Each member body interested in a subject for which a technical committee has been established has liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission(lEC)onallmattersofelectrotechnicalstandardization. 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 International Standard may be the subject of patent rights.

International Standard ISO 18904 was prepared by Technical Committee ISO/TC 42, Photography This first edition cancels and replaces ISO 5769:1984, of which it constitutes a minor revision. This International Standard is one of a series of standards dealing with the physical properties and stability of imaging materialsd. To facilitate identification of these International Standards they are assigned a number within the block from 18900 — 18999 (see annex A).

Since lubrication is an additional step for processing laboratories, processed films are frequently left unlubricated, either intentionally or inadvertently. As a result, films may be irrepar
