3、the requirements for due process, consensus, and other criteria for N at i on a I approval have been met by the standards developer. Standard Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affect
4、ed interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; thei

The American National Standards Institute does not develop standards and will in
6、no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute.

18、ICAN NATIONAL STANDARD ANSIINAPM lT4.24-1997 American National Standard for Photography (Processing) - Processing Trays and Tanks - Specifications 1 Scope 1.1 This standard sets forth the requirements for trays used in processing photographic sheet films, plates, or papers in sizes up to 50.8 cm x 6
19、1.0 cm (20 in x 24 in) described in ANSVNAPM IT1.18, ANSVNAPM IT1.72, and ANSI PHI .23. 1.2 This standard also provides specifications for tanks used in processing sheet films or plates up to 20.3 cm x 25.4 cm (8 in x 10 in) that are held in hangers described in ANSVNAPM lT4.22. 1.3 Two forms of tan
20、ks are recognized: (1) simple box-shaped tanks in which the hangers rest on the top edges, and (2) box-shaped tanks with flanged rims extending above the hanger ledge so that a cover may be used with the hangers in position. 2 Normative references The following standards contain provisions which, th
21、rough reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards and publications are subject to revision, and parties to agreements based on this American National Standard are encouraged to investig

Trays and tanks shall be constructed with sturdy materials so that they will not
25、warp or distort when Trays and tanks shall rest flat upon a flat surface. 1 ANSIINAPM lT4.24-1997 3.1.4 Trays and tanks shall be corrosion resistant to common photographic solutions (as tested in accordance with ANSI PH4.31) and shall have no deleterious effect upon sensitized materials or photograp
26、hic solutions. Solder shall not be used. 3.1.5 3.2 Tray requirements 3.2.1 Trays shall comply with the dimensions shown in figure 1. 3.2.2 When inside bottom surface ribs exist, they shall be smoothly and generously filleted for cleaning and shall not be more than 0.25 cm (0.10 in) high or deep in t
27、rays up to 35.6 cm x 43.2 cm (14 in x 17 in) or be more than 0.51 cm (0.20 in) high or deep in trays larger than 35.6 cm x 43.2 cm (14 in x 17 in). 3.2.3 Trays with pouring lips shall have the lip located in the particular corner shown in figure 1. The lip should be of the form shown and shall be ad
28、equately channeled to facilitate pouring. In sheet metal trays drawn from a symmetrical blank, the lip formed shall have similar pouring characteristics. 3.2.4 The top edges of the trays shall be formed in a rounded bead that is on the outside of the tray and is free from sharp edges. The bead shall
29、 not be completely closed; it shall be self-draining. 3.3 Tank requirements 3.3.1 3.3.2 3.3.3 below, the edge upon which the hanger bars rest. The interior surfaces of trays and tanks should be smooth so that they may be readily cleaned. The minimum inside dimensions of a tank shall comply with the
30、dimensions shown in figure 2. If inside fillets are used, they shall not exceed a radius of 0.64 cm (0.25 in). The rated volume shall be obtained with a solution level below, but not more than 2.5 cm (1 in) 4 Inch-millimeter conversion The SI units in this standard have been converted from U.S. cust
