(Main)Instant coffee — Sampling method for bulk units with liners (ISO 6670:2025)
- Abstract
1.1 This document specifies a sampling method for a consignment of instant coffee, shipped in 10 package units or more.
This document is applicable to cases which have inner linings of moisture-resistant material hermetically sealed because of the hygroscopic nature of instant coffee and which are in package units greater than 10 kg net mass, typically up to 50 kg. This document is also applicable to units of more than 50 kg, usually called “big bags” or “supersacks”. The cases are generally made of cardboard of appropriate strength and the big bags are made of suitable plastic material.
1.2 This document is also applicable to the selection and preparation of a sufficiently representative sample of the consignment, which is intended:
a) to serve as a basis for an offer for sale;
b) for examination to verify that the instant coffee to be offered for sale satisfies the producer’s sales specification;
c) for examination to determine one or more of the characteristics of the instant coffee for technical, commercial, administrative and arbitration purposes;
d) for retention as a reference sample for use, if required, in litigation.
1.3 This document is applicable to all types of instant coffee, as defined in ISO 3509, contained in all types of units with liners, with the exception stated in 1.4.
1.4 For bulk density and particle size, this document is applicable to spray-dried powder and freeze-dried instant coffees only, as defined in ISO 3509, due to the intrinsic fragility of particles of agglomerated instant coffee, which leads to greater breakdown and headspace in the final packed units for the consumer.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 15, Coffee.
