Reporting of the method of analysis used
Poročanje o uporabljeni analitski metodi
In general a single method of analysis is established for the determination of each substance in feed.
Na splošno je za določanje vsake snovi v krmi določena ena sama metoda.
Where several methods are given, the particular method used by the control laboratory must be indicated on the analysis report.
Kadar je določenih več metod, mora kontrolni laboratorij v poročilu o analizi navesti, katero metodo je uporabil.
Number of determinations
Število določanj
The result given in the analysis report shall be the average value obtained from at least two determinations, carried out on separate portions of the sample, and of satisfactory repeatability.
Rezultat, naveden v poročilu o analizi, je srednja vrednost vsaj dveh določanj z zadovoljivo ponovljivostjo, izvedenih na ločenih vzorčenih deležih.
However, in case of the analysis of undesirable substances, if the result of the first determination is significantly (> 50 %) lower than the specification to be controlled, no additional determinations are necessary, on the condition that the appropriate quality procedures are applied.
Vendar pri analizi nezaželenih snovi, če je rezultat prvega določanja bistveno (> 50 %) nižji od specifikacije, ki se nadzira, dodatna določanja niso potrebna, če so bili uporabljeni ustrezni kakovostni postopki.
In case of the control of the declared content of a substance or ingredient, if the result of the first determination confirms the declared content, i.e. the analytical result falls within the acceptable range of variation of the declared content, no additional determinations are necessary, on the condition that the appropriate quality procedures are applied.
Pri nadzoru navedene vsebnosti snovi ali sestavine, če rezultat prvega določanja potrdi navedeno vsebnost, tj. rezultat analize je znotraj sprejemljivih meja odstopanja navedene vsebnosti, dodatna določanja niso potrebna, če so bili uporabljeni ustrezni kakovostni postopki.
In some cases this acceptable range of variation is defined in legislation such as in Council Directive 79/373/EEC.5.
V nekaterih primerih je ta sprejemljiva meja odstopanja opredeljena v zakonodaji, kot je Direktiva Sveta 79/373/EGS.5.
Reporting of the analytical result
Poročanje o rezultatih analize
The analytical result shall be expressed in the manner laid down in the method of analysis to an appropriate number of significant figures and shall be corrected, if necessary, to the moisture content of the final sample prior to preparation.
Rezultat analize se prikaže tako, kakor je navedeno v analitski metodi, na primerno število decimalk, in se po potrebi popravi glede na vsebnost vlage v končnem vzorcu pred pripravo.
Measurement uncertainty and recovery rate in case of analysis of undesirable substances
Nezanesljivost meritve in popravek za izkoristek pri analizi nezaželenih snovi
As regards undesirable substances within the meaning of Directive 2002/32/EC, including dioxins and dioxin-like PCBs, a product intended for animal feed shall be considered as non-compliant with the established maximum content, if the analytical result is deemed to exceed the maximum content taking into account expanded measurement uncertainty and correction for recovery.
V zvezi z nezaželenimi snovmi po Direktivi 2002/32/ES, vključno z dioksini in dioksinom podobnimi PCB, se proizvod, namenjen za živalsko krmo, šteje za neskladnega z določeno najvišjo vsebnostjo, če rezultat analize presega najvišjo vsebnost ob upoštevanju razširjene nezanesljivosti meritve in popravka za izkoristek.
In order to assess compliance, the analysed concentration is used after being corrected for recovery and after deduction of the expanded measurement uncertainty.
Za oceno skladnosti se uporabi analizirana koncentracija s popravkom za izkoristek, od katere se odšteje razširjena nezanesljivost meritve.
This procedure is only applicable in cases where the method of analysis enables the estimation of measurement uncertainty and correction for recovery (e.g. not possible in case of microscopic analysis).
Ta postopek se uporabi le v primerih, kadar analitska metoda omogoča oceno nezanesljivosti meritve in popravka za izkoristek (tj. ni možna na primer v primeru mikroskopske analize).
The analytical result shall be reported as follows (in so far the used method of analysis enables to estimate the measurement uncertainty and recovery rate):
O rezultatu analize se poroča (če uporabljena analitska metoda omogoča oceno nezanesljivosti meritve in popravka za izkoristek) na naslednji način:
corrected for recovery, the level of recovery being indicated.
s popravkom za izkoristek, pri čemer se navede raven popravka.
The correction for recovery is not necessary in case the recovery rate is between 90 % and 110 %;
Popravek za izkoristek ni potrebno uporabiti, če je 90–110-odstoten;
as ‘x +/- U’, whereby x is the analytical result and U is the expanded measurement uncertainty, using a coverage factor of 2 which gives a level of confidence of approximately 95 %.
kot „x +/– U“, pri čemer je x rezultat analize in U razširjena nezanesljivost meritve, ob uporabi faktorja za zajetje 2, zaradi katerega je stopnja zanesljivosti približno 95 %.
However, if the result of the analysis is significantly (> 50 %) lower than the specification to be controlled, and on the condition that the appropriate quality procedures are applied and the analysis serves only the purpose of checking compliance with legal provisions, the analytical result might be reported without correction for recovery and the reporting of the recovery rate and measurement uncertainty might be omitted in these cases.
Vendar če je rezultat analize bistveno (> 50 %) nižji od specifikacije, ki se določa, in je bil uporabljen ustrezni kakovostni postopek ter je namen analize le preverjanje skladnosti z zakonodajnimi določbami, se lahko rezultat analize poroča brez popravka za izkoristek, popravek za izkoristek in nezanesljivost meritve pa se lahko v teh primerih izpustita.
