L03 Slide 26 Pre-manufacturing/Material Choice (1,1) If any the following conditions apply, the matrix element rating is 0 : For the case where supplier components/subsystems are used: no/little information is known about the chemical content in supplied products and components. For the case where materials are acquired from suppliers : a scarce material is used where a reasonable alternative is available. (Scarce materials are defined as antimony, beryllium, boron, cobalt, chromium, gold, mercury, the platinum metals [Pt, Ir, Os, Pa, Rh, Ru], silver, thorium, and uranium.) If the following condition applied the matrix element rating is 4 : No virgin material is used in incoming components and materials. If neither of the preceding ratings is assigned, complete the checklist below. Assign a rating of 1 , 2 , or 3 depending on the degree to which the product meets DfE preferences for this matrix element. Is the product designed to minimize the use of materials in restricted supply? Is the product designed to utilize recycled materials or components wherever possible?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
