Together with CECC, BS9000 is a preferred standard for use in European military projects. Consequently, Isocom Ltd's approved devices are listed in the CECC "MUAHAG" preferred products list. The BS9000 approval is also recognised as meeting the equivalent criteria to those required by BS5750/IS09000/EN29000. The Company's customers can be assured of our commitment to stringent quality, reliability and inspection standards, as demonstrated by our existing approvals. Other customer specific options can also be offered. Isocom takes great effort to ensure accurate data, but regrettably cannot be held liable for any error on its website.
