Ọnụ ego FCC SAR

Na United States, FCC na-ahazi SAR n'okpuru 47 CFR Nkebi 2, ngalaba 2.1093. Ngwaahịa echere maka iji izugbe ga-enwerịrị oke SAR nke 1.6 mW/g nkezi karịa otu gram anụ ahụ n'akụkụ ọ bụla nke isi ma ọ bụ ahụ, yana 4 mW/g gbakọrọ karịa gram 10 maka aka, nkwojiaka, ụkwụ na nkwonkwo ụkwụ.

Na European Union, 1999/519/EC kwadoro oke mkpughe RF. Ụkpụrụ kwekọrọ ekwekọ na-ekpuchi ngwaahịa ndị a na-ahụkarị dịka ekwentị na ngwaọrụ RFID. Oke na ụzọ nke nlebanya mkpughe RF na EU yiri ma ọ bụghị otu na ndị nọ na US.
