Sludge, treated biowaste and soil - Determination of pH

Le présent document présente une méthode de détermination du pH à l'aide d'une électrode en verre dans une suspension de boue, de bio-déchet traité ou de sol dilué à 1:5 (fraction volumique) dans de l'eau (pH-H2O) ou dans une solution de chlorure de calcium à 0,01 mol/l (pH-CaCl2).Il s'applique aux échantillons de boue, de bio-déchet traité ou de sol frais ou séchés à l'air.

Soil, treated biowaste and sludge - Determination of pH

This document specifies an instrumental method for the routine determination of pH within the range pH 2 to pH 12 using a glass electrode in a 1:5 (volume fraction) suspension of soil, sludge and treated biowaste in either water (pH in H2O), in 1 mol/l potassium chloride solution (pH in KCl) or in 0,01 mol/l calcium chloride solution (pH in CaCl2). This document is applicable to all types of air-dried soil and treated biowaste samples. NOTE For example, pretreated in accordance with ISO 11464 or EN 16179 or EN 15002.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
