Sunglasses (expired)

Declared unit

Dear PCR moderator,
The declared unit in this PCR does not take quality aspects into consideration. I would suggest expanding the declared unit into a functional unit where the typical life time of the sun glasses during normal ware and tare is taken into account.
Another option would be to require the declaration that certain minimum quality criteria have been met for the sun glasses (if standardized tests exist).
Best regards,
