ASTM E2346-09 PDF

1.1 This guide presents guidelines specific to the sensory evaluation of trigger hard surface cleaners. It covers the procedure for preparing a nonporous surface with the intent to measure one or all of the various aspects of a trigger product: package, application, performance, and after-use properties, with focus on visual, tactile, fragrance, performance, and package ergonomics. It is applicable for use with assessors, highly trained assessors, and consumers.

1.2 This guide for preparing nonporous hard surfaces is intended to focus on surface preparation and evaluation, not on panel selection, training, or development.

1.3 The reader should be aware that good sensory practices are required when preparing the surfaces, and in developing and training the assessors.

1.4 The researcher is responsible for identifying the most appropriate test design and using the appropriate statistical tool to address that experimental design.

1.5 Since this guide's intended use is to provide direction on the presentation and measurement of the different aspects of spray trigger hard surface cleaners, this guide may not accurately represent all possible soils and surfaces where spray trigger hard surface cleaners may be used.

1.6 This guide provides suggested procedures and is not meant to exclude alternate procedures that may be effectively used to provide the same results.

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory requirements prior to use.
