Full title and description

Surface active agents — Detergents for hand dishwashing — Guide for comparative testing of performance. This International Standard gives guiding principles for designing comparative performance tests for solid and liquid household hand-dishwashing detergents, listing performance characteristics, test parameters and the basis for realistic comparative methods.

Abstract

Covers the principal considerations for assessing hand dishwashing products: (a) performance characteristics relevant to successive stages of washing; (b) the soiled articles required for assessing these characteristics; and (c) the washing processes to be employed. Lists primary and secondary variables affecting load and washing process and describes methods for assessment, reporting and interpretation of results.

Scope

Applicable to detergents sold for household hand dishwashing. The standard is intended to provide guidance for comparative tests that determine the consumer-relevant performance characteristics of solid and liquid hand-dishwashing detergents, including which soiled articles and washing processes to use and which variables to control.

Key topics and requirements

• Identification and definition of performance characteristics relevant to hand dishwashing (e.g., removal of food soils, rinsing behavior, foaming, ease of use).
• Specification of soiled test articles and soils to be used for comparative testing.
• Recommendations for washing procedures and control of primary and secondary variables (load, water temperature, mechanical action, contact times).
• Guidance on methods of assessment, measurement approaches and objective reporting of comparative results.
• Principles for interpreting comparative test data to permit fair ranking of products.

Typical use and users

Used by detergent manufacturers (product development and quality), independent testing laboratories, consumer-test organizations, regulatory bodies and standards committees that need reproducible comparative test procedures for hand-dishwashing products. The standard informs test design, method selection and reporting for comparative performance evaluations.

Related standards

Other ISO documents on surface-active agents and detergent testing are relevant, for example ISO 7535:1984 (guide for comparative testing of detergents for domestic machine dishwashing) and microbiological methods for liquid hand dishwashing (ISO 21703 series). Industry guides such as ASTM D8549 (guide for testing cleaning performance of hand dishwashing detergents) provide complementary test approaches. These documents are frequently consulted together when designing complete test programs.
