Foreword

ISO (the International Organization for Standardization) is a worldwide federation ofnational standards bodies (ISO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized 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.

Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council.

International Standards ISO 7535 was developed by Technical Committee ISO/TC 91,Surface active agents, and was circulated to the member bodies in February 1983.

It has been approved by the member bodies of the following countries:

The member body of the following country expressed disapproval of the document on technical grounds:

0 Introduction

In order to test the comparative performance of detergents and rinse agents used in a number of domestic dishwashing machines, it is necessary to consider several related and several apparently unrelated variables. The particular variables and their importance will vary between regions and countries depending on

• the variety of soil, consequent on varied dietary habits;
• the materials used in making kitchen utensils,tableware and cutlery;
• water quality and limitations in the available choice of dishwashing machines.

Recognizing the importance and value to users of comparative test information derived from similarly based test methods, this International Standard lays down the criteria to be consideredin designing tests and assessing results. One of the primary criteria, which affect all consumers, is the effective removal of awide variety of soils from all kinds of domestic utensils soiled by foods and drinks, with the least possible damage to utensilsand to washing equipment. Another important criterion is the appearance of the cleaned utensils, such as, absence of spottingand filming

Although toxicological and ecological properties are extremely important for products widely used in the home, their assessmentis beyond the scope of this International Standard.

This International Standard shows how to devise satisfactory comparative test methods despite the possible choices between the dishwashing machines.

1 Scope

This International Standard establishes guidelines for carrying out comparative tests on machine dishwashing products solidor liquid, in an attempt to reflect realistically the performance of products likely to be used by consumers.

It lists and defines the performance characteristics considered ;it gives details of the variables to be taken into account, indicates their significance and provides a basis for designing adequate comparative test methods.
