Merilni postopki za ocenjevanje stopnje specifične absorpcije pri izpostavljenosti ljudi elektromagnetnim sevanjem brezžičnih komunikacijskih naprav, ki se držijo v roki ali pritrdijo na telo - 1528. del: Modeli človeka, instrumenti in postopki (frekvenčno območje od 4 MHz do 10 GHz)
Ta dokument določa protokole in preskusne postopke za standardizirano in ponovljivo merjenje konservativnega največjega prostorskega povprečja izpostavljenosti SAR (psSAR), induciranega znotraj poenostavljenega modela glave in telesa z radiofrekvenčnimi (RF) oddajnimi napravami, z opredeljeno merilno negotovostjo. Ti protokoli in postopki veljajo za veliko večino prebivalstva, vključno z otroki, pri uporabi komunikacijskih naprav, ki se držijo v roki ali pritrdijo na telo. Te naprave imajo enega ali več oddajnikov oziroma anten in delujejo s svojimi sevalnimi strukturami na razdaljah do 200 mm od človeške glave ali telesa. Ta dokument se uporablja za oceno skladnosti SAR različnih vrst brezžičnih komunikacijskih naprav, ki se uporabljajo ob ušesu, pred obrazom, so nameščene na telesu, delujejo v povezavi z drugimi napravami ali dodatki (npr. sponke za pas), ki oddajajo ali ne oddajajo radiofrekvenčne energije, ali so vdelane v oblačila. Naprave delujejo v frekvenčnem območju od 4 MHz do 10 GHz. Naprave, ki delujejo v ustreznem frekvenčnem območju, je mogoče
preskusiti z uporabo fantomov in drugih zahtev, opredeljenih v tem dokumentu.
Zajete kategorije naprav med drugim vključujejo mobilne telefone, brezžične mikrofone in radijske oddajnike v osebnih, namiznih in prenosnih računalnikih za večpasovne operacije z uporabo ene ali več anten, vključno z napravami PTT (push-to-talk). Ta dokument je mogoče uporabiti tudi za naprave za brezžični prenos energije, ki delujejo pri frekvenci več kot 4 MHz.
Ta dokument se ne uporablja za vsajene medicinske pripomočke
