I imagine I am in the same position as many would be builders. I have 
completed my test piece OK but have to put Europa activities on hold 
while I put the house in order first. I remember some discussion of 
shelf life or epoxy materials (being good until they begin to get lumpy I 
think). Being concerned about avoiding this state I began putting the SP 
resin and hardeners in an insulated box to keep temperature even 
(presently from abt 9 degrees C to sometimes 40 degrees C in my work 
shed. right now at 11.30am Eastern Summer Time it is 35) and looked at 
the batch numbering to set them in first made first used order.

It seemed to me natural to think the first of the two numbers on the 
containers was a consecutive batch number and the second which follows 
the slash the year and month. As an example from my complete airframe 
epoxy supply, I have a container of resin and two containers of hardners 
as follows:

a container of resin 231680/9607
and
Std hardener 232102/9701
Slow hardener 233142/9607.

So the numbering assumption on std hardener destroyed my assumption.

Since the answer to this question should be of interest to many Europa 
non-builders like me, does anyone already know the answer please?
