This leaves a substantial number of "specials" but it must be remembered that standardisation doesn't mean higher-cost specials; U means lowec-cost standard units. Aware that such a program is too ambitious for industry today, the author presents it at a basis for discussion, with the hope that power engineer# can agree 00 some similar set of standards. These would serve to guide equip ment selection for-new plant*, where eondition* permit freer, choice than in extensions and mod ernization*. In this way standardization would tend to come about naturally, and each forward step would be tested by experience. This will not be on easy job. The technical complexities are apparent. Not so apparent, but perhaps more important to success or fail ure, aro the problems imposed by the spread of interests Involved. Where Is the . common meeting ground for engineers of oil refineries and paper mills, chemical plants and steel milla, breweries and metal-working establishments? How can their needs and opinions be can vassed? Most important, who will take the lead in bringing these ioteresta together? Experience with large-turbine standardization reveals the advantages. Delay only farther com plicate* the problem. Let's laoklo it now! Read and wQigh the merits of Newman's pro posals; give some thought to ways in which you and your industry can wotk with other power engineers and industries to orrive ot mutually agreeable standard*. Let's have your commenta and ideas--Powbb will gladly serve as your clearinghouse and forum. -rC<;a-** U i- $1I 1 ii m W Yd 1fl lir'i: M ft, Ik V? K
