In the June 2009 A2LA newsletter (http://www.a2la.org/newsletters/June_2009_Newsletter.pdf, see page 11), they determined the minimum type A and type B contributors for electrical and microwave/RF uncertainty budgets. After looking at ours, I've come to the conclusion that we need to revamp ours. My question is how do you state the type A uncertainty for measurements which have a slope to them, e.g. a DC zener voltage standard? How do I get a type A uncertainty from artifact standards that are outsourced (such as standard resistors or thermistor mounts)? Does anybody have any example budgets based on the A2LA requirements they would like to share (you can sanitize your company name off of them if you wish) so I can see if mine are even close to being structured correctly, using the right distributions and having the right info being reported?
