48 PRODUCTION MACHINING :: SEPTEMBER 2018 PARTS CLEANING :: Corrosion on nonferrous metals is caused primarily by reactions with corrosive gases, or what we call "atmospheric pollution." • Packaging, governmental and/or environmental regula- tions that will come into play, such as REACH, RoHS, TRGS regulations in Europe, and so on. • e time it will take to use, close and secure packaging. • Whether parts are packaged individually or in multiple parts per package. If it's one piece per package, can the design be changed to pack multiples and reduce packaging costs and environmental impact? • Shelf life or useful life considerations. • Personnel, and health and safety issues. • Total costs of the operation—not only direct costs, but incidental costs, too. • Safety Data Sheets (consideration of health and safety aspects of all materials). When packaging, a knowledge of the life cycle of the products being protected should be considered. If the parts can sit for an extended period, packaging materials with short shelf life should not be considered. Also, if the parts or assemblies will be traveling by, stored or used near the sea, care must be taken to ensure that the packaging material isn't affected by chlorides and provides a good moisture barrier. A knowledge of corporate, governmental, customer, or environmental regulations that govern recyclability, reusability or chemicals within the packaging materials also is essential. Packaging suppliers should provide, in writing, their packaging materials' ability to operate in the full tempera- ture range required (-40°F to 160°F, which covers air, sea and truck freight), and meet all appropriate environmental and governmental regulations, as well as their ability to be reused and recycled. e simple way to look at corrosion on metal is as a straightforward reaction:
