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 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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 16232-6 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 5, Engine tests.
ISO 16232 consists of the following parts, under the general title Road vehicles — Cleanliness of components of fluid circuits:
— Part 1: Vocabulary
— Part 2: Method of extraction of contaminants by agitation
— Part 3: Method of extraction of contaminants by pressure rinsing
— Part 4: Method of extraction of contaminants by ultrasonic techniques
— Part 5: Method of extraction of contaminants on functional test bench
— Part 6: Particle mass determination by gravimetric analysis
— Part 7: Particle sizing and counting by microscopic analysis
— Part 8: Particle nature determination by microscopic analysis
— Part 9: Particle sizing and counting by automatic light extinction particle counter
— Part 10: Expression of results...
