Sensory analysis - General guidance for the selection, training and monitoring of assessors - Part 2: Expert sensory assessors (ISO 8586-2:2008)
ISO 8586-2:2008 specifies criteria for choosing people with particular sensory skills from selected assessors or from product, process or marketing specialists who themselves satisfy the selection criteria specified in ISO 8586-1. It specifies principles and procedures for choosing them and expanding their knowledge and abilities to the levels required of expert sensory assessors.
ISO 8586-2:2008 sets out requirements for expert sensory assessors to establish sensory profiles of products and materials through the use of descriptors. Specific knowledge of products or materials by expert sensory assessors is not necessary to fulfil these requirements.
ISO 8586-2:2008 supplements the information given in ISO 6658.

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 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 8586-2 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 12, Sensory
analysis.
This second edition cancels and replaces the first edition (ISO 8586-2:1994), which has been technically
revised.
ISO 8586 consists of the following parts, under the general title Sensory analysis — General guidance for the
selection, training and monitoring of assessors:
⎯ Part 1: Selected assessors
⎯ Part 2: Expert sensory assessors
ISO 8586-2:2008(E)
Introduction
Sensory assessment may be made by “assessors” (ISO 5492:2008, 1.5), “selected assessors”
(ISO 5492:2008, 1.6) and “expert sensory assessors” (ISO 5492:2008, 1.8). ISO 8586-1 specifies
requirements for the selection, training and monitoring of selected assessors. This part of ISO 8586 covers the
principles linked to selection, training and monitoring performance of expert sensory assessors.
This part of ISO 8586 does not deal with product experts or product-specialized experts, because their
specific know-how does not lie within sensory competence. However, a product expert or a product-
specialized expert who is trained as an expert sensory assessor can be considered as an expert sensory
assessor. This product-specialized expert can draw on additional knowledge gained in other fields, such as
knowledge of the product to be assessed, and process or marketing experience, in order to interpret sensory
data and make deductions.
An expert sensory assessor will have demonstrated particular acuity and reproducibility in panel work, and will
have developed a good long-term sensory memory, allowing reliable comparative judgements, when
necessary, in the absence of control samples.
Expert sensory assessors work as a panel which is managed by a panel leader. This panel leader is
responsible for the general monitoring of the group of expert sensory assessors and for their training. The
expert sensory assessors are not responsible for the choice of tests used, the presentation of the samples or
for the interpretation of results. These matters are the responsibility of the panel leader who also decides how
much information is given to the panel.

[ISO 3534-2:2006, 3.3.10]
3.5
reproducibility conditions
observation conditions where independent test/measurement results are obtained with the same method on
identical test/measurement items in different test or measurement facilities with different operators using
different equipment
[ISO 3534-2:2006, 3.3.11]
NOTE Reproducibility conditions may include different times (sessions), different environments, and different panels.
3.6
repeatability
precision under repeatability conditions
NOTE Repeatability can be expressed quantitatively in terms of the dispersion characteristics of the results.
[ISO 3534-2:2006, 3.3.5]
3.7
repeatability conditions
observation conditions where independent test/measurement results are obtained with the same method on
identical test/measurement items in the same test or measuring facility by the same operator using the same
equipment within short intervals of time
[ISO 3534-2:2006, 3.3.6]
NOTE Repeatability conditions mean same assessors (panel), same time (session), and same environment.
4 Selection of expert sensory assessors
4.1 General
Candidates for training shall:
a) already have shown aptitude for sensory analysis, as confirmed by reference to ISO 8586-1 — the best
first step is to choose selected assessors or to select people who are already selected assessors;
b) be motivated by an interest in further developing their sensory skills, in both the sensory methodology and
the sensory properties of one or several products;
c) be available for training and regular practice — a preliminary condition for expert sensory assessors is the
regular attendance at panel training programmes;
d) be volunteers.

ISO 8586-2:2008(E)
4.2 Specific skills
Panel leaders should evaluate the performance of the selected assessors, over a period of time and on the
products concerned. Any selected assessors who show good repeatability, noteworthy acuity, or particular
aptitude regarding specific attributes (e.g. a taint) of classes of materials, should be considered for use on
panels of expert assessors.
Moreover desirable characteristics of candidates include:
