Price based on 7 pages from IHS Not for Resale 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 ISoO 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, govern- mentat 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. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 2267 was prepared by Technical Committee ISO/TC 91, Surface active agents. This third edition cancels and replaces the second edition (IS0 2267-1979), of which it constitutes a minor revision. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. @ International Organization for Standardization, 1986 Printed in Switzerland Copyright International Organization for Standardization from IHS Not for Resal ISO 2267-1986 (E) INTERNATIONAL STANDARD Surface active agents -- Evaluation of certain effects of laundering --- Methods of preparation and use of unsoiled cotton control cloth 0 Introduction It also defines the conditions of use of this control cloth (in the form of control test pieces) during the laundering processes The quality of laundering for household textile articles may be which are being tested from the point of view of the conserv- ation of the original characteristics of the cloth. assessed in two different ways, depending on whether the cleaning effect, or the conservation of the initial characteristics of cloth subjected to repeated laundering, is under consider- The unsoiled cotton control cloth is primarily intended to ation. enable the laundering of white cloth to be tested.
