Isocom Ltd supplies high reliability devices for
applications requiring an operating temperature
range of -55°C to +125°C (e.g. military
applications).
Devices supplied are approved to BS9400, and have
completed rigorous testing. Various high reliability
test options are offered.
As a manufacturer of high reliability optocouplers,
the Isocom Ltd manufacturing plant in the North
East of England has site approval to BS9OOO
(registration number 1294/M) and CECC2OOOO
(registration number M/1084/CECC/UK) issued by
the British Standards Institution.
Together with CECC, BS9OOO 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.
