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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
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.
The committee responsible for this document is ISO/TC 174, Jewellery.
This second edition cancels and replaces the first edition (ISO 11210:1995), which has been technically
revised with the following changes:
— addition of an analytical balance in Clause 5;
— change of requirement for sampling in Clause 6;
— addition in 7.1 to allow dissolution in a sealed container under pressure;
— addition in 7.1 to allow drying of the crucibles in a programmable furnace;
— deletion of the temperature for reduction in 7.1;
— International Standard editorially revised.

Introduction
The following definitions apply in understanding how to implement an ISO International Standard and
other normative ISO deliverables (TS, PAS, IWA).
— “shall” indicates a requirement
— “should” indicates a recommendation
— “may” is used to indicate that something is permitted
— “can” is used to indicate that something is possible, for example, that an organization or individual
is able to do something
ISO/IEC Directives, Part 2 (sixth edition, 2011), 3.3.1 defines a requirement as an “expression in the
content of a document conveying criteria to be fulfilled if compliance with the document is to be claimed
and from which no deviation is permitted.”
ISO/IEC Directives, Part 2 (sixth edition, 2011), 3.3.2 defines a recommendation as an “expression in the
content of a document conveying that among several possibilities, one is recommended as particularly
suitable, without mentioning or excluding others, or that a certain course of action is preferred but not
necessarily required, or that (in the negative form) a certain possibility or course of action is deprecated
but not prohibited.”
