11、made it imperative that designers and companies employ the very best procedures in selecting materials. The five most common faults in material selection have been: (1) failure to know and use the latest and best information available about the materials utilized. (2) failure to foresee, and take in
12、to account the reasonable uses for the product (where possible, the designer is further advised to foresee and account for misuse of the product, as there have been many product liability cases in recent years where the claimant, injured during misuse of the product, has sued the manufacturer and wo
13、n). (3) the use of materials about which there was insufficient or uncertain data, particularly as to its longterm properties. (4) inadequate, and unverified, quality control procedures. (5) material selection made by people who are completely unqualified to do so.,Material Selection,16,Lesson One,N
