Wichtiger Entsorgungshinweis zu Batterien und Akkus
Jeder Verbraucher ist aufgrund der Batterieverordnung (Richtlinie 2006/66/
EG) gesetzlich zur Rückgabe aller ge- und verbrauchten Batterien bzw. Akkus
verpflichtet. Die Entsorgung über den Hausmüll ist verboten. Da auch bei Produkten
aus unserem Sortiment Batterien und Akkus im Lieferumgang enthalten sind, weisen
wir Sie auf folgendes hin:
Verbrauchte Batterien und Akkus gehören nicht in den Hausmüll, sondern können
unentgeltlich bei den öffentlichen Sammelstellen Ihrer Gemeinde und überall
dort abgegeben werden, wo Batterien und Akkus der betreffenden Art verkauft
werden. Weiterhin besteht für den Endverbraucher die Möglichkeit, Batterien und
Akkus an den Händler, bei dem sie erworben wurden, zurückzugeben (gesetzliche
Rücknahmepflicht).
Important disposal instructions for batteries and accumulators
EC Guideline 2006/66/EC requires users to return all used and worn-out batteries
and accumulators. They must not be disposed of in normal domestic waste. Because
our products include batteries and accumulators in the delivery package our advice is
as follows :
Used batteries and accumulators are not items of domestic waste. They must be
disposed of in a proper manner. Your local authority may have a disposal facility;
alternatively you can hand them in at any shop selling batteries and accumulators.
You can also return them to the company which supplied them to you; the company
is obliged to accept them.
Information importante pour l'élimination des piles et des accumulateurs
En vertu de la Directive européenne 2006/66/CE relative aux piles et accumulateurs,
chaque utilisateur est tenu de restituer toutes les piles et tous les accumulateurs
utilisés et épuisés. L'élimination avec les déchets ménagers est interdite. Etant donné
que l'étendue de livraison des produits de notre gamme contient également des piles
et des accumulateurs, nous vous signalons ce qui suit :
les piles et les accumulateurs utilisés ne sont pas des ordures ménagères, ils peuvent
être remis sans frais aux points de collecte publics de votre municipalité et partout
où sont vendus des piles et accumulateurs du type concerné. Par ailleurs, l'utilisateur
final a la possibilité de remettre les piles et les accumulateurs au commerçant auprès
duquel ils ont été achetés (obligation de reprise légale).
Belangrijke mededeling omtrent afvoer van batterijen en accu’s
Ledere verbruiker is op basis van de richtlijn 2006/66/EG verplicht om alle gebruikte
batterijen en accu’s in te leveren. Het is verboden deze af te voeren via het huisvuil.
Aangezien ook onze producten geleverd worden met batterijen en accu’s wijzen wij
u op het volgende; Lege batterijen en accu’s horen niet in het huisvuil thuis. Men
kan deze inleveren bij inzamelpunten van uw gemeente of overal daar waar deze
verkocht worden. Tevens bestaat de mogelijkheid batterijen en accu’s daar in te

Indicación importante acerca de la eliminación de pilas y acumuladores
Basado en la norma relativa a pilas/ baterías (directiva 2006/66/CE), cada consumidor,
está obligado por ley, a la devolución de todas las pilas/ baterías y acumuladores usados y
consumidos. Está prohibida la eliminación en la basura doméstica. Ya que en productos de
nuestra gama, también se incluyen en el suministro pilas y acumuladores, le sugerimos lo
siguiente:
Las pilas y acumuladores usados no pertenecen a la basura doméstica, sino que pueden
ser entregados en forma gratuita en cada uno de los puntos de recolección públicos de su
comunidad en los cuales se vendan pilas y acumuladores del tipo respectivo. Además, para
el consumidor final existe la posibilidad de devolver las pilas y baterías recargables a los
distribuidores donde se hayan adquirido (obligación legal de devolución).
Indicazioni importanti sullo smaltimento di pile e accumulatori
In base alla normativa concernente le batterie (Direttiva 2006/66/CE) ogni consumatore
è tenuto per legge alla restituzione di tutte le batterie o accumulatori usati ed esauriti. È
vietato lo smaltimento con i rifiuti domestici. Dato che anche alcuni prodotti del nostro
assortimento sono provvisti di pile e accumulatori, vi diamo di seguito delle indicazioni:
Pile e accumulatori esauriti non vanno smaltiti insieme ai rifiuti domestici, ma depositati
gratuitamente nei punti di raccolta del proprio comune o nei punti vendita di pile e
accumulatori dello stesso tipo. Inoltre il consumatore finale può portare batterie e
accumulatori al rivenditore presso il quale li ha acquistati (obbligo di raccolta previsto per
legge).
Instruções importantes para a eliminação residual de pilhas e acumuladores
Os utilizadores finais são legalmente responsáveis, nos termos do Regulamento relativo
a pilhas e acumuladores (Directiva 2006/66/CE), pela entrega de todas as pilhas e
acumuladores usados e gastos. É proibida a sua eliminação juntamente com o lixo
doméstico. Uma vez que determinados produtos da nossa gama contêm pilhas e/ou
acumuladores, alertamos para os seguintes aspectos:
As pilhas e acumuladores usados não podem ser eliminados com o lixo doméstico,
devendo sim ser entregues, sem encargos, junto dos pontos de recolha públicos do seu
município, ou em qualquer ponto de venda de pilhas e acumuladores. O utilizador final
dispõe ainda da possibilidade de entregar as pilhas e/ou acumuladores no estabelecimento
comerciante onde os adquiriu (dever legal de aceitar a devolução).
Istotna wskazówka dotycząca utylizacji baterii i akumulatorów
Każdy użytkownik na mocy rozporządzenia w sprawie baterii (wytyczna 2006/66/WE)
jest ustawowo zobowiązany do oddawania wszystkich rozładowanych i zużytych baterii
lub akumulatorów. Utylizacja wraz z odpadkami domowymi jest zabroniona. Ponieważ
także w produktach z naszego asortymentu zawarte są w zakresie dostawy baterie i
akumulatory, zwracamy uwagę na poniższe zasady:
zużyte baterie i akumulatory nie mogą być wyrzucane wraz z odpadkami domowymi,
lecz powinny być bezpłatnie przekazywane w publicznych miejscach zbiórki
wyznaczonych przez gminę lub oddawane w punktach, gdzie sprzedawane są baterie i
akumulatory danego rodzaju. Poza tym użytkownik końcowy ma możliwość zwrócenia
baterii i akumulatorów do przedstawiciela handlowego, u którego je nabył (ustawowy

1.1 Methods
The precision of Lovibond® Reagent Systems (tablets, powder packs and tube tests) is identical
to the precision specified in standards literature such as American Standards (AWWA), ISO
etc.
Most of the data referred to in these standard methods relates to Standard Solutions. Therefore
they are not readily applicable to drinking-, boiler- or waste-water, since various interferences
can have a major influence on the accuracy of the method.
For this reason we don’t state such potentially misleading data.
Due to the fact that each sample is different, the only way to check the tolerances (‘precision’)
is the Standard Additions Method.
According to this method, first the original sample is tested. Then further samples (2 to 4) are
taken and small amounts of a Standard Solution are added, and further results are obtained.
The amounts added range from approximately half, up to double the amount present in the
sample itself.
These supplementary results make it possible to estimate the actual concentration of the
original sample by comparison.
Literature
The reagent formulations are based on internationally recognised test methods. Some are
described in national and/or international guidelines.
