ILebhu yoVavanyo lwe-BTF liziko lovavanyo elivunyiweyo yiNkonzo yeSizwe yoQinisekiso lwaseTshayina yoVavanyo lokuThobela (CNAS), inombolo: L17568. Emva kweminyaka yophuhliso, i-BTF inelabhoratri ehambelana ne-electromagnetic, ilabhu yonxibelelwano engenazingcingo, ilebhu yeSAR, ilebhu yokhuseleko, ilebhu yokuthembeka, ilebhu yovavanyo lwebhetri, uvavanyo lwekhemikhali kunye nezinye iilabhoratri. Inonxibelelwano olugqibeleleyo lwe-electromagnetic, amaza onomathotholo, ukhuseleko lwemveliso, ukuthembeka kokusingqongileyo, uhlalutyo lokusilela kwezinto, i-ROHS/REACH kunye nobunye ubuchule bokuvavanya. ILebhu yoVavanyo lwe-BTF ixhotyiswe ngamaziko ovavanyo abuchwephesha kunye apheleleyo, iqela elinamava ovavanyo kunye neengcali zesatifikethi, kunye nokukwazi ukusombulula uvavanyo oluntsonkothileyo kunye neengxaki zesiqinisekiso. Sithobela imigaqo ekhokelayo "yobulungisa, ukungakhethi buso, ukuchaneka, kunye nokungqongqo" kwaye silandela ngokungqongqo iimfuno ze-ISO/IEC 17025 yovavanyo kunye nenkqubo yolawulo lwelebhu yokulinganisa kulawulo lwezenzululwazi. Sizimisele ukubonelela abathengi ngeyona nkonzo iphakamileyo. Ukuba unayo nayiphi na imibuzo, nceda uzive ukhululekile ukuqhagamshelana nathi nangaliphi na ixesha.
