As long as it falls between those numbers it passes. All this was decided before production began to make a unit cost to produce.
And that is the same conditions used in the ISO 9000 and ISO 9001 certifications. Does a manufactured product meet the standards set during the design process? If it meets the design standards, that is all that matters.
As stated....products can be manufactured to both high and low standards which usually means higher and lower prices and both meet ISO standards.
