For products with an applicable FDA mandatory radiation safety performance standard, are there any other standards that FDA will accept?
With the exception of the provision of Laser Notice 50 (http://www.fda.gov/cdrh/comp/guidance/1346.html), all products with an applicable standard must comply with the U.S. FDA’s standard before entering the U.S. or its territories. FDA does not recognize regulatory approvals from other countries or other organizations.
