ASTM E1958-98

Standard Guide for Sensory Claim Substantiation

SCOPE
1.1 This guide covers reasonable practices for designing and implementing sensory tests, which validate claims pertaining only to the sensory characteristics of a product. A claim is a statement about a product, which highlights its advantages, sensory attributes or differences compared to itself or other products to enhance its marketability. Attribute, performance, and hedonic claims, both comparative and noncomparative, are covered. This guide includes broad principles covering selecting and recruiting representative consumer samples, selecting and preparing products, constructing product rating forms, test execution, and statistical handling of data. This guide was developed by expert practitioners in the field. The intent this guide is to disseminate good testing practices. Validation of claims should be made more manageable if the essence of this guide is followed.

Sensory Claim Substantiation
This standard is issued under the fixed designation E 1958; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
No format or standard for testing related to claim substantiation can be considered without a frame
of reference for where that format or standard would fit within the legal framework that surrounds the
topic. Tests are performed for three basic reasons:
(1)Todeterminehowaproductcomparestoanother,usuallyacompetitororearlierversionofitself;
(2)Toprovidetheabilityformarketingtousepositivereferencesintheirpresentationoftheproduct
to the consumer through advertising or packaging; and,
(3) To determine if a product actually performs within the scope of its intended use.
Whenever a claim is strong, it will be scrutinized closely by competition, and if found inconsistent
with a competitor’s test data, it could well be challenged in one or more forums. It may be challenged
at the National Advertising Division of the Council of the Better Business Bureau, Inc./National
Advertising Review Board (NAD/NARB), one or more networks, or in any of a variety of courts. No
single test design or standard test will prevent a challenge. The criteria used by each of the potential

This guide demonstrates what a group of professionals, skilled in the art of testing, considers
reasonable. This represents a more effective method for both the defendant and the challenger to
determine the viability of a claim. The keyword is “reasonable.” If a particular aspect of a test is not
reasonable for a specific application, it should not be used. Care should be taken to clearly define the
reasons and data supporting a deviation from the standard, as such a departure surely will be
scrutinized.Becauseofthenecessityofsuchdepartures,theword“should”isusedinthisguidewhere
other techniques may have application in certain unusual circumstances.Whenever a test protocol has
been completed, it should be critiqued for weaknesses in reasonability. If you find weaknesses, they
should be corrected, since your competition surely will point them out. But what is reasonable? There
is no specific answer to that question. What is reasonable will depend on the company making the
claim and its posture toward advertising. Some companies are aggressive; others are conservative. It
will depend on the nature of the claim and the status of the competitor, the magnitude of the
advertising campaign and the frequency of the advertisement’s exposure. It will be affected by market
pressures, such as timing, and of course, testing budgets, and the internal dynamics of a company’s
marketing and legal/regulatory approval departments. You can be certain that your competitor will
consider your test unreasonable. This consideration is a given and does not matter. What does matter
is that the forum reviewing your test considers it more reasonable than your competitor’s challenge.
