Geotechnical investigation and testing - Identification and classification of soil - Part 1: Identification and description (ISO 14688-1:2002)
ISO 14688-1, together with ISO 14688-2, establishes the basic principles for the identification and classification of soils on the basis of those material and mass characteristics most commonly used for soils for engineering purposes. The relevant characteristics may vary and therefore, for particular projects or materials, more detailed subdivisions of the descriptive and classification terms may be appropriate.
The general identification and description of soils is based on a flexible system for immediate (field) use by experienced persons, covering both material and mass characteristics by visual and manual techniques.
Details are given of the individual characteristics for identifying soils and the descriptive terms in regular use, including those related to the results of tests from the field.
ISO 14688-1 is applicable to natural soils in situ, similar man-made materials in situ and soils redeposited by man. The Identification and description of rocks is covered by ISO 14689.
The identification and classification of soil for pedological purposes, as well as in the framework of measurements for soil protection and for remediation of contaminated areas, is covered by ISO 11259.
Geotechnische Erkundung und Untersuchung - Benennung, Beschreibung und Klassifizierung von Boden - Teil 1: Benennung und Beschreibung (ISO 14688-1:2002)
Diese Norm stellt mit ISO 14688-2 die Grundprinzipien für die Benennung und Beschreibung sowie Klassifizierung von Böden auf der Basis der Eigenschaften dar, die gewöhnlicherweise für Böden im Bauingenieurwesen verwendet werden. Die relevanten Eigenschaften können variieren und es kann sein, dass für besondere Projekte und Materialien detailliertere Unterteilungen für die Benennung, Beschreibung und Klassifizierung erforderlich werden.
Die allgemeine Benennung und Beschreibung von Böden beruht auf einem flexiblen System für den sofortigen (Feld)-Einsatz durch erfahrene Personen, das sowohl die Eigenschaften von Boden als auch von Bodenbestandteilen umfasst, hauptsächlich mit visuellen und manuellen Techniken.
Zunächst werden die individuellen Eigenschaften zur Identifikation von Böden und die allgemein üblichen, beschreibenden Begriffe eingeführt, einschließlich derer, die auf Ergebnissen von Feldversuchen beruhen.
Das Anwendungsgebiet dieses Teils der ISO 14688 umfasst den natürlichen oder künstlichen Boden und ähnliches Auffüllungsmaterial. Die Benennung und Beschreibung von Fels werden in der ISO 14689 behandelt. Die Benennung, Beschreibung und Klassifizierung von Böden für bodenkundliche Aufgaben sowie im Rahmen von Maßnahmen zum Schutz der Böden und zur Sanierung von Altlasten erfolgen nach ISO 11259.
Recherches et essais géotechniques - Identification et classification des sols - Partie 1: Identification et description (ISO 14688-1:2002)
La présente partie de l'ISO 14688, conjointement avec l'ISO 14688-2, établit les principes fondamentaux de dénomination et de classification des sols, sur la base des caractéristiques du matériau et de ses composants les plus couramment utilisées par l'ingénierie géotechnique. Les caractéristiques concernées pouvant varier selon les projets ou matériaux, des subdivisions plus détaillées pour leur dénomination, leur description et leur classification peuvent être indiquées.
La dénomination et la description générales des sols sont basées sur un système souple pour utilisation immédiate (sur le site) par des personnes expérimentées, qui porte à la fois sur les caractéristiques du matériau et de ses composants et repose sur des techniques visuelles et manuelles.
Des détails sont donnés sur les caractéristiques propres permettant de dénommer les sols et les termes descriptifs régulièrement usités, y compris ceux qui se rapportent aux résultats des essais sur site.
La présente partie de l'ISO 14688 est applicable aux sols naturels en place, aux matériaux artificiels similaires aux sols en place, et aux sols mis en remblai. La dénomination et la description des roches sont traitées dans l'ISO 14689.
La dénomination et la classification des sols à des fins pédagogiques, ainsi qu'à des fins de mesurage pour la protection du sol et pour le traitement réparateur de zones contaminées, sont traitées dans l'ISO 11259.
Geotehnično preiskovanje in preskušanje - Prepoznavanje in razvrščanje zemljin - 1. del: Prepoznavanje in opisovanje (ISO 14688-1:2002)
Ta del standarda ISO 14688 skupaj s standardom ISO 14688-2 določa temeljna načela za prepoznavanje in razvrščanje zemljin na podlagi tistih značilnosti materiala in mase, ki se najpogosteje uporabljajo za namene gradbeništva. Pomembne značilnosti materialov se lahko razlikujejo in je zato pri nekaterih projektih in materialih primeren bolj natančen opis in opredelitev. Splošno določanje in opis zemljin temelji na fleksibilnem sistemu za neposredno (terensko) določanje s strani izkušenih oseb in vključuje značilnosti materiala in mase z uporabo vizualnih in ročnih tehnik. Podane so podrobnosti posameznih značilnosti za prepoznavanje zemljin in opredelitve v redni uporabi, vključno z rezultati testov na terenu. Ta del standarda ISO 14688 se uporablja za naravne zemljine na kraju samem, tem podobne umetne materiale in zemljine, ki so jih ljudje ponovno deponirali.. Prepoznavanje in opisovanje kamnin pokriva standard ISO 14689. Prepoznavanje in razvrščanje zemljin za pedološke namene in v okviru meritev za zaščito zemljin ter za sanacijo kontaminiranih območji pokriva standard ISO 11259.

Foreword
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Part 1:
Identification and description
1 Scope
This part of ISO 14688, together with ISO 14688-2, establishes the basic principles for the identification and
classification of soils on the basis of those material and mass characteristics most commonly used for soils for
engineering purposes. The relevant characteristics may vary and therefore, for particular projects or materials, more
detailed subdivisions of the descriptive and classification terms may be appropriate.
The general identification and description of soils is based on a flexible system for immediate (field) use by
experienced persons, covering both material and mass characteristics by visual and manual techniques.
Details are given of the individual characteristics for identifying soils and the descriptive terms in regular use,
including those related to the results of tests from the field.
This part of ISO 14688 is applicable to natural soils in situ, similar man-made materials in situ and soils redeposited
by man. The identification and description of rocks is covered by ISO 14689.
The identification and classification of soil for pedological purposes, as well as in the framework of measurements for
soil protection and for remediation of contaminated areas, is covered by ISO 11259.

3 Terms and definitions
For the purposes of this part of ISO 14688, the following terms and definitions apply.
3.1
soil
assemblage of mineral particles and/or organic matter in the form of a deposit but sometimes of organic origin, which
can be separated by gentle mechanical means and which includes variable amounts of water and air (and
sometimes other gases)

ISO 14688-1:2002(E)
NOTE 1 The term is also applied to made ground consisting of replaced natural soil or man-made materials exhibiting similar
behaviour, e. g. crushed rock, blast-furnace slag, fly-ash.
NOTE 2 Soils may have rock structures and textures may exist but soils are usually of lower strength than rocks.
3.2
identification of soil
naming and description of a soil on the basis of its grading, type of material and characteristics of mineral and/or
organic constituents and plasticity
3.3
geological structure
variation in composition including bedding and discontinuities
3.4
discontinuities
bedding planes, joints, fissures, faults and shear planes
3.5
organic matter
matter consisting of plant and/or animal organic materials, and the conversion products of those materials, e.g.
humus
NOTE Organic matter usually has a very high water content.
3.6
grading
measure of the particle sizes of a soil and their distribution
3.7
fraction
part of a soil that can be distinguished on the basis of defined particle sizes
3.8
plasticity
property of a cohesive soil to change its mechanical behaviour with change of water content
3.9
volcanic soils
pyroclastic materials produced and formed by explosive volcanic eruption; e.g. pumice, scoria, volcanic ash
4 Identification of soil
4.1 General
Subclauses 4.2 to 4.10 give soil characteristics that generally permit soil to be identified with adequate accuracy for
general (or preliminary) characterization. A more accurate identification and classification based on grading,
plasticity or organic content can be achieved by laboratory tests. In addition to identifying soils, the condition in which
a soil is encountered, any particular secondary constituents, other features of a soil, such as carbonate content,
particle shape, surface roughness of particles, odour, any common names and the geological classification should all
be indicated. For the identification and description, methods and additional tests shall be carried out according to
clause 5. The identification and description of soils generally follows the flow chart in Figure 1.

4.2 Particle size
Particle size is the fundamental basis for designating mineral soils using particle fractions to distinguish the soil
mechanical behaviour. Table 1 shows the terms to be used for each soil fraction and its sub-fractions, together with
the corresponding chosen range of particle sizes.
Basic soils are soils with uniform grading (i.e. they consist of particles of only one size range) as specified in Table 1
(e.g. gravel Gr, fine sand FSa, coarse silt CSi). The first letter of the abbreviation of the soil fraction is a capital.

4.3 Composite soils
4.3.1 General
Most soils are composite and consist of principal and secondary fractions. They are designated by a noun (main
term) describing the principal fraction and by one or more adjectives (qualifying terms) describing the secondary
fractions (e.g. sandy gravel saGr, gravelly clay grCl).
Composite soil terms shall be written with small letters.
Interlayered soils can be written in small underlined letters following the principal soil fraction (e.g. gravelly clay
interbedded with sand grClsa).
