Fertilizers and liming materials - Sampling and sample preparation - Part 2: Sample preparation (ISO 14820-2:2016)
ISO 14820-2:2016 specifies methods for the reduction and preparation of samples of fertilizers and liming materials and sets out the requirements for sample preparation reports. It also specifies methods for the preparation of test samples and test portions from laboratory samples of fertilizer for subsequent chemical or physical analysis. It does not cover the preparation of samples for certain physical tests which require test portions of more than 2 kg. It is applicable to all fertilizers.
NOTE The term "fertilizer" is used throughout the body of this part of ISO 14820 and is taken to include liming materials unless otherwise indicated.

Engrais et amendements minéraux basiques - Échantillonnage et préparation de l’échantillon - Partie 2: Préparation des échantillons (ISO 14820-2:2016)
La présente partie de l'ISO 14820 spécifie des méthodes de réduction et de préparation des échantillons d'engrais et amendements minéraux basiques et établit les exigences relatives aux rapports d'échantillonnage. Elle spécifie également des méthodes de préparation d'échantillons d'essai et de prises d'essai issues d'échantillons de laboratoire des engrais en vue d'une analyse physique ou chimique ultérieure. La présente norme ne couvre pas la préparation d'échantillons destinés à certains essais physiques nécessitant l'obtention de prises d'essai d'une masse supérieure à 2 kg. Elle s'applique à tous les engrais.
NOTE Le terme «engrais» est utilisé tout au long de la présente partie de l'ISO 14820 et prend en compte les amendements minéraux basiques, sauf indication contraire.
Gnojila in sredstva za apnjenje - Vzorčenje in priprava vzorcev - 2. del: Priprava vzorcev (ISO 14820-2:2016)
ISO 14820-2:2016 določa metode za zmanjšanje in pripravo vzorcev gnojil in sredstev za apnjenje ter določa zahteve za poročila o pripravi vzorcev. Poleg tega določa metode za pripravo preskusnih vzorcev in preskusnih količin iz laboratorijskih vzorcev gnojil za nadaljnje kemijske in fizikalne analize. Ne zajema priprave vzorcev za določene fizikalne preskuse, za katere so potrebne preskusne količine, večje od 2 kg. Uporablja se za vse vrste gnojil.
OPOMBA: Izraz »gnojilo« se uporablja v celotnem glavnem delu tega dela standarda ISO 14820 in vključuje tudi sredstva za apnjenje, če ni navedeno drugače.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
