ČSN EN 17009 This document defines and specifies the relevant characteristics, requirements and appropriate assessment methods for determination of the suitability of floorings made with at least a top layer of lignified materials other than wood. This document covers solid and multi-layer flooring products for internal use and fully enclosed public transport premises. This document provides also additional product definitions, requirements for dimensional tolerances and other technical specifications for specific flooring products made of lignified material other than wood, such as: bamboo flooring products. This document covers products intended to be installed as self-supporting flooring or supported by battens on a subfloor or to be installed floating or glued on a subfloor. This document provides for the assessment and verification of constancy of performance and the requirements for marking these products. This document covers flooring products made of lignified materials other than wood which may or may not be treated to improve their reaction to fire performance or their durability against biological agents. This document does not apply to: - flooring products specifically manufactured for enhanced tactile and recognition; - wood flooring products covered by EN 14342; - laminate flooring products covered by EN 14041.

ČSN EN ISO 14851 This document specifies a method, by measuring the oxygen demand in a closed respirometer, for the determination of the degree of aerobic biodegradability of plastic materials, including those containing formulation additives. The test material is exposed in an aqueous medium under laboratory conditions to an inoculum from activated sludge. If an unadapted activated sludge is used as the inoculum, the test simulates the biodegradation processes which occur in a natural aqueous environment; if a mixed or pre-exposed inoculum is used, the method is used to investigate the potential biodegradability of a test material. The conditions used in this document do not necessarily correspond to the optimum conditions allowing maximum biodegradation to occur, but this document is designed to determine the potential biodegradability of plastic materials or give an indication of their biodegradability in natural environments. The method enables the assessment of the biodegradability to be improved by calculating a carbon balance (optional, see Annex E). The method applies to the following materials. - Natural and/or synthetic polymers, copolymers or mixtures thereof. - Plastic materials which contain additives such as plasticizers, colorants or other compounds. - Water-soluble polymers. - Materials which, under the test conditions, do not inhibit the microorganisms present in the inoculum. Inhibitory effects can be determined using an inhibition control or by another appropriate method (see, for example, ISO 8192[2]). If the test material is inhibitory to the inoculum, a lower test concentration, another inoculum or a pre-exposed inoculum can be used.

ČSN EN ISO 846 This document specifies methods for determining the deterioration of plastics due to the action of fungi and bacteria and soil microorganisms. The aim is not to determine the biodegradability of plastics or the deterioration of natural fibre composites. The type and extent of deterioration can be determined by a) visual examination and/or b) changes in mass and/or c) changes in other physical properties. The tests are applicable to all plastics that have an even surface and that can thus be easily cleaned. The exceptions are porous materials, such as plastic foams. This document uses the same test fungi as IEC 60068-2-10. The IEC method, which uses so-called "assembled specimens", calls for inoculation of the specimens with a spore suspension, incubation of the inoculated specimens and assessment of the fungal growth as well as any physical attack on the specimens. The volume of testing and the test strains used depend on the application envisaged for the plastic.
