I-BTF Testing Lab iyisikhungo sokuhlola esigunyazwe yi-China National Accreditation Service for Conformity Assessment (CNAS), inombolo: L17568. Ngemva kweminyaka yokuthuthuka, i-BTF inelabhorethri ehambelana nozibuthe kagesi, ilabhorethri yokuxhumana engenantambo, ilabhorethri ye-SAR, ilabhorethri yokuphepha, ilabhorethri yokwethembeka, ilabhorethri yokuhlola ibhethri, ilabhorethri yokuhlola amakhemikhali nezinye izindawo zokucwaninga. Inokuhambisana okuphelele kwe-electromagnetic, imvamisa yomsakazo, ukuphepha komkhiqizo, ukuthembeka kwemvelo, ukuhlaziya ukwehluleka kwezinto ezibonakalayo, i-ROHS/REACH namanye amakhono okuhlola. Ilebhu yokuhlola ye-BTF ifakwe izinsiza zokuhlola ezichwepheshile neziphelele, ithimba elinolwazi lokuhlola nochwepheshe bokunikeza izitifiketi, kanye nekhono lokuxazulula izinkinga ezihlukahlukene zokuhlola nezitifiketi. Sithobela izimiso eziqondisayo "zokulunga, ukungakhethi, ukunemba, kanye nokuqina" futhi silandela ngokuqinile izimfuneko ze-ISO/IEC 17025 yokuhlola kanye nohlelo lokuphatha ilabhorethri yokulinganisa yokuphathwa kwesayensi. Sizibophezele ekunikezeni amakhasimende isevisi yekhwalithi ephezulu kakhulu. Uma unemibuzo, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi.
