So our company produces raw sausage and I am updating our finished product spec sheets but I am having a hard time finding an industry standard for deviation in sizing. We use natural hog casings, which fluctuate in sizing from one end of the casing to the other (casing sizes are usually a range, ie 30/32mm, 35/38mm, etc.), and our portioning system works off the weight we set it to. My issue is, if we produce a 4oz link and the spec is 6.5in, what sort of deviation to that sizing is industry standard? Just off the tests I have run on our products, I am thinking somewhere between ±0.25-0.5in but I can't seem to find anything anywhere regarding any industry standards.
Does anyone have any experience with something like this, or point me in the right direction?
Please let me know. Thanks, all!
