Bonjour à Tous, Being an A2LA Assessor, I can provide this group insight to on a common (at least with this group of Assessors) approach that we adopted year's ago.
We decided that when a standard does not provide any tolerance on a specific parameter, we shouldn't cite any deficiency if the parameter is off by less than +/-5%.
