBOs are suitable for isolation. Special precautions (e.g. surge protective devices) can be necessary when excessive overvoltages are likely to occur on the supply side (for example in the case of supply through overhead lines, see IEC 60364-4-44 and IEC 60364-5-53). RCBOs, with the exception of those with an uninterrupted neutral, are suitable for use in IT systems. RCBOs of the general type are resistant to current surges, including the case where surge voltages (as a result of switching transients or induced by lightning) cause loading currents in the installation without occurrence of flashover. RCBOs of type S are considered to be sufficiently resistant against unwanted tripping even if the surge voltage causes a flashover and a follow-on current occurs. This document also applies to RCBOs obtained by the assembly of an adaptable residual current device with a circuit-breaker. The mechanical assembly is intended to be effected in the factory by the manufacturer, or on site, in which case the requirements of Annex G apply. It also applies to RCBOs having more than one rated current, provided that the means for changing from one discrete rating to another is not accessible in normal service and that the rating cannot be changed without the use of a tool. Particular requirements are necessary for RCBOs intended to be used at frequencies other than 50 Hz or 60 Hz. For RCBOs incorporated in, or intended for association with socket-outlets only, the requirements of this document can be used, as far as applicable, in conjunction with the requirements of IEC 60884-1 or the national requirements of the country where the product is placed on the market. This document does not apply to: .........
