5、Resale, 05/09/2007 00:03:38 MDTNo reproduction or networking permitted without license from IHS -,-,- Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensu
6、s is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and obje
7、ctions be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or usi
8、ng products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpr
9、etation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or w
10、ithdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American Na

This standard is one of a series of standards establishing criteria of purity for chemi- cals used in processing photographic m
16、aterials. In the current review process, this series of standards is being updated and revised in format. Many of the standards in this series, but not all, also exist as standards of the International Organization for Standardization (ISO). The current updates and revisions are in accord with that
17、done for the ISO standards. In an effort to promote the concept of international stan- dardization, references to ISO standards have been left in place. Suggestions for the improvement of this standard will be welcome. They should be sent to the International Imaging Industry Association, Inc. (I3A)

23、n processing photographic materials. General test methods and procedures cited in this standard are compiled in Parts 1, 3, 5, and 8 of ISO 10349. This standard is intended for use by individuals with a working knowledge of analyti- cal techniques, which may not always be the case. Some of the proce
24、dures utilize caustic, toxic, or otherwise hazardous chemicals. Safe laboratory practice for the handling of chemicals requires the use of safety glasses or goggles and other protec- tive apparel such as rubber gloves, face masks, or aprons where appropriate.
