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.

Overview

EN ISO 10390:2022 / ISO 10390:2021 defines a routine instrumental method for the determination of pH in soils, treated biowaste and sludge. The standard covers measurements in the range pH 2 to pH 12 using a glass electrode and a 1:5 (volume/volume) suspension of sample in either water (pH in H2O), 1 mol·L⁻¹ KCl (pH in KCl) or 0.01 mol·L⁻¹ CaCl2 (pH in CaCl2). It is applicable to all types of air-dried soil and treated biowaste samples and includes provisions for sludges and field-moist samples.

Key topics and requirements

Sample preparation

Use air-dried (or dried ≤40 °C) samples sieved to 2 mm; treated biowaste may be measured without pretreatment (larger test portions apply).
Typical test portion: at least 5 mL (use known-capacity spoon); for untreated treated biowaste, larger volumes (e.g., 60 mL into 300 mL liquid) are specified.

Suspension ratio and conditioning

Prepare a 1:5 volume suspension (sample:solution).
Shake/mix for 60 min ± 10 min, then allow to stand 1–3 h; avoid air ingress during equilibration.

Measurement

Use a pH-meter with temperature control and slope adjustment, and a suitable glass (or combined) electrode.
For pH > 10 use an electrode designed for that range or include a pH 12 buffer during calibration.

Reagents and calibration

Water with low conductivity, KCl (1 mol·L⁻¹), CaCl2 (0.01 mol·L⁻¹).
Use appropriate buffer solutions (examples: pH 4.00, 6.88, 9.22 at 20 °C) for calibration at 20 °C ± 2 °C; follow manufacturer instructions for meter/electrode care.

Validation and reporting

The standard includes precision information (repeatability/reproducibility data in Annex A) and specifies required test-report elements.

Applications and users

Environmental and soil testing laboratories performing routine soil pH determination.

Waste management and composting facilities characterizing treated biowaste and sludge.

Agricultural advisers, agronomists, researchers and regulatory bodies assessing soil chemistry, land application suitability and compliance.

Useful for quality control, agronomic recommendations, environmental monitoring and compliance with national/regional regulations.
