You have to love those acronyms though. They conveniently named this one EFUP (EFFF-up) Which is totally appropriate. WE can put it right up there with FUBAR and SNAFU Have a great weekend, John John Burke (408) 515 4992 -----Original Message----- From: Leadfree [mailto:[log in to unmask]] On Behalf Of Ron Pickard Sent: Friday, January 19, 2007 3:42 PM To: [log in to unmask] Subject: [LF] China RoHS EFUP calculation? Is there anyone on this list able to figure out how to calculate the Technical EFUP (Technical Life Method) from the recently available China RoHS EFUP draft standard? What units is the term "Technical Life" in the equation (I'm assuming years)? Anyway, leaving all terms unitless I calculate a ridiculously small number using those equations. For example, using TL=10 & ADWT=0.75 (18hours/day) calculates to 0.037, or using TL-10 & ADWT=18 calculates an even smaller number. I'm wondering, is there something wrong with those equations correct or am I missing something? These equations appear to leave a lot to interpretation. All replies/comments are welcome.
