The work of preparing International Standards is normaly carried out through IsO 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- mental 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 8212 was prepared by Technical Committee ISO/TC 91, Surface active agents. 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.

Accurate sampling is a difficult operation which requires much care. When it is necessary to obtain statistically valid informa- tion about a product, it is essential that the procedures de- 3.2 detergent scribed in this International Standard are followed. See term 2 of ISO 862. The manufacturer's responsibility for the satisfactory quality of a batch of product can only be established at the time of 3.3 batch: A definite quantity of material corresponding to manufacture. several sampling units which belong together because of their manufacture or production or packaging under conditions which are presumed to be uniform.
