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.

This document specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction. This document has been developed largely for use in the field of environmental science, and its use in geotechnical investigations is something for which professional advice might be required.
A major objective of this document is the determination of enough size fractions to enable the construction of a reliable particle-size-distribution curve.
This document does not apply to the determination of the particle size distribution of the organic components of soil, i.e. the more or less fragile, partially decomposed, remains of plants and animals. It is also realized that the chemical pre-treatments and mechanical handling stages in this document could cause disintegration of weakly cohesive particles that, from field inspection, might be regarded as primary particles, even though such primary particles could be better described as aggregates. If such disintegration is undesirable, then this document is not used for the determination of the particle size distribution of such weakly cohesive materials.

ISO 9836:2017 specifies the definition and calculation of surface area and volume indicators.
In defining area measurement, ISO 9836:2017 uses three measurement concepts:
a) the intra-muros and extra-muros concept used in many parts of the world;
b) the wall centre method of measurement used in many parts of the world;
c) variations on these methods to comply with certain national laws or for particular types of buildings.
The surface area and volume indicators defined in ISO 9836:2017 are intended for practical use, as a basis for measuring various aspects of the performance of buildings or as a planning aid. In other words, they should enable judgement to be made on functional, technical and economic aspects of buildings.
ISO 9836:2017 is intended to be used when establishing
- specifications for the geometric performance of a building and its spaces (e.g. in design, purchasing procedures, etc., or in building regulations where appropriate),
- technical documentation relating to the performance of whole buildings prepared by designers, contractors and manufacturers,
- the amount of floor area that will not be effectively available for the placement of an individual's workplace, furniture, equipment, or for circulation, and
- evaluation, comparison or control of the properties of a building which are connected to its geometric performance.
NOTE Although there are a variety of methods of area measurement around the world depending on the country and/or types of buildings, all measuring methods are not necessarily of practical use because of inability to identify real area (e.g. the wall centre method of measurement). Thus, ISO 9836:2017 specializes in the measurement solely for practical use.
