Surfactants shall be considered as readily biodegradable if the level of biodegradability (mineralisation) measured according to one of the five following tests is at least 60 % within 28 days: CO2 headspace test (OECD 310), carbon dioxide (CO2) Evolution Modified Sturm test (OECD 301B; Directive 67/548/EEC Annex V.C.4-C), Closed Bottle test (OECD 301D; Directive 67/548/EEC Annex VC(4E)), Manometric Respirometry (OECD 301F; Directive 67/548/EEC Annex VC(4D)), or MITI (I) test (OECD 301C; Directive 67/548/EEC Annex VC(4F)), or their equivalent ISO tests.
Površinsko aktivne snovi se štejejo za lahko razgradljive, če znaša odstotek biorazgradljivosti (mineralizacija), merjena v skladu z enim izmed petih preskusov, navedenih v nadaljevanju, najmanj 60 % v 28 dneh: analiza anorganskega ogljika v hermetično zaprtih posodah (CO2 headspace test) (vzorčenje iz parne faze) (OECD 310), prilagojeni Sturmov preskus sproščanja ogljikovega dioksida (CO2) (OECD 301B; Direktiva 67/548/EGS Priloga V.C.4-C), preskus zaprte steklenice (OECD 301D; Direktiva 67/548/EGS Priloga V.C.4-E), manometrična respirometrija (OECD 301F; Direktiva 67/548/EGS Priloga V.C.4-D), ali preskus MITI (I) (OECD 301C; Direktiva 67/548/EGS Priloga V.C.4-F), ali njim enakovredni preskusi po ISO.
Depending on the physical characteristics of the surfactant, one of the following tests might be used to confirm ready biodegradability, if the level of biodegradability is at least 70 % within 28 days: Dissolved Organic Carbon DOC Die-Away (OECD 301A; Directive 67/548/EEC Annex VC(4A)) or Modified OECD Screening DOC Die-Away (OECD 301E; Directive 67/548/EEC Annex VC(4B)), or their equivalent ISO tests.
Glede na fizikalne značilnosti površinsko aktivne snovi, se za potrditev lahke biorazgradljivosti, če znaša odstotek biorazgradljivosti najmanj 70 % v 28 dneh, uporabi eden izmed naslednjih preskusov: upadanje raztopljenega organskega ogljika (DOC) (OECD 301A; Direktiva 67/548/EGS Priloga V.C.4-A) ali prilagojeni izločilni preskus OECD — upadanje DOC (OECD 301E; Direktiva 67/548/EGS Priloga V.C.4-B), ali njim enakovredni preskusi po ISO.
The applicability of test methods based on measurement of dissolved organic carbon needs to be appropriately justified as these methods could give results on the removal and not on the biodegradability.
Uporabnost preskusnih metod, utemeljenih z merjenji raztopljenega ogljika, je treba ustrezno upravičiti, ker lahko te metode privedejo do rezultatov o odstranitvi in ne o biorazgradljivosti.
Pre-adaptation is not to be used in tests for aerobic ready biodegradability.
Predhodna prilagoditev se ne uporablja v preskusih za aerobno lahko biorazgradljivost.
The 10 days window principle shall not apply.
Načelo desetdnevnega okna se ne uporablja.
Anaerobic biodegradability
Anaerobna biorazgradljivost
Each surfactant used in the product shall be biodegradable under anaerobic conditions.
Vsaka površinsko aktivna snov, uporabljena v proizvodu, mora biti biorazgradljiva v anaerobnih pogojih.
Assessment and verification: the exact formulation of the product as well as a description of the function of each ingredient shall be provided to the competent body.
Ocenjevanje in preverjanje: pristojnemu organu se zagotovita točna formulacija proizvoda in opis funkcije vsake sestavine.
The DID list part A (Appendix I) indicates whether a specific surfactant is anaerobically biodegradable or not (the surfactants with an entry of ‘Y’ in the column on anaerobic biodegradability are biodegradable under anaerobic conditions).
Seznam DID del A (Dodatek I) navaja, ali je specifična površinsko aktivna snov anaerobno biorazgradljiva ali ne (površinsko aktivne snovi, pri katerih je v stolpcu za anaerobno biološko razgradljivost vnesen „Y“, so biorazgradljive v anaerobnih pogojih).
For surfactants which are not included in the DID list part A, the relevant information from literature or other sources, or appropriate test results, showing that they are anaerobically biodegradable shall be provided.
Za površinsko aktivne snovi, ki niso uvrščene na seznam DID del A, se uporabijo ustrezni podatki iz literature, iz drugih virov ali pa ustreznih rezultatov preskusov, po katerih so te snovi anaerobno biorazgradljive.
The reference test for anaerobic degradability shall be OECD 311, ISO 11734, ECETOC No 28 (June 1988) or an equivalent test method, with the requirement of a minimum of 60 % ultimate degradability under anaerobic conditions.
Referenčni preskus za anaerobno razgradljivost je OECD 311, ISO 11734, ECETOC št. 28 (junij 1988) ali enakovredna preskusna metoda, pri kateri se zahteva najmanj 60 % končne razgradljivosti v anaerobnih pogojih.
Test methods simulating the conditions in a relevant anaerobic environment may also be used to document that 60 % ultimate degradability has been attained under anaerobic conditions (see Appendix II).
Za dokazovanje, da je bila dosežena 60-odstotna končna razgradljivost v anaerobnem okolju, se lahko uporabijo tudi preskusne metode, ki posnemajo pogoje v zadevnem anaerobnem okolju (glej Dodatek II).
