Milk and milk products - Determination of alkaline phosphatase activity - Part 1: Fluorimetric method for milk and milk-based drinks (ISO 11816-1:2013)
ISO 11816-1|IDF 155-1:2013 specifies a fluorimetric method for the determination of alkaline phosphatase (ALP, EC 3.1.3.1) activity in raw and heat-treated whole milk, semi-skimmed milk, skimmed milk and flavoured milks. This method is applicable to milk and milk-based drinks from cows, sheep and goats. It is also applicable to milk powder after reconstitution.
The instrument can read activities up to 7 000 milliunits per litre (mU/l). If the activity is higher than 7 000 mU/l, it is diluted with alkaline phosphatase-free milk so as to obtain a measurement not higher than 7 000 mU/l.
Milch und Milcherzeugnisse - Bestimmung der Aktivität der alkalischen Phosphatase - Teil 1: Fluorimetrisches Verfahren für Milch und flüssige Milchprodukte (ISO 11816-1:2013)
Dieser Teil von ISO 11816 | IDF 155 legt ein fluorimetrisches Verfahren für die Bestimmung der Aktivität der alkalischen Phosphatase (ALP, EC 3.1.3.1) in Rohmilch und pasteurisierter Vollmilch, fettarmer Milch, Magermilch und aromatisierter Milch fest. Dieses Verfahren ist für Milch und flüssige Milchprodukte von Kühen, Schafen und Ziegen anwendbar. Es ist auch auf Milchpulver nach Rekonstituierung anwendbar.
Das Gerät kann Aktivitäten von bis zu 7 000 Milliunits je Liter (mU/l) auslesen. Wenn die Aktivität größer als 7 000 mU/l ist, dann ist mit Milch, die frei von alkalischer Phosphatase (7.1) ist, zu verdünnen, um ein Ergebnis kleiner als 7 000 mU/l zu erhalten.
Lait et produits laitiers - Détermination de l'activité de la phosphatase alcaline - Partie 1: Méthode fluorimétrique pour le lait et les boissons à base de lait (ISO 11816-1:2013)
L'ISO 11816-1|FIL 155-1:2013 spécifie une méthode fluorimétrique pour la détermination de l'activité de la phosphatase alcaline (ALP, EC 3.1.3.1) dans les laits crus et traités thermiquement entiers, demi-écrémés, écrémés et dans les laits aromatisés. La méthode est applicable au lait et aux boissons à base de lait de vache, de brebis et de chèvre. Elle est également applicable au lait en poudre après reconstitution.
L'appareillage peut lire des activités jusqu'à 7 000 milliunités par litre (mU/l). Si l'activité est supérieure à 7 000 mU/l, une dilution avec du lait exempt de phosphatase alcaline (7.1) est effectuée de façon à obtenir un mesurage ne dépassant pas 7 000 mU/l.
Mleko in mlečni proizvodi - Določevanje aktivnosti alkalne fosfataze - 1. del: Fluorimetrijska metoda za mleko in pijače na osnovi mleka (ISO 11816-1:2013)
Ta del standarda ISO 11816|IDF 155 določa fluorimetrijsko metodo za določevanje aktivnosti alkalne fosfataze (ALP, EC 3.1.3.1) v surovem in toplotno obdelanem polnomastnem mleku, delno posnetem mleku, posnetem mleku in aromatiziranem mleku. Ta metoda se uporablja za mleko in pijače na osnovi kravjega, ovčjega in kozjega mleka. Uporablja se tudi za mleko v prahu po pripravi. Instrument lahko beleži aktivnosti do 7000 milienot na liter (mU/l). Če je aktivnost višja od 7000 mU/l, se razredči z mlekom brez vsebnosti alkalne fosfataze (točka 7.1), da se pridobi meritev, ki ne presega 7000 mU/l.

ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non-governmental, in liaison with ISO, also take part
in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
