Sludge, treated biowaste and soil - Determination of pH

This European Standard specifies a method for the determination of pH within the range pH 2 to pH 12 in a suspension of sludge, treated biowaste or soil in either water (pH-H2O), or a 0,01 mol/l calcium chloride solution (pH-CaCl2). This European Standard is applicable to sludge, treated biowaste and fresh or air-dry soil samples.

Schlamm, behandelter Bioabfall und Boden - Bestimmung des pH-Werts

Diese Europäische Norm beschreibt ein Verfahren zur Bestimmung des pH-Werts innerhalb des Bereichs
pH = 2 bis pH = 12, der in einer Suspension aus Schlamm, behandeltem Bioabfall oder Boden, entweder in
Wasser (pH H2O) oder in einer 0,01-mol/l-Calciumchloridlösung (pH CaCl2) gemessen wird.
Diese Europäische Norm ist auf Schlamm, behandelten Bioabfall und frische oder lufttrockene Bodenproben
anwendbar.

Boues, bio-déchets traités et sols - Détermination du pH

La présente Norme européenne présente une méthode de détermination du pH dans la plage comprise entre pH 2 et pH 12 dans une suspension de boue, de biodéchet traité ou de sol dans de l'eau (pH-H2O), ou dans une solution de chlorure de calcium à 0,01 mol/l (pH-CaCl2).
La présente Norme européenne s'applique aux échantillons de boues, de biodéchets traités et de sols frais ou séchés à l'air.

Blato, obdelani biološki odpadki in tla - Določevanje pH

Ta evropski standard določa metodo za določitev pH v razponu od pH 2 do pH 12 v suspenziji blata, predelanih bioloških odpadkov ali prsti v vodi (pH-H2O) ali 0,01 mol/l raztopine kalcijevega klorida (pH-CaCl2). Ta evropski standard velja za blato, predelane biološke odpadke in sveže oziroma na zraku sušene vzorce prsti.
