BTF Testing Lab inzvimbo yekuyedza yakatenderwa neChina National Accreditation Service yeConformity Assessment (CNAS), nhamba: L17568. Mushure memakore ebudiriro, BTF ine electromagnetic inoenderana murabhoritari, isina waya yekutaurirana murabhoritari, SAR rabhoritari, kuchengetedza marabhoritari, kuvimbika marabhoritari, marabhoritari yekuyedza bhatiri, kuongororwa kwemakemikari uye mamwe marabhoritari. Iine yakakwana electromagnetic inoenderana, redhiyo frequency, kuchengetedzwa kwechigadzirwa, kuvimbika kwezvakatipoteredza, kuongororwa kutadza kwezvinhu, ROHS / REACH uye humwe hunyanzvi hwekuyedza. BTF Testing Lab yakashongedzerwa nehunyanzvi uye yakakwana yekuyedza zvivakwa, timu ine ruzivo yekuyedza uye nyanzvi dzezvitupa, uye kugona kugadzirisa kwakasiyana kwakaoma kuyedzwa uye matambudziko etifiketi. Isu tinoomerera kune inotungamira misimboti ye "kurongeka, kusarerekera, kurongeka, uye kuomarara" uye tinonyatso kutevedzera zvinodiwa ne ISO/IEC 17025 yekuyedza uye calibration laboratory manejimendi system yekutonga kwesainzi. Takazvipira kupa vatengi basa remhando yepamusoro. Kana uine mibvunzo, ndapota inzwa wakasununguka kutibata nesu chero nguva.
